Elevating Gladiator workbench?

[130fe]

I have one of the older 8 ft non adjustable height Work benches. I want to add some height to it so I can fit a HF 44” lower box under it. It is currently 37” high (on bottom of bench top) and I need 40” of Clearance. Wondering what I could use to sit the workbench on (like 4x4s) to elevate it and keep it stable. Any info would be appreciated.

PVC pipe just slightly larger diameter than the leg and 6" long (each leg). Apply an end cap and fill the pipe to the desired height with sand and top with plywood circle ( so the table leg has a solid base inside of the pipe). Put each leg into one of the 4 pieces of pipe. Level the adjustable leg as required. This makes a somewhat easy stable fix with no worries of the leg falling off a 4x4 etc.

That would be quick & easy. I think I would try the same thing in galvanized pipe, if you were going to be wailing-on the vise with a baby sledge.

Wood is always good. Could also be metal, slice of a 3 x 3 x 1/4" box tube or a solid round.

If there's a center hole in the bottom of the leg you could cut the hex off a cap screw to make a pin. Now drill the spacer material for a clearance hole and the pin will keep the leg from sliding off under most conditions. If there's something like a 4 bolt pattern you could drive a deck screw (etc) thru that as an insurance policy.
