Keith,
I applaud your effort. I can see from your website some of your efforts:
http://oldemagics.com/slow_blue.htmI would suggest you get a copy of RH Angier, Firearm Blueing and Browning.
You will find a good bit of discussion on this topic in the FAQ

http://www.damascus-barrels.com/Finish_Restore.htmlYou may want to call Buck Hamlin or Dale Edmonds. I know Dale is willing to help.
Finally, please on your website, do not refer to damascus as wires. It only gives credence to the old myths. If it were, the resulting tubes would be unshootable. You are referring to the pattern, of which there were many.
