It was tight enough to where I couldn't twist it by hand, it only began to twist when I started tightening the nut on top.
Buddy,I know you don't want to hear this,but that's not tight enough. It's a super easy fix right now. Take it to any machine shop and ask them to knurl that part of the stem. It'll take them about 5 minutes.
Hell,where are you at? I'll knurl it for you. I promise I'm not trying to be a jerk here,but you really cannot take any
If you opt for the loctite route,which may be fine too, don't use off the shelf loctite from your local auto parts store designed for holding nuts on to bolts. That won't do. There is a particular formula of loctite designed to hold bearings in place that was mentioned earlier here. That,and only that,is the loctite that you NEED for this job.
Fix while you still can. Be safe. And good luck on the build :thumbsup:
