I recently did a show called "The
Effect of Gamma Rays on Man in the Moon Marigolds" for our high school
theatre. We set the
play inside a greenhouse that was both home and garden combined. In it I created four curved "seats" that from a top view were the parts of a radiation symbol. I actually built a
router jig to cut out both the circle and curved lids. Using a 5/16" or 3/8"
bolt I centered the pivot on a long plywood board. You could use
MDF I suppose. There are many who like using
MDF for jigs. Anyway, I made a simple box that kept the
router from moving and cut a large enough hole for the
bit and such to poke through. Then the
bolt was a pivot at the 1' or 2'
line as needed. I just turned on the
router and cut my circle. From there I just routed another panel like it's
template. Perfect circle. 2x4s on the inside and some 1/8" Maso to handle the curved outside and it was pretty curved furniture.
