Carry plywood by yourself is really a pain. Here’s
a helper that allows you to roll it around instead. Just
clamp this caddy to the board’s edge, tip the sheet down
onto the wheels and off you go.
The caddy will fit plywood that’s 1/2" to 3/4" thick.
Its sides aren’t glued together—they just slide on bolts.
I put 7" lawn mower wheels on my caddy so I can roll it
over an uneven driveway or my yard when I’m unloading
plywood from my truck. Large wheels are ideal for
a shop floor, too, because they roll easier than small
wheels. Of course, you can use wheels of almost any size.
To make the caddy, temporarily nail together its
three parts, flush at the bottom. Drill a 1/2" hole for the
axle through all three pieces, 1" up from the bottom and
centered between the ends. Drill two 5/16" holes for the
1/4" clamping bolts. Position the holes 2" from the bottom
and 2" from each end. Disassemble the parts.
To assemble the caddy, slip a washer onto the axle bolt
and slide the bolt through one wheel. Slip on a nylon
bushing, then slide the bolt through the axle hole. Slip
on the other nylon bushing, the other wheel, washer and
two nuts. Lock the nuts together, leaving about 1/4" on
either side of the spacer. On the 1/4" bolts, slip on a lock
washer and a fender washer, then slide them through
the 5/16" holes. Slip on the other fender washers and
thread on the jig knobs.
