Help! Frozen Pin Removal.
Since Prout Catamarans is unwilling to remove the plain steel stay pins they "accidentally" installed in our Aluminum masthead and replace them with the proper stainless pins, I am wondering what people here have used successfully to "persuade" rusty steel pins to exit Aluminum.
In particular, I am looking for solutions that will not damage the masthead. So far, I am considering creeping oil (lubrication), hammer or hydraulic press (persuasion), Sawzall (cut the pins down prior to extraction attempts), and a wire brush (to hopefully reduce the OD of the exposed pin surface to a point where it is smaller than the ID of the hole in the Al).
I consider heating the parts to be a last resort since the masthead is a welded assembly and may lose strength or warp itself to death. Any other ideas?
Oh, and how many people have enjoyed the sight of plain steel pins holding their fore and backstays to the masthead? More info at www.vonwentzel.net
