Clamps for the Mini Pallet

[@lorenzoalmendarez5863]

I made one of these over 30 years ago and used it on top of my rotary crossslide when I used to cut cavities for plastic ejection molds. I heat treated mine and grounded it squared. It worked great and I still have it too.

[@ColeHomestead]

it was great watching/learning how you made the clamps but the idea of using the mini lathe & Mason jar as a makeshift tumbler was ingenious and will try this myself.

[@ChrisDePrisco]

Glad you liked it!

[@carryitaround]

Bruce witham has the best mini pallet design I have seen on KZbin. Thanks for your video Chris

[@ChrisDePrisco]

Awesome, thanks for sharing! I need to build a much bigger and better one soon so I'll definitely take a look at what he has come up with.

[@darreneck3744]

thanks for leaving in the broken end mill parts, very entertaining!

[@darreneck3744]

and the gouge out of the beautiful new spacing pallet!

[@erikisberg3886]

Hi Chris! Good work! Going to steal Your idea with the dowel pins next time I make one. I made mine about 3 times the thickness of Yours, around 1 inch, so they last longer and also give the screws more bite into the Al. I find remilling being the fastest way to align the fixture with the machine, so I do not worry much about scratching the surface at all. The Al has the advantage of not scratching sensitive parts. Another simple feature that can be useful is a removable backrest as on a surface grinder magnetic chuck. From another overengineering engineer...

[@Stefan_Boerjesson]

Fine clamps and inspiring video. CNC saves time and You can work and earn money instead.... Hopefully that money pays for the broken mills.... Programming for 50 years hand cranking has its charm.... Figuring out how to set up objects for "mass production" is another interesting part for a hobby machinist.

[@Mtaalas]

Aw... too bad you marred the nice surface... reminder to always use sacrificials under the work or to rotate the work-piece and machine in two passes. :)

[@TheMetalButcher]

It's designed for that. You face it off every so often.

[@JF32304]

I still wouldn't do that to that surface. I would have just raised the clamps up above the surface just slightly.

[@egx161]

Angle blocks come in really handy. If you mill those angles on an angle plate, upside down, using the sides of the end mill, it's easier.

[@lintelle2382]

love the de-bur jar!

[@kentvandervelden]

The lathe based tumbler on the lathe is clever. I like that. Were the cuts in the pallet very deep? Would it be better to stay a few thou higher and cut the parts out? I'm just wondering as I've not used a pallet. Best wishes

[@ChrisDePrisco]

Depends on how you view the pallet I suppose. I don't mind taking a few thou out of the pallet to not have to do the extra cleanup but I also see that particular pallet as "disposable". When it gets too many gouges in it I can face it back flat. Once that's been done so many times that it's too thin to use, I'd toss it and make a new one.

[@Harrzack]

Just discovering the pallet idea - really like the dowel pins you used. As others were, was taken by the tumbling job at the end. I now know about "ceramic tumbling media" - but the $64K question is how did you get the super looking black finish in the tumbling process?

[@Krispykashew]

Loved the tumbler.

[@jaroslavchytil5732]

Great ... would you mind to post your cutter tool ... thx

[@ChrisDePrisco]

Which tool, the end mill? I'm not even sure, I borrowed it from the scrap carbide bin at work and used it until there was nothing left, lol.

[@milspecmachine]

I knew you were using a CNC mill in your pallet video lol I guess you were technically using a manual mill converted to CNC lol great work man it looks awesome 👍👍

[@ChrisDePrisco]

+Milspecmachine Thanks! They sold both two and three axis versions of this mill - I only got the two. Still, it will work great until I can finish up my "mini VMC". :D

[@Terry_Baker]

Sweet work. I've been wanting to make a mini pallet for a while now when I get the time.

[@EZ_shop]

Very nicely done. How long did you have to tumble them to get those results?

[@ChrisDePrisco]

+Crivo152 Thanks! I left them in about 3-4 hours.

[@pabloperez5678]

What kind of stone have you used? great video!

[@nikolaiownz]

Cool deburr idea.. where did you get the deburr things in the glass from?

[@ChrisDePrisco]

+nikolaiownz Harbor Freight, actually. It's just called ceramic tumbling media and you can get it from many places. There are also tons of sizes and shapes for different uses. I had to break mine up some because they were just too big.

[@dzarren]

You plunge into the pallet at 11:24?

[@ChrisDePrisco]

+dzarren Yes, I'm not overly attached to it. I'd rather scar it up a bit and periodically face it flat again than go to the effort of trying never to put a mark on it. Also, it's basically a practice project; I won't be using it much longer.

[@madsighntist14]

I agree with Mtaalas, After the Time & Materials put into your Pallet, I suggest even 1/8th-inch sacrificals under your "make Clamps project". I keep all scraps of material, and I would guess fairly anal about it as I Strive to separate them by thickness! One could say the Pallet itself is the Sacrificial Part, but There were Two broken Milling Cutters broken, and a third to finish the project. That is an Expense, at least for me! Otherwise, a Great Presentation & I'll keep watching

[@Westmach]

only 20 mins?

[@r3vo830]

Quite some expensive clamps you got there. Thanks for the video ;)

[@ChrisDePrisco]

+Revo SeR Ha, tell me about it!

[@TheLydras]

u messed your surface as messed yor vise either :(

[@anthonybutt9458]

great idea, another project on the list!

[@Danxp202]

Couldn't you just find two milimeters higher material, and mill it two sides in vise? Or not destroying pallet by milling 0,1mm above?

[@Legend-fq8tz]

22:48 what is that

[@56Moto]

Yes, What is that ?

[@laurentcnc6662]

Nice vid. I would have put some sacrificial shims between the mini pallet and the stock to avoid machining marks on it. It's always with mistake that we learn ;-) I do not know how you set your G code file, I would have use contouring only, without complicated trocoïdal cuts in the midlle. Always make it simple with less chips volume to remove. Keep going.

[@alexc5369]

hey, great video. what is that crushed stuff that makes the coating on the parts?

[@ChrisDePrisco]

It's just cheap ceramic tumbling media from Harbor Freight.

[@19dannydude97]

What's the song name?

[@RangerM98]

I too was scratching my head just before the endmill broke ;)....I was thinking, "what in the heck is he designing in there with an eccentrically drilled hole ...and why did he do it after the initial pass.....then it broke and everything became clear :)

[@Tchefter]

wow! wow! WOW! very nice! and... better cutting air then other stuff like your vise :-)thanks for this great Video...

[@ChrisDePrisco]

+Tchefter Thanks!

[@tylermerkley3055]

what mill do you have

[@ChrisDePrisco]

+Tyler Merkley This was made on a Lagun FTV-2 with an Anilam 2 axis CNC controller.

[@a0cdhd]

You might like to consider putting a black oxide finish on those nice clamps you made mate. Tablespoon of sodium hydroxide (caustic soda) in a pint of water should do the trick. Heat the mixture to 140°C then add the clamps. Make sure they are clean. Slosh them around for about 15 - 20 minutes then take them out and rinse. Repeat as necessary. Better do it outside as the fumes are a bit toxic. Wear gloves, eye protection, rubber boots, face mask, leather jacket, fire proof apron, hard hat, ear plugs, respirator and anything else that the workplace health and safety nazis think might be a good idea.

[@ChrisDePrisco]

Interesting... I never thought black oxide was an easily doable home thing, thanks!

[@a0cdhd]

"Blueing" is a general term for surface treating steel to inhibit rust. The results can vary, depending on what chemicals you use. Colours can vary from black to grey, peacock blue to straw coloured, shades of green and brown etc etc.

[@GiacoWhatever]

Nice job dude

[@gregorymaider6939]

Home made tumbler is genius, overkill of course but clever nevertheless

[@MultiAndreasH]

P.S. schon mal etwas von gegenläufigen fräsen gehört?

[@joshuapitts4286]

love the videos, but you tore up your mini pallet already making the clamps! It is such a nice piece it bums me to see it tore up lol.

[@ChrisDePrisco]

+Joshua Pitts Yea.. I know, lol. It looks worse than it is, only a few thousandths deep scratches so it's still functional. Once it's all mangled up it can be quickly resurfaced with the flycutter and that process can repeat for quite some time. I won't be using that one much longer anyway, I'm going to make a much better/bigger one and I'll take more care of that one. :)

[@jaymund1130]

Very nice video

[@miauneko2775]

Hola Cris muy padres bridas se te rompieron varios cortadores:( me agrado el proceso de maquinado 👍

[@МихаилБалахин]

Эх, жаль подложку, хорошая была, ведь чуть-чуть можно было оставить расстояние, а остальное с припуском отпилить, и отшлифовать. Но все равно, мне это очень понравилось, спасибо вам большое, за ваши труды

[@mrdnice425]

Thats exactly what I was thinking. Well said!

[@whitefiddle]

Pretty klutzy work, dude.

[@andyneal8271]

Well that fucked up the new bed. Hope the over engineering was worth it. Have a look at the instructions of the machine it might save a few end mills.

[@brettwatty101]

Hahha, you need to break some eggs to make an omelette.

[@thatoldbob7956]

It's entertaining, good work with nerve wrecking music. Is it really nessesary????

[@mrcpu9999]

Enjoyed it, but the music was painful. So I guess I didn't enjoy it, I tolerated it. But no more.

[@Chris-bg8mk]

Nice work, quality video, awful music! ;-)

[@czechbaron111]

I guess you're an engineer and not a mechanic as you overkilling it.

[@ChrisDePrisco]

+Jirka Šlechta I'd agree with that, lol.

[@RangerM98]

Nothin wrong with a little overkill....if you are going to take the time to make a part yourself you might as well make it good (fact is that the extra time and material costs are immaterial in a one off operation (even if it didn't have to do with the creation of tooling....(I am a Mechanical Engineer too fyi...so I totally agree with what much of the world calls, "over-kill" to be the "De-facto Standard' if possible :) ...(i assume you are mech...but I know it isn't necessarily so). Keep up the nice work!

[@ChrisDePrisco]

I'm a Mech in spirit but not in schooling. :P I just love to make stuff and love even more to make it overbuilt and last forever. I wish there was more of that attitude instead of the "disposable" culture we have now. It doesn't NEED to be made of Invar but why not? It's awesome! (I will make Invar parts... one day...)

[@KodyBear5605]

ya do good work, but I can't tolerate that noise...

[@arthurdavies6922]

quit now before You destroy the rest of Your tools

[@bobsorenson5761]

Music is terrible. Can't heat you talk.

[@shadowbannedagain1737]

EMBARRASSING MUSIC... I DIDN’T REALIZE UNTIL SOMEONE WALKED IN... REALLY GUY.....

[@richardwills3927]

Omg you are wasting drill bit's use coolant dude

[@thomasbroomfield5871]

Can't believe I literally just watched the video of you making the sub plate, then the next video I watch you mill straight into it 😒 makes me sad. Stop 0.1 short and burrs come off easy!!

[@DSCKy]

You're doing a lot of climb milling... which kind of goes against convention.

[@ChrisDePrisco]

+DSCKy Sure, on "normal" manual mills, but this one uses ball screws so the normal problems of climb milling and backlash aren't applicable.

[@DSCKy]

I wondered if CNC made a difference and noticed that you did a lot without any issues, then you broke a couple of tools so I wasn't sure.

[@ChrisDePrisco]

Haha, yea... The problems with climb milling are pretty much about backlash in acme screws and the cutter pulling the table around. Since ball screws have no backlash, it's no longer an issue. So it's not really a CNC thing, just what type of lead screw you have. Now, most CNC machines have ball screws and most manual machines have acme screws, so there is a lot of overlap, but there are manual machines that use ball screws, too. Of course there are somewhat different problems with ball screws on manual machines but that's a topic for another time. :) I broke tools because 1. I'm a noob. 2. I was pushing dull cutters too fast with poor chip evacuation and lubrication (because of #1).
