The Schaeffer parts arrived yesterday, and as usual they look fantastic. I love the customer relations at Schaeffer, they call me whenever there is a problem with my drawings and sorts things out in minutes instead of emailing me. This time they worried that the perspex would break apart, but as this was my intention anyway, it turned out fine.
I did however mess up the rotary encoder brackets slightly, the square hole is supposed to go on the other side of the pot. I might have to re-order them later. :-(
Pics will be up shortly.
