The house I purchased has a workshop table with a vise attached to it.
The vise is missing the "do-hickeys" that lock it into place. When
you try to use it, the vise wiggles and turns. How can I find
replacement "do-hickeys" or create a workaround to lock the vise in
place?
thanks,

You can't. That's why they sold the house. Now you're stuck with it
until you sell the house.
