Hi all

I have a chinook uni (pictured below, sorry about the poor quality). I need to know If I can unscrew the silver pin from the tenon joint. I've seen other joints and they seem to have a threaded insert. I'm guessing I need to put it in a vice to get it undone but I don't want to destroy the fitting to see if it works. Has anyone removed these successfully? Thanks

It's probably been put in with "locktite".
If it doesn't want to come undone, heating the bolt up will weaken the locktite, use a soldering iron, heat gun or hair dryer, don't get too much heat on the rubber of course.

Probably don't want to hear this but when the bulge joint broke on mine I had a mechanical engineer friend do just that, heat and unscrew. Then went and purchased the replacement parts and the new pin just snapped at the end of my first sail.

In hind sight felt like a lot of messing around when I was able to replace it all for $60 from Surf Sail Australia website.

But if you still want to save a buck, the heating thing and clamps seems to work.

Thanks for that everyone, I'll charge ahead. I'm actually using the pin for a different project that requires the removal of the uni joint and replacing with a chinook mechanical one but you can't seem to get them with the pin. Thanks again
