Topic tags/keywords: question

I am planing on building a new assembly table for my shop and getting rid of the old kitchen table I am using now. I have been doing a lot of looking around and research on different assembly table and not really set one or another. My main question is what are the benefits of a torsion box top compared to just a basic assembly table top…. and feedback would be awesome!

Perfectly flat, stable dimensionally, rigid and extremely strong for the money outlay.

A reference point springs to mind like when you level 4 legs

A torsion box is great if you need a near flat surface for assembling, but I would not use it as a workbench top where hammering or drilling is to be done.

The strength of a torsion box is absolutely amazing. Mine is about 50” square, about 10 years old, and is slated to be replaced this year. I built it out of MDF, and over the years it’s pitted and peeled with different jobs I’ve done on it. What I like most is that’s its a perfectly flat surface that I can clamp things to. So if a drawer box racks just a little, I clamp it to the assembly table to hold it flat until the glue dries (sometimes a little hard to do on a 50” table). My next one will be rectangular, maybe 36×72 or something. There is a downside. With mine, picture a 50” square table that’s 6” thick. Moving it is kind of a headache. Since I used MDF for both skins (I used 1/2” ply for the web) it isn’t real light either. Someone else mentioned it: these aren’t for hammering/pounding/or some other stuff you might do on a hardwood bench, but they can be beat for assembling your stuff.
