Before I end up having to redneck it or spend quite a while getting creative since I dont have that much tooling. Does anyone have a shop setup where I could easily come in and drill a few .22lr baffles for a form 1 suppressor build?

odd, I thought a heavy drill press / mill would be a better solution with a machinist vice.

My old lathe would takes months + parts to get back online.

Did you source a bunch of parts or did you do a kit?

Kit, bunch of K baffles just for a little .22 can. Usually would go commercial and take the wait, but for a .22 can I liked idea of trying to be fast and cheap.

Have neither, I have basic house/garden and some automotive, but not much in the way of anything more tradesmanish.

Which kit? I have a drill jig for Quietbore’s .22LR form 1

Funny you should say that, it is a quietbore .22 TI kit.

I had balked at it initially underestimating the precision ideally needed that and the $75 price tag. Up to sell and mail it or I could make a trip when I actually ever get a day off again. (68 hours this week so far..)

Ok, the TI baffles eat through the drill bits and you need to go SLOW. Too much heat will cause the jig material to expand and the hardened steel bushing to rotate and get stuck on the bit, as well as the drill to get off center. The aluminum baffles are pretty easy compared to the Ti.

I'd recommend buying about 4-5 of these: 9/32 Cobalt Drill Bit -mcmaster PN# 28765A26


9/32" 0.2813" 2 3/4" 1.07" Round 9/32" Split __ Steel, Hardened Steel, Tool Steel, Iron, Stainless Steel, Nickel 28765A26 5.35

You could do the TiN coated, but they are double the price and I'm frankly unsure how much better they'd actually be.

PM me your address and I'll ship it to you to use once you have the extra bits, and you can just send it back when done.

Please include your tele# so I can walk you through how I do it. The video online is a little too basic for my tastes, after doing several of these.

Yeap, knew I'd be ordering special bits and maybe some cutting oil. As well as the slow part, pecking or whatever they call it. Such a silly tiny baffle, kinda hard to imagine it taking as long as some have said.
