Step 12: Now prepare the axle
Here I used a pair of Vice-Grips to hold the cone as I tightened the locknut against it as firmly as possible. This way I can consider the freehub-side locknut to be as good as the head of a bolt in terms of adjustment. Between locknuts on either side, I want this to be the one to give way last, and act as a semi-permanent part of the axle itself. Once locked, I'll know that wrenching between both locknuts wil always result in the "freehub-opposite" side loosening first.
