Build Mufflers

Added flexibility and accesssibility is created by using individual cylindrical mufflers, at about $10 in parts per muffler, compared to a single muffler (more space constraints and $200 cost)


 * Cut inner tube - 6.5"
 * Cut outer tube - 8"
 * Secure 8 close nips, 1”
 * Secure 8 elbows, 1”
 * Cut 2 rings – flange and end piece of large tube
 * Grind and ream rings
 * Prepare 1 washer – 1/2” - for closing inner tube
 * Prepare 1 closure of washer
 * Mark pattern for muffler flange
 * Torch muffler flange, use #1 torch head
 * Weld muffler assembly starting with muffler flange - threaded into elbow to protect threads from welding
 * Weld inner tube to second close nip
 * Weld inner tube flange
 * Weld closure of inner tube, close off inner tube by welding
 * Weld outer tube to flange, then close off outer tube
 * Attach muffler to engine, with an allan-head 5/16"x3/4" bolt for the inner bolt (because of inaccessibility), and a regular hex head bolt to outer flange hole, with metal lock washers on both bolts
