Re: New X-brace Group Buy!
I had a similar problem where one turnbuckle was able to be completely threaded while the other gave me a lot of resistance once I had It threaded most of the way by hand and then used a wrench, I think this is where I messed up the threads.My problem is a bit different than what you described. I didn't take the turnbuckle apart from the upper arm. What happens is on one set, I can screw the turnbuckle all the way up the upper arm so that there is no space left on either side of the nut. On the other set, I screw it up trying to get all the way up to the upper arm and when there was a few mm left I met some resistance so I couldn't tighten it anymore with my arms. Then I tried to use a wrench and I guess I applied so much force that now I can't unscrew it any more. One set, I could use my hand and get it all the way screwed in, the other I couldn't and by using a wrench I think it striped or jumped a thread or something. Regardless, I can't unscrew one of the turnbuckle/upper arm set no matter what I do.
I'm worried that if I go to a shop and they are able to unscrew it, the threads inside might now be unusable.
