The 33-2 has a unique system, with a stainless steel part ondeck, trough bolted with bronze bolts to an aluminum block / backing plate inside that connects to an adjustable rod. The problem i have is the galvanic corrosion that occured between the bronze blots and the alumimun backing plate. The thickness is maybe around 1/2 inch and everyting is stuck together. i was able to undo the nuts and i see the white corrosion that fused the bolts to the aluminum block. So far I sprayed white vinegar with water, i used some heat from a heat gun, and a hammer with a block of hard wood. nothing happened... Any other ideas on how to break this loose ? what are my options if i dont want to detroy the parts or the deck! At this point i kind of wish i never started but at this point i'm afraid to get a leak that could damage the balsa. i know i'm looking for a miracle, but i have faith in you! Thank you.
