Diameter of the circle formed by the casters is about 35 in., diameter of the round tray base is 19 in., round tray base is about 9 in. high, center hole is threaded for a standard 2-in. black or galvanized pipe (see last pic), casters have 3in. cast iron wheels. Tray, legs, and casters are all cast iron(everything except for the obvious hardware). It weighs about 40 lb.
Rol-Ezy Chief casters are neat - instead of a ball bearing race at the top to allow them to swivel they use a single conical post that rests in a cone on the main casting. They swivel and roll very smoothly. A set of 4 of these sold recently for several hundred dollars.
All original, except the caster axles (grade 5 bolts w/ lathe-rounded heads and threads cut to just the right position), and the washers and nuts that hold the legs on.
Green pipe in last photo is for perspective, it's not included in the auction (maybe by special request). (Yard stick and V8 can not included either.)
Shipping by cheapest method (probably FedEx). Legs will be removed from the trayfor shipping.
