This week I routed the control cavity and cut the cover. The cavity came out nice and only needs to be sanded smooth. The cover didn’t fit at first (did this on purpose) and needed some more sanding. It took me a while to get it to the right shape and finally it did fit. It’s flush with the body nicely and the fit is okay, but it was hard to get the space between cover and body equal at all places. Being a perfectionist I think it’s not very good, but after all I’m happy with it in a way.
I also have to think of a mechanism to attach the cover. Basically, I’ve got two options: screws or magnets. But I can deal with this later on.
