Motor Surrogate - 8" PVC Pipe

The Hyper9 weighs about 120 pounds and it is a challenge when moving it around the shop.  The Hyper9 extruded Aluminum housing was measured to have an actual diameter of  22.0 cm (8.66 inches) and a body length (from edge of fins to edge of fins with the end caps removed) of 27.0 cm or 10.63 inches.

Standard 8" PVC pipe has an OD of about 8.625".  Bushnell (847-297-4510 at 2110 Oxford Road, Des Plains, Illinois  60018) stocks 5 foot lengths of  8" PVC at $19.52 per foot and we were able to cut several 12" lengths for our own use.  The weight of the surrogate and the pair of cradles is 12.44 pounds (5.65 kg).
