Default Cotter pins

Thanks for all the hints.
Unfortunately I am all out of nuclear devices and plastic explosives.
At the chain plates I was suprised to find that when I went to pull the cotters, one of them crumbled to bits in my pliers. I wasn't even able to get it out with a punch, as it was welded to the inside of the clevis. Wow, am I glad I decided to rerig. At deck level my dremel with a cutting wheel did fine work cutting the ends of the pin on the one that was frozen, and then just replaced the pin. They looked to be bronze cotters.. Anyways, I will look for the tools mentioned. I have already purchased a pair of rigger pliers from Brion's shop and they have given a good grips on the heads.

One more thing I would like to ask, this regarding the spreader tips. When removing the spreader boot I noticed on the aluminum spreader tip fitting that there is a hole going horizontally through it with a cotter pin that doesn't allow the shroud to pop out. Is this hole generally used for a serving to tie the spreader to the proper angle, or should I reinstall the cotter for this and possibly drill a couple more holes through the spreader tip to apply a serving.
The wooden spreader is very narrow at the tip, only three quarter of an inch and I do not want to drill holes if it may weaken the end of the spreader.





Fair winds, and a very merry holiday to all.
Bob

No comment on the spreader itself. I don't think you've mentioned what size Columbia anyway.

The cotter pin to retain a slack shroud could remain, and I would leave it in place or even 'upgrade' it to a bolt or clevis pin. We normally use some sort of metal fastener, be it a captive design spreader tip, a retaining pin, or monel wire, to secure the shroud INTO the spreader tip. Then we use tarred nylon twine to secure the spreader from moving up or down via a lashing from the cable above to the cable below the spreader tip, back and forth enough to suit the loads. The lowest load should be considered as a man standing on the spreader, it will happen when someone climbs aloft.

Enjoy.

Brian,
It is a 1962 Columbia 29, hull #39.
The spreader tip has a aluminum fitting that goes around the sides of the wooden spreader tip. It goes around the end and down the sides of the tip for 2 inches, and is secured by two 1/4 inch aluminum rivets that go completely through the spreader and fitting, and at the very end has a notch 1/2 inch deep to hold the shrould.

It wouldn't be difficult to install a small diameter ss machine screw in place of a cotter pin as the retainer on the end.
And I will lash it down after acheiving the proper angle. It wasn't lashed before and just held in place by tension of the shroud.

I was looking at the knipex catalog on line and didn't see anything refering to "Magic Pliers" Were you refering to the small channel lock type pliers they have?
