Hello! I have just finished the SV1 kit, and I really enjoy it. A hardtail version would be cool!
To position the bridge you will need to do the same thing as fitting a telecaster through body bridge. The key thing Is to get the bridge to allow the strings to pass over the fretboard correctly, so both E strings run along the neck right. The other thing is to allow for correct intonation, the distance from the 12th fret to the saddles when compared with the distance from 12th to the nut. It is a little further to the bridge than the nut, but I'm sure that is covered in detail on his forum somewhere.
To drill the holes through the body you must use a drill press, and you will go from the front of the body to the back. You will need to drill slowly and go though the body gently else the wood can split on exit and mess up the back a bit.
I think it would be a great project!
