In response to a recent comment I have provided the following layout for my pedal design for anyone interested.
I’m cheating on the pedal a bit and have no forward stop other than the actual potentiometer throw distance so there is the chance I could really do damage if I laid into a pedal. I had planned on adding stops at some point but just left it as is for now.
Here are some stats on the pedal layout
- Length: 11 5/8 inches
- Width: 3 1/2 inches
- Pivot Point: 3 3/4 inches from the heel of the pedal.
- The pin that holds the rack gear to the underside of the pedal is exactly 3 1/2 inches back from the toe.
- As far as placement of the mating gear to the potentiometer I basically placed it to meet the rack when the pedal was parallel with the deck. On my design this means the center point of the potentiometer is 1 1/4 inches from the underside of the pedal
- Back of pedal will rest on the deck in toe up position where the underside edge of the top is 2 1/8 inches above the deck
- In the toe down position the underside edge of the top stops at about 3/8 of an inch above the deck. A simple rubber footer would probably be an effective stop there.
Once you have everything assembled I would recommend sending the midi signal out to something like MIDIOX and testing the throw to find the zero point in the heel position.
