I am replacing the standing rigging on my boat. The pins holding the fore and aft stays are frozen in the hole on the mast head. any ideas on how to remove the pins without destroying the mast head unit.

Try a "little" heat like from a heat gun, reserve the blow torch if all else fails, after heating spray on some penetrating oil, like blaster and let it set overnight. Then with a series of quick taps with a drift work it back and forth. I got mine out this way without any issues.

Boy, That alone tells you that they are long overdo for replacement. Like said above Some PB Blaster soaked overnight and slowly tapping and working it will loosen them.Take your time. Funny that when I replaced my rigging those pins fell out on their own. If the pins are frozen ,How are the turnbuckles?

Mine were "frozen" and I later realized they were slightly damaged, not from corrosion. I cut one out with a dremmel tool.

I cut the inside of the pin on each side, removed the middle, and then punched the pin ends outward.

During a storm my mast and rigging got beat up in the slip up by another mast next to me.

I agree on the heat and PB Blaster.

I had Honda Prelude years ago and when I went to change the spark plugs they would not budge. When I tried to force one of them a little it made a sound that you instantly know is going to do serious damage if you keep going.

Tried various penetrating oils over a couple of days. No go. Then it dawned on my to try heating the aluminum block knowing the aluminum would expand faster than the steel plug.

Started the car and let it run about 30 seconds. Put the ratchet on the plug and it came right out with normal pressure as did the other three plugs.

I made sure I used anti-seize compound on the new set of plugs.

PB, let it soak in overnight. a little heat applied to the masthead (not the pin), a 5mm punch and a couple taps from a hammer. It'll come right out.

That's getting the pieces apart, but that's only step one. Now you have to be sure the fittings are still good and that the replacements are protected from future corrosion. I'd check the tangs and fittings for strength, freedom from corrosion and dimensional integrity. Otherwise I'd always be wondering...

I just removed mine. Lots of corrosion and the mast head was cracked in a few places. But, lots of penetrating oil, heat and time. Patience and persistence will pay off.
