I did mine with a Bora Centipede table base with MDF tacked on top of flat planed 2x4 (1.5 x 3 now) frames and it’s working great. I would have done the floor thing, but my back already hates me so I spent the money to lift it 30" off the ground. Honestly, I think the spoil board arrangement is taking up more of my brain power at this point than the table build ever did.
I like the IDEA of a torsion table, but by no means do I think it’s NEEDED. When I get a bigger shop and the LR3 can have it’s own permanent spot, I’ll probably look into a torsion table build and repurpose my Bora toys.
