hi, i'm trying to assemble a parts guitar, but i'm having quite a few issues 1. the neck cavity is too big and the neck jiggles around, is this bad? how do i fix it? 2. how do i drill the retention screws for the tuners? i tried just using a phillips and stripped a screw. 3. the holes for the neck pocket don't line up with my warmoth neck, do i just drill more holes in the body?
