Bell crank for gearchange - construction question
I'm about to make one and I'm wondering:
1. what's the thinnest sheet successfully used for a bell crank (i have some 3mm and 10mm ali kicking around)
2. did you find there is an optimum size (e.g bigger to allow multiple mounting points to experiment with sensitivity/feel of gearchange)
What lessons did you learn? Any info to speed up the process would be most appreciated.
Many thanks
Ben

Hi Ben
think I have several lying around the unit from old projects - you are more than welcome to them - doesnt really shed light on the construction but
might save you time - i think one is off a Westy
regards
Andy

Cheers Andy. That's very good of you. I'll send you a U2U in a second.

Mine is made from 5mm steel. I found the important thing was stiffness of all the components. Any flex in the bell crank, rods or pivot and the
gearchange isn't good.
