So suppose I was rebuilding my workshop table that incorporates my table saw. Is building the top section as a torsion box style important if the underside is all modular cabinets like a kitchen?

Below is my current setup and the new layout will be very similar. The only difference was this current table was built on the cheap using 2×4&4×4’s sheeted with osb with a 1.5” mdf top. I plan on building the new base using mdf with each section as a small cabinet, so not sure if a torsion box style top would be needed. The other question is how skinny can I make a torsion box? I’m wondering if having a 1.5” top necessary vs a small torsion box underneath. Thanks in advance for advice!

I think a torsion box is the way to go if you need to have a flat surface and the supports for the table are relatively few and far between.

If your setup is going to be stationary and the space below the top is more-or-less filled with cabinets I don’t think a torsion box is really necessary. I would consider attaching the top to the cabinets with pocket hole screws every foot or so. Then, starting at the table saw top, work outward screwing down the top, shimming as necessary to keep it level.

A single sheet of plywood/mdf over a simple frame, as I did with my outfeed table, makes for a plenty flat surface.

Thanks for replies guys, here’s the framing below, I plan to add reinforcements as I build it, but the basic design is there, I imagine that should be strong enough to keep a relatively flat table (I hope)
