I've got a pretty old Mavic 819 wheel and the nipples keep loosening from the spokes (almost to the point of tightening several after every ride). How do I keep them secure...loctite blue? I don't really want to take any completely out, b/c the nuts that screw into the rim seem to be plenty secure.
Thx.

Thx...can you elaborate? E.g., is it likely that they are generally undertensioned? Or, some under, some over? The wheel is actually pretty true.

Yes, generally under tentioned could be a cause - as could spoke-windup
Spokes wont loosen with properly tensioned wheels - make sure they (spokes) are stress relieved and not wound up.

Any thread locker is a crutch for a poor wheelbuilder - in fact many great wheelbuilders will use a lube of their choice on the threads.

To expand on what highdelll said - chances are all the spokes are too loose, and that the ones you tighten are getting twisted instead of actually tightening on the threads. If the wheel is "actually pretty true" even with a couple spokes being obviously loose, then they are nowhere near tight enough. It should be going out of true (from tension imbalance) long before the spokes are obviously loose.
You want the OPPOSITE of thread lock; the wheel is old, so those nips have some corrosion in the threads, which is making it hard to properly tension the wheel. Use some penetrating lube on all the threads, tighten them all a quarter turn, then tighten the drive side another 1/4 turn, stress relieve them all, and then true the wheel by tightening only (max another 1/2 turn).

Read the stuff linked from my sig. All will be revealed.
I scrolled through it briefly, but I missed the "meaning of life" and "what happened to Unicorns?"
:skep:
