Anyone think it will take more that threads centering the two pieces to maintain the required alignment? True, the opposing 60* threads are pretty good at centering, but I think there is still room for error. I think there would probably need to be some form of a boss or two with a very close slip fit, if not a slight interference fit on the connection. I mean, if this is going to be straighter than a chamber cut with a single form tool, these two parts pretty much need to align better than dead nuts.
I would make the adapter fit with as close of a thread as feasibly practical. I would also machine it from some high strength alloy steel, such as 4140 at around 38 RC, maybe even a 1 1/2 inch grade a bolt body. I have some left over 4340 pieces that we made some body fit bolts out of. I think we had it heat treated to 36 RC.
This would offer an anti- gall qualityty the assembly.
One thing I figure Wolf is doing is single point cutting the lead in the barrel with CNC. It would be easy and repeatable with the correct setup.
Since I do not own a CNC setup, I figure to Chuck the barrel up in the regular fashion and indicate that first 1/2 inch dead true, then using a tight bushing on the reamer, establish the lead and throat length with my regular reamer, being careful to run it in the exact, and repeatable distance.
I would rely on the properly fit threads to aligned everything.
