[00:44:06] <XXCoder> I died twice
[02:50:03] <zhivko> HI guys!
[02:50:36] <zhivko> I have question regarding G64 P- <Q- > blending with tolerance.
[02:50:48] <zhivko> What are units for P and for Q ?
[02:51:24] <zhivko> Is it for P mm (basic length unit) and for Q - mm/min ?
[02:54:25] <XXCoder> hey
[02:54:32] <XXCoder> dunno answer just saying someones alive heh
[02:54:45] <XXCoder> this time is one of quietest periods for this channel
[02:57:17] <zhivko> oh
[05:01:26] <miss0r> DaViruz: You around? I can't seem to find the page you linked me to yesterday, with the small surface grinder for sale
[05:02:09] <archivist> I thought he was going to get that one
[05:02:45] <miss0r> if he was, I won't get it. I just thought I remembered him saying he didn't have the room for it, or something like that
[05:03:26] <archivist> https://www.blocket.se/dalarna/Planslip_70192095.htm?ca=9&w=3
[05:03:34] <miss0r> Thanks :)
[05:03:46] <archivist> my log http://emclog.archivist.info/
[05:03:59] <miss0r> Good thing to keep :)
[05:05:19] <archivist> confusing statements, one he quite likes, then dont know how he can fit it in
[05:05:31] <archivist> I know the problem
[05:06:43] <miss0r> i'll need to speak with him later tonight. If he is not going to buy it I will. I made a few phone calls earlier about my Jacobsen SJ-16 surface grinder. I got a bid right away. apparently theres someone in India buying up alot of the old jacobsen grinders. He offered ~$2k off the bat
[05:07:48] <miss0r> archivist: as I don't have alot of experience with surface grinders, and you seem to do. Does this unit look worth my while? or acurate surfaces?
[05:08:14] <zhivko> hello guys!
[05:08:21] <miss0r> o/
[05:08:22] <zhivko> archivist: do you know maybe:
[05:08:25] <zhivko> I have question regarding G64 P- <Q- > blending with tolerance.
[05:08:25] <zhivko> What are units for P and for Q ?
[05:08:32] <archivist> its better than what I have
[05:08:44] <archivist> zhivko, the manual does say
[05:08:51] <zhivko> Only for P
[05:09:43] <zhivko> " feed rate that are less than Q- away from being collinear"
[05:09:51] <zhivko> how can feed rates be colinear ?
[05:10:41] <zhivko> I've heard to lines to be colinear but not two feedrates - what is corect interpretation of this - maybe somebody knows ?
[05:10:50] <zhivko> "two lines"
[05:10:55] <archivist> lines are colinear
[05:11:23] <archivist> imagine two lines almost in a line
[05:11:35] <zhivko> I am ok with 2 lines beeing colinear
[05:11:39] <zhivko> I understand this
[05:11:55] <zhivko> BUT: "feed rate that are less than Q- away from being collinear"
[05:11:58] <archivist> so close that one line will do
[05:12:11] <archivist> no need to slow
[05:12:13] <zhivko> Oh - so this is interpreted like speed as a vector ?
[05:13:02] <zhivko> feedrate = speed = vector?
[05:13:46] <archivist> no, think about slowing to turn corners, less corner less slowing
[05:14:14] <zhivko> but this is done with P or not?
[05:14:22] <zhivko> I have difficulties understanding Q
[05:15:26] <archivist> reading the docs means it is swapping which trajectory plan depending on p and q
[05:16:45] <archivist> miss0r, that one seems a reasonable compromise between massive and too small
[05:17:56] <zhivko> what are units of Q ?
[05:17:59] <zhivko> mm ?
[05:18:03] <miss0r> glad to hear you say so. I'll probally need to scrape in the ways before putting it to use. unless it turns out its hardly ever used :)
[05:21:25] <archivist> over here a local maker http://www.ebay.co.uk/itm/Jones-Shipman-540-surface-grinder-with-articulated-lamp-spares-or-repair-/332026510637
[05:23:17] <archivist> hmm better one http://www.ebay.co.uk/itm/Jones-and-Shipman-Surface-Grinder/192023952303
[05:24:03] <miss0r> atleast cheaper. Thoes both seems too big :)
[05:24:22] <miss0r> The first one could do with a lick of paint :]
[05:25:12] <miss0r> Thoes are both hydraulic. while that is nice, I can certainly do with a manual for what i'm doing
[05:25:30] <archivist> second claims tatty but what you can see looks ok, only 30miles from here....auction ends before my retirement cheque will arrive
[05:26:37] <miss0r> that and you need to eat.
[05:27:46] <XXCoder> arch you retiring or already retired?
[05:30:06] <archivist> had no sensible work for ages, and found out I can retire a bit early, just waiting on the post for a form to sign and return
[05:30:41] <archivist> only 8 months early
[05:31:14] <XXCoder> interesting
[05:31:23] <XXCoder> im likely to die
[05:31:26] <XXCoder> working
[05:31:36] <XXCoder> sorry hit return too early lol
[05:31:44] <XXCoder> anyway I finally got good working job at 39
[05:32:03] <XXCoder> which is way too flipping late to save up good retirement money,
[05:32:18] <miss0r> For reasons unknown to me, I was under the impression that you were perhaps 40, archivist. :)
[05:32:37] <archivist> nope, old free and single
[05:32:59] <XXCoder> middle age, free and single :P
[05:33:04] <miss0r> I remember being young, free and single :)
[05:33:20] <miss0r> now I guess i'm just young. i'm 29
[05:33:40] <zhivko> they say time is relative :)
[05:34:00] <miss0r> who are 'they'... let me at em!
[05:37:25] <Valen> 30 married 3 dogs does that count?
[05:39:49] <miss0r> as your youth being gone? no, you need kids for the last of your freedom to be gone.
[05:40:43] <miss0r> i'm thinking freedom consumption of 3 dogs <= 1/13 of a toddler.
[05:43:39] <zhivko> miss0r: but kids make you young - haven't you noticed that ?
[05:44:06] <miss0r> no I have not
[05:45:11] <Deejay> moin
[05:45:28] <miss0r> mornin'
[05:50:20] <Tom_L> hey
[06:00:46] <jthornton> morning
[06:00:50] <XXCoder> yo
[06:11:57] <gonzo_> kids make you age
[06:13:03] <gonzo_> and the worst moment is, when you use a phrase with them (usually telling off) and cringe as you realise that it was what your parenets said to you
[09:30:29] <jdh> like 'hold my beer and watch this'?
[09:32:28] <MacGalempsy> morning
[09:33:26] <MacGalempsy> a new cnc project sight.
[09:33:35] <MacGalempsy> http://academy.titansofcnc.com/
[09:36:46] <gregcnc> see anything good there?
[09:39:31] <MacGalempsy> just started browsing. looks like it may have all the stuff to machine an autodesk Ember
[09:40:02] <MacGalempsy> the files dont seem to describe each part. just files
[09:41:35] <MacGalempsy> nm. i found descriptions. looks like training and practice stuff
[09:43:06] <gregcnc> that's what I was expecting. I signed up but missed the announcement in a disposable email address
[09:43:09] <miss0r> DaViruz: why are you not around yet?!
[09:45:21] <miss0r> XXCoder: why haven't you found the correct spindle yet? Anything I can do to help?
[09:46:27] <MacGalempsy> gregcnc: i expect it to get better because its backed by autodesk
[09:51:39] <MacGalempsy> well. like the 1st 10 things have descriptions
[10:37:43] <gregcnc> 3D printed tooling anyone? https://www.youtube.com/watch?v=eljV1wzFGAs
[10:41:00] <Jymmm> lol, Using "3D Printed" as a marketing buzz word
[10:41:34] <gregcnc> I wonder what they cost
[10:41:50] <Jymmm> "But but but it's 3D printed toilet paper!!!"
[10:42:32] <Jymmm> Sorry, I meant "Butt butt butt it's 3D printed toilet paper!!!"
[10:42:52] <archivist> gregcnc, notable missing item from vid, actual cutting
[10:42:58] <gregcnc> yeah
[10:43:22] <gregcnc> they make aluminum face milling holders so i'm sure it cuts
[10:43:22] <Jymmm> or actual photo of said product
[10:43:23] <archivist> and they repeated themselves to pad it out a bit
[10:43:41] <gregcnc> sounds like custom tooling to me
[10:44:11] <archivist> or fishing for first customer to try it out
[10:47:08] <MacGalempsy> laser melting!
[10:47:30] <DaViruz> miss0r: i am now!
[10:48:13] <MacGalempsy> the way the video looks, the machine fires molten metal from the hotend
[10:48:26] <DaViruz> archivist: regarding worm gear precision measuring? yes i did, sorry, it was quite interesting
[10:50:33] <archivist> DaViruz, I never wrote up the optical method I did though
[10:50:50] <DaViruz> optical?
[10:51:24] <archivist> angle dekkor (a type of autocollimator) and precision polygon
[10:52:20] <archivist> amateur telescope makers also know of the worm tooth error rate
[10:57:32] <DaViruz> i wonder how a harmonic drive reduction compares?
[10:58:59] <archivist> never seen one cheap enough for me to try :)
[10:59:55] <archivist> some seem to quote nice accuracies
[10:59:59] <sync> they are often quite cheap on ebay
[11:00:20] <sync> and they are easy to demount when stuck
[11:00:35] <sync> you can just put a pipewrench on them and break the coupler
[11:00:41] <archivist> define cheap, some of us not got sensible earnings
[11:01:12] <gregcnc> compared to new cost
[11:03:03] <archivist> £300 is not cheap for me
[11:03:08] <gregcnc> i've seen harmonic drives for 100USD
[11:03:58] <archivist> I bet they chuck them when their hours are near the fatigue fail point
[11:04:23] <sync> nah
[11:04:49] <sync> but for £300 you can always get some
[11:04:56] <archivist> a cheap new one NOT http://www.ebay.co.uk/itm/CNC-3-Jaw-100MM-Chuck-4th-Axis-Harmonic-Drive-Router-A-axis-Rotational-Ratio-3-1-/161683122064
[11:04:59] <sync> occasionally they pop up a lot cheaper
[11:05:22] <sync> that one is pretty cheap archivist
[11:05:33] <sync> and works quite well, someone on the forums here got one
[11:06:18] <DaViruz> we hade a few at my previous work, we replaced one which i considered taking home, but it had developed a quite nasty backlash
[11:06:32] <DaViruz> and it was huge
[11:11:20] <FinboySlick> archivist: While you're awake, I might need your historical knowledge.
[11:12:27] <archivist> and...
[11:12:28] <FinboySlick> archivist: Ever heard of lathes labeled 'billybee' (or some other similar spelling) It would be pretty old.
[11:12:37] <archivist> no
[11:12:56] <archivist> does not sound english at all
[11:13:09] <archivist> americam maybe
[11:14:19] <archivist> busy bee tools, canadian
[11:14:30] <FinboySlick> Yeah, but I don't think they existed back then.
[11:15:01] <sync> archivist: I have tried to measure my worm gear rotary, it seems like their 12" claim is right and I cannot really make out cyclic errors
[11:17:11] <archivist> some worm dividing heads are made well, but not all
[11:19:14] <archivist> FinboySlick, there is a mailing list for old tools mainly american and woodworking oldtools also a website collecting american tool patents datamp
[11:20:17] <FinboySlick> archivist: I'll be able to get more information in a little while, I was just wondering if it rung a bell.
[11:20:19] <archivist> https://swingleydev.com/archive/faq.html http://www.datamp.org/
[11:20:40] <archivist> not at the moment
[11:21:15] <FinboySlick> archivist: An old uncle wants to get rid of it and apparently it is quite a chunk of iron. I'm wondering if it's worth looking into.
[11:21:33] <archivist> and unknown here http://www.lathes.co.uk/page21.html
[11:22:17] <archivist> from the name it sounds like a retail name/bought in from some other maker
[11:23:06] <FinboySlick> Yeah, that's what I thought too. I'm wondering if I'll get lucky or if it's a piece of junk.
[11:23:44] <archivist> if price is right, go for it :)
[11:24:12] <FinboySlick> Oh it's free... Except for going to get it and finding a place to store it.
[11:25:27] <archivist> I have wrapped stuff in the garden for a "while" then bought in and restored
[11:26:51] <archivist> even unwrapped cast iron survives quite well
[11:27:42] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=filing+new
[11:42:37] <SpeedEvil> cast iron is most excellent in the rain
[11:42:42] <SpeedEvil> steel not so much
[11:43:12] <Jymmm> SpeedEvil: for rusting?
[11:43:15] <SpeedEvil> steel -> 5mm eroded shaft, into a cast iron pulley with light surface rust and pitting.
[12:29:05] <IchGucksLive> hi
[12:29:36] <IchGucksLive> cold outside a giant moon
[12:37:05] <IchGucksLive> -3deg C now just went to see the moon but its to cold
[12:38:22] <SpeedEvil> layers
[12:40:20] <IchGucksLive> not worth to be its cloudy and foggy
[12:40:36] <IchGucksLive> so its 40years to wait
[12:40:44] <IchGucksLive> not gone make it till
[12:44:08] <Cromaglious_> sheeeshz... NZ got yet another 5.8 aftershock
[12:44:09] <SpeedEvil> The supermoon is a deeply hyped unimpressive event.
[12:44:28] <SpeedEvil> It is meaninglessly less bright a few times a year
[12:45:03] <SpeedEvil> And it is not actually bright enough that if you did not know it was a supermoon you would be able to reliably tell
[12:46:34] <Cromaglious_> a super moon came during a performance of Complete Works of Wm Shakespeare (abridged) and out actor said the line from ROmeo and Juliet except added Super
[12:46:44] <IchGucksLive> Oh outside the town in Darknes the moon is mutch greater
[12:47:02] <Cromaglious_> s/out/our/
[12:47:32] <IchGucksLive> your eys are triggy on light emission
[12:47:58] <MrSunshine> hmm how the hell to measure parallellism 1.5 meters apart ...
[12:48:06] <IchGucksLive> so with whide open Pupillas it gets other view
[12:48:12] <Cromaglious_> brought quite the large laugh... our stage was in the parking lot of a winery so every one had a very good view of the super moon
[12:49:11] <Cromaglious_> MrSunshine, 2 framing squares and a straight edge?
[12:50:06] <djdelorie> MrSunshine: water level?
[12:50:27] <djdelorie> (at least for parallelizm perpendicular to gravity)
[13:05:12] <Leo__> hello! Anyone here that can help me how to establish a servo control loop using mesa 7i77?
[13:05:30] <JT-Shop> don't ask to ask just ask the question
[13:05:38] <Leo__> ok ty:)
[13:06:14] <Leo__> I have 6i25+7i77 (analog servo control); my servo drives are analog Bosch SM
[13:06:37] <Leo__> the encoders of servo motors are connected to the servo drives
[13:06:47] <Leo__> the servo drives dont have encoder outputs
[13:07:07] <Leo__> As I can see the servo drives have an internal PI control
[13:08:07] <Leo__> Do I leav them be or do I share the encoder outputs? Or maybe set up a dual loop: servo encoders in servo drives AND axis encoders in linuxcnc
[13:08:22] <JT-Shop> most drives have PID for the drive and the ENCY card is a Y adapter for encoders
[13:08:29] <JT-Shop> http://mesaus.com/index.php?route=product/product&path=65&product_id=101
[13:09:12] <Leo__> yes the servo encoders have A, B and C(index) outputs
[13:10:00] <Leo__> Do I need the Y connection? Or can I only use the axis encoders to drive the servos?
[13:11:37] <MrSunshine> Cromaglious_: two rails 1.5 meters apart
[13:11:39] <JT-Shop> AFAIK if the drive does not pass the encoder signal through then to get it to LinuxCNC you use the Y adapter... someone smarter than me may pass by later
[13:12:17] <Leo__> If I disconnect the encoder signals to the drive and only use them in linuxCNC?
[13:15:12] <Leo__> If I use the Y connection, what about the internal PI loop that the servo drives have? Would it not interfere with the new linuxcnc PID loop?
[13:22:45] <nubcake> hi
[13:23:04] <IchGucksLive> cool
[13:33:30] <JT-Shop> Leo__: the controller will adjust the output to get the position it wants and the drives adjust the direction and speed to get what the input is telling it to do
[13:34:43] <JT-Shop> my simplistic understanding of the drive pid loop is so the drive and spin the motor as fast as commanded or something like that
[13:41:26] <Leo__> ok
[13:45:33] <Leo__> I m doing a retrofit. An industrial cnc mill from the 1994. pretty powerful, the X and Y servos are 2kW
[13:46:25] <Leo__> I think that those industrial CNC machines have a dual loop set up. The inner loop is between the servo motor and the servo drive. The outer loop is between the axis encoder and the controller(linuxcnc)
[13:47:23] <Leo__> If I set up a dual loop system do I even need the servo encoders connected to the 7i77?
[13:49:52] <DaViruz> axis encoders as in linear encoders?
[13:50:46] <Leo__> yes
[14:21:07] <Jymmm> It's surprising on how fast molten salt cools down
[14:23:52] <Deejay> why do you melt salt?
[14:24:03] <Deejay> too much free time? ;)
[14:30:05] <gregcnc> how much did you melt?
[14:30:17] <Jymmm> Deejay: To see how it reacts as a thermal mass and ti test perlite as a high temp thermal insulator
[14:30:48] <Deejay> hm k
[14:31:12] <Tom_L> Jymmm just likes to play with fire
[14:31:21] <Jymmm> Deejay: http://www.sciencedirect.com/science/article/pii/S0360544216304546
[14:32:03] <Jymmm> Tom_L: that too
[14:32:47] <Jymmm> Plus I've never seen molten salt or if it can be done using just a propane torch. It sorta can but take a LONG LONG time
[14:33:11] <Tom_L> add a bit of oxy, that will speed up the process
[14:33:36] <Jymmm> no ixy available
[14:37:46] <CaptHindsight> what's the energy density of hot wind bags?
[14:39:28] <Tom_L> don't talk about old ladies that way
[14:41:02] <miss0r> You know the feeling, when you tear down a lathe gearbox, trying to fix the cludge, only to find there doesn't seem to be anything wrong with it ? :S
[14:46:39] <miss0r> this sounds like a job for.... tomorrow. goodnight
[16:34:01] <Deejay> gn8
[16:55:57] <nubcake> n8 everyone
[18:09:39] <JT-Shop> I think it will take me a month to get everything sorted out on this new desktop PC
[18:20:17] <Tom_itx> what did you get?
[18:25:26] <JT-Shop> I went and got the PC from the partnership, pretty fast what ever it is
[18:26:11] <Tom_itx> i seldom upgrade but did recently swap motherboards
[18:26:17] <Tom_itx> and added ssd
[18:26:52] <JT-Shop> it had a ssd but I think it crapped out so I put another hd in
[18:27:20] <JT-Shop> my windoze pc in the beer cave crapped out so I moved the slow one from the shop down there and fetched the other one
[18:27:27] <Tom_itx> i've been happy with samsung evo so far
[18:27:42] * JT-Shop turns his hat around to the chef side
[18:27:49] <Tom_itx> 1tb nd 2-3 500g
[18:27:50] <JT-Shop> see you in the am
[18:27:58] <Tom_itx> happy trails
[19:30:27] * dioz yawns
[19:32:08] <malcom2073_> First sign of zinc fever, yawning.
[19:32:11] <malcom2073_> ;)
[19:36:09] <Wolf_> lol
[19:41:28] <Tom_itx> hah
[19:43:45] <Wolf_> I hope no one here was bidding on levels on eBay about 4 hrs ago, if so.. sorry :P
[19:47:47] <Wolf_> http://www.ebay.com/itm/98-12-Starret-Machinist-Level-/152314688705 looking at auction feed back must have been a billiards shop, they had 4 listed at once with end times about 2min apart
[21:59:01] <BeachBumPete> Interesting hiw
[21:59:58] <BeachBumPete> How when I put the Z axis motor on the machine getting to the allen bolts was a real bitch and it was pretty much the same this time around too ;)
[22:00:43] <BeachBumPete> I mean getting to the allen bolts that secure the coupler to the ballscrew
[22:11:05] <jesseg> hey guys, I've been offered an Atrump knee mill with acme lead screws for $1800
[22:11:25] <jesseg> with a slide DRO on it, but not CNC
[22:11:39] <jesseg> Anyone had experience with older Atrump stuff?
[22:36:51] <CaptHindsight> http://www.centroidcnc.com/oems/atrump/atrump_cnc_kneemills.html bridgeport clone
[22:37:36] <CaptHindsight> what it's worth is up to you and what shape it's in
[22:38:14] <tiwake> trump milling machines
[22:38:18] <tiwake> oh gosh I want one
[22:38:29] <tiwake> make guns with them
[22:38:46] <tiwake> or whatever
[22:40:34] <jesseg> CaptHindsight, well, there is also the aspect of if it's a reasonable quality tool or total junk from overseas with poor parallel geometry and springy construction
[22:40:48] <jesseg> I mean I know it's from China
[22:40:56] <jesseg> but the company is still around I guess
[22:41:06] <jesseg> I don't know if they make parts for older ones
[22:41:40] <jesseg> this one's not CNC, just DRO/ACME
[22:42:16] <jesseg> K2V-777
[22:42:32] <CaptHindsight> http://atrumpparts.com
[22:42:38] <jesseg> Oh, I guess 777 is the serial. K2V is the model
[22:43:27] <MacGalempsy> hey everyone :)
[22:43:35] <jesseg> Howdy MacGalempsy !
[22:46:53] <jesseg> CaptHindsight, fascinating. Probably I oughta try to figure out how I'd get it home LOL..
[22:47:13] <jesseg> But they list 500 parts for that series of mills
[22:47:17] <jesseg> so I guess I can get parts
[22:49:43] <MacGalempsy> CaptHindsight: make anything cool today?
[22:51:29] <CaptHindsight> just a mess...cutting, bending, welding, grinding
[22:53:06] <CaptHindsight> along with vacuuming, sweeping, moping
[22:53:27] <jesseg> so how does one get a knee mill into their home? LOL Might have to take off the table and tip the thing backwards, then it might go through a man door.. I do have concrete floor, but no garage door.
[22:54:17] <tiwake> jesseg: if you drive it in fast enough you don't need a door
[22:54:36] <jesseg> tiwake, LOL.... battering ram... yes..
[22:55:05] <CaptHindsight> I once pickup a knee mill from an old machinist. He was ~80 (age and weight in lbs) and he moved it out to the driveway by himself using some rollers and a long bar
[22:55:22] <tiwake> sounds about right
[22:56:15] <jesseg> CaptHindsight, actually that is a fascinating idea.. I can get a bunch of chunks of pipe and use them as rollers. I can roll it up to the threshold of the mandoor, and start moving pipes to other side of threshold and just roll it in.
[22:56:17] <CaptHindsight> was a Cincinnati, I should have saved it
[22:56:24] <tiwake> probably had a shotgun that he used to threaten people with as they walked by
[22:57:33] <jesseg> maybe he just had shotgun shells stuck in the end of each pipe, and if someone came by he'd just reach down with a pointy hammer and hit the primer
[22:58:07] <tiwake> in the butt of his cane
[22:58:18] <CaptHindsight> he showed me some deer he hunted with a crossbow
[22:58:33] <jesseg> lol
[22:58:44] <tiwake> CaptHindsight: if he did that in midevil europe when crossbows were banned...
[22:59:12] <tiwake> yeah, total badass
[23:00:49] <CaptHindsight> was in medieval Wisconsin
[23:01:28] <tiwake> almost the same thing
[23:01:59] <CaptHindsight> where culture is always on vacation
[23:06:01] <Jymmm> CaptHindsight: It's in the cheese don't ya know
[23:06:44] <tiwake> not very good cheese
[23:10:01] <tiwake> well, I should get to bed
[23:27:23] <Wolf_> big bar and pipes is how I plan to partly move my pending purchase of 3 heavy machines
[23:27:38] <jesseg> Wolf_, what's the big pipe for?
[23:27:45] <jesseg> err big bar?
[23:27:46] <Wolf_> least to get them to the basement doorway
[23:27:50] <Wolf_> lever
[23:28:04] <jesseg> oh to jack it up bit by bit around
[23:28:17] <Wolf_> yeah, and to turn the machines
[23:29:55] <Wolf_> then like magic get it on the back of the truck and home
[23:30:04] <jesseg> I wonder if a tommy lift gate can lift this thing
[23:30:23] <Wolf_> doubtful
[23:30:27] <jesseg> yeah...
[23:31:09] <Wolf_> my real lift gate maxes out at 2000 I think
[23:31:30] <jesseg> hmmmm.. a friend has a tilting car hauler trailer, steel deck.
[23:31:48] <jesseg> I bet I could get seller to drive the mill on a pallet onto the trailer with forklift
[23:31:54] <jesseg> then I could roll it off the trailer
[23:31:58] <Wolf_> yup
[23:32:33] <Wolf_> I plan to lag the machines to 4x4” wood runners and pull them on to a custom hook truck sub-frame
[23:34:13] <jesseg> What is a hook truck sub-frame?
[23:34:55] <jesseg> Hmm, looking at you tube videos, it looks like the defacto way is to rotate the head 180 degrees to lower the height enough to get it through a man sized door
[23:35:16] <Wolf_> yup
[23:35:59] * Wolf_ looks for the pic that explains the truck
[23:38:49] <Wolf_> http://i.imgur.com/UM3Rf8L.jpg
[23:38:55] <Wolf_> kinda
[23:40:46] <Wolf_> great for moving things http://i.imgur.com/yERX7l3.jpg
[23:41:11] <jesseg> oh, does the whole bed slide down?
[23:41:49] <Wolf_> more then slides http://i.imgur.com/n05yPB7.jpg
[23:42:05] <Wolf_> usually used for small dumpsters
[23:45:31] <jesseg> AHHHH OK so you put bed on ground, drive in whatever you want, then it gets pulled up onto truck
[23:45:57] <Wolf_> yup, or have different beds for different jobs
[23:47:33] <Wolf_> I need to make a few more for my truck… been slacking on that because the dump bed worked for most everything
[23:48:22] <Wolf_> except that its now half rusted out and got somewhat messed up from a large stump being pushed off a hill in to it lol
[23:48:33] <jesseg> lol
[23:50:02] <Wolf_> not much to it though, http://i.imgur.com/wSkwsNi.jpg just 2 runners with a A frame at the front with a bar for the hook to grab
