Far easier to cut it off at the mate point, re-thread and replace the crown and brake. Impact to POI will be negligible and this work will take less time and be less stressful.Harrysigafoo said:Tough to understand why a good 'smith couldn't get it off???
did he say why?
If you turned it on, then you should be able to turn it off. The thread on choke tubes and braakes do get stuck but never saw one tha didn't come off with a steel rod into the brake holes and a hard hit with a 2 foot hunk of 2x4.
You must oil the threads and certainly anti-sieze grease (sometimes called brake grease) will work..if you get it off.
some delicate work with a dremel cutter bit down almost to the threads and then use a nut-cracker to break the threaded nut/furrele part of the brake will work to relieve the threads. Chase out the threads and get a new brake.
