Ron-

Congratulations on the clean safety and success of your projects.
Your account on the use of barrel-band regulation widgets was good to hear about on the aforementioned thread. I got something out of it, although I'd definitely take the 'classic' route of tin shims and iron wire, adjusting with the torch at the range. I've been at the torch for most of my life and feel perfectly comfortable working in the narrowish margins of solder flow points on sensitive steels.

Bill-

Thanks for asking about the wee little 25-25.
I've been swamped with work this year, the labratory has been constantly expanding, I'm looking at a substantial expansion into a new facility some time before summer's out.
Combine that with the 19mo old girl and the little boy coming in June, I'm lucky to finish filing the sights on my Whitworth before next year!
I've been back and forth on barrel thoughts. I need to settle on a twist rate and have a couple of tubes made.
Really do need to get going on that thing, the kids will be ready to kill jackrabbits sooner than I think...
