WOOOOW :-)
Great pedals. I must say I registered to this forum to comment on this!
I built my own pedals a while ago on woodworking CNC with Fundermax Maxcompact material - similar to bakelite. Big mistake was not doing reasearch prior doing it :-) I tried to make it easy project. Later I adopted Simed pedals style centering.
If anyone is intrested in my design it's no good becouse :
1. sliding rudder need greasing ...under a desk in a dusty enviroment it's a bad idea. I added 4x wheels on each pedal later but its too much friction for me, specialy becouse pedals are high above slider which contribute to forces causing friction.
2. CAM centering is better than simped's, simply to adopt different strenght along the curve and nicer center feel
3. I used 100N pneumatic compression cylinder for brakes. Cylinder is a standard part in furniture industry and quite affordable - 5 Eur, but it's lenght forced me to use it under this angle - and it's too weak. Under a more narrow angle between pedals it would be more suitable as it would use more compresive lenght of cylinder...so it's better to use spring or smaller cylinder like Vo101mmaister did.
To Vo101mmaister:
I am going to make new design, similar to yours but using cheaper materials (bakelite-alike 10mm board,springs,ballbearings). If you are willing to share your drawings it would speed me up a lot :-). I'm most intrested in centering cam and spring desing...if it's working for you why not use same dimensions and CAM curve,bearing diameter.
Also what's your distance - center to center between pedals, and how much travel? I used 25 degree travel angle, 350mm centre to centre, 310x120mm foot support ( bit long, everything else is ok for my legs :-).
Also you didn't comment on which controler board and sensors/pots did you go for and how happy are you with those ?
Thank you in forward and regards to all
