Milling rig idea for help and criticism. (1 Viewer)

A little too deep, I think with these labella you really don’t need all that much, just get past the stamp bit. Overall I went too deep.

I can machine anyone a fixture out of billet alum. if anyone is interested I could also make it with a different top plate for different size chips.

I’ll take you up on it man. I would love a machined top plate, basically like the top piece of rubber, but thinner than a chip, something perfectly sized to sandwich into the two pieces of rubber I have. to hold the chip snug. The rubber gives, even if just a slight MM for a split second, but I can feel the chip jerk a bit and if it were machine sized and harder... I tried to Xzaxto a piece of thin hard plastic to put in the middle, but even on the third try it just wasn’t perfect enough to actually help.
 
Finally got around to do some more milling today and I tried some different jigs this time but went back to my original jig which proved the most efficient and least likely for failure. Basically it is just a drilled out piece of thin wood the same circumference as a 39mm Chip. I then sandwhich a thin piece of silicone in between another piece of wood. This gives enough grip that I don’t even need to brace the chip with a tool which I had started out doing.

@The Nuts Also the Magnate bit seemed to produce completely flat results for me. No nipple in the middle of the chip etc. The best of the three brands I have tried.

Here is a video milling a couple chips in a row so you can get a sense of the speed as well as a close up of a chip at the end. I am little faster than this when I am not holding a phone in my other hand. I up to about 2-2.5racks/hr once I have the jig aligned perfectly.

Oh, I also don’t recommend sticking your hand this close to a spinning bit but I had been doingthis for quite a while and was confident doing it for some small stretches of time. No need to warn me.

Loving the cardboard box idea!! So helpful.

how did you drill the 39mm hole in the wood?

Yeah the cardboard box looks pretty ghetto but it lets me just blow the shavings out after every chip and not make an absolute disaster of a mess. Super easy cleanup.

I used either a 1.5” spade bit or a circular hole saw drill bit. It is very slightly smaller than 39mm but allowed me to sand it down a bit and still fit a chip snuggly. I have both bits and honestly forget which I used when I originally made that piece, but either would work.

Wow! Looks like a great set up there. Thanks for posting the video. I had no idea you could mill a chip that quickly.

The thing with milling is that it takes time to figure out and set up a jig that works. Then every time you use it you need to make sure you have the bit aligned precisely. But once you are set you can rock and roll and tear through them.
 
Okay, different iteration, still used some rubber, but took your advice and today I was rocking a barrel in 7 minutes. This is my test rack and I had never used a drill press before. Here’s what I ended up with....

I think the drill chuck is a little wobbly, I tried to set it a couple different times, but I just think this cheap drill press is going to have some run-out. I think I can live with this though, I’m going to take the chips home and test the labels with this.

next time I’ll have a little paint brush with me, so brush out that fine dust collecting in the recess. It makes a difference to clean it out. Enough dust collects in the back to raise the chip and make my work deeper in the back where the is.

my top layer is actually a piece of 1/8 sign plastic. It’s not “hard plastic” I think it’s a pvc of sorts. But I took advice from @Eloe2000 and used a hole saw bit and then sanded it large enough. It has some bite and the chip clicks in.

cardboard box, game changer.

I no longer fear my mission of doing 4000 chips.

I am looking at a solid 25-30 real hours of work.

I can do it.

What size hole saw?
 
What size hole saw?
Looks great! How do you center the jig on the bit?

1.5” bit. Then sand. Had to do it twice because the first sand left it uneven.

once the jig is eyeball close, and hand tightened onto the platform.. I would depress the lever and bring the bit down (WITH MACHINE OFF) and look to see if the bit was centered on the chip. Tap softly with hammer if needed. Then I would rotate the bit 90 degrees and do the same. (See pictures). (Machine off) go around the chip this way tightening the jig when it’s good.

THEN ROTATE BY HAND

damn, and I assume you have tightened everything up and tried to determine the source of the wobble? Is this the cheap Harbor Freight press? If so that is the one I am using and not getting that run out like that.

Yeah you can see how I have like a second lip around the edge I think that’s where it’s off. Yes it’s the harbor freight drill and it does totally wobble. I can feel it in the Chuck that it’s off-center somehow. I put the chuck on three times hoping It was just misaligned. I know it’s not the bit because it happens with every other bit as well just off by like a Millimeter or two tried all the different adjustments on there To tighten it up but nothings helping
 
I just ended up using a three tooth lathe wheel as my jig. Tried it today and it's pretty dang good!

How did you attach this to your press?
Do you still feel it's the best option you've tried?
No clue! I just know it works. Milled a few thousand to it, it's not perfect or nearly as good as CDC, but it centers it automatically and gives me some adjustment ability for other sized chips.

Just use a vice on the table and pin it on. Once it's centered, it doesn't need to move pretty much from now on..
 
Is there a lot of weight loss? Does the new label make up for any of the loss?
Thanks

Yes - some chips get really light
Not really.... It's too minimal

The goal is to just remove enough to let the new label sit in. I have found if you go a hint too deep, you can't add material, but you can place a second inlay to bump it up.
