You should post your progress in the General Luthiery Thread. Save cluttering up this thread with feedback. But while I'm here, I originally didn't notice the smaller hole you have for the amptone labs rotary encoder, but I think it's a bit on the small side. I have fitted this on one of my guitars, and pretty sure it needed an 8mm diameter hole, like the other pots. The size you have looks around the size of the centre rotating shaft.
