So, I built a board using pallet wood:
First, we cut the planks to size, and fit them to get an idea of how the finished product would look
Then we sloped the sides so the board stands at an angle.
We then planed them to ensure the planks are exact carbon copies of each other.
Using glue and screws we attached the horizontal planks to the feet/side planks
Once they were all attached, we sanded off all the rough edges, splinters and nibbly bits, then applied a wood stain.
Whic gave me this as a finished product.
After this, I applied strips of Velcro for attaching the pedals, and then the pedals themselves.
