I do thread these on a lathe...

Here's the receiver end of the barrel being threaded, ~.704" x 20 tpi...

I've also re-tapered the 'fat' taper...

Next will be threading the muzzle end...I'm still deciding whether to make a threaded front sight base + band or saw off an old Luger front sight base/band and thread it...

I thinned the big end of the taper down about .085" off the OD; left the front sight band end alone. It looks a bit better. Here's a comparison of before & after -

A member pointed out to me that a 4" Luger front sight band + base would be too short for a 6" 'Navy' style barrel...So I guess I'll be making one from scratch...

I looked at Ed Tinker's albums, and Ed has a Navy pictured -



Unfortunately, Ed sold it. I can try to extrapolate the front sight base height from the pic...But if anyone has a Navy (or a repro) they could measure, it would make it easier!

Thank You!

In the meantime, I'm working on the front sight base/band blank...

Continuing to mill the screw-on front sight band + base...
