We've done the same with our axles, hardened steel precision shoulder bolts FTW.

Our goal was to see if it would flip over, but since we had already decided to not turn on the side of the hill, it wasnt an issue. The center of gravity is nice and low so tipping over endwise shouldnt be an issue.

We have been using nylock nuts on all our major structural fasteners, easier than trying to remember what got loctite and what didnt, and they have not shaken loose so far.

We've used nylocks everywhere as well, nothing's come loose.

We've had some trouble with piston mounts, and some of our drive keys coming loose, but we've managed to fix everything so far. *fingers crossed*
