I had chosen relatively thick walled aluminium tubing to make it easier to weld the joints without blowing through the tube ends. The downside to thick walled tubing was that I found it cracked if I bent it at two tight an angle on our pneumatic pipe bender. I tried to anneal the pipe before bending to see if I could reduce the cracking issue but found that it didn't make much difference, since I've never tried this process before it may have been that I needed to experiment further with heating and cooling, but I found that I could just about get away with bending the tubing as much as I needed to form the frame without cracking the tubing.

All the coping joints were made by hand with an angle grinder which produced acceptable results and then TIG welded.

The frame is designed to be easily removable from the bike if it is not required for use in the summer. Two 8mm stainless steel bolts hold the frame to the subframe, which is held to the front by four 6mm stainless steel studs, and at the back to an aluminium subframe made of l-shaped extrusion bolted with more 6mm stainless steel studs and nyloc stainless steel bolts.
