Torsion Box plans

Anyone know if someone sells a torsion box for the 1000mm, with my working hours i don’t have time to make one, or good plans for one

Thank you

They are quite huge, heavy (if out of mdf like mine is, anyway) and I imagine difficult to ship.

People have used hollow core doors (which are tortion boxes). I wonder if you cut and stacked two such doors if that would create something very stable.

I didn’t think of this I might try it thank you
