Decided to have a go at making something similar, so I took the basic idea and adapted the sizes to suit the Carter style knee levers. I wanted to bolt them on from the back so decided to use Aluminium rectangular tube instead of Aluminium channel. I found some 25mm X 16mm tube which was almost a perfect fit for the width of the Carter knee lever and also bought a piece of 2" X 1/8th" Aluminium flat bar for the paddles. I didn't like the idea of using rivets as it would be difficult to get the inside of the channel flush onto the knee lever, so I used JB Weld epoxy to glue the channel to the plate.
I have 5 knee levers inc. a vertical, so decided to make paddles for all five. The 4 horizontal paddles @ 120mm x 2" and the vertical @ 100mm x 2". (forgive my mixture of metric and imperial sizes!).
Took photos of the build and thought I'd share the results with you all here. I made a trial paddle first, so the photos show the other 4 being built.
