This is a photo of the work in progress. I built the torsion box table top out of 1/2"MDF and like Bart told me it is really heavy so I had to come up with some way to handle it by myself. I can slide it onto this moblile work stand that I bought from Northern Tool for $140. I had to add onto the top to get it high enough that I could use the foot pedel to raise it and also to level the top. You can see where I shimed between the work stand top and the wood. After I built the top I decided that I wanted a couple of Kreg plates installed so that I could use their hold downs so I had to cut out between the supports and fill those two sections with plywood and glue and then seal it up again. I threw together a couple of roller "things" that I could slip under each end of the table to roll it to a storage place. Now I can push it around with a couple of fingers.
This is basically the same picture except the torsion table is laminated and the plates are installed. The mobile base is at it's lowest adjustment.
The assembly table is ready to go to work. I can adjust it where the top is 17" above the floor level or 36" above the floor level or anywhere in between. This way I could also use it as an infeed or outfeed table. Now I can complete the assembly of a project and roll it into my temporary spray booth for a finish.
It is not totally stable but I think that is because the swivel casters are not double locking. I am planning on slipping a couple of vertical pieces in where the handle should go; Take a little weight off and lock the verticals in place. If that dosen't work I will come up with some leveling legs on the ends of the table itself. I also need to add a few handles to the table to make it easier to manipulate.
