Re: Feed rate increase and crazy thread milling, just for fun
I've gotta get some sleep, but once I do, I'm going back and downloading all the photos you've sent to a folder of it's own for study. My weekend is kinda jacked up, as my shift is changing slightly.

Re: Feed rate increase and crazy thread milling, just for fun
I'm thinking cut rifling, but button has some advantages, and disadvantages, that differ from those of cut rifling cutters. So I may have to play with both, and see which works better for the things I

Re: Feed rate increase and crazy thread milling, just for fun
Bill, Look where all the gears used to be feeding the gearbox, took "em all off and put the chain/sprocket stuff on. Way cheaper than new gears for kind of a 4 off part! Worked perfect too. I made the

Re: Feed rate increase and crazy thread milling, just for fun
Saw the gear motor, and recognized it. Didn't see the chain drive. Was looking at some files I recovered off an older computer drive, for cutting gears on a shaper, with a wire wrapped around a

Re: Feed rate increase and crazy thread milling, just for fun

Re: Feed rate increase and crazy thread milling, just for fun
More than happy to tell you what I know. Are you trying to do cut or button rifling? Can't really help on either specifically. I have a hammer forged BSA barrel on my hand rolled PCP rifle. Except for

Re: Feed rate increase and crazy thread milling, just for fun
Did you see the red marks on one of the sprockets? For a 8 start internal thread with specific start and end orientation. More thread milling! Used to do all that in the lathe, that's a whole

Probably not, this is caveman technology! I do like it though. Maybe here's a pic or 2 of the application. Dave Matticks

Re: Feed rate increase and crazy thread milling, just for fun
I know it's not Craftsman or Atlas but a little food for thought. You can really do a lot with a little if necessary. Note the gear motor coupled to the drive motor and chain drive with compound

Re: Feed rate increase and crazy thread milling, just for fun
I would be interested in hearing more about what you did, and how you went about doing it. I? hope some day to be skilled enough to make a rifling machine, and it looks like what you've done here

Feed rate increase and crazy thread milling, just for fun
Hope I can find the pics of part of my never ending project from a few years ago. Needed to cut 1" pitch on a 4" diameter part 24" long. Here's the kicker, 2" root diameter. Don't remember the angle

Re: 10" tailstock on a 12" Craftsman lathe?
No. The tailstock turret referred to is a stand-alone unit. It is lever operated and has six adjustable stops. Also, it takes 3/4¡± tooling. The one that has a 2MT arbor and can fit into the

Re: 10" tailstock on a 12" Craftsman lathe?
Atlas made three types of tailstocks for the 10¡± and 12¡± lathes. The standard tailstocks (the ones that came with the lathes) are not interchangeable. The 12¡± ones (early and late) are 1.000¡±
