I want to cut round clean-out doors in my birdhouses and wish
there was a hole saw with a very thin kerf, like a metal bandsaw
blade (.035" thick).

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.

I have/had sets like this, lite duty. Just measured some loose pieces, the
thinnest is .050, from Lennox, 1.5".
Also Starrett, and I think Blue Moly. I think I have seen Milwaukee hole
saws .050, as well.

You might try a place like Garrett Wade woodworking in NYC, or maybe
Constantines, who used to be in Bronx, NY, but is now in Florida, iirc.

Someone with a surface grinder and spin fixture should be able to thin these
down pretty quick. Poss. even a lathe, with a carbide tool. You'll proly
lose some kerf clearance, but for shallow cuts it shouldn't be a big
problem.
