I recently completed my moxon vise. It is made of hard maple. I made a table top and drilled some 3/4″ holes where I can use Veritas bench pups to clamp stuff on top.
I bought an acme threaded rod and milled a grove for a flat wedge in the end. I bought the hand wheels from Wiberger, a local hardware store. www.wiberger.se They had made the wedge slot in the wheel already, then I drilled an axial hole and threaded it for the lock screw.
To get it rotating easy so that I can you give it a twist so that it rotated quite a few revolutions I made a support behind the actual acne flange nut that is screwed to the back of the front board. In the support I inserted a plastic acme nut to eliminate any drawer effect in the flange nut. The plastic guide nut I bought from Colly components.
The maple is finished with Danish oil.
It works quite well.
