Recently finished a table build for the Journeyman Elite. Top dimensions 65x48. Wouldn’t want it any smaller in either dimension. 3/4" Baltic birch torsion box top. For the frame I used 5 layers of 3/4" Baltic birch ply laminated and machined square. Bottom shelf is a single sheet of 3/4" ply. Drawings and photos below.
The drawing shows the legs at 4", they’re more accurately right around 3.6" after machining. This doesn’t impair the build given that they only fasten to other pieces with the same dimensions. The drawer width ultimately changed to fit the torsion box as well. 4" blocks at the bottom of the legs represent the leveling feet/wheels I chose.
I used rockwool insulation to help reduce resonance. Ultimately a total of 4 pieces were removed to allow for drawers. A bottom skin was then fitted (not shown in drawing).
Laminations after initial clean-up planer pass
After sanding and edge routing
Bolted together with 8 inch GRK fasteners
Assembled, sprayed with a few coats of lacquer, drawers nearly finished
Machine mounted. Really happy with the outcome. The bench weighs somewhere around 300lbs and heavy as hell. Incredibly solid without a hint of wobble. Top is dead flat to as close as I can measure. The insulation seems to kill any hint of resonance. Cable management is the next hurdle!
