For over a year now I've been wanting to build a tall bike. Last summer I took a welding class and learned quite a bit, finishing the class by welding together two frames.
The picture below is my first mock up of the bike:
I later decided to cute a down tube from an old junker Marin frame I had sitting around to weld in between the two headtubes. This really stiffened up the frame a bit and gave the bike a more complete feel.
I began my summer industrial design studio with the idea of completing the frames that I welded together last fall.
I wanted the two frames to look as if they were one, although the seat tube angles obviously kill this, I wanted to put some bondo on the frames to smooth out the lines and make the frame look at clean as possible.
I've got a couple more projects in the works, including making wooden fenders for the bike, and also have wooden panes frozen in the triangles of the frame.
I'll keep posting pictures as the frame progresses.
Today I put another coat of primer on the frame and finished sanding down some of the filler I put on. The picture is hard to tell the shape of the frame, but once I put another coat of primer on it really started to take shape. It's still got some work but hopefully I'll have it finished by next Friday.
Below is picture of a fender bender I recently built, it still needs work but it's coming along nicely.
