04:10 AM Bing[m]: morning fellow freedom lovers
04:57 AM JT-Cave: morning
05:04 AM Mehdidadash[m]: good morning
05:04 AM Mehdidadash[m]: what does this mean ?
05:41 AM travis_farmer[m]: what does what mean?
05:49 AM TurBoss[m]: morning
05:58 AM JT-Cave: yo
06:34 AM JT-Cave: 33°F
06:43 AM Tom_L: 36°F
07:14 AM * travis_farmer[m] enjoys a drink from his childhood, sherbet punch (ginger-ale and sherbet) :-)
07:20 AM skunkworks[m]: what gives me warm fuzzies is kool aid hawaiian punch and 7-up.. Reminds me of parties and family get togethers..
07:36 AM mrec: does anyone have solidworks here and could convert some files to step for me?
07:37 AM mrec: https://grabcad.com/library/lm2596-dc-to-dc-buck-converter-module-1/details?folder_id=9422675
07:37 AM mrec: I need that one here
07:39 AM JT-Cave: I have SW but they don't say what version it is and SW won't open a file that is from a newer version
07:41 AM rmu: https://grabcad.com/library/lm2596-module-for-kicad-1
07:44 AM mrec: rmu: that fits I just checked it thanks
09:51 AM unterhausen: is there a way to extract oil from an engine through the dipstick port that doesn't cost a lot of money?
09:52 AM notmyproblem[m]: but why? get a cheap wrench and pull the plug
09:52 AM notmyproblem[m]: inb4 the plug is fugged
09:54 AM jpa-: unterhausen: i have seen small pumps marketed for that purpose, to make oil changes easier - i'm not enough of a mechanic to say if the dipstick port generally goes low enough to effectively drain all oil
09:54 AM unterhausen: someone overfilled the engine and I don't really want to get underneath to take out a small amount of oil
09:55 AM unterhausen: some people change the oil that way, and there are relatively expensive extractors for that purpose
09:55 AM jpa-: if you like motor oil in your mouth, you can always siphon it out :)
09:55 AM unterhausen: I asked the internet and found that there are syringe kits to do it
09:56 AM unterhausen: I think I have some relatively large syringes
09:56 AM unterhausen: It's that fancy european oil that volkswagon specifies, so it better taste like fine cheese
09:57 AM ZincBoy[CAON][m]: I change the oil in my cars through the dipstick using a mityvac unit. Works great but probably more than you want to spend for a one off.
09:58 AM unterhausen: that's a bit too much for now, but they aren't as much as I thought
09:58 AM roycroft: he just wants to suck a little of the oil out, not completely remove it
09:59 AM roycroft: the syringe and a hose will probably work fine
10:07 AM notmyproblem[m]: Ive had to do it once, I just pulled the plug, you get some on your hands but there's soap that exists and cleans it right off
11:33 AM aol: hallo robert,
11:33 AM aol: kann ich dir hier meine tel. nummer schicken oder sieht das jeder hier im chat?
11:43 AM JT[m]: I wonder if anyone has got the bandsaw off the pallet while I wait for the Insight service
11:50 AM bjorkintosh: unterhausen[m], harbor freight sells a hand pump.
11:50 AM roycroft: are you going to put the bandsaw n a mobile base?
11:50 AM bjorkintosh: very cheap, very convenient.
11:50 AM JT[m]: I want to put on a mobile base
11:50 AM bjorkintosh: https://www.harborfreight.com/multi-use-transfer-pump-63144.html
11:51 AM bjorkintosh: if you want to get fancy, they have ... https://www.harborfreight.com/gear-oil-and-fluid-pump-63588.html for 9.99. just 3 dollars more.
11:51 AM bjorkintosh: i figure since it's cheap plastic, they can't harbor freight can't possibly make it any worse than any one else.
11:53 AM JT[m]: If I'm not too tired when I get home I'll finish up the bandsaw
11:59 AM JT[m]: Raycroft do you have any photos of the base you built
11:59 AM roycroft: maybe
11:59 AM roycroft: but mine would not work for you
12:00 PM roycroft: my saw came on a stand, which i never installed
12:00 PM roycroft: instead i built a base cabinet
12:00 PM roycroft: i needed to lower the saw a wee bit for clearance, and i also wanted some blade/supplies storage
12:00 PM roycroft: give me a few - i might have something else that would be helpful
12:00 PM JT[m]: Ok
12:00 PM JT[m]: I do need to build a cabinet for blades
12:01 PM JT[m]: Ok
12:01 PM roycroft: i'm working on an os install right now
12:01 PM roycroft: i need to get it to the point where it starts scribbling files, then i'll have a little time
12:02 PM JT[m]: Ok no rush
12:05 PM roycroft: you're kind of tall, aren't you?
12:07 PM JT[m]: I'm shrinking lol 5 8.5
12:07 PM roycroft: ok
12:08 PM roycroft: the reason i asked is because i'm not sure if you want to raise the height of the table or not
12:08 PM roycroft: i actually lowered mine on the band saw
12:08 PM roycroft: i'm not tall
12:08 PM roycroft: and i wanted to be able to resaw long boards easily
12:08 PM roycroft: lowering the table a couple inches was perfect for me
12:08 PM JT[m]: No, I don't want to make it any higher
12:09 PM roycroft: so my mobile base designs that raise the machine won't work
12:09 PM JT[m]: Ok
12:11 PM roycroft: for my drill press i installed outboard pads so i could let the drill press sit low
12:11 PM roycroft: time to push some more buttons
12:11 PM roycroft: bbiab
12:12 PM JT[m]: Ok
12:31 PM unterhaus_: I have my bandsaw on one of those "build your own" bases from delta
12:33 PM roycroft: i had one of those on my old router
12:33 PM roycroft: that's probably the easiest way to add a low-profile mobile base
12:34 PM roycroft: my only concern would be that the delta is a three wheel base
12:34 PM unterhaus_: yeah, I wish it had two retractable wheels
12:34 PM roycroft: and the logical place to orient the retractable wheel is on the right side of the saw, but if it's there it may interfere with the foot brake
12:35 PM roycroft: it could be mounted on the left side, but that might make moving the saw around a bit more awkward
12:35 PM unterhaus_: too poor to have a brake here
12:35 PM roycroft: i like the three wheel design
12:35 PM roycroft: just in this case it could be an issue with the foot brake
12:36 PM unterhaus_: it's a bit tippy when moving, the good news is I only have a 16" bandsaw so I can just catch it
12:36 PM roycroft: if you're about, jt, this is what we're talking about: https://www.homedepot.com/p/Delta-Universal-Mobile-Base-50-345/203293655
12:37 PM unterhaus_: I heard the bora is a lot nicer, and I'm not sure if it's $240 nicer
12:37 PM roycroft: if you use a good, strong hardwood like ash for the 2x2s it would work great for that saw
12:38 PM unterhaus_: oak
12:38 PM roycroft: oak would work too
12:38 PM unterhaus_: I think it's mostly just the small distances involved
12:38 PM travis_farmer[m]: bird's-eye maple ;-)
12:39 PM unterhaus_: fresh out of birds-eye, got some nice looking curly maple though
12:40 PM travis_farmer[m]: maple is my favorite wood :-)
12:40 PM unterhaus_: I have some soft curly maple for guitars that is really nice
12:40 PM JT[m]: That one looks a bit weak
12:40 PM unterhaus_: hard curly maple is for a person of more refined taste
12:41 PM unterhaus_: all the universal bases look weak to me
12:41 PM travis_farmer[m]: rock-maple is the best for guitar, just because it has "rock" in it ;-)
12:42 PM unterhaus_: I always wanted to weld up some 2x2" steel for my bases, but I don't have a welder that will work on that
12:42 PM JT[m]: The shop fox I have on the disk sander seems well made
12:47 PM unterhaus_: the shop fox hybrid saw has some feet built in that would be nice to get seperately
12:48 PM roycroft: mine worked out well with my 6" jointer
12:48 PM roycroft: but normally i build mine out of angle iron
12:49 PM roycroft: i can't find my plans for my drill press one
12:49 PM JT[m]: I hate when that happens
12:50 PM unterhaus_: I even had the delta base under my DJ20 8" jointer and it worked
12:50 PM unterhaus_: but then amazon had the delta base for the DJ20 on sale for $60 so I bought one as quickly as I could before they came to their right minds
12:51 PM unterhaus_: the kit isn't rated for 500 pounds
12:51 PM JT[m]: The main concern for me is how tall and top heavy the pm1500 is
12:52 PM roycroft: yes, and if you have the floor space to spare, i would build the mobile base to extend the casters outboard a bit for better stability
12:52 PM unterhaus_: I don't want to oversell the kit, if I was buying I would probably buy a shop fox
12:52 PM JT[m]: The pm1500 is 400 pounds so you have to use a multiplier to get the actual capacity lol
12:55 PM unterhaus_: I would like to have something removable. Just seems like mobile bases get in the way of a bandsaw
12:55 PM unterhaus_: and if they don't, they are tippy
12:56 PM unterhaus_: The mobility kit laguna sold for my saw was expensive and looked tippy
12:56 PM roycroft: https://roycroft.us/EdgeSander/EdgeSander2.jpeg
12:56 PM roycroft: that machine weighs about 250lbs
12:56 PM roycroft: the mobile base was made out of 1"x0.120" tubing
12:57 PM roycroft: and it sits high
12:57 PM roycroft: but you see that i extended the casters well beyond the base pedistal for stability
12:57 PM roycroft: what i would do for the bandsaw is make the frame out of 2"x0.1875" angle iron instead of 1" tubing
12:57 PM JT[m]: That looks real stable
12:58 PM roycroft: and i would weld the caster pads to the top of the angle iron
12:58 PM roycroft: that way you can keep the saw low
12:58 PM roycroft: depending on the casters you use you'll only be raising it an inch or so
12:59 PM * roycroft was sad to sell that edge sander, but needed the space
12:59 PM roycroft: those casters are the double locking kind
01:00 PM roycroft: and you can both unlock and lock from the top
01:00 PM roycroft: you don't have to pull the locking lever up with your toe
01:01 PM JT[m]: I've not seen that type before
01:03 PM roycroft: https://www.amazon.com//dp/B09V9P581K/
01:03 PM roycroft: 150lbs/caster, so you have a 50% margin if you use four of them
01:04 PM roycroft: you push the outer lever pad down to lock, and the inner pad popd up
01:04 PM roycroft: you step on that to unlock
01:04 PM roycroft: when you lock it the caster cannot swivel or roll
01:04 PM roycroft: it's the only kind i use on my machines
01:05 PM JT[m]: Those look good
01:05 PM roycroft: they've worked out well for me
01:06 PM JT[m]: Thanks
01:07 PM roycroft: if you're concerned about the weight, you could go with 4" casters, which have double the load rating
01:07 PM roycroft: but you'd also be lifting the saw another inch
01:07 PM roycroft: unless you used 3" angle iron, or 3"x2"
01:08 PM roycroft: or did something else to lift the caster pad above the frame
01:09 PM JT[m]: Yup the saw base would be 1/2" off the floor
01:12 PM JT[m]: Geez this service is taking forever
01:16 PM roycroft: pardon the mess, but this is what i did for the drill press:
01:16 PM roycroft: https://roycroft.us/DrillPressBase.jpeg
01:17 PM roycroft: it's kind of ugly but it was quick and got the job done
01:17 PM roycroft: i might redo it some day, but it's worked for years, and i don't move the drill press around much
01:18 PM roycroft: this is my bandsaw: https://www.amazon.com//dp/B07H1BBC6Z
01:19 PM roycroft: i both needed to lower it a bit (i think 2") and wanted to recover the space below the saw, so i built a custom base for it
01:19 PM JT[m]: Looks workable to me
01:19 PM roycroft: https://roycroft.us/BandSawBase.jpeg
01:19 PM roycroft: again, pardon the mess
01:20 PM roycroft: i've been bad at tidying my shop over the winter
01:20 PM JT[m]: I like the drawers
01:20 PM roycroft: they are nice
01:20 PM roycroft: i like having all the tools i need for a machine at the machine
01:20 PM JT[m]: You should see my disaster area
01:21 PM roycroft: so if i need screwdrivers, wrenches, whatever, i buy extras for the particular machine and find a way to store them there
01:21 PM roycroft: i hate having to go across the shop and dig out the tools to make an adjustment to a machine
01:21 PM roycroft: so thd drawers on the right are for tools
01:22 PM roycroft: unfortunately, that resaw guide that i bought a year or so ago doesn't fit in the drawers
01:22 PM roycroft: i still have to fabricate some kind of storage for that on the machine
01:45 PM JT[m]: I need to make some kind of storage for blades on the pm1500
01:45 PM JT[m]: Lots of room on the back
01:49 PM travis_farmer[m]: Hmmm, i think it has been about a week or two since i have done anything on my machine... i wonder if it misses me?
01:50 PM JT[m]: It wants you to run it
01:50 PM travis_farmer[m]: i know it does, but every time i run it, i seem to screw something up somehow... ;-)
01:51 PM JT[m]: That's how you learn, if you take notes
01:52 PM travis_farmer[m]: mental notes, mostly... perhaps i should have a notebook out there though...
01:52 PM JT[m]: That could help
01:52 PM JT[m]: I used sticky notes
01:53 PM travis_farmer[m]: sticky notes lose sticky, and fall on the floor. i will probably just pick up a notebook ;-)
01:54 PM JT[m]: I also used magnets
01:57 PM travis_farmer[m]: will also be a good place to mark down changes, and other specific notes, as well as setup notes :-)
01:58 PM roguish[m]: I write stuff like blade length and guide bearing numbers on the inside of the blade protection doors.....
01:59 PM roycroft: you can write things on your spoilboard with a sharpie
02:00 PM JT[m]: I use a label maker for important stuff like min length for the planer
02:00 PM roycroft: and eventually transcribe the useful notes to something more permanent
02:01 PM roycroft: by the time the spoilboard is all scribbled up it's time to resurface it anyway
02:01 PM roguish[m]: all part of A G E. write it down and put where ya can see it.......
02:02 PM roguish[m]: or maybe it's just wisdom ................
02:02 PM travis_farmer[m]: i have a semi-photographic memory... but that is not to say it is in focus all the time ;-)
02:05 PM JT[m]: JT heads home
02:05 PM roguish[m]: JT: go take a nap
02:06 PM roycroft: i have a semi-photographic memory as well
02:06 PM roycroft: if i remember to take a picture i have a photographic memory
02:06 PM roycroft: if i don't i don't
02:09 PM travis_farmer[m]: Hmm, maybe tomorrow or friday i will get out to my machine... still have to rough out the machine control panel, once i have figured out what it is going to look like...
02:11 PM travis_farmer[m]: what i really need to do is clean out the loads of STUFF. can't hardly even work on my machine without something in the way...

04:31 PM JT-Woodshop: dang lifing eye is not on the center of gravity...
04:33 PM XXCoder: isnt that fine, helps land the machine properly?
04:33 PM XXCoder: but then im not too familiar with such lol
04:34 PM JT-Woodshop: easier if the eye is in the center
04:35 PM JT-Woodshop: but no biggie
04:36 PM XXCoder: yea
04:36 PM XXCoder: probably balance between center of mass vs frame strength
04:40 PM roycroft: how far off is it?
04:40 PM roycroft: would moving or removing the fence fix it?
04:40 PM JT-Woodshop: prob off an inch or so
04:41 PM XXCoder: hook is just bit forward from rear column
04:41 PM roycroft: remove the miter gauge and the fence
04:41 PM XXCoder: moving it forward a bit would balance it, but also stress on head and column
04:41 PM roycroft: or move the fence all the way to the let
04:41 PM roycroft: left
04:42 PM roycroft: that might get you close enough
04:42 PM XXCoder: interesting
04:42 PM roycroft: just removing the miter gauge might be almost enough, it's a heavy cast-iron one
04:43 PM roycroft: the real issue with the lifting hook placement is that if it's at the center of mass it might interfere with the wheel
04:44 PM roycroft: s/is/may be/
04:44 PM XXCoder: ah yes didnt think of wheel. true
04:44 PM JT-Woodshop: looks like there is some structure right in front of the current location
04:45 PM JT-Woodshop: anyway it's quiet and the blade that's on there is not the best lol
04:45 PM roycroft: i did not even try the supplied blade with mine
04:46 PM * JT[m] uploaded an image: (251KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/xRwcgliYKrgUzachieHtwHmR/20230329_164439.jpg >
04:46 PM JT-Woodshop: I'll put the woodslicer on tomorrow
04:46 PM XXCoder: its like printer starting ink thing, it sucks and lasts short time
04:46 PM XXCoder: *I guess
04:47 PM * JT[m] uploaded an image: (199KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/yZUZdySTdjgUqwoeCSFarYtg/20230329_164544.jpg >

04:48 PM XXCoder: yeah hook attachment is right between 2 strong beams
04:48 PM JT-Woodshop: I guess they put the bottom wheel down low to help with the CG
04:49 PM roycroft: or to keep you from installing a nice base cabinet like i made for mine :)
04:49 PM roycroft: but really, it's probably for the foot brake
04:49 PM roycroft: it looks like there's plenty of room to build a blade/tool storage cabinet in the bottom of the saw, though
04:49 PM JT-Woodshop: yup that makes sense now
04:50 PM JT-Woodshop: I really like the foot brake even for just shutting the saw off
04:51 PM roycroft: it would be a good feature to have, indeed
05:05 PM JT-Woodshop: JT makes a shopping list for tomorrow to wire up the bandsaw
05:28 PM roycroft: have you decided on a mobile base design yet?
05:30 PM JT-Shop: I'll go with some kind of mobile base but not sure exactly which one or if I'll build it myself
05:33 PM roycroft: if you have the time and inclination i'd suggest building one
05:33 PM roycroft: but i always look for an excuse to weld stuff :)
05:33 PM JT-Shop: things are slowing down a bit for me
05:34 PM roycroft: the truth is that i prefer mobile bases that are made to fit the machine, and i don't like the casters on almost all the commercial ones
05:34 PM roycroft: having to adapt a machine to fit a mobile base is not fun
05:34 PM JT-Shop: I like the casters you linked
05:35 PM roycroft: i have that type on every machine i own that is on wheels, except for my table saw
05:35 PM roycroft: and with the rethink on the cnc router, the table saw may be getting those casters very soon itself
05:36 PM roycroft: i already have a vision in my head for moving my conventional router table to the end of the tablesaw
05:36 PM roycroft: and i think it will work out there very nicely, as long as the cnc router and the tablesaw are at the exact same height
05:37 PM roycroft: my current router table is exactly the same height as my tablesaw, so that shouldn't be a problem
06:01 PM * roycroft has also decided to go back to a biesemeyer type fence for his tablesaw
06:43 PM skunkworks[m]: roycroft: Update on the email issue.. The company is owned in china - they were using a pretty cheesy provider http://www.dnspod.com for dns.. They are moving it stateside and suppository it has fixed the problem.
06:44 PM skunkworks[m]: 'pretty cheesy' their words - not mine.
06:44 PM skunkworks[m]: supposedly...
