Not really pertinent, other than that it's mast step related, but it may cheer you up by showing what you COULD have to deal with. Before & after pictures of the mast step in my boat.

I think Boof has it. Use the PB blaster once a day for a week and rap around the outside the the mast with a wooden block and a hammer. This helps to draw the PB Blaster into the microscopic cracks caused by the blow. The use a slide hammer, attached through the mounting holes so the impact is pulling out, not driving it in.

Aren't boats fun?

I don't know where you are. Here in Maine, it's cold out.

Get the whole end of the mast/base cold, then quickly heat all around only the mast with a propane torch, waving it a bit. As the mast expands it will pull away from the base. Alternate heat and cold, always heating just the mast. You are trying to keep the base cold, while heating the mast to increase it's diameter. As soon as the heat flows into the base, stop and let it cool.

Rapping around the circumference of the mast where it's bound to the base also stretches the metal, and as mentioned helps to open tiny voids for capillary attraction of the PB blaster or other penetrants, like automatic tranny fluid mixed with acetone.

Thanks for all the advice!

I have been spraying the seams with PB blaster daily and giving it a couple knocks with a hammer and block of wood. No movement yet.

I need to get a torch to heat the base and see how it goes, hopefully this weekend.

I had the same experience with my Catalina 27. I had to cut the step out of the bottom of the mast, (I used a sawsall to cut from the inside of the mast just through the step, in wo opposing locations, and then it almost fell out), and then bought a new one from Catalina Direct.

My step was too corroded to be usable, even if I had gotten it out of the mast in one piece.

God looks after fools and drunks, and I know I'm not a drunk...

But yeah, after exhausting other options trying to save the mast step, I very carefully cut the step from the inside, just up to inside of the mast, at maybe the 4 and 8 o'clock positions, and the step almost fell out.

Really great that replacement steps for Catalina 27s are to easy to come by-

Hmmm,,,I didn't think that image would attach-that's the hinged mast step from Ballinger Spars, which eased stepping the mast quite a bit-but that's a little off topic...(at Ballinger they recommended adding another bolt at the front of the step for the mast attachment).
