This is a fantastic build and a pleasure to watch unfold, thanks for sharing!

Can I ask how you determined the angle of conversion for the barrels?

And you asked to be reminded to share some info on the jointing process with the hinge pin removed and excess material left on the forward lump? I would appreciate hearing more on this if you could, thank you!

Mark;

The convergence angle of double rifle barrels is not an exact science by any means, and to me is largely a matter of experience. On this particular rifle I converged each barrel to the center line of the distance between the firing pin holes at about .040" at the muzzle of the 22.5 inches of barrel length--meaning that the center of the bores are .080" nearer each other at the muzzle than at the breech. This is a good topic for you to research with some of your current colleagues.

One of the members of this forum, Ron Vella, has built about 6 double rifle using Brno zp49 actions and I hope that he will provide input as to how he came about deciding on barrel convergence, as he is a expert at it.

I will remember to discuss the jointing of the barrels in future posts.

Thanks;
