The PVC beach wheel experiment seems to be working out well.

Drilled a 1" hole in the PVC end cap, added two bolts 1 3/4" to the axle, in opposite planes to center the axle, glued the end cap onto the pipe.


the axle and the bolts are all contained inside the tube end cap glues it all together nicely. the best part is that if I dont like it, I only spent 10 bucks on the pvc.
