Dual use pedal
Posted: Wed Feb 17, 2010 5:04 pm
I started on my pedal that will do 2 pulls today. I am using the same basic design as I used on my knee lever. The main difference is the center has a square hole so it it fixed with the actual pedal cross rod. It will then pull one of 2 other cross rods depending on the direction of the switch. I just grabbed some scrap and got the basic idea here . I will get a working one done soon .
For those who may not understand how it works without the rest of the parts being made , look below at the link , and the rest will be pretty much like the knee lever. The center has a square hole so it is fixed to the cross rod, then thrust washers on each side and a 1/2" outside diam. bushing with a square hole cut in it as well. The outer levers that will hook to the cross rods have a 1/2" hole in them so they can move independent of each other . Followed by another thrust washer and lock collar. Excuse the long set screw , it was handy and I didn't want to go to town .
