large lazy susan
no not the MIL.
I need a large HEAVY duty lazy susan about 500 mm diameter and capable of holding 200 kilos...am I in dreamland.
Ive seen ones as shown on ebay the right size but weight unknown, a way around that would be run 2 or 3 of different diameters I guess,
its for a 200 litre drum grow bed that needs to be moveable so all sides can get direct sunlight

Why not just a meaty stud in the middle with a tapered roller to take the weight and a deep groove ball bearing to stop it from tipping over?
Alternatively, you application doesnt require super high levels of precision. why not a deep groove ball in the centre to locate the drum, then three or four casters around the preriphery to take the load? All you need to make is the casters and a lug / bearing seat for the middle.

Hi and Welcome to a Top Forum. Found this on Google from Carrolls Woodcraft Supplies, a sponsor on the Wood Work Forum. 450 diameter and a load rating of 300kg.

You probably want it tomorrow but you don't really need a lazy susan, just get some conveyor roller balls like these and screw them (in a circle to fit underneath the drum) to a piece of ply or metal.

The rim of the drum will prevent the drum skating off the balls.
Here's a lazy susan I made with them to support 3 bench grinders..

While these look good think I'll go with Bobs idea that way I can get those big bearings to fit inside the rim of the barrel. cheers Kyrn appreciate it.

This 9 storey atrium is inside The "Arab Oil Exporting Countries" Building in Kuwait.
The Atrium is on the 3rd floor and each tree is inside a concrete drum sitting on a steel plate on bearings.
Each drum, steel plate and tree weighs about 1 ton.
The trees are rotated by hand once a week along the same lines as he OP required.
The bearings must have been pretty special because I could rotate the trees with one hand!

Many years ago I made a kick wheel for pottery. I used a disc brake hub to seat the lower tapered roller and the same at the top under the platen. Located at the bottom was a 4' round lump of ply with sides, I dumped a heap of concrete in it for weight. To operate you sat on the inbuilt seat and turned the concrete wheel by using your feet. The weight of the concrete wheel kept the wheel spinning in between kicks. The kick wheel dates back to the days of the discovery of the wheel, of course vehicle hubs came along much later and were ideal for the application by virtue of the weights and forces placed on them in their native home - the car. Car hubs can take some serious weight a single hub should be suitable for your application.
You can get trailer hubs from Supercheap for around $30, even better a hub from the wrecker would be cheaper and comes with bearings. You would of course need to make some feet to extend the base out to the 500mm you mentioned. Easy peasy, the hubs have studs ideal for bolting to the base. Ebay has some hubs listed as 'lazy' hubs. They look to have a larger diameter so may be meant for this application???
