    Drilling perpendicular holes where the drill press won't reach.

    Not sure if this is the right place to post, but I had a problem, sort of worked it out, and thought I'd post it here to see if it's any help to anyone else...

    I need to drill two near perfect holes in the top of an ES style body. this would generally be a job for a drill press. Unfortunately, drill presses have limited reach, and mine has a reach that is about 1/2" too short to drill the holes I need.

    In theory you could use a drill guide to make the holes. These are available from many places and seem to run between $20 and $40 US.

    In practice, my drill guide has been a pain to use. It drills perpendicular holes, but it's easy to get them slightly off center because the bass of the guide is not very stable. To make matters worse, the surface fo an ES body is curved, so I can't put a guide on top of it to drill the holes anyway.

    So, I decided to build a stable platform for the drill guide that I could put over the body. I took an old shelf I had lying around, but any flat piece of wood will do. I cut a couple of pieces of 2" thick scrap lumber so that they were perfectly flat on both the top an bottom, and about 3.5" tall. This formed a stable base. I screwed the drill guide down to the platform to maximize stability. I wanted the drill close to one edge of the piece of shelving, so I used a hole saw to drill a 3" hole for the drill bit to go through. you could do this with a jig saw, or drill a smaller hole, but the big hole, and being close to the edge of the shelf, gives a better view of what you are drilling into.

    Here's a pic of the whole thing drilling into my test piece of wood.

    ...Continuing from last post...

    I used a brad point drill bit to so that I could align the point in the exact center of where I wanted the hole to be. Here's what a brad point looks like:

    Have not tried it on the ES body yet, but it worked pretty well on my test piece. The tolerance on this bridge is very small, so I had to get it right...and it seems to have worked...

    Great solution! I have a similar drill press contraption and will be building one of these jigs for squarer hole drilling.

    And this is why I love this forum! I had just gone and bought one of those there drilling contraptions, for doing Trem post holes and discovered the same sort of conundrum you had. I was about to go and seek advice for a frame or mount for it and POW up pops this thread! Problem sorted. Great Stuff Fender!

    I've seen one of these drill guides that had adjustable feet on to take up the difference. Now I need to find one now.Great job Fender3x.

    Also saw a bench drill extension piece ages ago and have as of yet been unable to find it again. I knew I should of bought it at the time. This is someone's idea for extending a drills depth front to back. Using cast pipes.
