What that super clean new bench vise looks like in a commercial wood carvers shop in Barcelona Spain.
Clearly it is a tool that is very useful on a bench. The threaded rod is available for sale to enable you to make your own vise, or you can buy the gear and make your own threaded wooden doweling.
I have the threaded rod, and made a vise years ago but it wasn't very good. Actually the vise was about as good as my wood work skills at the time. Now...it is time to make another vise using new skills and better tools and materials.
