There should be all you need to know about springs in the archives, the
most brillaint idea I came across was someone cut some pvc pipe into strips
and made a circlip type spring, cheap as chips and very effective. I used
dress makers pins and just pinned everything in place, a bit messy and gooi,
you know, the pins with the plastic bubble on top. ( get good quality ones,
even humble pins have quality control, otherwise the plastic bubble comes
off and you are staring at a pin sticking up through your thumb ). If ever I
did it again, I would pre glue slightly oversize gussets to the cross
members, cut to fit and glue. A lot of people don't think this is a good
idea, someone told me the curve of the fuse will not match the gusset, but
if you go into the maths of it all and differentiate and limiting theory,
the section of the curve is so small it would approximate a straight line
anyway. I tried this on a test peice and it seemed to work OK, but I have
never done it on the real thing, so its uncharted territory. For the side
frames, I used a small block placed close to the gusset, sqeezed together
the top of a wooden clothes peg, and fitted it upside down in the gap.
