Finally got my Scope

Some highly polished hammers of varying sizes, several mandrels, a torch, and lots of patience mixed with a wee bit of mad abandon will be your most important tools. Be sure to have the tube as clean and shiny as possible before the serious work starts.

The art of localized shrinking will probably be a handy skill as well. Mostly it's old timey auto body work on a very small scale.

One of my favorite non-aircraft sheet metal repair books is The Key to Metal Bumping by Frank T. Sargent. Don't know if it's readily available: Mine dates to 1953. Old Fairmount Tools publication. (Wonderful hammers they made!)
