I have to cut some dovetails into 1 1/2” thick red oak. The dovetails will be 2” deep. Don’t have band saw. Am reasonably proficient with hand saw in cutting dovetails in thinner stock. The pieces are the side rails on workbench I’m building. Will use back saw for job. Can re-file to rip profile on teeth. Any suggestions for how many tips per inch I’ll neesd?

I would not stray from 15tpi. But I would recommend a fairly steep rake angle (like 90 or a hair less) to spead things up.

9-12

I use a bowsaw for large dovetails with a refiled butcher saw blade. I
think it’s 11 TPI but it might be 9 or 10.

Most of the set is filed off on a stone. The saw has so little set it jams
in the kerf unless waxed. That’s the idea; it tracks like a dream.

I second 9-12. I would also lay the rake back a bit from nearly zero as mentioned, just going to be rough on the teeth and have a hell of a time starting it. I would put the rake at about 10-12 degrees.

Sorry about leaving out one important bit in my last post. Meant to say I would put the rake at 10-12 degrees at the toe and move to 4-6 degrees as you move towards the heel.

Neanderthal trumps me. That makes a hell of a lot of sense.
