Hey,
I just bought a new tendon for my europin base. But when i tried removing the tendon to replace it i relised that the screw was threaded 
Tried a few methods off the net to remove it but it is stuck pretty good. Any suggestions ?
And if i just cut it, where do i get a new one ?
Thanks
An eazy-out is only for when you snap it, it will not help if the nut is seized and you may just snap the ezy-out if it is well stuck. If you have not snapped it, and have a proper sized driver:
try
(1) Penetrene or WD40 on the nut, let it soak in peroperly for a while
(2) heat the whole bolt / nut with a soldering iron. If it has a thread locker applied it will melt it
(3) put the whole thing in a vice. Place your screwdriver / allen drive in the bolt and press down really hard and try to undo it whilst another person hits the driver with a hammer. The shock loading will loosen thinghs you never thought you'd get undone.
Emphasis is on proper sized driver cos once it is rounded then you are in more trouble. Do all the above before you bugger the fixing
If the head of the fixing is stuffed, cut a slot in it with a Dremel or similar so you can use a flat blade screwdriver in it with steps 1 to 3.
I have had better luck with a left handed drill bit as opposed to an easy out for stuck bolts, easy outs like to snap off then there is hardened steel stuck.
Did you try vise grips?
i have replaced a tendon in the past where the screw could not be un-screwed but instead you had to screw it all the way through untill it came out the other side.
Initially i thought that the screw was threaded, but it turns out that it is a design feature.
This im my problem. The tendon broke in half so i was able to remove half of it and replace it with the new one but the other half i couldnt get out. so i just dug out the rubber to see if i could grab the bolt/screw/whatever with some pliers. And now this is where im stuck at :)
pic two is of the threaded allen key thing. you cant really see in the pic but it is countersunk. so its hard to get anything in there.
I have a couple of those in the shed. Once they've been on the water for a few years they can be difficult if not impossible to remove.
Buy yourself a new base and use the new tendon to as a replacement in the 12-16 months time. Hopefully the new one won't be so stuck in that time frame.
Thanks for the help though everyone 
Thanks for the help though everyone
Thanks felix good tip!!!
Did a temporary fix on my base for now untill my new one arives... just drilled it out then put an ordinary nut and bolt in 
Im not happy with it but atleast ill be prepared for this weekend 
Hi I see probably you've tried long nose pliers (better still long nose vice grips) and they are not gripping If you have a warding file and file two opposing flats on the pin and with the use of penetrene as mark mentioned work the pin back and forth the pin should eventually come out.
So Aussie - it has no nut on the other end, just threaded into the side of the cup?
If so that is a sh!thouse system and bound to fail.
I had one more for you, but you've resolved it
Well i replaced the one that was threaded with a bolt and a locking nut. And i was able the reuse the other original one. What ive done hasnt really changed anything but the appearance. But we will c this weekend
A poster said: “When you get the new one, dismantle it and apply a bit of never seaze graphite marine grade grease and it will be easy to undo ever after!”
A point of caution:
Nyloc nuts are designed to be an interference fit on the thread of the bolt/capscrew. They grip the thread by FRICTION. If you apply an anti-seize compound, the frictional force will be seriously reduced (and probably will not be more than a normal nut) and it is likely to unscrew in service.
Hope this helps.
That's a threaded sleeve with an allen bolt run thru it, if you were to grip the sleeve with needle nose vise grips and drill into the allen head with a left handed drill bit. turning to the left of course, the bit will catch and grab and unscrew the bolt then the insert can be re-used.
But it's all been drilled out now so never mind.
Left handed drill bits folks.
Drop it to your windsurf shop , they LOVE fixing them ( Not )
Being one of the most important parts ,your best spending the dollars and replacing it with a new BASE.
One other thing................ Often there are other sloppy components
Get NEW ONE
Where you sailing when it let go ? ...........rope saver was a great invention to the uni
