Well, this has been discussed many times before, but what is YOUR favorite recipe for removing seized stainless fasteners in an Aluminum sub-structure?
Point of context for my current struggles: I am in process of removing my rudder (saturated core). 3 of the 4 bolts in the quadrant are out, as are the height adjustment and thru-bolt for collar. Cables are detached as well. The last bolt is currently going through cycles of PB Blaster and heat along with attack by a 14mm 6pt socket attached to cordless impact driver. Heat applied was by propane torch, and heated until grease on the steering cable caught on fire. (YES, Fire extinguisher is on-hand)
Yesterday I was able to get torque applied with the impact driver. No Joy, but at least I was getting torque and shock load onto the bolt.
Previous failed attempts: (I HATE STAINLESS FASTENERS IN ALUMINUM)
1/2" Drive, 9/16"12pt socket: would slip on head, would not fit without short extension to get head of wrench away from quadrant.
1/2" Drive, 9/16 6pt socket: would not fit on head of fastener. Wall thickness of socket is too big for tight clearance to steering quadrant.
3/8" Drive. 14mm 6pt socket, 3in extension: Would slip off fastener.
9/16 and 14mm open end wrench with pipe extension: Would slip off fastener due to angle required to clear shaft collar.
