[The50jrh]

I need some parts for one of these any idea where I can get the indexing plate and indexing hand? I have been looking for a while and this is the first one I have even seen looks awesome hopefully I can get the parts to fix the one I am using!

Bless you boys for keeping American Gunsmithing History alive. With the executives of the American gun companies chiseling away at the use of "hand work" and making barrels cheaply all in the name of pure profit this video warmed my heart. Keep up the great work and maybe one day I can buy a barrel from you.

Are these bullets available, the 180gr Burger bullet that shoots at 3450fps?

Sounds like a winner to say the least!

How is it different than button rifling, what's the difference?

[grayswandir47]

I see the barrel being indexed but cannot tell how much. Is it a new groove or is it making the same groove wider? How many passes does it need to cut each groove?

[bombdoc42]

Excellent - nice to see an old Pratt & Whitney doing its thing...

Pity about the colour though! Old machines should be grey - it's more diginified!

The cutter is long, doesnt it never bend? Or only if you try to take off to much material in a single stroke?

[JesusHitlerForPrez]

@wilco490 It cuts on the return stroke. It will stretch but not bend.

Is this a P&W model or custom? Either way I'd love to spend a week going over that machine and learning everything my head will hold. Glad to see people preserving and using these fine old machines. Most are now smelted and turned into something "usefull".

The cut is adjusted by a taper that is inbetween the square headed screw on the end of the rifling head and the actual cutter. When the rifling head comes all the way out of the end of the barrel and "hits" the sprocket adjuster at the end it advances it about .0001" each pass.

How is the depth of cut adjusted?
