Gunsmithing How do you cut this angle.
- Thread starter LC 6.5 Shooter
- Start date
With precision, unlike that arrow you drew.
Ok I tried for a little more precise arrow if that helps you answer

Put a boring bar on your toolpost, set your compound rest to the appropriate angle, then feed with the compound rest.
Or, am I misunderstanding your question?

Dremel. Maybe 2 beers and 30 minutes of grinding

This is the way
Might need two boring bars, depending on the insert geometry. Wicked fast on a turret lathe.
I use a tiny boring bar and leave the compound at the same angle as threading (29.5 degrees).
Now that you've got your lathe set up, gonna do any form 1 builds?
I just finished my Mk1 integral build. Been wanting to add one of these to my collection for awhile, but it took 6 months to get the form 1 back. Built it with a late 60s mk1 I picked up at a local pawn shop.
I got to use all 3 of my machines on this. The manual lathe, manual mill and CNC mill. The first rnd pop is a little annoying, but otherwise it sounds great.
The hardest part was building upwith TIG, and machining the front sight boss. Cobalt cerakoted with G10 grips.
BTW:
If your looking to get your feet wet on a practice project, and end up with a useful chambering tool, I uploaded drawings for my 2 axis floating reamer holder design to hobby machinist. You can download the pdf's here:

ER20 Floating Collet Chuck/Reamer holder files.
I just spent a couple hours converting my floating ER20 collet chuck / reamer holder models from Inventor, over to Alibre Design and recreating the dimensioned drawings. If any of you guys are interested, I uploaded the drawings in PDF, hopefully you can download them strait from this post...

Have you tried getting a little CO2 dispenser and spraying it down the inside of the can before the first shot to purge all the oxygen?
No. But that's a damn good idea!
This looks like just ticket!

I've used wd40 and water, both of which create their own problems.

On a manual lathe, a boring bar can be used for the chamber pre-bore (if you’re into that sort of thing), counterbore, counterbore chamfer, chamber chamfer/edge break, and then run your spindle in reverse and chamfer the OD on the backside. One tool, one compound setup.
