I finally made a torsion box table! I have been wanting one of these since I watch Norm Abrams make one many many years ago. I want to thank all my fellow LumberJocks who have posted their torsion boxes on this site. I gleaned a lot of valuable information from you guys and I want to thank you for that!
Lots of time was spent build this project I had no idea how involved making one was going to be. Norm made his in a 1/2 and hour ;-) #1 picture is the finished table. I used 2”x2” glued up for the legs. I have sheet of 1/8” hardboard as an insert for the top. I can replace the top cheaply and quickly using the hardboard.

#2 picture is what the torsion table has replaced. The sawhorses and layers of plywood were just a little too unstable for assembly work ;-D

#3 picture is my son helping me glue up the inside grid before we place the 1/2 MDF top skin on.

#4 picture is the attachment cleat I made to affix the top to the legs. I found out later not to use the long grain as the tongue so I made another set using the endgrain with much better results.

#5 picture is what I was after! A dead flat surface that I can lever!!! Great moment for me when I placed the level on the table as saw no LIGHT under it!!

#6 picture showing all the pre-drilled screws I placed in both skins.

I used MDF for most of the table components, 3/4” perimeter boards with 1/2” for the grids and top and bottom skins. When I made the outside trim board I made it 1/8” taller to accommodate the replaceable 1/8” hardboard top.

All in all a great project, learned a few new techniques and now I have a great work surface that will last me a long long time!

I have one more torsion table to build, this one will be used as an outfeed table for the table-saw! WHOO-HOO looking forward to that one!

Thanks for looking, let me know what you think.

definitely on my to-do list, #57 !
question: people keep saying the top hardboard is replaceable top skin. but yet, it’s either glued down or screwed down or both. how does one replace it later on?

Holbs, my hardboard is not glued or fastened to the table. When I trimmed the table I allowed for 1/8” on top to accept the 1/8” hardboard flush to the top. When I need to change the top I just lift out the worn board and insert a new one.

Another one that’ll stay flat. Very nice.
