the copper and brass are fittings from either plumbing or welding fixtures. a lot of the stuff is too big so it is turned on the lathe, cut filed, etc for a fit. for instance on the fuel strainer thats 1" copper pipe with an end cap, and a 1" x 1 1/4 " adapter. the fittings were cut so there is only about 20% left, then assembled with solder. the fitting that goes into the carb is an old valve guide soldered to a 90* compression fitting. the top of the fuel filter is actually 3 pieces of brass soldered together (10 pieces total to build the whole strainer)
the copper exhaust... same deal, just bigger parts. well... I had to cut & solder strips for the brackets and build a tool to flair the exhaust ports, but it's all plumbing stuff. actually, some of the exhaust is copper braze not solder (special rod).
the turn signals were made from turn of the century chandelier parts along with some antique aircraft parts and some Salvation Army glass candle holders. the holders were cut down and then stained.
the tin work on the tank & cowl is welding and riveting. paint is... painting. all that is just work & knowing how to fix your mistakes
dunno... anything somebody really interested in I could prolly do a blow by blow. thanks for the interest
