For this prototype I TIG welded the ends of some commercial crank arms to a custom built frame fit to mount in my rowing shell.

V0.2

I cut ends of pedal arms and TIG welded them onto an assembly that fits the foot stretcher. This allows the use of SPD pedals or any other variety of clip-in pedal. Because the whole pedal is used, there no longer are any unexpected forces against the mechanism. I have had this in my rowing shell since at least 2017 and it works well.

V0.1

• I used the guts from a Wellgo WPD-823 pedal and mounted them on a piece of aluminum. This bracket was mounted solidly, on contrast to a pedal that can rotate, which meant that a clip that was meant to not receive much torquing force was exposed to such force so it eventually broke.
