Bending Metal and Making Sparks

With our newly-modified exhaust from Cycleboyz, we needed to fab a bracket in order to mount it to the frame.  This would have to be a custom piece, and we'd also have to start from scratch.  These things always start with some eyeball engineering, a lot of staring and figuring, and finally a sharpie marker to mark the first bend.

While that project got underway, we went back after the electrical system, specifically wiring up some proper turn signals.



Battery first...  Once that was hooked up we needed to figure out why only 3 out of the 4 turn signals were working.  We were able to have a chat about positive wires, negative wires, currents, and shorts (the electrical kind, not summer wear!)

Meanwhile, on the exhaust front it was a case of measure, mark, bend a bit, measure again, twist, tweak, tap, hammer, etc, etc.....  The end result was a bracket that had 2 90+ degree bends in it... sorta like an "N" on its side, but not as sharp a bend.  With curves like that, we are hoping steel will do a better job and be more durable... bends like that tend to weaken aluminum to the point where it cracks and fails.

More electrickery... the boys got a chance to learn how to use a new tool... a spring-loaded wire stripper.  We'll need to lengthen some wires and of course add some ends to them, but we at long last finally found out where our problem was.  All 4 signals work as they should, with a hearty "click" from the signal relay.

Hammertime!

Yes, we do get to use some neat, delicate tools that do their job with finesse, and other times, well, we need to bash some metal around a bit, too...

Next step, some proper hardware and we might just start it up to see if it runs!
