I'm having a heck of time posting from the phone....one more time

Well used spat mold....I need to build another. Shows the axle bolt areas

Outside view of mold showing the alignment tubes

Struts and spats epoxied together. The spat has carbon cloth inside. Very strong and secure. Flat head 8-32 "axle screw" countersunk into strut

And extends to the far side of the spat, securing the outside

Self explanatory?


Tang length out of the mold is 7.5". It is tailored to fit any fuse width from about 8.5" to as narrow as about 4". Tangs are thinner than the rest of the strut for flex and shock absorption.

Tangs designed to fit into one another. They are fitted into sockets (not shown), which are fitted into the fuse sides. There is no orientation with this style, but could be made differently if orientation or rearward slant is wanted.

The complete gear set (strut and spat) typically weighs around 105 grams. Wheels and axles weigh whatever they weigh.
