I need to make a rotating platform for a person to be able to stand on that i can rotate by specific degrees that i cut into the top (like a wheel of fortune wheel). I need some type of bigger ball bearing lazy susan type setup. Does anyone have a source or advice on something like this? thanks

Jack..
We used to use an inexpensive 15" dia ball bearing for a lazy suzan or a TV swivel.. try cabinet hardware shops.

Jack,

Why couldn't you use the following roller bearings mounted on a board in about eight palces. Have a second top board with a central pivol point to be able to rotate the top board? Place as many rollers required to hold the weight. They do not need to be aligned as these roll any direction.

Just a thought?

Jack, having always gone for overkill, when I needed to construct a platform 6 feet in diameter, capable of rotating, and supporting the weight of 1-4 women, I had a frame work built using a spindle and hub assembly for a trailer wheel, these assemblies are designed to operate at highway speed with loads upto 3500 per assembly, so for a slow turning platform, it was overkill, but effective, and affordable.

I went down to the Woodcraft store and got 6 of these for $3.50/each. They have 1" balls in them.

sorry Bruce, this is a family oriented forum, those pictures might corrupt the members, and take away from the time they should be spending with their bots.

Jack,
I would be a bit worried about the six of those bearings taking all the weight and not denting and running a groove in your material. I would suggest either lots more than six of them or a metal track for them to run on. If you figure 250 pounds on the points of 6 ball tops (theoretically 0 square inches) that is a lot of psi.

What if you laminated a piece of formica on the underside that contacts the roller bearings , This would help from creating a groove and distribute the weight more evenly, i would use more than 6 also . its always better to do it right the first time instead of having something you dont like to use. You always put quality in the work you do for others why wont you do the same for yourself?
