BRC PIPING
If you are rebuilding a BRC tub, one of the difficult bits will be the key-holed shaped piping that goes all around the perimeter of the tub/cowl. Here is how Don Shook of Butler PA does it.
Materials needed
Hydraulic tubing 1" 0.side x 7/8 1-diameter length as
needed
1/4 " pipe length as needed
I sued 4 pieces of "piping"
#1 from drivers center of door opening to center of passenger
door
#2 center of passenger door to passenger rear corner (mitered
at corners)
#3 center of drivers door to driver rear corner (mitered
at corners)
#4 across rear back (mitered at corners)
3" longer than needed so you will have sufficient to trim and align. Do all shaping and bending after piping is made with 1/4 pipe left in side. Do all bending (heating is necessary) by shaping to body curves. After bending and curving is very close to fitting use a reciprocating saw with blade going into slot after final bench in vise.
Sample #2 after being split it enters here ready to place on B .. by spot welding or counter sunk riveting on both sides of piping. (I like riveting and grinding heads because you are assured a good fastening. I used 1/8" counter sink rivets and peened into counter sink hole grind all rivets flush with piping surface.
I bent all my piping with a 5" bench vise.
1" bend your length of tubing a little at a time until it is about egg shape or 1/4" pipe enters freely put 1/4" pipe in make sure it fits to the top side it will be necessary to tap down here to make sure tubing is tight against pipe while you keep squeezing with vise always keep saws of vise close to 1/4" pipe
It is best to use or make a set of smooth vise jaws so you do not mar surface of piping (I made my smooth vise jaws from 1/4" stock.)
