Pedal Roller Board
The purpose of the pedal roller board is to transfer the action from the
pedal board to the pedal windchest. The order of the pedal board is chromatically ascending from left
to right. The order of the pedal windchest is as follows:
The following image shows the layout of the pedal roller board. The pipes shown are CC-C#.
Pipes CCC-BBB and D-F will be mounted off of the windchest.
For the rollers, I used aluminum tubing with a .500" OD and a .375" ID. Here's a photo of the end of
a roller. I plugged the end with a wood dowel and used a Ø.062" dowel pin as the axel.
The roller arms are attached with a screw and epoxy.
Here's a photo of some of the rollers waiting for the epoxy to cure:
The roller stands are just blocks of wood with a clearance hole for the roller axel. They are held
in place with a screw that comes up from the bottom of the roller board. I placed a felt disc
between the roller and roller stand to prevent hard surfaces from touching and making noise.
Here's what a roller stand looks like assembled:
The aluminum tubing only came in 3 foot lengths but seven of the rollers needed to be longer than
3 feet so I spliced two pieces together. I inserted a solid piece of Ø.375" aluminum half way into
each piece of tubing. Then I drilled and installed three Ø.062" roll pins in each side. This method
made for a slop free joint that kept the two pieces very straight.
Here's a photo of the CC# roller:
Here are some photos of the complete roller board. The notches along the front side are for
the squares that the pedal board will connect to. The open space on the back side is for the pedal
windchest to sit on.
