This is what I needed to knock loose a memory of something I saw "somewhere" -
maybe an old best of fine woodworking. If you can get a reasonably straight
starter hole, say 3/8 in diameter, cut a kerf in a piece of slightly under 3/8th
dowel so that it will cover the guide point of a spade bit, then drill with that
assembly (there may have been a drop or two of super glue in there. Since the
guide point of the spade bit is now sheathed, it pretty much has to follow the
3/8ths guide hole. At least, that's how I understood the theory.
(I have never tried this myself, so try this out on something from your scrap
bin before you trash something you've put a zillion hours of work into and hate
