Here it is. It’s skinned with 1/2” MDF on each side and the top is 1/4” hardboard. The edges are wrapped with clear pine with a chamfered edge. The hardboard just sits inside the pine edging and is not fastened so I can replace it when it gets trashed. I had an extra hand with the glue-up of all the short pieces( 60 I think) and also with the skins. The table is at the same height as my Table saw( along with every other surface in my shop), allowing for support of sheet goods as they are sent through the TS. There is a spot for my compressor and a spot for a shop vac. I’m planning on running air line through the cabinets with hook-ups on the long sides. I’ll also run some power strips. The hardboard has a nice smooth surface but I may still coat it with something when I finish the edge.

This is really coming together well. Your top should be dead flat and it was an excellent idea to make it the same height as your table saw. It doesn’t look as if the bench is mobile so I assume that you are going to place it in proximity to your table saw?

Great idea and work. Thanks for sharing

The infeed side of my table saw is just out of the shot at the end of the new table. Stock can come off the new assembly table right into the saw. I’m not moving this thing. It’s heavy.

Great job Tony! I saw this on The Wood Whisperer as well and thought I’d like to build one. What was the hardest part of making/assembling the torsion box? Any tips you think we should know? I’m going to make one as soon as I’m done with the honeydo list. Guess that means I’ll never get to make one. ;)

You can go to and find a similar assembly table in a three part series entitled “Dead-Flat Assembly Table”. They have measured drawings, instuctions, pictures and video.

Great looking table – I see you even included dual toe kicks on it, leaving no stone unturned :-)).

Charlie – you don’t have space in your shop for this one (me either).

ok – i’m a newbie and curious what the purpose of the torsion box is vs. a solid (ex: 2 – 3/4” sheets of mdf) for a top … which could still allow for a hardboard top … please help me understand … i’m designing an assembly workbench as well as table saw outfeed … some insight here would be greatly appreciated … thanks

The purpose of a torsion box is for assembly reference. It is a strong, ridgid, DEAD-FLAT surface. For example, If your table saw’s surface was not exactly flat, it would be difficult to get accurate cuts. The torsion box assembly table allows for accurate glue-ups and assemblies as well as accurate reference for measurements. This works especially well with pieces with legs. Hope that helps.
