Hello all,
I’m looking for some design review on mounting my workbench top to its base.
I’ve been working on building my workbench. The top is 3”-1/4 x 33”x79” Roubo-style lamination of SYP, while the base is a hydraulic scissor-lift table. The lift table has a 1/2” thick, 30”x30” steel plate welded on, with thinner sheet metal welded to an angle frame about 50” long.
In fastening the top to the base, I want to maintain air flow across the bottom, as well as allow for expansion and contraction.
My understanding is that the best practice for screwing a top like this down is that I should screw tightly into the center of the expansion direction, fit into a slip-fit hole, then snugly screw along the direction of expansion with screws fitted into slots.
Since I don’t have a headache-free way of slotting the 1/2” steel plate, and I want to keep some airflow, I’ve decided to screw some mounting pads into the top, then attaching those to the steel plate with threaded inserts so everything is removable.
It seems that this solution will feed two birds with one scone, but I’d love some feedback if I’m missing something. Concepts in photos.
