Electrifying a Radius Dish Sander

[Paul Montgomery]

This is a luthier tool and I know it’s not for everyone, but I’m thinking that there might be some clever people here who just might find their own use for it.

I am doubtful that you could power a guitar sized radius dish with an electric drill. Also, that plastic friction disc would not be sufficient for a large spinning dish. I power my radius sander with a 1/3 hp electric motor and the dish runs on a large lazy susan bearing.

Here's mine. Like Barry I use a 16" lazy susan bearing. Direct drive like you see used on a carnival ride. The motor is separate, mounted on a hinge and leans against the bottom plate with an 'O' ring on the drive collar that grabs the perimeter. The double thickness dished plate is interchangeable and locks in with center and edge dowels. It stows away nicely which is important in my small workspace.

When my dryer caught fire and needed to be replaced I stole the 1/3 horsepower motor from it to make a motorized dish. I too use lazy susan bearings. I'm not sure if a drill motor would turn a large dish at a fast enough speed. the dryer motor seems be be just enough power, I wouldn't want any less.
