Step 2: Weld the sprockets

Most people would probably say "ahh, nevermind" at this step, but it's the only welding part. This is important to get straight an centered. I tried not to over-weld and warp things from too much heat. Then I cleaned up the weld splatter with a die grinder.
Also once everything was aligned, I put a spot weld on the treadmill motor shaft to keep the flywheel from unscrewing, it's not the usual lefty loosey, it is righty loosey here.
