Ideas?
These may be too large, but gives you an idea.
The first bench base is from salvaged kitchen cabinets, with 3/4 inch birch plywood top, heavy coat of spar polyurethane. Six feet long by 24 inches wide. Cabinets are held together laterally with a couple of screws Top secured by screws in each corner. 30 minutes to knock down, have moved seven times. Preempted for current use but was loading stations. Very cheap, tons of storage. Top need refinishing?, simply drag out the sander and reapply polyurethane. No skill at all to build (obviously).
Second bench is 84 x 36. Top is a solid wooden door 1 ½". From salvage. Built originally to hold a T-bird 460 CID mill rebuild. Did the job and then some. Legs are 4x4, 44 inches high. Rails are 2x4. Top is fastened to the top rails, bottom shelf is 3/8 plywood, free floating, notched at ends to hold down lateral movement. Carriage bolts hold the rails to the legs, two bolts at each corner. 8 bolts on top and 8 bolts on bottom and it is dis-assembled. This too was moved 7 times. Could not live without it. You could get fancy and dado the legs and rails to fit smoothly, which I did not do, works just as well. Have refinished the spar polyurethane 8 or 9 times. Green paint is all I had handy.
Excuse the mess. Several different projects underway.
