Guys,
This is a tough one. So much of the process is subjective, determined by the standards of whomever performs the process. Doug's work on fluid steel barrels was so excellent because his barrel prep standards were so high. I learned from him that 400 grit sanding was the minimum for Field Grade sets, going much finer for higher grade guns.
The basic process is easily found in Angier's book, which is a must for anyone intending to attempt it. In addition, both Gaddy's and Flanagan's processes for pattern-welded barrels are found on DocDrew's site. That's to get you started.
I can tell you that I must have done over 20 sets before I attained a result I thought was remotely acceptable, but even now I have reworked sets several times, literally being in my 12th generation of methodology and to the point that I'm not merely satisfied, but happy with my work.
I think that the whole topic should be broken down into several DIY threads, in order to answer specific topic questions, as the general topic is waaay too diverse. Here's how I break it down.
Barrel Prep
Solutions, Rusting, and Carding
Etching and Polishing
Fault Correction and use of Abrasives
Finishing and Polishing
It's tough to understand the intricacies of the process until you actually do it, make mistakes, and then come up with solutions. I'll certainly try to help answer any questions, and there is no better feeling than to produce a superior result you can be proud of.
It really helps if you're an anal perfectionist.
Regards
Ken
