Got my Drill Press and Bit, so hope to try this soon..
As you can see a little bit in the picture, I actually used the bottom half of an airtite with the foam ring in it to hold the chip, got the idea from @Wifey 's post. I placed a HS $1 chip I'd popped the inlay out of in the airtite then centered it by lowering the router bit and scotch foam adhesive taped it in place. Set the router depth to the stock Paulson label inlay depth based off the HS chip and voila.Very cool. Three questions. What is your setup for centering the chip? Did you eyeball the depth each time or have it preset? Explain your router setup. Thanks!
All I can say is...AMAZING SUCCESS!
I've milled my first two racks of THC, and when perfectly centered a 15/16" diameter mill will just reach the inner ring of the THC and give a great flat surface for a 15/16" or 7/8" aftermarket textured sticker. With the exhaust flange jig I can do both sides of a chip in about 10 seconds.
Only 2860 chips to go! Afterward, I may be able to offer limited milling services to forum members!

Great to hear Berny. Any pic's of your set up?
My thoughts so far about this setup vs. the more popular drill press milling method:
PROS:
1) Consistent mill depth. Doesn't matter how thick the chip is. As long as the jig is securely fastened to a flat surface, the router bit will always mill to the same depth because you're approaching from beneath. And the router allows for good micro depth control, so you can easily switch mill depth to shorter (for more worn and smooth hot stamps) to a bit deeper (for chips with more preserved hot stamps like minty Starbursts). This fine control allows you to mill the minimum depth possible, therefore preserving most of the chip's original weight.
2) Smooth serial operation. Just keep the router going and you do chip after chip. No need for turning the machine on and off between chips or between sides of the same chip. Depending on how much dust I'm creating around the jig, I can usually do 20 or even 40 chips in a row before stopping the machine to clear the dust and taking the milled chips out of the rinse water to the drying table.
3) Fairly easy to center. Yes, you can eyeball it, but always do a few practice chips (maybe on some cheap plastic or leftovers (I use some old random ASMs that are not part of sets). I centered my jig by first drilling the 3/8" hole that the router bit will come out of, then placing a 2" diameter fender washer with a 3/8" center hole directly over the first drilled hole (sticking the whole drill bit in to keep things steady), and then fastening down the exhaust flange around it after that. Then I line up and lock down the rail guide, and add an extra clamp on one side.
CONS:
1) Dust, dust, dust. This shit gets everywhere, even if you're milling just a teensy weensy little bit. Always wear eye protection and some sort of mask Vacuum system would help, HOWEVER it is good to have a little bit of dust, as it does act as a lubricant to help move the chip around in the jig a bit easier. Protect all surface that you don't want to get dirty. I even had to stuff a towel below the door leading into the house because the dust will get through.
2) Doesn't handle warped chips well. As always, for best/most efficient results, chips should be flat before milling this way. A drill press would have the advantage in speed with a warped chip. But more chip material ends up getting milled away regardless of method used.
3) Hand cramping after repeatedly using the dowel to spin the chip inside the jig. Probably would be best if I rested for a bit after doing each rack, but I try to do 2 racks at a time (for this project, at least) so that I get each colour done at once.
I'll edit as I think up some more stuff and get more practice.
So, I guess next step is to make a video?
So glad to see you milling @allforcharity!
I will add a slightly older video I have of my basic milling setup. I actually have a finger guard that this video doesn’t show. I was milling a CPC HHR set yesterday and I should have taken a video. I will probably do more tomorrow and create another video with me aligning the press and showing the finger guard.
My speed milling hotstamps is about 30min/rack and so far a little bit longer milling inlaid chips at about 45min-1hr per rack because of how precise this needs to be and some additional cleanup.
It isn’t obvious in this video but I put the entire drill press in a very large cardboard box with the front cut away and this contains all of the dust and debris.
Here's a short video of me working with my setup above:
For some reason, these chips went easier. Two racks done in about 1h 30min.

Nice video...I love seeing these. I've been tempted to set up something similar. One thing I have noticed is that the mold impression into the clay is not always center. Have you noticed any off centered cuts in reference to the first inner ring of the mold? I'm always constantly adjusting my jig to center my cuts. Then again I'm pretty anal
It's funny, general pacing really ramps it up. When I started I was about a rack every 90 minutes. Now I'm to a rack every 45 minutes just with fluid movements.Here's a short video of me working with my setup above:
