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

IF I ever actually get around to the point where I can start building the things I dream about, I'm probably going to use a 2x4 for the stock. As far as woodworking goes I'm a wood butcher. Or a rough carpenter. VERY rough.?

That is a beautiful piece of work. I am not anywhere close to being that skilled yet. Did get some good news last week. Wife does not have breast cancer. She does have a weird infection, and the antibiotic to treat it has a long list of scary side-effects. She's delaying taking it for now. But I have official permission to go back to class this week. Lord willing and the creek don't rise, I'll be back in class tomorrow. Thinking about making some stuff for my shop among the class projects. Tripped over a website this morning that has a free machine shop course, and project drawing to make several useful tools. Downloaded the drawings and shop notes.?

Should have been working on house and shop, but it's been a crazy week, and I had to make up missed time at work so didn't get a weekend and did really scramble my sleep schedule. Almost time to go back to sleep so I have 8 hours of sleep before I go to work tonight.?

Need to do a few things for her, and a few for my shop, and make sure I'm ready for work tonight.?

Y'all have fun!

Hi Bill,

Hopefully here's some pics you might find interesting.

.177 cal, precharged pneumatic. Get around 55 shots on a 3000 psi fill.

The stock was the most difficult part for me!

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 want to do. I'm thinking something for pistol barrels first, as much for practice and play as anything else. And I'd be delighted to see any photos you want to share!

After a 20+ year hiatus, I've recently gotten back into reloading, and casting bullets, and I've wanted to make a, call it a .45acp Magnum for lack of a better description, 1911-style pistol in the .44mag power range. Or an 1896 Mauser in the .30 cal version. Or both. ;)

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 the barrel blank, scope and some screws it was made by me. Got pics if you're interested, it's kind of cool.

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 could be helpful to know.

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 or radius at the root but you get a sense of the process.
Single point was NG, milling was the only option. 2 pcs. 303 SS and 2 pcs. Delrin. 1 each left hand and right hand.
Not regular screw threads. Feed screws for pleated filter media to glue the ribbons on.
I love a little challenge once in awhile.
