having mobile bases in a multi purpose garage is a must. i went looking at other mobile bases, either commercially available or home made on YouTube. i was dissatisfied with everything i saw: 3/4” EMT electrical conduit squishing retractable wheels down, lockable castor’s that still slightly moved, castor’s at the 4 corners that can be easily tripped over, using alot of torque and pressure to lift the stand itself.
well, here is my idea. this came from bumping into a website that used compound levers and fulcrums to press bio material into briquettes for fire fuel.
if i understand the math right… this compound lever can EASILY press down nearly 4,000 square foot pounds. now, i wouldnt need 4,000 sq ft lbs to lift a planer and a stand, or bandsaw stand. so, i should be able to press down with MINIMAL force to lift a heavy load, more than what i have seen other mobile device/retractable feet & castors do. this was a mandatory thing for me in a mobile base.
this is a work in progress, as you can tell by my 15minute put together mockup 2×4 home depot scraps and 6” lag bolts i had laying around of just 1 side of a mobile base (yes, you will need 2). I put my planer on the platform plus my entire body weight, and i pressed down with little force and kapow, worked like a charm.
next (when i get heat in my garage), i will see how using smaller profile 1×4 and 5” stem castors will function stress test of horizontal and vertical platform movement while lowered and while raised. hmm… maybe even using bearing instead of lag bolts might even help a little too.
