This is a 2013 picture. Only one I have.
The bottom is on casters, made from 3/4" plywood and 1x4's, glued and screwed, stained and coated with polyurethane. 24"w x 48"w x 30"h.
The top is 1x6's with 1/4" backboard.
It is extraordinarily strong, holds much reloading tools and components and mobile if need be to fit through interior doors.
Note the trimmer, powder dispenser and a few other tools are mounted to a wood base and are fastened with carriage bolts and wing nuts to the counter top base and easily removed.
