Milling one barrel in under 3 minutes. Go time.

Impressive... I'm hoping to have my own relabled paulsons in the 12 to 18 months and milling chips may have to be part of that project - you make it look very easy.

The hard part is getting a drill press setup, once that’s dailed in it gets easier.
 
Well done!
You don‘t have issues with crumbling edges, if the original recess was not dead center?
 
Are you milling at a very low speed or is that just how the camera is picking it up? Also, do you have a pre set depth that stops you from over milling too deep? Nicely done!

The camera is doing tricks, but it is also very low speed setting on the press..
 
Never had that problem,
I’ve been trying to not go as deep.
Interesting.
When the jig cross a decentered recess, there‘s no clay crumbling off that new fine line?

How much you mill off / how deep is the recess after milling? ~.25mm is about usual.

Thx
 
No, I don’t think so, at least not a critical amount. I always send them for a water bath and a wipe down after, there is small particles abound the edges, but I wouldn’t consider it a “crumble”
 
Here’s a few random samples where they aren’t perfect centering. Close ups. This is the worst of the chips, all different chips.

I am by no means an expert, but I don’t think any crumbling going on.

I am thinking of trying to build a milling jig to do about 1,200 Paulson THCs (which have hotstamps)... Any tips on building one?

I also had the same question as someone above, about whether you have a stop set on the drillpress or if you are just doing these by feel as far as depth.

I would definitely set a stop set on the press. It’s really the only way to have uniformity across all the milled chips.

Also cheap “oops” insurance- lol.
 
The milling looks good!

Your fingers getting that close to the bit worries me though. It just takes a moment of inattention to cause an injury.

Unfortunately this is only true if all the chips are of a uniform height, since you are going top down. This is why I prefer the bottom router method, because your drilling depth is always in relation to the surface on which the chip rests, not the chip itself. It also means a simple circle jig.

What’s the bottom router method?
