Shady, In some obscure book I read about the proper speeds and cutting fluids* for Al which surprised me. Al needs a much higher speed** based on Machinery's Handbook. My first intro to practicing thread cutting was a mess because of I was timorous with the speeds. A 10X loop + diamond flat file to...

Re: threading titanium tube for endcaps

MX3 helix ( canned cycle ) has lead in lead out and flat bottom dwell for thread relief if needed Good point though!! Many thread mill vendors have free g-code generator programs that are preferred over canned cycles. Canned cycles tend not to have the lead-in and lead-out features that the thread m...

Just FYI OP, Bendersquint is a 02/07 (correct me if I am wrong here bender) manufacturer and 99% of the time will tell someone the option that has zero chance of getting you into trouble which can be pretty good in the NFA world as the ATF is convoluted and filled with stupid law.

So just to be clear, are you guys saying that cleaning anodized aluminum (TiRant45) baffles can be done safely with walnut shells, either in a wet tumbler or a vibratory cleaner?? Yes, they can be cleaned in dry walnut shells, the walnut will take decades to get it clean as it will polish the build...
