Could I impose and get some measurements of the cam and it's mechanism (bolt and bar setup). I am not sure what size to make things and I would like to do something similar if that ok?

cheers

Hello Barra,

Of course, you can do that. I give you measurements tommorow.

Cam profile and mechanism:

My suggestion:

- axle d2 must be thicker, i use 5 mm and is to soft (small deflection)

With this construction left side of cam must be more flat than right. But i not check yet (i can not use my left hand after accident). Something like on this drawing:

Much appreciated Kristof

Kristof I tried your suggested profile but on mine I found that it seemed to bind with the roller moving along the left side of cam. It started getting quite hard to push just short of half distance. I did another profile with even more slope to left side and got almost the same reaction. So I decided to file from when binding started. I ended up with a cam as in picture below. I just keep filing and re-assemble and try, then back to file again. As you can see I only shaped 1 side and the feel when pushing both ways is almost the same. I could maybe take a very small file to the last 6mm of the right side as it is a bit tight the last few mm.
