I'm modifying an electric guitar body made of basswood, which is considered a "soft hardwood."
I need to elongate four holes that pass through 1" of wood. They are 3/16" in diameter, and I need to convert them to 3/16 x 3/8" slots.
I would employ a 3/16" straight router bit, but cannot find one online or locally with a 1" or greater depth of cut, and budget constraints eliminate any expensive options.
Unless you can suggest a better method, I'm stuck drilling two overlapping holes next to each existing 3/16" hole, for a final slot length of 3/8". I think a Forstner bit would work, but my smallest is 1/4".
Assuming I can clamp the guitar body to my drill press table, I'm wondering if a brad point bit would hold true better than a typical twist drill.
Thanks
