Bulkhead angle... Here we have the curved angle that joins the sides and coal aprons to the front bulkheads. Curving angle is always a fiddle. Here it is being formed with the help of a steel die. This same die was used to form the ribs. First you must anneal the brass by heating it to a dull red heat and then quenching in cold water. Then onto the die and start forming it with a rawhide mallet. When you work the brass it will begin to harden. These parts were annealed three times before they snuggled up to the die the way I wanted. Then they went into the acid pot to remove the oxides that formed in the annealing process. Lastly they were polished up with some red Scotch Brite. Then begins the drilling and fitting up with Clecos. After you get all the holes drilled you must disassemble the parts, de bur and clean between them. If you don't, you will get chips between the pieces and when you rivet them you will have lumpy sheet metal. {BACK} {HOME} {A&C SHOPS} {BERKSHIRE} {AMERICANS} {No. 9} {CARS} {JEWELRY} {CONTACT} copyright © 2004-2006, Jack Bodenmann, all rights reserved.
