01:55 GuShH holy crap https://www.youtube.com/watch?v=UcmaGMRD-Cs
02:01 GuShH this is what I was looking for... https://www.youtube.com/watch?v=YZDngpTmpzQ stupid youtube
02:03 GuShH somehow that was even more violent
03:36 KongfuPanda hello robotics people
03:38 Rif hi
03:38 KongfuPanda I was wondering if anyone knows a solution that can move give me a motor (+stuff) that I can just plug in the mains, and to the computer and tell it to rotate say a number of turns? thanks
03:39 Rif to do what?
03:40 joga KongfuPanda, usb motor controller + power supply + continuous rotation servos (is one possibility)
03:41 KongfuPanda Rif, I have a furnace ~ 10 kg, on a rail. There is a quartz tube with sample going through the furnace. At the moment I move the furnace myself to the right position and back. But I'd like this to be automated.
03:41 KongfuPanda I know about servo controllers and so on, I programmed AXON 2, hobby controller myself, and another EURO -something controller for a 3D microstage. But this time I don't have much time to do it, it's just a quick improvement thingy.
03:41 KongfuPanda joga, will I be able to tell how many revolutions it has done?
03:41 Rif steeper motor with a bike chain maybe, why does it need to be mains powered?
03:42 KongfuPanda Rif, because that's what is available in the lab, or USB. But I can't be bothered with batteries
03:42 joga KongfuPanda, hmm, you may need to implement that
03:42 Rif i guess any kind of rubber belt would just melt?
03:43 KongfuPanda Rif, no no, it's a furnace like this: http://selcukcvd.com/images/03.png
03:43 KongfuPanda but with a long tube
03:43 Rif well with a stepper motor and driver, you can tell it how many steps, there are many per revolution, and your problem is solved
03:44 joga yes stepper is good
03:44 Rif and some limit switchs to stop things if it goes wrong or to calibrate
03:45 Rif KongfuPanda, interesting, never seen or used a machine like that
03:45 joga you could probably salvage the parts from a printer or similar
03:45 KongfuPanda Rif, joga, I will fool-proof it in two ways: 1) motor needs to tell me how many revolutions it has done 2) I will use some kind of distance measuring device. Because I don't want the furnace to roll somewhere strange :D
03:45 KongfuPanda Rif, brb, I will take a picture of the actual rail and stuff. 5 mins
03:45 Rif KongfuPanda, your problem has been solved, now implement it
03:46 Rif you will know exact distance once you know the steps of your motor and drive gear
03:55 KongfuPanda Rif, I was thinking of some kind of chain. https://dl.dropboxusercontent.com/u/26776513/rail1.jpg https://dl.dropboxusercontent.com/u/26776513/rail2.jpg
03:55 KongfuPanda any better idea?
03:56 Rif nope, stepper and chain is what i'd be doin
03:57 KongfuPanda Ok, a stepper, chain. What else would I need?
03:57 Rif have a reprap have driving 5 steppers near 24 hours a day to 0.2mm accuracy, to move that thing back and forth would be easy
03:58 Rif a driver for the stepper, rated for more than the current the stepper motor needs, that has an easy interface to your pc
03:58 KongfuPanda would you be able to give me some links or websites where I can buy these things? (UK )
03:58 Rif a nema 23 stepper would be heaps i'd say, but costs more than nema 17
03:59 KongfuPanda I can probably convince the supervisor to spend ~ 200 pounds on this motorising this
03:59 Rif seach ebay or aliexpress for those to start
03:59 KongfuPanda I can't go with ebay
03:59 KongfuPanda I need a proper supplier
04:00 Rif hrm, i dunno, i have some mena17's, and have a name
04:00 Rif i just get stuff online
04:00 KongfuPanda ok, I'll google it
04:00 Rif nema 17 *
04:00 Rif where are you?
04:01 Rif what was the cheap stepper motor link posted today, its not on this pc
04:01 Rif ??
04:01 Rif was a real company
04:02 KongfuPanda in the UK
04:02 Rif 4 letter website.com
04:02 KongfuPanda we have a shop here, Maplin electronics
04:02 Rif ok far easyer for you to get local then, will be lots of places
04:02 Rif but you need chain and stuff, you think bike chain will do?
04:03 Rif i guess the smaller and better fitting the better
04:04 Rif but you only need to be within a mm or more so most should do the job
04:04 KongfuPanda no, within cm
04:04 Rif yep easy then
04:05 KongfuPanda ok, is it ok if I post links to products that I find here and get your approval? thanks
04:05 Rif heh hopefully someone else is awake as well, but post away
04:06 Jak_o_Shadows KongfuPanda: How heavy did you say it needed to move?
04:06 KongfuPanda Jak_o_Shadows, how do you mean? the weight of the motor is not an issue
04:07 Jak_o_Shadows No, the thing you're moving. Just thinking, that's your biggest problem, not control
04:07 Rif aren't you moving the whole furnace thing on the rails?
04:10 Jak_o_Shadows Of course, you could always add in a distance sensor just for peace of mind
04:11 Rif a tiny stepper motor from a smaller scanner would have issues with it
04:11 Rif limits switches are nice, am gonna add them on the other end of me repraps axis's
04:11 Rif crashed too many times
04:12 Jak_o_Shadows I'd probably find something that fits in the grooves, and mount the thing on the side of it. Then i'd do couple of gears mounted on the side of the furnace
04:12 Rif the homing limits switches are good and max travel is gonna be nicer
04:12 KongfuPanda Jak_o_Shadows, Rif, I put stopper bolts to stop it falling off
04:12 Rif mounting them will be easy yep
04:12 KongfuPanda I found this website, that is in the UK, it looks good, but too much choice
04:12 KongfuPanda http://uk.rs-online.com/web/c/automation-control-gear/electric-motors-motor-controllers-peripherals/stepper-motors/
04:13 KongfuPanda I have no idea what is the difference between those motors
04:15 Jak_o_Shadows concept: http://awwapp.com/s/32/9a/d5.html
04:15 Rif looks like ratshack, they will maybe have what you need but will cost heaps
04:16 KongfuPanda Jak_o_Shadows, excellent ! That what I was thinking about
04:16 Rif Jak_o_Shadows, nice drawing :)
04:16 theBear you gonna connect the switches as soft limits, or actual hw cutoffs ?
04:16 Jak_o_Shadows :D
04:17 theBear i often consider hard then soft, but with steppers it's pretty unusual for it to keep running if the software side has died
04:17 Rif theBear, ot if you reset, have had a few mishaps here
04:18 GuShH KongfuPanda: what sort of drugs does the furnace make?
04:18 KongfuPanda theBear, do you mean like put some sensors on side of the rail to turn everything off?
04:18 GuShH micro-switch
04:18 theBear generally microswitches or similar is used, they're nice and simple and easy to mount and a little 'soft'
04:18 GuShH or an optical interrupter
04:18 KongfuPanda :D sounds expensive
04:18 GuShH look up switches used on automated garages
04:18 GuShH they cost nothing
04:19 GuShH (garage doors)
04:19 GuShH sliding ones
04:19 theBear but either way, you can tell the software "oh no ! stop! you hit this end X/y/z" or just plain cutoff motor power/drive
04:19 KongfuPanda Let's go back to the main problem for a second
04:19 GuShH some use a "tilting" 3 position switch, others use a fixed micro-switch
04:19 KongfuPanda I will worry about fool-proofing later
04:19 GuShH KongfuPanda: if you are not qualified why are you on the job?
04:19 Jak_o_Shadows If you NEED confirmation of where it is, like a distance measurement independent from the stepper, it looks like a good surface to use an ultrasonic sensor on. You probably don't need this
04:19 KongfuPanda GuShH, I am qualified :D why am I not?
04:19 theBear cutoff way is guaranteed 'safe' but the software doesn't know about it.. also if they're 'soft' you can use them for powerup/reset calibration (run all steppers until you hit a switch, then you know where you are
04:20 GuShH you are asking on IRC how to move an object in a linear fashion
04:20 theBear most of the robot-lights i worked with over the years startup-calibrate like that, then so long as you don't miss steps you never hit an end stop
04:20 KongfuPanda GuShH, that's not what I was asking.
04:20 theBear and you don't need encoders
04:20 KongfuPanda GuShH, wanna see my robot?
04:20 GuShH not interested in maker crap
04:21 KongfuPanda GuShH, http://www.youtube.com/watch?v=4FxWpbLiw5g
04:21 GuShH use a cheap leadscrew or a couple bearings mounted on an I beam (even roller skate ones) and you can even use the linear gears they sell for garage automation and a simple gear mounted on the shaft of a fixed DC or stepper motor
04:21 GuShH on the carriage
04:22 GuShH this is the cheapest you can go, without requiring any welding (as you'd possibly need if you were to use bike parts)
04:22 GuShH there's hardly anything that simple
04:23 GuShH the common rails and gears are usually nylon or delrin
04:23 KongfuPanda Jak_o_Shadows, I see. I'll think about this. But as a first step, I need to but the stepper motor and driver, power supply, the pulleys, the chain. I was just looking for some suggestions of models etc
04:23 Rif KongfuPanda, nice hexapod, watch out for GuShH sometimes he bites
04:23 GuShH if you just need to move to a rough location a regular DC motor will do
04:23 GuShH no need for a stepper
04:24 GuShH H bridge to reverse
04:24 KongfuPanda GuShH, I'm more concerned about it being solid rather than cheap.
04:24 theBear good point, you HAVE been in a good mood recently mr GuShH, by which i mean not in a bad one :)
04:24 GuShH you just complained about micro switches sounding too expensive
04:25 GuShH And what I suggested is solid
04:25 theBear microswitches are dirt cheap
04:25 GuShH it's used to move half ton and bigger garage doors
04:25 GuShH the reason it's a good idea is rather simple, it's readily available and for non precision work it's enough
04:26 KongfuPanda I will go for a stepper motor, that can tell me the number of revolutions (as a first indication of distance) and to fool-proof it, I will get another solution to measure the distance, like what Jak_o_Shadows suggested: maybe a ultrasonic sensor
04:26 GuShH if you want solid, try to copy the carriage from a lathe and use a leadscrew like I said
04:26 GuShH but you probably don't have the tools to do this, most people don't
04:26 theBear leadscrew sounds heavy :)
04:26 GuShH the stepper itself can't tell you jackshit.
04:26 Rif it can with a controller and driver and we always said it needed that
04:27 GuShH you don't need to measure distance if there's no interruption and if there is, you reset to 0
04:27 GuShH in fact, you stop if there's an interruption.
04:27 theBear i wonder how accurately a driver could detect missed steps if it was designed to
04:27 GuShH upon startup you reset to 0 that's the simplest method
04:27 GuShH it's called registration
04:27 Rif i have not had a missed steps in millions on this thing here
04:27 Tom_itx the encoder needs to be finer than the steps
04:27 KongfuPanda :D
04:27 Tom_itx Rif, not even one?
04:27 GuShH you are making it more difficult than it has to be
04:27 KongfuPanda this turned into some big discussion now
04:28 theBear obviously there's current, but maybe sensing undriven coils or some kinda threshold of current vs model of normal drive vs slipping a step
04:28 GuShH KongfuPanda: go make bongs
04:28 Rif Tom_itx, durin testing and when i was accel to hard maybe, but now now, i see no defects
04:28 Rif apart from the drive screw maybe
04:28 GuShH theBear that's what fancy drivers are for, but the mere stepper won't provide anything and does not imply it's the only way of achieving this.
04:29 theBear nah, was just a distantly related question that came to mind
04:29 GuShH Me in a good mood? You've been misreading my signs!
04:29 Rif Tom_itx, getting nice parts now, making a 60k rpm turbine at moment
04:30 Rif and a spinning top that does about 20k
04:30 theBear nah, compared to a month ago you're positivily brimming with good cheer, back to normal... my normal aint exactly a good mood either, but ya know
04:30 ShH wonders why would anyone need one of t
04:31 Tom_itx something to stick your finger in
04:31 Rif GuShH, it can can and vacuum the dust at once, and just because i can
04:31 Rif can cut*
04:31 GuShH I still can't read that
04:31 Rif i will find a clip
04:31 KongfuPanda GuShH, I'll try to re-read your suggestion and make sure I understand.
04:31 theBear i can can and vacuum at once, and sometimes when i'm dusting i do that new york new york cossack style thing
04:31 GuShH KongfuPanda: I try not to google
04:32 Rif https://www.youtube.com/watch?v=SuztgGhTRg0&feature=player_embedded
04:32 darsie hi
04:33 GuShH KongfuPanda: seriously they make belt, chain and gear operated actuators for all sorts of doors.. it's readily available, works... why bother with homemade crap
04:33 KongfuPanda GuShH, so you are just basically saying to buy a garage automation solution?
04:34 KongfuPanda that may be an option
04:34 GuShH spend weeks fiddling with shitty schematics you've found off the net, wait for shippings to arrive, burn some stuff up, bitch about it, meanwhile you've got nothing working.
04:34 GuShH I'm saying look at what already exists and see if you can repurpose it to save time and money
04:35 GuShH theBear: I'm actually getting the lathe today... in a few hours I think
04:36 GuShH You could argue I've been exposed to lead for way too long (mood swings) or I'm just tired of most people... Maybe a combination of both?
04:36 GuShH Maybe even some other heavy metal poisoning?
04:36 Rif spinning top https://www.youtube.com/watch?v=6Wc73shHrsY&feature=player_embedded
04:36 Rif GuShH, you still don't have it?
04:36 GuShH Nope
04:37 Rif wow, did you find any tools?
04:37 GuShH Yesterday I talked with the store, got all the details down and left them my cell number... so in theory today morning it should arrive
04:37 GuShH I bought tools, but they never contacted me... and they never answered my mails... at this point if I call them I'll be very annoyed.
04:37 Rif i went to the dentist today and he found my source of phantom toothache
04:37 Rif some bit of crap stuck in the hole
04:37 GuShH I was just reading on phantom pains yesterday
04:38 GuShH But more to the point of missing limbs heh
04:38 GuShH Scary stuff.
04:38 GuShH Maybe I should suck on some lithium cells and see if that fixes the perceived bipolarity on me?
04:38 Rif can just imagine
04:38 ShH g
04:39 GuShH Actually I should try some lithium suplements, if such thing exists
04:39 GuShH in the form of carbonate, not a flashlight cell.
04:41 GuShH A little googling reveals they've used lithium salts in beverages up until 48
04:41 GuShH interesting
04:41 ShH wonders if theBear knew
04:42 KongfuPanda GuShH, I can't find anything suitable. I think I'll go back to making my own solution
04:43 GuShH you suck
04:43 KongfuPanda so childish
04:43 GuShH totally
04:43 GuShH pull my finger while you're at it!
04:44 GuShH KongfuPanda: look up the following "gate automation motor" and you'll find the rails, etc.
04:45 GuShH http://www.alibaba.com/product-gs/501875653/LOW_COST_600KG_SLIDING_GATE_AUTOMATION.html
04:45 GuShH http://www.alibaba.com/product-gs/731842005/Automatic_sliding_gate_motor_sliding_gate.html?s=p
04:45 GuShH some are tiny and it's all in there ready to be repurposed.
04:45 GuShH (forward, stop, backward, emergency stop switches)
04:45 GuShH there's backlash on these, but that shouldn't be a problem right?
04:45 GuShH it mainly comes from the way the gearbox is constructed
04:46 GuShH oh and they're mains operated.
04:46 GuShH direct 110 or 220
04:46 GuShH capacitor run motor
04:46 GuShH that's my childish idea for you.
04:47 Rif i bet he needs 2000 sets a month as well :)
04:47 GuShH heh alibaba is just a good reference for common stuff
04:47 GuShH you can find these at homedepot I bet
04:47 GuShH I've seen tiny ones for small gates
04:48 Rif yep its not a big thing though, mains power would be overkill
04:48 GuShH he also gets a wireless link built in
04:48 GuShH or he can easily interface to the mainboard
04:48 GuShH usually there's an extra channel in there
04:48 GuShH for a light or similar
04:49 Rif i got some big o rings today 4" cheaper to buy imperial in au than metric still for some weird reason
04:49 GuShH I'm just trying to figure out how you'd go about slowing it down without a VFD
04:49 Rif just for bigger tyres, the printed wheels won't care if they are metric or not
04:50 GuShH heh
04:50 GuShH I tend to abuse o-rings
04:51 Rif these are like 90c each. so worth it, 6.35mm wide, and round, or 1/4"
04:51 GuShH I have a box full of 10mm o-rings...
04:51 GuShH they are rather handy
04:52 Rif they make the best tires, will need to make a triple tire wheel for em
04:52 GuShH some silicone ones and some other bigger rubber ones, can't recall the sizes... dont' really have a full set of o-rings
04:52 GuShH I wonder what type of material the blue ones are
04:52 Rif i make the wheels about 5 to 6% bigger the the tire and rounded and they fit well without slipping
04:53 GuShH "fluorosilicone"
04:53 GuShH that's aerospace stuff right there!
04:53 GuShH heh no kidding they're not good for dynamic sealing, I have to replace them all the time
04:53 Rif http://imagebin.org/261864
04:54 Rif i got bearings for the turbine today and told old mate they had be go pretty fast
04:54 Rif he went yeah right when i said 60k, but they are rated to 100k in the book, nice jap ones
04:55 GuShH vacuum powered turbine tool .... you just found a way to waste 2kW to obtain under 200W
04:55 GuShH basic dremel is like 120W or 200W?
04:55 Rif yep, and wanna see what it can do with the air compressor
04:55 KongfuPanda has anyone here had experience with a motor+encoder combo?
04:55 GuShH you are so going to fail KongfuPanda.
04:56 GuShH waste of time.
04:56 GuShH Rif: well it's neat anyway, but rather wasteful
04:57 Rif GuShH, you can be so mean, he just wants to move a thing back and forth in a controlled manner. no rocket science
04:57 GuShH and I gave him a cheap, readily available solution that just works and can be easily adapter
04:57 GuShH adapted*
04:57 GuShH but he clearly wants to waste his and everyone's time with homemade crap
04:58 GuShH and it's going to bite him in the arse.
04:58 GuShH (because I've been through that stage)
04:58 KongfuPanda http://www.active-robots.com/motors-wheels/dc-motors/12vdc-encoder-motors
04:58 Rif well i'd say spend 100 on a nice computer controller stepper solution with end stops
04:58 GuShH that whole automation system is probably 100 or so in the US
04:58 Jak_o_Shadows purdy Rif
04:59 GuShH and now he wants to buy crap off of those "robotic" sites
04:59 GuShH awesome.
04:59 Rif anything but radioshack
04:59 GuShH radioshack wouldn't have any of this
05:00 Rif you don't need encoder motors
05:00 GuShH he won't listen let him fail on his own terms
05:01 KongfuPanda GuShH, can you go and do something useful with your time?
05:01 KongfuPanda Rif, why not? I thought they can tell me the number of rotations
05:01 GuShH KongfuPanda: certainly, I won't be buying shit off kiddy sites and pretending to be a robotics engineer just to move a chunk of steel a few centimeters in a linear motion
05:02 GuShH you are clueless and don't want any help, so you should go away.
05:02 Rif they can, and many thousands of ponts in between that you reeelly dont need
05:02 GuShH in fact you were given several solutions and ignored them all
05:02 KongfuPanda GuShH, I just don't like that gate moving thing. It's too powerful, not precise and huge for what I want
05:02 GuShH you don't know how to repurpose things, that's all
05:03 GuShH now precision is a key factor
05:03 KongfuPanda GuShH, maybe I lost some useful solutions when you flooded the channel with your crap
05:03 GuShH and before you said it wasn't.
05:03 GuShH you are full of it you don't even know what you want.
05:03 GuShH get your shit straight and come up with the right specs before you even consider browsing those kiddy sites
05:05 KongfuPanda what I asked initially was if someone know some solution, with two plugs: one to the mains, one to the computer, and that I can set a number of rotations on the computer and that's it.
05:05 KongfuPanda it seems something like that doesn't exist
05:05 KongfuPanda so we went on to talk about other options
05:06 GuShH go play with the arduino I'm not helping a clueless fool.
05:06 KongfuPanda I'm not asking you. I'd rather you go away and do something else
05:06 GuShH Go ahead kid
05:07 GuShH You'll clearly be quitting like you always do.
05:07 GuShH I won't be.
05:07 Rif yep that was the design spec, seems like it should be easy, but never is
05:07 GuShH He doesn't have a design spec
05:07 GuShH he wants to make bongs and is too baked to move it around himself
05:08 GuShH Join #arduino and you'll find others like you
05:08 Rif meanwhile these parts have printed well for the spinning top
05:08 Rif handy having the camera on the printhead
05:09 Rif cause it lives in a cardboard box because its cold
05:09 KongfuPanda GuShH, I've never used arduino
05:09 KongfuPanda I dunno how it works
05:09 GuShH Clearly
05:09 KongfuPanda want to explain?
05:10 GuShH Not really. I'd rather suck on a rusty nail
05:10 KongfuPanda :D
05:10 KongfuPanda you are funny
05:10 GuShH I think we've found a true mood-swinger, lithium anyone
05:10 KongfuPanda once I realized that you are a bit crazy, i can't really take you seriously
05:11 GuShH lol I won't even engage on that.
05:11 KongfuPanda FINALLY
05:11 GuShH GET OFF MY LAWN
05:12 GuShH KongfuPanda: between the stepper, interface and you learning how to use it all, you'll spend weeks if not months and not have anything done.
05:12 GuShH and that's not just being mean or an asshole, that's just how it is
05:12 GuShH there's a steep learning curve for most of these things and you can't cheat your way through it, unless you repurpose stuff like I suggested
05:12 GuShH and sure the arduino would do for you actually.
05:13 KongfuPanda I've used 3 micro stepper motors before simultaneously, and programmed a controller for them
05:13 GuShH that would give you the "pc interface"
05:13 GuShH and you can get a "stepper driver shield" for it
05:13 GuShH then is your problem only related to the mechanical engineering aspect?
05:13 KongfuPanda yes
05:13 GuShH or did you hit your head and forget it all.
05:13 KongfuPanda I'm not an engineer, I'm a physicist
05:13 GuShH So what tools do you have
05:14 GuShH you are as crazy as you say I am.
05:14 KongfuPanda I have a university workshop at hand
05:14 GuShH the bike chain and such will also have backlash and other problems, just like my gate idea.
05:15 GuShH if you want precision you can try using a leadscrew or you can use optical feedback on your ways and simply mount it all on bearings
05:15 GuShH using a belt to move it around
05:15 GuShH (think inkjet printer)
05:15 KongfuPanda I think something slightly fancier than a bike chain will work, I was looking some someone making these chains to size etc
05:15 KongfuPanda or even like a belt with little teeth
05:16 GuShH thing is finding a belt that suits your requirements that won't cost a fortune and be hard to find / replace
05:17 KongfuPanda yeah
05:17 GuShH you can gang up bike chains rather easily and get a certain degree of repeatability with them.
05:17 KongfuPanda oh, excellent idea
05:17 GuShH but for anything under a few millimeters of accuracy you should really try to mimic how an XY table works, or how a lathe carriage works.
05:17 KongfuPanda I can just join bicycle chains
05:18 KongfuPanda nah, I think ~ 5 mm accuracy is what I'm aiming for
05:18 KongfuPanda the chain should be ok for that
05:18 GuShH hard to say without knowing how much the load weighs
05:18 GuShH and how long you expect it to last
05:18 ShH b
05:19 KongfuPanda there is no resistance to move that furnace. I bet even a tiny motor with a small gear will be able to do it
05:19 GuShH go for a stepper with a reduction gearbox, couple it to the chain and see how well it works.
05:20 GuShH you can half-step (at a higher current cost) if you need a finer degree of accuracy
05:20 GuShH but then you get into several other problems
05:20 ShH now walks
05:22 KongfuPanda thanks :)
05:23 theBear hmmm, do old style non-electronic washing machines have a relay hidden somewhere, or the timer switch controls the motor directly ?
05:24 GuShH theBear how old?
05:24 GuShH they were directly connected
05:25 GuShH see if there isn't another timer switch hidden somewhere
05:25 GuShH same with very old microwave ovens, all mechanical and direct with beefy 10A or better timer switches!
05:25 theBear meh, should really just check the motor for coils, but assistant gone and i can't flip it
05:25 GuShH :<
05:26 GuShH heh even older they had a basic induction motor
05:26 GuShH belt driven usually!
05:26 theBear yeah belt, had it off and lubed it 5 mins ago
05:26 GuShH no fancy brake or anything
05:26 GuShH I kept one of those motors, they're powerful little buggers
05:26 theBear it's got a simple solenoid/transmission thing, but motor is just a motor
05:26 theBear well yeah, they spin a ton of water
05:27 GuShH newer machines use basically a vfd in there
05:27 theBear yeah, i'm quite familiar with smartdrive motor system
05:27 GuShH I don't like it
05:27 GuShH in fact newer washing machines are flimsy
05:27 GuShH I can't even wash 4 towels at once on this LG piece of crap
05:27 theBear it's good while it works, but these old style are bullet proof, unless you let an idiot use them
05:27 GuShH the previous one was an older Sanyo and you could probably wash yourself in it
05:27 GuShH Need new solenoids for it and some other parts
05:28 GuShH if it still works, been stored for ages.
05:28 GuShH should've thrown it away
05:28 GuShH hmm so who was the idiot in charge? heh
05:28 theBear either way, i really gotta wash some clothes.. sigh... middle of winter, raining, moist air, sigh
05:30 theBear i wonder, if it's got centrifugal start-signalling, a totally dead start cap could make the motor appear dead... sigh, it's all so hard when you can'
05:30 theBear can't err, strong
05:31 theBear stupid coffee machine died again, still got a million parts of projector spread all over the workbench...
05:31 eBear shakes
05:34 theBear to think, i used to fix things all day every day, now i can't keep up with my own stuff breaking down around me
05:35 KongfuPanda WOW, a "cable-pull" distance sensor !!! Perfettor
05:35 KongfuPanda perfetto*
05:36 theBear err, perfecto ?
05:37 KongfuPanda I guess
05:37 KongfuPanda how do you say in Italian
05:37 theBear yeah, the one i said
05:37 KongfuPanda naa, it's perfetto
05:38 theBear what you trying to say ?
05:39 theBear damn ! my one is spanish
05:39 theBear and i used to speak italian
05:39 theBear apparently used to being the operative part of the sentence
05:41 GuShH lol
05:41 GuShH my espresso seems to still work fine
05:41 GuShH but then again I don't let anyone use it
05:44 theBear noone uses mine, but it has worked at least once a day for maybe 10 years... few weeks ago it was just the series mains cap that killed the supply, now it seems to have 100% dead supply (externally, non-conclusive) instead of just one that cycles when it tries to switch stuff due to low-power... i did use secondhand parts... we'll see
05:44 GuShH speaking of which it's coffee time
05:44 GuShH oh need to get an RO filter... too expensive though :(
05:45 theBear RO ? gigs put me onto some stuff that cleans water, could be cool
05:45 theBear water here is pretty nasty, not stuff that clogs machines, just flavour/additives of other kinds
05:45 theBear www.homebrewtalk.com/f128/removing-metallic-flavors-beer-using-edta-156935/ that one
05:55 GuShH theBear: Reverse Osmosis with mineralizer stone
05:55 theBear yeah, that
05:56 GuShH without the mineral stone it's not really good for you
05:56 GuShH since it's virtually void of mineral
05:56 GuShH minerals
05:57 GuShH I mean you can drink it for a couple weeks, but not for years.
05:57 theBear well, coffee aint sposed to be good for you
05:57 GuShH heh but anyway a proper setup costs a lot here
05:57 GuShH and I don't think my water pressure is good enough for it
05:57 GuShH at least not in the kitchen, something must be stuck in the cold pipe
05:58 GuShH very low flow and reduced pressure
05:58 theBear bummer
05:58 GuShH not sure how to proceed heh
05:59 GuShH already fixed a low flow faucet / shower due to silicone that got stuck inside (someone must've used it to seal something and they put too much in)
06:00 GuShH but this other one beats me, I think the stopcock could be at fault or restricted
06:00 GuShH (they're old gate valve type)
06:01 theBear hehe you said stopcock
06:01 theBear blocking the rooster
06:06 GuShH sigh
06:06 GuShH theBear alright they call them sluice valves, you get the point...
06:08 theBear yeah, i know what stopcock and sluice means
06:08 GuShH I wasn't implying you didn't know
06:08 theBear just checkin
06:09 GuShH don't turn this into a ..... COCK FIGHT
06:09 theBear hehe, more of a pissing contest
06:09 GuShH pissing on roosters, I bet there's pr0n of that.
06:09 GuShH maybe even a whole industry around it
06:11 GuShH what is it with stores these days, no answer...
06:11 theBear yeah, they know consumers are so simple that they can basically ignore them completely and still not lose business
06:11 GuShH this other dude wanted his stuff fixed asap, it's been fixed since monday and now he doesn't have the money, so I have to wait 'til the end of the week
06:12 GuShH should've charged him more for being an asshole
06:13 GuShH theBear: did the fuse pop on the coffee machine? it's ok to admit it
06:13 GuShH do they still use a series cap?
06:13 GuShH reactance powah
06:13 theBear err, don't think it has a fuse... the mains stuff still goes, externally all i know is that there is no green/micro controlled light, and no motor control
06:13 GuShH should have at least one fuse!
06:13 theBear if i fiddle the mains SOMETIMES the green light flickers, not much tho
06:13 theBear i was pretty deep in it the other week, can't remember one
06:13 GuShH how come we have more standards than australia then
06:13 GuShH that doesn't add up
06:14 GuShH bah probe the mains wire :p
06:14 theBear actually, we have a lot of standards, and i DO know them... i think it SHOULD have a fuse
06:14 GuShH at least one fuse!
06:14 theBear meh, can't do much of anything without pulling the chassis out
06:14 GuShH so do it
06:14 theBear gotta get the 1000 pieces of projector off the bench first
06:14 GuShH I'll be your moral support until the lathe arrives
06:14 GuShH oh my "bench" is not a bench anymore
06:14 GuShH it's a jungle of stuff
06:15 GuShH I really need to get rid of all the crap and get everything all nice and tidy
06:16 theBear mmm, i just gotta get this projector back together, i think i finally found why the composite input doesn't work too, gotta look that up before i put the bulk back together, but i think i see enough to at least reassemble most of the optics
06:16 GuShH see I have a couple mini fridges that need a gas charge up and some fixing... maybe some paint too ... I can't justify selling them for a couple bucks
06:16 GuShH let alone throw them away
06:16 GuShH but they're taking up a lot of space
06:16 GuShH also that stupid safe the previous owner left in the house
06:16 theBear yeah, all of a sudden i start to feel that way about the stupid washer
06:16 GuShH I've been thinking about slicing it up but with a regular angle grinder it would take ages
06:16 GuShH oh but I could use one of those mini fridges heh
06:17 GuShH I just haven't found a place to buy cheap fittings
06:17 GuShH I'd try filling it up with butane first
06:17 GuShH it should work just fine... why bother with anything else.
06:18 GuShH I know there's a whole industry around refrigeration, that you need a specific type of refrigerant and a specific amount, etc... don't really think it applies when you just want to get it done heh
06:18 GuShH also I can pull a vacuum with another fridge compressor and it would be good enough for refilling it
06:19 GuShH I can solder a valve / fitting for that, but I need to find a place that sells them first
06:19 theBear meh, if yer prepared to go thru a few disks and got muscle you can chop anything up pretty quick... go HARD, just light enough to not burn out the engine, alternate between FAST and near-stall, like butter
06:19 GuShH those old fridges even the tiny ones were very rugged
06:19 theBear yeah, but an ankle biter in attack mode is heavy duty... if you got access to a huge size one, ooooh
06:19 GuShH I don't think anyone would buy that safe for other than scrap value or less than.
06:19 GuShH I don't, just regular black&decker
06:20 GuShH "pro" series (regular...)
06:20 GuShH 115mm I think it was, we pseudo established the other day
06:20 GuShH oh and cheap cutoff wheels are very very bad.
06:20 GuShH I actually confirmed it the other day
06:20 GuShH they don't cut worth crap.
06:21 GuShH must use dewalt, makita, etc. discs
06:21 GuShH 3mm is great for most things
06:21 GuShH I've got a 1mm for stainless that I had to use on regular tool steel... but oh well, it went like butter (except now it's been contaminated and I can't use it on stainless)
06:21 theBear yeah, regular size
06:22 GuShH had to cut a slot on a torx bit so I could use it with a regular flat head screwdriver
06:22 GuShH awesome idea.
06:22 theBear and when yer cutting metal seriously, you expect to go thru a disc every 5-10 minutes
06:22 GuShH I see a lot of potential in all the steel that safe has heh
06:22 GuShH but I think it's filled up with concrete or something worse in between layers
06:22 GuShH and that stuff would be nasty to cut indoors.
06:23 theBear mmm, more likely asbestos or something old and nasty :)
06:23 GuShH If anything people get the wrong idea when they see it, even after I show them it's just a shelf since it doesn't work as a safe
06:23 GuShH why asbestos?
06:23 GuShH fire proofing?
06:23 GuShH that could be worse indeed...
06:23 GuShH thought they would just have concrete or similar inside for strength and bulk
06:23 theBear asbestos insulates, hot or cold
06:24 GuShH I know... the water tank from the furnace is lined with it
06:24 GuShH but as long as I don't disturb it, should be ok.
06:24 GuShH I noticed the insulation on that thing is quite good though
06:24 GuShH it will keep the water at say 60°C for a day or two with just a few degrees drop
06:26 GuShH maybe new expanded foam tanks are a lot more efficient, I don't know...
06:26 GuShH I do know those will catch on fire very easily though
06:40 gwty Hello, does anyone know of a simple mechanism to make a robot trigger a water gun in a specific direction?
06:43 theBear erm, traditional water gun or prepressurized supersoaker style
06:43 gwty traditional water gun
06:44 theBear hmm, it'd need to be something a bit strong and fast to get a decent shot
06:44 theBear if power isn't an issue some kinda big solenoid could work
06:44 theBear otherwise maybe a real fast linear actuator
06:45 theBear or geared dc motor with a level
06:45 theBear lever
06:47 gwty okay, I was talking of something like this http://en.wikipedia.org/wiki/Foster-Miller_TALON
06:48 theBear jeez, that looks heavyduty
06:48 theBear so cute, but so deadly
06:48 theBear it's like a mini robocop 2
06:48 theBear aka ed209
06:51 gwty I thought it'd be nice to build a simple watergun-equipped version of it. How much will it cost approximately (Normal materials only)
06:52 Gargantuasauce just use a CO2 cannister or something
06:53 theBear depends, how good are you with electronics and mechanicalery ?
06:53 theBear that makes the difference between <$100 and several thousand... well, that and how much you prepared to learn/build
06:53 Jak_o_Shadows Still be a couple of hundred.
06:54 gwty CO2 cannister sounds good, but I haven't found one in India.
06:54 theBear get them at food supply places ... aka 'soda charger'
06:54 theBear 'cream charger' is the same but nitrous
06:55 gwty I am a CS person, not very good with electronics, mechanical stuff. Infact, I thought I could use openCV to auto-target and spray peoples' faces with water[Main purpose].
06:55 KongfuPanda Hello, Could someone tell me what electronics is needed for to read the "encoder" signal
06:55 Jak_o_Shadows Yeah, that's doable
06:55 theBear KongfuPanda, depends what the 'encoder' is
06:56 theBear well firstup, what you using for a motor ?
06:56 KongfuPanda suppose this one: http://www.active-robots.com/motors-wheels/dc-motors/12vdc-encoder-motors/gear-motor-encoder.html
06:56 theBear slow load slow load
06:57 theBear mmmk, so it's a dc motor with an unspecified decoder... dc motor means you don't know how 'far' it goes purely from drive
06:57 theBear hmm.. no datasheet ? that's a pretty shitty site
06:58 KongfuPanda there is a datasheet: http://www.active-robots.com/fileuploader/download/download/?d=0&file=custom%2Fupload%2FFile-1306926414.pdf
06:58 theBear impossible to say how to read it... generally you'd expect either a on/off signal, or more likely a on/off pulldown kinda thing, either of which would require a single digital input and maybe a pullup/transistor... but with that style encoder it only measures movement with on/off signals or pulses, so you gotta count EVERY one, if you miss one you're 'lost'
07:00 theBear hmm, still a poor datasheet, but it suggests 90deg offset style dual sensors, being halls and dual you'll need 2 digital inputs and 2 resistors.... you still can't miss a state change without losing position, and the patten will tell speed/movement amount AND direction...
07:01 theBear one direction will look like oo io ii oi oo and the other direction like oo oi ii io oo\
07:02 theBear also that's a small motor compared to the thing it's moving, but might be ok at lowish speeds with that much geargin
07:03 theBear and the hall supply is isolated from the motor connections, which means you can pwm /linear speed control within reason and still monitor accurately
07:04 theBear 72000 pulses/minute at slightly above nominal speed, so err, probably about 2k samplerate to be sure everything is cool
07:07 Tom_itx oo ee oo aa aa walla walla bing bang
07:08 theBear ma ma ooo mow mow ma ma oo oo ma mow
07:08 theBear bird bird bird bird is the word
07:08 theBear i thought everybody had hear
07:08 theBear d
07:10 KongfuPanda I see
07:10 KongfuPanda thanks
07:11 Tom_itx always here to help
07:12 theBear heh, and i thought everybody had heard
07:16 KongfuPanda hear what?
07:16 KongfuPanda about the bird? :D
07:18 theBear the bird is the word !
07:19 theBear http://www.youtube.com/watch?v=2WNrx2jq184
07:23 GuShH and KongfuPanda dares say I'm the crazy one
07:23 theBear hehe, always cracks me up when he's all dead on the floor, and he starts ba ba ba ooh mow mow baba oh mow mowmow
07:23 GuShH hmm brb
07:27 GuShH bah still no sign of the lathe
09:25 rue_house I missed the story, what kinda lathe you get?
09:40 GuShH rue_house: very similar to the one Rif has
09:40 GuShH but 750mm between centers
09:40 GuShH possibly made in the same factory for all I know, looks exactly the same
09:41 GuShH it should've been here hours ago... almost lunch time, no lathe. I'ma call these lazy bastards in a few minutes!
09:41 GuShH they said "first thing in the morning" and it's 11:27
09:42 GuShH sure there's fog out on the highway so what
09:42 GuShH they have my cell number, my landline and email addresses... no excuse to be so unprofessional.
11:06 wizrobe http://jddorweiler.appspot.com/car.html#car
11:06 wizrobe http://jddorweiler.appspot.com/car.html#car
11:21 Skwint You know that stuff called NeverWet?
11:21 Skwint super-hydro-phobic spray?
11:21 Skwint what happens to the friction/drag of a boat hull if you make it insanely hydrophobic? anyone know?
11:23 joga I'd like to try some of that stuff
11:28 Skwint me too. not cheap though.
12:47 GuShH RifRaf: lathes here... problem, I can barely move it!
12:47 GuShH already took the tailstock and steadies out, all of the contents in the box (4 jaw chuck etc) and the splash guard, still way too heavy... thinking about removing the 3 jaw chuck, is it threaded in or taper?
12:48 GuShH some surface rust behind the tailstock mount, looks like they forgot to oil that... the rest is covered in thick machine oil
12:48 GuShH seems well built for what it is, although I can clearly see some lacking portions
12:49 GuShH like the locking on the tailstock is just a nut instead of a lever, might have to cook something up for that since you only need a quarter to almost half a turn to free it up, so a lever could be used instead.
12:50 GuShH I can't imagine what it must be to move a half a ton lathe... jeez. I'm a bit annoyed at the fact that I didn't get the cabinet, box says 1/2 I bet the second box contained the pedestal
12:50 ShH will email these assholes to see what excuse they come up
12:50 GuShH I don't have a suitable workbench that can hold the weight and be stable
13:19 GuShH dang it! now the leafblower is crapping out at WOT
13:19 GuShH wonder if the fuel got old and degraded... I just mixed it with 2 stroke oil :(
13:21 GuShH plug looks good, a bit too lean though
14:00 KongfuPanda hi guys
14:01 KongfuPanda regarding my question earlier today, I will be getting this simple board: http://www.pc-control.co.uk/stepperbee_plus_info.htm and a stepper motor + power supply
14:01 KongfuPanda any advice where to buy budget unipolar stepper motor in the UK? thanks
14:11 GuShH KongfuPanda: eBay you clueless prick! :p
14:12 KongfuPanda GuShH, I don't trust :)
14:12 GuShH aw
14:12 GuShH why not? some sellers are OK you can always look them up
14:12 GuShH got no old printers to take apart? old copy machine... old fax... something!
14:13 GuShH http://www.distel.co.uk/step_motors_selection.htm
14:13 GuShH they mostly sell surplus
14:15 GuShH not good enough?
14:15 GuShH hard to please...
14:16 GuShH "Ch4 Man with 10 Stone Testicles" WTF
14:22 RifRaf GuShH, lol yes they are heavy things, thats why mine still is not here, need to get a couple of people to move it easy
14:32 KongfuPanda what is the name for motor heads?
14:32 KongfuPanda like the plastic things that go on the shaft
14:36 KongfuPanda sprocket
15:03 GuShH RifRaf: heh if I were nearby I'd give you a hand!
15:04 GuShH between the freight guy and I we could move it rather easily, even though the box has no handles whatsoever
15:05 GuShH KongfuPanda: sprocket... bike ones?
15:05 GuShH making it fit with the shaft will be the difficult part but you said you have access to a shop
15:05 GuShH I guess there's a lathe in there as well? :P
15:06 GuShH RifRaf: I can see what you mean about some things needing work on the lathe, there aren't even springs on the steadies
15:06 KongfuPanda GuShH, yeah, I need to put something on the stepper motor (6.35 mm or 1/4 inch shaft) so that it can yank the chain
15:06 GuShH KongfuPanda: try machining a delrin adapter
15:06 GuShH with a sort of face-plate end so you can screw the sprocket on
15:07 GuShH this is what I meant about the whole thing turning into madness.
15:08 GuShH one thing leads to the other and next thing you know you are mining for iron to cast your own old fashioned sprocket
15:09 GuShH hmm also the handle on the tailstock sucks, the pivoting portion... that needs replacement
15:09 GuShH oh I need to find out how many gears I'm supposed to get
15:09 GuShH I counted 6, one is rusty but was covered in oil.. go figure
15:11 GuShH and I can't find the chuck guard, maybe it was optional and they cheaped out
15:12 GuShH quick change toolpost and DRO are actual options they give you at the factory but nobody orders them
15:12 ShH s
15:26 GuShH all the crap they hand you in a crappy "toolbox" http://gushh.net/tmp/dscn3671f.jpg heh, cute attempt at a couple screwdrivers with wooden handles... why even bother...
15:27 GuShH almost everything removed to move it around more easily http://gushh.net/tmp/dscn3676f.jpg
15:28 GuShH cat wonders what's going on http://gushh.net/tmp/dscn3670f.jpg heh
15:33 GuShH Odd, it comes with a drag plate but no dog.
15:33 RifRaf all looks nice, i did however get a metal toolbox and old school metal oilcan with mine
15:33 GuShH you had the option?
15:33 RifRaf nope just what it had
15:34 GuShH heh that's interesting
15:34 GuShH they must be lowering costs even more
15:34 RifRaf toolbox is same colour as lathe
15:34 GuShH the 4 jaw chuck leaves a lot to be desired
15:35 RifRaf yeah don't use it much but does work once you get parts mounted correctly
15:35 GuShH the jaws seem to jump off their way / rail
15:35 GuShH looks like some of their drilling operations were taken over by a drunk angry chinese.
15:36 GuShH there was even some swarf in the toolbox and the box itself, how cute
15:36 GuShH at least it came with the swarf tray
15:36 GuShH I bet most of the specs on this piece of paper are a lie
15:36 GuShH everything is under half of their tolerance
15:37 GuShH or exactly half
16:42 KongfuPanda GuShH, I think I have identified all the components finally :)
16:43 KongfuPanda GuShH, wanna see which ones?
16:43 KongfuPanda it will cost ~200 dollars
16:54 rue_house of what?
17:01 KongfuPanda rue_house, I want to automate this kinda thingy: https://dl.dropboxusercontent.com/u/26776513/system.jpg , https://dl.dropboxusercontent.com/u/26776513/rail1.jpg
17:03 KongfuPanda rue_house, for this, I will get http://www.pc-control.co.uk/stepperbee_plus_info.htm , http://www.pc-control.co.uk/stepper_motor2.htm , a 3A, 12V PSU, a sprocket: http://www.technobotsonline.com/04b-steel-chain-sprocket-6mm-12t.html , a chain http://www.ptandbearings.co.uk/index.php/04b-1-6mm-roller-chain-04b-6mm-pitch-5-mtr-box.html and a pulley
17:04 KongfuPanda the controller has a dll library, which I should be able to import in matlab and add this automation to other things I already have automated
17:04 Rif bit brisk this morning, nice frost
17:05 Rif KongfuPanda now rue house will try make you do it all for less than $5
17:05 KongfuPanda :D
17:06 KongfuPanda Rif, I think I can only bring the price down if I buy used items. BUt because this is for work, I need to go the proper way
17:09 Rif yep watever works, if your budget can afford it then why not take the easy way i reckon
17:10 Rif that 7A stepper driver you are getting looks like it'll do the job well
17:10 KongfuPanda there is a 0.5A version, which will also do the job. But the price difference 33 vs 43 is not really worth . Better get the 7A one
17:16 KongfuPanda Rif, is that stepper motor good?
17:31 GuShH Rif: talk about morning frost... found a couple frozen / rotten oranges on the tree today :(
17:31 GuShH I should harvest them all and make jam while I can
17:32 GuShH the tangerines seem to cope a lot better with the cold
17:32 GuShH KongfuPanda: sounds expensive for all the labour involved :/
17:33 GuShH for the psu consider an ATX
17:33 GuShH cheap, powerful, protected... clean enough for this type of job
17:33 ShH is tired from moving lathe parts upst
17:33 GuShH I've yet to figure out if I can remove the motor from the lathe and some other parts like the entire carriage so I can actually lift the thing and bring it upstairs
17:34 GuShH otherwise I'll have to seriously reorganize the garage and find a spot for it... kinda hard with that stupid safe in there
17:34 KongfuPanda GuShH, I was thinking about this one: http://www.maplin.co.uk/dc-3-12v-3a-compact-bench-power-supply-96963
17:34 ShH sips a mi
17:34 GuShH but why not an ATX?
17:35 GuShH it doesn't have to look pretty or does it
17:35 GuShH thing with the ATX is you'll get extra rails for future expansion
17:35 GuShH say you need 5v suddenly or 3.3v, it's there already. albeit with some noise but you can filter it
17:36 KongfuPanda GuShH, well, it is a possibility, but looks ugly http://www.maplin.co.uk/300w-micro-atx-psu-221269
17:37 GuShH why does it have to look "cute" anyway
17:37 GuShH PSUs are square humming boxes that sit in a corner
17:37 GuShH also 20 pounds for that piece of crap is a ripoff
17:37 KongfuPanda ok, I'll get an ATX PSU
17:38 KongfuPanda yeah, maplin is a rip-off store
17:38 KongfuPanda but you can go in and buy what you want at least
17:38 GuShH I'm not trying to impose ideas, I'm just sharing from past experiences!
17:38 GuShH I wish we had a home improvement store or electronics store open 24/7
17:39 GuShH Some stores in the US are like that
17:39 ace4016 yes
17:39 KongfuPanda GuShH, which http://www.ebuyer.com/search?sort=price+ascending&cat=149&store=2&cat=149&page=1 ?
17:39 GuShH I'd be the weird guy buying random tools at 4AM
17:39 ace4016 lol
17:39 GuShH ...that would be amazing
17:39 ace4016 4AM is normal!
17:39 GuShH no crying babies no annoying people in general
17:39 ace4016 how else do you get all your stuff for the day?
17:39 GuShH now if there is a crying baby... I might consider murder.
17:39 ace4016 work starts at 8; got to get your supplies sooner than that :P
17:40 KongfuPanda ooo, I'll get a PSU with a LED
17:40 GuShH duct tape, check. big knife, check. wd40, check.
17:40 GuShH KongfuPanda: see if they've got spares at the uni
17:40 KongfuPanda OOO
17:40 GuShH everyone has spare ATX around
17:40 KongfuPanda they got tonnes
17:40 GuShH even I do...
17:40 GuShH so that's "free power"
17:40 KongfuPanda even PCs
17:41 KongfuPanda sometimes our IT man gives away old PC
17:41 GuShH learn the rue way.
17:41 KongfuPanda excellete
17:41 GuShH it's all zen and shit.
17:41 GuShH rue_house: how big is your shop?
17:42 GuShH why don't you have a youtube channel with weekly videos?
17:43 ShH stares at the fallen gib and wonders if he messed up some type of calibration now that he took the entire compound
17:45 rue_house 4.9822076e-31 square lightyears
17:46 GuShH ...
17:46 GuShH I didn't know lightyears was a measure of space
17:46 GuShH or volume for that matter :/
17:46 rue_house it is if they are square
17:46 theBear heh, and don't even get me started on parsecs
17:46 GuShH MATTER
17:46 theBear ANTI
17:47 theBear i mean it doesn't
17:47 GuShH we have a plumbers putty called parsecs!
17:47 theBear lol
17:47 GuShH it takes ages to dry.
17:47 theBear well, that's not much good then is it ?
17:47 rue_house my shop has a volume of 3.7010459e-48 cubic parsecs
17:47 theBear i only measure workshops in square lightyears, by squareroot miles
17:47 ShH slaps rue_house around with an empty miller
17:48 GuShH thanks for that theBear now my head hurts
17:48 theBear cos you know, square lightyears is one dimension short :)
17:48 rue_house what, did I goof a decimal place?
17:48 rue_house those numbers are accurate
17:48 theBear and the squareroot, that's just to be annoying
17:48 ShH shakes
17:48 theBear hehe
17:48 ShH shakes some more for good mea
17:48 GuShH problem is.. I'm out of beer now
17:48 theBear my workshop is 3/5 * 1/2* 6/13th chains
17:49 GuShH http://www.adhesivosparsecs.com/
17:49 rue_house fractions, thats evil
17:49 theBear i've just opened the last bottle of wine, and it turns out i DO have enough eggs, so ya know, it's on... ring a ding ding
17:49 GuShH oh they make sealers... I bet they suck.
17:49 theBear not to mention using a long dead unit rue
17:49 theBear and noncompatible fractions for a bonus
17:49 eBear is ON FIRE thismor
17:50 rue_house 1127m^3
17:50 GuShH Yeah that's how flammable you are
17:50 rue_house my lot is measured in chains
17:50 theBear seriously ?
17:50 GuShH Hmm I haven't even plugged in the lathe yet, because well.. it's in the box, but I should try it anyway
17:51 rue_house yea, iirc its like 2.5 long by 1/2 wide
17:51 GuShH they told me it was tested before it shipped out
17:51 GuShH but who knows
17:51 rue_house er, its 1 wide
17:51 rue_house 4.5 long
17:52 rue_house why cant dell tell me the exact parts in a machine, grrrr
17:52 GuShH Rif: you reckon the 4 jaw can be reversed?
17:52 rue_house it can
17:52 ShH thinks it should be doable in th
17:52 rue_house you have to use the alternate set to reverse the 3 jaw
17:53 GuShH no, I mentioned 4 jaw
17:53 GuShH independent one
17:53 GuShH yes I did get an extra set for the 3 jaw chuck
17:53 GuShH internal and external
17:53 GuShH but I wonder if the 4 jaw can't be flipped around
17:53 rue_house did you get a live centre?
17:53 GuShH no
17:53 rue_house the 4 jaw can be flipped
17:53 rue_house did you get a dial indicator with magnetic base?
17:53 GuShH it doesn't come with a jacobs chuck nor a live center
17:54 GuShH err these are things you buy after the lathe
17:54 rue_house yea, I had almost $1000 in extras
17:54 GuShH and I -just- got the lathe and it's still in the box, so no sir.
17:54 rue_house ah
17:54 rue_house it'll be out of alignment too
17:54 GuShH I'm going to call the tool guys tomorrow, I want my 17 tools already
17:54 rue_house oh, and they mark it in metric and imperial, ONE is wrong
17:54 GuShH you mean for between centers cutting? I bet
17:55 rue_house and its the imperial thats wrong
17:55 GuShH it'll probably turn a taper
17:55 rue_house they say .001" but its really .00098, cause the .025mm is accurate
17:55 GuShH but first things first, finding a place so the lathe can be setup.
17:55 rue_house I built a steel table
17:55 rue_house !assist lathe
17:55 GuShH I wanted the original cabinet,t hey don't carry it
17:56 rue_house http://eds.dyndns.org/~ircjunk/projects/lathe/
17:56 rue_house I used a 3000lb electric actualtor and a LOT of patience
17:56 GuShH for some reason the swarf tray on mine is blue
17:56 rue_house http://eds.dyndns.org/~ircjunk/projects/lathe/p1040773.jpg
17:57 rue_house I had the base of a hotpital bed to move it around on
17:57 rue_house up 2"/time/end
17:57 rue_house http://eds.dyndns.org/~ircjunk/projects/lathe/p1040776.jpg
17:57 GuShH heh
17:57 rue_house http://eds.dyndns.org/~ircjunk/projects/lathe/p1040777.jpg
17:58 rue_house I was really scared I'd roll it while transfering, I did it one end at a time
17:58 rue_house http://eds.dyndns.org/~ircjunk/projects/lathe/p1040793.jpg
17:58 GuShH If I can remove the entire carriage and the motor then I'm sure I can lift the rest just easily and bring it all upstairs
17:59 rue_house I should take pics of all the tools I'v made for it
17:59 GuShH what exactly is that? http://eds.dyndns.org/~ircjunk/projects/lathe/p1040793.jpg
18:00 rue_house see next / last image, its for making worm gears that fit threaded rod
18:00 GuShH and do you use turds instead of welding electrodes?
18:00 rue_house turd is cheaper
18:00 GuShH bah I don't have any pics of my welds online anymore
18:00 GuShH and if I were to take one now it would show pure rust, most of the stuff is outside
18:00 rue_house its stick, they are short
18:00 GuShH I do stick...
18:01 rue_house I was trying to kkeep it aligned when I did it too
18:01 rue_house I'll get tig going and all will be good
18:01 GuShH that's a bit harder as it tends to bend
18:01 GuShH or rather pull to the hottest side
18:01 rue_house I think that metal was something fancy too
18:02 GuShH all of these chinese lathes look so similar, the tailstocks the ways..
18:03 rue_house ytea, remember to chang the oil right away
18:03 rue_house they didn't flush them so good, lotsa bits
18:03 GuShH this one doesn't have a sump, what do you mean?
18:03 rue_house the gearbox
18:03 GuShH and sure about the packing oil... most has been removed
18:03 GuShH the gearbox is open air
18:03 GuShH yours has a speed change gearbox as well
18:04 rue_house you dont have the 2/3 speed select like I do?
18:04 GuShH mine doesn't, that model doesn't exist in Argentina
18:04 rue_house ah
18:04 rue_house they sell it in the usa as "grizzley"
18:04 GuShH not even the largest ones they sell
18:04 GuShH which cost over twice what I paid
18:04 rue_house how much was yours?
18:04 GuShH those do come with the cabinet heh
18:04 GuShH in the us it costs 1200 bucks I paid twice as much, which isn't uncommon here.
18:05 rue_house that fella there, all said and done, was about 4000
18:05 GuShH there's nothing I can do about it other than start shooting politicians
18:05 GuShH I bet once I get all the tooling and instruments it'll amount to something similar.
18:06 GuShH but for now all I need is a basic set of tools, I'll get the rest when I can.
18:06 rue_house I had to build my own parting tool holder cause they could NOT get the high quality one in stock
18:06 rue_house I'v already almost broken all the carbide tips I got
18:07 rue_house so I'm just using the hss I had
18:07 GuShH this is the set I ordered, but still haven't got a single word from the seller... http://img1.mlstatic.com/juego-de-herramientas-de-torno-metal-duro-17-piezas-cabo-58_MLA-O-2590224626_042012.jpg
18:07 rue_house .. but you only need straight, left and right
18:07 GuShH well that's the illustration for 5/8 size, but they're the same just smaller.
18:07 GuShH rue_house: actually I do want the extras
18:08 rue_house you got all carbide?
18:08 GuShH specially the ones like 115, 113
18:08 rue_house there is no lefthand bit in there....
18:08 rue_house er righthand, whatever
18:09 GuShH it's in spanish but oh well http://www.ditoma.net/ml/juego_jerramientas_soldadas_metal_duro.JPG
18:10 GuShH there are left and right bits
18:10 fishshock hello
18:10 GuShH hai
18:10 fishshock anyone thare?
18:10 GuShH no
18:10 rue_house will yours do left hand thread? mine wont
18:10 fishshock oh high
18:10 GuShH rue_house: why not? reverse and flip the tool
18:10 GuShH I thought that's all you needed to do
18:11 GuShH compound set to the opposite side
18:11 rue_house no, you need the feed to run the other way
18:11 fishshock anyone here a hacker?
18:11 GuShH but you start from the other side and run in reverse
18:11 GuShH fishshock: yeh we hax0r
18:11 rue_house the chuck and feed reverse at the same time
18:12 GuShH I could get some blank bits... but...
18:12 rue_house hss is cheap
18:13 GuShH (18% cobalt ones)
18:13 GuShH heh I don't have any plans for fancy tool holders and inserts
18:13 GuShH not right now at least
18:13 fishshock hey gun?
18:13 rue_house I didn't think I'd do borring, just make a borring bar last week
18:14 GuShH it's soooo boring
18:14 rue_house I'm playing with making engine sylinders
18:14 GuShH https://www.youtube.com/watch?v=FRa5An0i_sM
18:14 GuShH what size?
18:14 rue_house I got a brake hone
18:14 GuShH I want to make small model engines
18:14 rue_house 1"
18:14 GuShH specifically diesel ones
18:14 GuShH and if that fails, spark conversion heh
18:15 fishshock hey
18:15 rue_house GuShH, I have reason not to trust your youtube links :)
18:15 GuShH don't be silly
18:15 GuShH watch it
18:15 GuShH it's from mrpete.
18:15 fishshock anyone here a hacker?
18:15 GuShH about left hand thread.

18:16 GuShH "so your a hacker?"
18:16 fishshock well ask?

18:16 fishshock http://vigilantcitizen.com/hidden-knowledge/origins-and-techniques-of-monarch-mind-control/
18:16 rue_house 0x80085
18:16 GuShH would you print that for me?
18:16 fishshock i need a team
18:16 GuShH so I can wipe my arse with it
18:17 GuShH rue_house: he doesn't mention anything that would make it impossible with just about any lathe
18:17 fishshock shure but only if you see what i fight agenst\
18:17 GuShH fishshock: I think this isn't the right channel.
18:17 GuShH rue_house: oh he mentions feed reverse lever
18:17 GuShH is that what we're missing?
18:18 GuShH so it basically has another gear to invert the direction of rotation
18:18 rue_house yea
18:18 GuShH it's not like you need LH threads all the time though
18:18 rue_house I need to make a matching pitch gear, and use as an idler
18:19 GuShH bah I can't get the gib to fit without removing the set screws
23:37 MrCurious GuShH: did it arrive?
23:44 MrCurious ouchouchouch hot glue is .... HOT!
