CPT wood cell is made of 3/8" Finn Birch plywood. It is a very stiff multi-ply wood that will not flex under the weight of 8" - 13.1" primary mirrors.

For standard (non-conical) style mirror, it is recommended to dispense with the flotation pads (shown with the aluminum cell) and support the mirror directly on the cell itself. Wood is very stable thermally, so placing the primary directly on the cell presents no problems. Additionally, this method provides "six point" support (along the "spokes") for the entire mirror, past where flotation pads would be located on a 12.5" mirror. This is the best type of support system you can use.

The photos above are of a cell painted flat black. Cells are available unfinished, finished with a clear stain poly seal, or painted flat black.
