The piece I'm making is a sun with radiating sunbeams. The sun and
beams are a glue up of separate pieces of a variety of woods. I'm
gluing together the beams first and want to cut a precise round hole
in the middle for my disk "sun". The stock is about 3/4" and the sun
will be about 2 1/2" diameter. I'm trying to figure out to cut out a
precise round hole for the sun to fit perfectly into the beams. Any
ideas how to do this? Thanks, Bob O.
Maybe this could be done on a lathe or ShopSmith by mounting the piece on a
faceplate and doing some outboard turning. Many older (Delta?) lathes had
outboard mounting capabilities and the SS can easily reverse the whole
headstock if the piece is over 12" diameter. Seems to me lathe turning in this
way could lead to a very precisely sized hole with reasonable care. Just a
different approach.

You could use a 2-1/2" Forstner bit, with a very shallow cut on the
drill press for the hole. (assuming you're using veneer.)
Look for arch punches, usually used to punch holes in leather, to cut
out the sun. Available at McMaster-Carr & other fine metalworking
tools purveyors.

That's what I did about 10 years ago when I made a board (& box) for a
game called Wordsearch. I could not find another copy anywhere after
buying the original in Anchorage. It involved inlaying 64 contrasting
circles on a board.

Check out a circle cutting jig for the router, or as Luigi thought, a forstner
bit. Will you be cutting through the beams, also? If so, the you may want to
enter through the backside. Maybe! Tom
Work at your leisure!
Spur bit (like a forstner)
