Tailgate

Thanks all! Yes, I have quite a bit of experience with the Dremel and Cratex...and yes, the ZING has happened once or twice in previous projects (luckily not on anything important). A few years back I bought a Forster rotary tool, and using the thinner pen-type tool really helps with the control, etc. I also have a foot pedal that allows me to slow and speed up the tool based on how much I am pressing on it (like a sewing machine does). It has it's pluses and minuses, but tend to use the pedal for most projects. The slower speeds definitely help prevent the ZINGs. I cleaned up the Ti cylinder, and it is MUCH better than it was factory. But I think I am going to get slightly more aggressive with the chamfer and use the cutter again to get a little wider / deeper cut. The cases are still catching on sloppy feeds (in other words, just throwing the ammo towards the chambers) so need a bit more bevel/chamfer. I hate doing something twice...but, I can't put the metal back on if I go too far. Ha! Carmoney: I am also skeletonizing a factory MIM hammer based on some of your posts / pics from years past. Keeping it "IDPA Legal" for now. I used a new extra hammer. If it turns out good, may swap it into my 625 then do the trigger on the 929 as a fully cut / bobbed hammer (i.e. not IDPA legal).

Hello all. I chamfered my first cylinder today on a new-to-me S&W 929 with the titanium cylinder. Thanks to all the posts on this forum over the years, I bit the bullet and did it myself. I used the 45 degree TiN coated cutter from Brownells, LOTS of cutting fluid, frequent stops to brush out the cutter and cylinder surface, and tons of patience. Based on suggestions here, I broke the corner of each cylinder with a stone bit in my Foredom rotary tool first, and did it so very slightly. That seemed to be the trick, as the cutter bit in immediately on the first attempt. I am happy with the results (see pic below), but do have a follow on question to which I think I know the answer yet would appreciate your input. Right now, the cylinder chamfer is just from the tool. I am assuming I need to "finish" it somehow to get a better polish / smoothness. Do I just use a fine Craytex bit in my rotary tool, or do I use fine bits of sandpaper, etc. (or both)? I would assume that sandpaper isn't going to do much on titanium. What do you suggest? Apologies for the "fuzz" from my paper towels and cleaning patches...this wasn't meant to be a beauty picture.
