Mirrors:  Three for each kaleidoscope

Description:
Acrylic mirror:  7-7/8" x 1-1/8' x 1/8' finished size

Material Supplier:
US Plastics Corporation.  Item number 42461  Clear Mirror Sheet 24: x 48" x 1/8  $39.12  (February 2007)

Yield:
Each sheet will make 110 mirrors or enough for 35 kaleidoscopes

Preparation:
First:  On a table saw with a carbide-tip blade, cut the mirror into strips measuring 7 7/8 inches, then rip into individual mirrors.  This should only be done by someone with experience in operating table saws with a carbide-tip blade.  Note:  The 7-7/8-inch dimension was chosen to allow for the blade kerf when cutting 48 inches into strips.  This length should be approximately equal to the length of the PCV tube of the kaleidoscope.
Second:  Use this cutting pattern-- six mirrors wide and 19 mirrors high.  For a larger view, click on the thumbnail to the right.
Third:  Vacuum the sawdust from the mirrors.
