I want to cut round clean-out doors in my birdhouses and wish

All the hole saws I can buy have about .100" kerfs, which is too
much to "fudge". Cut with a band saw works well, but, it's not a
central hole.

Even have the idea to try to make one from a 1 1/16" wide metal
band saw I have... I'd gently feed it in a drill press.


What's wrong with a Forstner bit?

I think that he wants to use the plug from the hole as the door,
so he wants a minimum kerf. Something rather difficult to do with wood,
I think.

*I* would use the Forstner bit, and turn a plug to fit from some
of the scrap left over from making the birdhouse itself.

They come in sizes to fit most birds, and as long as you back the bit that
will be the birdhouse with some scrap they make weally nice holes.

Agreed -- but I think that he does not want the birds to go
through these doors -- instead he wants t be able to remove the door
after the bird season is over, so he can clean it out for next year's
tenants.

Enjoy,
