    Time to finish off the guitar, job basically done, just add pickguard screws, strap buttons, String trees and Machine heads. EASY!!
    What can go wrong, drill a pilot hole and screw that sucker in, right?
    WRONG!!!! Stuff up an otherwise flawless Guitar Build :mad::mad::mad:

    This is embarrassing, but I now qualify for some award for snapping off small screws in bodies and necks!!!!:(

    And I've read the articles on Stew Mac and others on pilot hole sizing, I try to be careful, so why do I still get 'em wrong????

    What trick do you use to size small pilot holes for those String trees and machine head screws especially?

    And how do you go about drilling a screw out with minimal damage like on a natural wood peg head where any oversize hole from preying the leftovers out will be visible?

    I use a drill index measurement plate to measure the screw diameter and then use a pilot bit a little smaller. Then the screw gets some wax on the threads. A new phillips screwdriver the correct size helps too.

    You can take a piece of brass tubing and file teeth in it. This saws around the screw remnant and then you bust it out. Replace the wood with new face grain plug. Wood end grain doesn't hold screws so well.

    When in doubt I install a stainless screw, remove, then install the screw I want.

    ^^This.. I've never snapped a screw even using cheap Chinese tuners. They go in like butter. I do the same as Marty and use a guide.
