In ShopNotes #50, it shows a leveraged caster system meant for mobile cabinets. Casters are mounted to a pivoting wood crosspiece, which is controlled with a sliding lever that comes through the side of the cabinet. Pull it, press down, and slide over, and it moves wheels into contact with ground, clearing corner posts.
I am thinking of using the same thing on a Shaker style work bench, but am concerned about the weight. top is 1 3/4 thick scrap oak reinforced with cleats, so fairly light compared to the massive tops on others. Cabinet will be 3/4 oak plywood, with drawers. I assume total weight to be around 400 lbs.
Q: How can I figure out if the approach shown in ShopNotes will support my bench? I have not engineering skills, no tables, etc. Hard to explain without looking at the mag (ShopNotes #50, pg. 22). Anyone out there that can figure this out? Thanks!
