Duty Caster
How to build a mobile wall partition?
I need to build a wall on wheels for an art gallery, they need to be about 8 feet high, and it needs to be build for cheap.
My idea is to install 4 heavy duty casters on double layered 3/4 plywood at 1′ wide and 4′ long. Then on top of that build a skeleton frame out of 1x4s and attach 1/4 ply to the frame.
Does anyone have a better/ cheaper idea on how to do this?
Instead of using double 3/4″ plywood for the base, use a 4′ long 2×4 attached to a 1′ 2×4 tee at each end. Then attach your casters to the ends of the tees, your vertical wall section and you’re done.
The advantage besides lower cost (approx. $2 for a 2×4 x 8′ long) is lighter weight. The base will weigh much less than 1 1/2″ of 1′ x 4′ plywood.
