This is my new tablesaw built from 5/8” MDF in a Torsion Box design. It is 72” x 72” x 4”and has built in cabinets for my DeWalt Planer and Delta Joiner for easy access. The table is covered in Formica for a nice smooth surface. The saw sits on a 3/4” plywood platform that has 4x jacking bolts (one in each corner) for leveling and locking in place. It is insulated so that all airflow comes through the plate or front of the saw cabinet to sweep dust to the DC port. The ShopFox aftermarket fence is bolted to the table and has through-bolts for the Cast Iron saw surface to lock it in place once the saw is leveled. There is a dust collection port that has a variable damper (use the white hanger to open/shut) to allow the saw dust collection to be turned off during router table use. The router table uses a Rockler router lift kit and the backside of the tablesaw fence. Another plus – it houses a refrigerator (to the right of the plug) for emergency beer reserves.

The only down-side? It weights about 500 lbs and the top is too big to get up the stairs if I ever needed to. Feedback and suggestions for further improvements are appreciated.

If you need to move it, cut it in half, put in facing plates on both sides, move it upstairs, then bolt them together. Maybe put in alignment dowels through the facing plates to keep the top halves level. Should work.

Nice table. We’d all love to have a work surface this big.

Nice job! I did this to my saw when I was building a lot kitchen back in the 80s, man did it help with sawing sheet goods, 50” fence with 60” table left of the blade, and a 8’ by 10’ out feed table. now a days I have a small portable table saw and I mostly use my hand tools no call for custom kitchens as much these days.
Having that big work surface I am sure will make things safer and more productive in your shop. a,gain great job on your table saw.

Hey BigIke – thanks for the comments. I will email you the plans that I drew up. The torsion box was built on 8×2x4’s that I jointed and shimmed (with cedar shims and playing cards) until they were flat on my basement floor. I then put down two sheets of 3/4” MDF as a flat base to build the torsion box upside down. The box I constructed with offset 9.25” on center MDF cross braces. I chose to stagger/offset the braces so that I could staple them on both sides. I attached strings to the diagonals to check for (a) even diagonal dimension and (b) no twist to the box. 1/2” plywood was added for the backer and the cabinets were then constructed.

I’d like to build something like this…I’ve always wanted an aircraft carrier-like deck for my outfeed needs…
Would you share your plan with me?

Great build. It looks beautiful! Are you still happy with the way it turned out? I can’t imagine why you wouldn’t be? I also had the idea to build a torsion box table top around my contractor’s saw. Just setting up shop myself, finally I have a dedicated 24×24 space to call my own. I’ve been looking all over the internet for something like what I see in my minds’ eye and viola here it is. Would you mind sending me the plans?

Thanks in advance,
