Rotating Model Stand / Sculpture Pedestals

I just finished a couple of quick CNC projects. One was a rotating stand for a figure model to stand, sit, or lie on. The other was a few sculpture pedestals to donate to my son's school.

Rotating Model Stand

This stand was built for use in our sculpture studio (West Huron Sculptors) to let us rotate the model rather than have the sculptors move around the model. Here's the design which is meant to break down for easy storage when not in use:

The rectangular top is removable and is used for more stretched out poses. 

An exploded view: Eight milk crates, a single 17" lazy susan bearing, six 1" ball bearing rollers, two 4' diameter baltic birch plywood circles, three Poplar 2x4s, and a plywood top. 

This was very simple 3-axis CNC routing.

Installing the Lazy-Susan bearing and the six 1" ball bearing rollers. That'll support about 500 pounds - and so far all our models have weighed less than that...

These were purchased at Lee Valley and Woodcraft: Lazy-Susan Bearing, Ball-Bearing Rollers

Routing the notches for the rails to overlap the rotating base plate. The router was balanced between the rail and two pieces of MDF along side it.

The corners were sawn out and cleaned up with a chisel and chisel plane.

Here's the stand in our studio with a double stack of crates. The bottom circle has guides to prevent the crates from slipping. First without the top (good for a standing pose):

Sculpture Pedestals

This project was a few simple 10" x 10" x 5" and 10" x 10" x 45" sculpture display pedestals. These were made to be donated to my son's school for use in the art department. These were CNC cut with a 3/8" down-shear and a 3/8" compression bit.

The taller stands had a few small joints at the top and bottom then a long one in between:

The interesting thing about them is the joint design and the resulting corner condition which gives them a bit of detail rather than being completely straight-forward boxes. You can see how the joints go together here and the corner detail at the top left:

These were painted satin black by my son and his friends and donated to Washtenaw International High School.
