Diarama Part Deux

Falling behind, sorry, still stuck on pictures from last week. BUT, here's where I'll shift gears and start showing the live ammunition shots as I'm working up Lori's real bike. First off, the drafting day. Basically drew out a full scale mock up of the actual bike, including chainstay schematics and then converted it all into machining instructions...here's the bottom bracket junction.



Then it was off to turn pencil lines into metal...here's the bottom bracket / seat tube junction jigged up and argon purging prior to welding.



Another view. The jig is pretty tricky to weld around, so we just do some little tack welds and then pull it out for the full business.



A view of the class with live bodies in it.



By the end of last week, I had Lori's front triangle cut down and ready to get cleaned up for fitting in the jig and eventual welding. I got that all done yesterday over the course of several hours, with only some minor trouble spots, so, this thing is becoming reality!



I'll post the actual bike in action shots tonight.

Rear triangle machining & welding today. Gotta get to class!
