Layup consists of:
2x layers of blue cotton
2x layers of 6oz glass
4x layers of 9oz chopstrand glass
The reason for for the chopstrand mat is to provide the strength in flex to absorb bounds without reflex as rebound would break traction
Here are some shots of the stub-axle mounts. The big washer is just a spacer that sits on the machined bearing journal to allow me to snug everything appropriately.
I plan to do one for the race buggy on the vacuum table next. I'll cast some sidewalls to protect the wood from moisture too. The flex worked out well and I just have minimal sag with my weight in the buggy. Jumping on the back axle with the wheels on proved that it was both strong and did not bottom out on the ground which is a good sign.
