I built a jig to make finger joints on my router table. I'm using a
1/2" router bit and spacing the fingers 1/2" apart. It worked well.
Probably too well. I had to dry join the wood with a rubber mallet and
a vise. The fit is extremely tight. I suspect it is way too tight to
glue. It seems to me that I'd want a couple thousands of an inch gap
between the fingers to accommodate the glue. What's a good way to
accomplish this? Should I just sand the fingers before joining?

I use extended set glue on overly tight joints. It is thinner.

If you have more than one bit you might try another; it might be a little
wider.
