thread adaptor

Greetings! my first post, I need help please.
I have a sort of custom desk / art project going on and I have a need for a unique thread adaptor: 3/4" NPT straight female, to, 3/8" Unified coarse thread female. I can't find it, has anyone ever heard of it or knows where to get something like that?
Any help is huge!
Thanks!

Got a picture of what your trying to make work.
There is no such thing as a pipe to machine thread adaptor.
May get away with drilling and tapping a pipe cap.

black iron pipe would be ideal, but I could make galvanized work or something similar...

That's a tall order. Are you trying to make some legs for a table out of 1/2" pipe and fittings?

If so, can you attach a pipe flange to bottom surface of table and abandon threaded rod?

Not a problem around my shop. I would just braze weld a 3/8" nut into the 3/4" pipe adapter and be through with it. If it will not be seriously loaded then JB weld would do the trick. Need lots of 3/8" NC threads, use a coupling nut. Available at any good hardware store.

OK that's nice but what is it your trying to do?
A bell reducer is useless for what your trying to do.
Making adjustable feet?
