Center Foot - Caster Assembly How-To


For the Center Foot, I chose an Albion brand Model 21 Medium Duty Caster (21NG03201S). This caster has a 3" wheel, 4-1/16 x 3-1/8" mounting plate, 1" offset and a height of 4-1/16". Supports a 1200 lb. load and cost $26.

First, I drilled 4 x 5/16" holes in the JAG Caster Bracket plate. Using a medium strength Loctite, I attached  the 4 hex standoffs to the mounting bracket using split-lock washers (star-washers would probably be preferable here) and socket head cap screws. You don't want the hex standoffs to spin if you ever need to remove the bracket plate. Next I installed the caster mounting screws and star washers through the Bracket plate. *Note: These screws mount through the top (or inside) of the plate. I then attached the Half-Moon details through the Caster Bracket using machine screws, flat and split-lock washers. The caster plate is then mounted to the hex standoffs and finally the caster to the plate. *Also Note: The caster must be installed with the foot in it's upright position. Unless the caster mounting bolts are secured, they will simply fall into your foot assembly and you'll need to remove the caster bracket plate and re-assemble. The final result gives the center foot a ground clearance of 7/8".
