xRickx Posted February 1, 2008 Report Share Posted February 1, 2008 i have a custom Warmoth precision bass. the problem with ordering like that is they don't drill ANYTHING except the bridge holes and thats ONLY because i ordered the bridge with it.. so, the wood is already painted and poly'ed.. got any tips as to how to go about drilling pilot holes for the pickguard without badly cracking the coat of poly?

al heeley Posted February 1, 2008 Report Share Posted February 1, 2008 masking tape to stop the drill bit skidding, prick the hole first with a very sharp bradall. make sure your drill bits are really sharp. Quote Link to comment Share on other sites More sharing options...

avengers63 Posted February 1, 2008 Report Share Posted February 1, 2008 and start with the drill running backwards if using a handdrill Even better if the hand drill's trigger can work as a throttle. Do it backwards slowly at first. Get through the finish before going into the wood. If you go through the finish too quickly, friction might scorch it. I don't think the burns would ever come out, so a re-touch would be necessary. Good luck! Quote Link to comment Share on other sites More sharing options...
xRickx Posted February 1, 2008 Author Report Share Posted February 1, 2008 well the pilot holes for the pick guard screws are going to be so tiny, i wonder if it would even burn.. plus, if it does, it's going to be covered by a pick guard ANYHOW.. i was just concerned about the finish cracking when i drilled, thats all so basically you're all saying to just be very careful when getting through the poly, and then drill the wood normally, right?

doug Posted February 1, 2008 Report Share Posted February 1, 2008 It's already been noted, but I can't help but stress how important good sharp bits are! Start with a small hole and go larger. Also, use a pilot bit to chamfer the holes BEFORE putting screws in. It's more likely that the screw will damage the finish than the bit. It's also helpful to make the start of the hole the same size as the screw so the threads don't dig in right there. -Doug Quote Link to comment Share on other sites More sharing options...

Mattia Posted February 2, 2008 Report Share Posted February 2, 2008 What all these guys said, but I also put some masking tape on the spot to be drilled, and drill through it. Makes marking the holes a lot easier as well. Quote Link to comment Share on other sites More sharing options...

I would do this with a brad point bit with outer points. http://www.leevalley.com/wood/page.aspx?c=...cat=1,180,42240 Edited February 2, 2008 by guitar2005 Quote Link to comment Share on other sites More sharing options...
Prostheta Posted February 2, 2008 Report Share Posted February 2, 2008 Those lip-and-spur bits look good for starting the hole using the "normal" direction for sure. Quote Link to comment Share on other sites More sharing options...
PTU 7's. Posted February 2, 2008 Report Share Posted February 2, 2008 Try to use tape, and start really slowly. But don't give too much care, the bridge will cover those holes = Quote Link to comment Share on other sites More sharing options...
