I am trying to finally assemble my latest pine body tele project and it looks like I may have a problem. This is a body made from 75 year old pine flooring and I drilled the access holes for the wires between cavaties a little small and a little high. Not to small for feeding the wires, but too small to have any hope of installing any copper foil in them. They are also a bit too high that I would be worried about getting too close to the face of the guitar if I tried to drill them larger. So, instead of being able to install foil with a pencil like I normally do, I am stuck. I have noticed over the years that Fender isn't applying shielding paint in all cases with their bodies anymore so it begs the question of is it really necessay to shield? Would I be better off using the shielding paint? After all the work put into this body with the assembly, sanding, routing, finishing, etc. I hate to end up failing to get it right, so what are my options here?
