Kaleidoscope with Removable/Interchangeable Object Chamber.
Note: These are my shop notes from 1993. I have tried to improve the notes a little and added the pictures. Measurements are based on mirrors of 7 3/4 x 3/4 inches. Plexiglas of 1/16 inch thickness was used for the dust caps and the cells. Adjust and verify your measurements.
This kaleidoscope was turned from koa and the overall length is 9 3/8 inches.
I have made multiple cells to fit one barrel and have made sets which included two barrels (one with three mirrors and one with two mirrors) with interchangeable cells. In addition, you can cut colored Plexiglas filters to fit between the cell and barrel. There are many options and possibilities.
