Is anyone else having problems with their TT2 coming loose? I have really cranked down with a button wrench (requiring me to remove the weight to do so)...and again, I found my TT2 starting to loosen up last night. Standard 3/4" wood CP... not sure whats up. I may try a different "nut" this time.
Is this from use with the steering wheel or just the standard knob?
The hole in your panel may be a little too sloppy and allow the spinner body to shift laterally and cause the nut to loosen. If this is the case, you can wrap a few layers of electrical tape around the body of the spinner so it better fits the hole in your panel. If it can't shift, there's no way for it to loosen.
Also make sure you don't twist the nut down too tight. It's possible that it was torqued so tightly that the nut expanded to the point where it almost popped to the next thread, and finally did so over time. If you think this might be the problem, and you'll know if it does it again, you might want to use a new nut and just snug it the next time.
I can't say what could have caused it without being there, but these are a couple of things for you to consider.
