Finished my first chip. Made the mistake of not reading this all the way through and didnt get the Magnate bit so the chips are a little convex but have a magnate bit on the way now to get it sorted out

Awesome job! how convex did it turn out? I assume one of the common Amazon bits like Yonico or Excel?

Beautiful!
The Magnate bit is great, but it does leave behind a small amount in the very center, and if not removed, you'll feel it after the label is applied.
Before labeling, a small scrape with a sharp blade nicks that right off.

Thank you! It is definitely noticeable by sight and touch. The PDC label in the picture is thicker and textured so it hides it pretty good but I have some thinner labels that dont cover it at all. I'm fairly certain it was the yonico. They're still plenty usable and but it's just enough to drive me crazy so I'll give the magnate a shot

Thank you! I'll keep that in mind. I'm sure it wont be nearly as bad as the cheaper bit I'm using now.

And for anyone wanting to try this dont overthink it. I took a piece of probably 1/8" uhmw, pretty sure thats it, basically just plastic ran a 1.5" hole saw through it at the edge and wood screwed it to a piece of butcher block. I did have to tidy the cut up with sand paper but the chips fit really tight and I prefer to just eyeball each chip so it's not bolted down,to the drill press. It is a significant piece of butcher block so it doesnt move unless I make it move. Just give it a shot.

No hate on fancy precise jigs or safety measures if that's you're route go for it!

Interesting. Does this show up after the bit has been used for a while? I've done about 50 chips so far with my rig and the center of the chips is as smooth as any where else in the milled area.

Mine left this tiny bump from day 1.
Here’s a couple photos:

Dang, just put my Magnate bit under magnification, and the center, where the the two blades come together, there’s a small chamfered edge on both blades. It’s too perfect and identical on each blade to be by accident.
Maybe other Magnate bits are not always like this? Very interesting.

I figured it was that the blades just didn’t come together in the center...
If no one else’s bit is like this, congrats!

I think I understand your issue, but I’m not sure what is depicted in the pic.
 
Looking good. Did you get a Harbor Freight drill press.

Im not sure if you're talking to me, but no I have a larger drill press i've had for a while. I need to check what speed I was using but it seemed to work well and surface finish was great
 
I'm currently building a milling rig myself and came up with the following design after reading through this thread.
Since @Eloe2000 mentioned, that one has to push the chip against the other side of the holding rig I thought to myself, why not just make a V cut into the wood and start pushing the chip in there straight up. Do you guys see any flaws with this idea?

FIY the rest is going to be the way Eloe proposed.

Remember that not every chip is centered. Actually, most of them are off a chunk. Make sure that the jig itself can be mounted and moved easily to get the chip in the sweet spot.

Other people have done this. I don't see any reason why not necessarily. Potentially there is more room for it to slip or pop out. But that is just a theoretical concern. Give it a shot.

Depending on how worn the chips are circumference-wise, the center of the chip will not always be in the same place and your milling will be off.
 
Ok, luckily the drill I'm using enables me to adjust the jig easily! I will try everything out tomorrow and update you guys here!

Actually, if I hadn't retired from milling, I had wanted to create some spring loaded (or tension loaded) mechanism to keep the chip into place. If you want to get crazy I would think about that problem for a minute. This would free up one of your hands.

When I retire, I'll send you a PM. I have a mechanical jig and it's amazing.

Honestly I hadn’t thought about it much. I would probably walk around Home Depot and try to find a sling mechanism I could retrofit for this purpose. Just realize you don’t need to apply a long of pressure and you also want to make it efficient with your time. I think some of the suggestions here will hold the chip rock solid in place but will take a fair amount of time to do and undo each time.

Also, my original jig worked but wore down a bit over time and the circle diameter widened. It still works without holding the chips for wider chips. And for narrower chips I could just buy a bit of tape inside to make the fit more snug so the chip doesn’t spin as well.
 
Ok, as promised, update time!!!

Today I wanted to cut out the V shape for the milling jig but before I even got started I realized that I didn't have the right tools for the job.... damn that's anticlimatic, sorry :ROFL: :ROFLMAO:

Will give it another shot tomorrow with different tools.
 
Ok, you know how life goes sometimes. The past week has just been busy af.

But good news are, today I managed to build everything.

So here goes my building pr0n and my experiences.

Please excuse all of the wanky a*s lines. I dont know what happened either xD

Here, the idea and the finished product. Although my lines where off af, this turned out quite nice!

And here you can see my first try on the left and about three chips later another chip.

And now a picture of the chip in the milling jig:

So my experiences:

So I read on here that a slower speed is better but I can assure you, 200 rpm is waaaaaay to slow. I figured that about 650 rpm was more beneficial because I felt like the milling bit didn't catch that much on the chip. I However forgot to use a rubber mat underneath the chip so I had to jam the chip in there using a piece of wood wich was not optimal to say the least.

Tomorrow I will try it again with a piece of rubber.

The alignment was a bit of a pain but the laser from the drill press helped alot and also the videos from @Eloe2000.

So far I cannot find any obvious flaws with just cutting out a "V" shape. If you guys see anything that is improvement worthy, please tell me. I wont take it personally, I promise :ROFL: :ROFLMAO:
 
When you first started the plan for this, I was afraid the chip may spin within the V-shape, and it looks like this was the issue. The problem is that the chip is only held in place by 2 very small contact points in the back, plus the stick. If the jig is curved and more “chip-shaped”, it will contact more and may grab better.
Certainly, a pad on the bottom should help.

Maybe a thin strip of rubber glued to the inside of the V shape will give more grip and prevent spin?

Btw, one of my first milled chips looks exactly like the one on the left in your photo. I didn’t hold it tight enough and spun and wobbled within the jig. You learn quickly what NOT to do. :ROFL: :ROFLMAO:
