Anyone Mill RHCs? (1 Viewer)

I think you are talking about the 27mm t-channel (wood working) bit? The issue with that bit is it is sharp on the edges and the center "rail" (for lack of a better description) on the bottom has a gap. Theoretically, you could "double mill" (7/8" and then the 27mm) to git a flat bottom but I don't believe anyone has tried it.

I did order the 27mm (on eBay - Chinapak) to try it for myself.

Yeah, I've been thinking about giving this a try as well. I'm probably going to order this bit on Amazon, and attempt a double mill with 7/8ths first, then follow up with this. It will be interesting to see how even I can get the two seperate plunges.

I've also had a discussion with another member here who knows someone in the tool and die business who may be able to fabricate a 27mm / 1 1/16th bottom cleaning bit.

No, there is actually a 1-1/8” bottom cleaning bit on eBay now. I had never seen one before but someone just found it.

Yeah I bought one of those t channel bits to attempt double milling but had not gotten to it. Honestly I have no desire to mill RHCs so it was pure experimentation and low on my priorities.

I wonder if you could take one of these to a bench grinder and remove just a bit of material from each side to get it down to 1 1/16th? No idea if this is possible. Just throwing out a crazy idea.

I got a quote of $248 for a 1 1/16 bit, modified from a 1 1/8 bit. I imagine they do exactly what you suggest @TX_Golf_N_Poker, just very precisely.

I'm working with a machine shop to create a small setup for milling RHCs. Not for production... probably only 3-6 sides at a time. Lots and lots of manual flipping. We'll see if it's successful.

Someday @FordPickup92 will get back to it again...

It can be done... on a lathe. But we don't have a lathe currently to do this work. Maybe one day again... since we have hundreds of chips to do! Lol

One of these do the job???
this is the machine shop here in my building

Sure! Milling services. Only $4 per chip!

I think that 1 1/8 is too big. I bought it, and it arrived this week, and while I haven't put it on the drill press yet, I think you would have to be really precise.

My only RHC mission has been the hot stamp variety, and I think you can label over the hot stamp with a glossy label with no spinner issues or hot stamp bleed through so there's that.

The Clausing Lathe in pic #3 would do the job... way more machine than you need, but it would do it with a 8" - 6 jaw Buck chuck. My dad actually set Brie up with a collet from a mill and set a depth in the collet (basically a fixture or template) so that no jaw is actually ever touching the chip, and once you get set up it is plug n play!
