LIQFITS: Materials

After I asked for advice from some stainless steel engineers, it become clear that it indeed would be possible to construct the frame from seamless stainless steel tubes. The diameter of 22 mm and a wall-thickness of 1 mm seemed ideal. This combined with 8mm tubes to build a crossbar frame (like trusts) would be strong and light enough. I, personaly, don't like the fat tubes that are reguraly used in recumbents. To each his own.

After filling in my wishlist with everything I wanted and needed, I went to my bikedealer, and after some counseling, I ordered all parts.
The parts that couldn't be ordered were built by friendly companies: The derailleur-hangers, the bottom-bracket-shell, tubehead, and the V-brakes attachments.
After all parts arrived, I built a fullscale mockup to try to fit everything in.

On the picture to the left:
~ The water-cut derailleur-hangers (fine screwthread cut for the derailleur)
~ The machined bottom-bracket-shell. I choose for a completely clamped bottom bracket, so that I didn't need to cut any screw thread.
~ The tubehead, with two holes to hold the frame-tubes.
~The two V-brake connectors (machined and later finished by me, drilling holes and such).
