So... technically, I met my goal.
Summer is long gone and we're well into December, but I have a roller!
I got my tires, tubes, and rim strips and couldn't wait to put them on. I probably should've been patient and finished the rear triangle, but I was too itchy to take this thing off the table and push it around the garage making engine revving noises...
The rear triangle is all welded, but I still need to add the smooth bronze fillets, and "cap" the tubing ends. Plus all the filing and sanding that goes with creating the smooth transitions from one tube to the next. There's probably a week's worth of hand-work waiting for me. Of course, the whole rear end needs to be taken apart AGAIN to do this... (all those engine revving sounds were totally worth it!)
I'm totally excited to keep going, and really proud of my little creation. The 4 next things on my list of things to do will be: finish the fillets/bronzework on the rear triangle, fab up a rear stand, add the steering-stop, and make the foot peg brackets. Then the brakes will need plumbing, a seat would be nice, some way to shift the gears, something to hold gas...
But in the mean time... anyone interested in a slightly-used build table?
