ZFT3 Tower Knob stuck to the bolt - never seen this ..

Hi everyone,

This is the breakaway knob which you loosen at the top of the tower and it releases the 2 half brackets that join the front legs to the back part of the tower.

You loosen these any time you want to collapse the tower (mini or full size)

Well this one all of sudden got tough and I cannot remove it, even removed from the tower took to the work bench and man it won't budge any further, oil .... yikes!

any ideas?

I would normally soak it in WD40, but if you've already tried oil maybe try using a soldering iron to heat up the bolt. That's a way to open the bolt if Loctite (threadlock) had been applied, so maybe it will help even if there's no Loctite.

I would get a torch out and heat it up, on my 12 they were all loctite. So you may need to hear it up to loosen it.

I think so .... need to remove but it,feels,to me like the threads inside the tower knob are messed up and let it travel enough to remove it.

Threads have galled up and seized together. This is a common problem with aluminum and stainless steel threads. Time for new parts, as the aluminum knob is stripped for sure and threads on stainless steel shaft are probably rolled over. You may be able to save the shaft by running a die over it once you remove the knob. Getting them apart is the hard part. In the future to prevent this I would recommend moly on all stainless or aluminum threads.
