Good day
I came up with something like in the picture that is good for "Cabinet router table".
All the parts can be made of wood.
The "Round nut" is one like used in the "Jorgensen" screw clamps.
During the lifting (i.e., rotating the threaded rod), the lifting bar (this one with the "Round nut") will "shorten". That's the reason that the lifting bar is slotted at the right side and can move left/right on the bolt (the "view from above" detail).
The "Lower support" is just a block of hard wood with hole at the size of the threaded rod with a piece of metal inserted in the hole to prevent the "eating" of the wood.
The "Upper support" is also a block of hard wood with a large hole to enable a socket to be pushed in to rotate the "Double nut" and, a small hole at the size of the threaded rod.
The "Plunger" is made of round stick and slids up/down in mating hole in the "Cross beam".
Bad idea, please go here
