Intrigued.....
I am making a workbench, that will live on my balcony. It will be primarily used for wood working. I have been thinking from the beginning that I would like a vice on my workbench, but the outdoor location means that any off the shelf, unmodified vice isn't going to work.
Then I noticed a vice screw on
https://fine-tools.com/ which listed a 24x5 thread... The pictures showed a trapezoid thread. 24 x 5mm trapezoid thread is a standard metric thread... Maybe I could get a stainless steel nut for the screw...
Well I couldn't find a suitable nut in stainless, but I was able to find one in bronze. Studying the materials datasheet showed that the bronze has reasonable corrosion resistance. Let's see if that works.
The nut alone cost more than the vice screw... then I got stung for €21 in import fees...
It's a beefy lump of bronze. Very beautifully machined...
Today a package arrived from Germany, with my Czechia made vice screw. I opened it, and with breath held, tried to fit the nut to the thread.
It works!
I have a Bronze nut, that fits the vice screw assembly! My plan is that the bronze nut is permanently attached to the work bench, then the screw and chop can be removed, and stored indoors.
This was quite a gamble, as well as the nut, I had also ordered the 32mm and 25mm auger drill bits to go with it. If it hadn't fitted I could have ended up with €50+ euro of nut I couldn't use, and two drill bits I didn't strictly need. But it fits!
The vice will be a leg vice.
