Thanks Dusty!

This was just what I needed to get me back to my torsion box project. It's been sitting in the shop for a long time now and I'm working on a TV Stand/Entertainment Center that needs to be dead squard and flat. So I'm going to set to finishing the torsion box first.

After looking at my junk piled up on the torsion box project I've decided to just scrap it and start over and do it right. (Isn't it amazing how every horizontal surface seems to attract lots of "stuff" to cover it up?) I think I'll build this one in the garage so I'll have an incentive to get it done. My dear wife doesn't like having her van out in the hot sun so I have to work fast before she gets upset! lol

Thanks again for your post. I've bookmarked the link so I can be inspired some more if needed in the next week or so.

That torsion box looks great. My solution for having a dead flat work table was solved many years ago. I purchased a solid core 80"X48"X1-3/4" birch door. I built a wall cabinet to match the door and mounted the door with a continuous hinge to the bottom of the cabinet. The (very heavy) door pulls down and sits on two 3"X3" legs that are hinged to it. It is a little awkward and means that I have to actually get up on the table to access part of the cabinet, but it is perfectly flat.

I think you could have used a hollow core door as most of them are built just like torsion boxes. Only they have a either low cost wood or fibre board as the webbing. I guess if you put something heavy enough on one you could dent it but if you first covered the door with 1/2" ply and/or fibre board I would think it would basically be a the same.

EdThat is a good thought, Ed, but the solid core door was "surplus" and I did my dad a favor, by buying it from him. Also, your suggestion for additional thickness aside, as a kid I put my foot through enough hollow core doors to make me leery of them. Do knot forget, I have to climb up on it occasionally. :rolleyes:

edit: BTW, that torsion box can knot be all that light; it has almost three full sheets of 1/2" MDF built into it!

First time posting. My assy. table is a hollow core door cut down to 5' long (48" wide) so I can lift it onto two saw horses. I'd like to see someone try to kick a hole in it. I got it years ago when one of the local hospitals remodeled and replaced all the room patient doors. It has 2x6 rail & stiles and the covering is 1/2" plywood. It is a beast.

I have seen a lot of doors like that. Many also have a metal or dry wall fire break in them, as required by fire codes. I would think that would be the perfect torsion box and most are being thrown out as new fire code almost always specifies solid core doors or steel.

Sounds like a good table though!

edit: Just read Ed's reply. If those are available as "junK", they sure could be repurposed by woodworkers.
