if you want a V thread RB receiver, you are pretty much limited to the Spanish Oviedo. Or the Swede Commercially manufactured actions and even all of those were not made with V threads. Anything Remington military is bound to be square thread.
I don't necessarily have to have "V" thread, I have limited experience cutting threads on a lathe and just assume the ACME square threads will have their own set of challenges. Do you know, because I'm assuming the Danish Rolling Blocks witb have square threads too?

Just finished a roller barrel this week. 1897 pat. date with the sliding extractor. Made it a 45 Colt carbine.
If you divide 1 by the number of threads per inch and then divide by 2 you will have the size of the cutter for square threads.
Good to know, I would like to have a couple Rolling blocks in pistol cartridge, I have a Ruger Blackhawk in 38-40, that might make for a fine cartridge for a roller.

Get some rosin also for round barrels. They can spin pretty easily, and powdered rosin helps them grip better.
I went from using rosin to using powdered sugar, I think it works just as well and is much easier to clean up.
Glad to know about the powdered sugar. It's a LOT easier to find than rosin!
I became aware of the importance of using rosin when I tried to remove a VERY rusted breech plug from a muzzleloader barrel.The barrel kept slipping until I used the rosin. It really made a difference.

I will have to give it a try. This barrel wanted to turn so I cut a piece of the square mesh drywall sand paper and placed it between the block and the barrel. It worked good, however the block would suffer damage if used too often.
