I broke one of my chain plates last fall while sailing. Fortunately there was no other damage since we were able to turn into the wind
and drop the sails
to a nearby marina.
I've done a lot of work on aircraft, car and tractors but am new to boats. I took off two of chain plates the long one of the mid side plate and the broken short one a rear side plate. I delivered these two chain plates to a nearby machine shop to make new plates.
I have received the new chain plates back and am ready to install them.
During the removal
of the plates I "spun" galled I believe two of the bolts one on each chain plate. I am now putting a lot of penetrating oil
on the bolts of plates still to be removed.
I'm trying to figure out how to remove the "Spun" bolts. These are internally mounted chain plates. They are on fiberglass
"knees" I believe they called. There is a nut plate behind the "knee" that is inaccessible. The bolts are long enough that they have threads that extend behind the nuts. The result is the bolts spin but don't come out of the hole. I ground the heads off to get the plates out.
I have not been able to figure out how to remove these nuts. I have not tried to drill them out. Dose anybody have any suggestions how I can best get these bolts out?
I plan to replace these bolts after they are removed by tapping out new threads and replacing with slightly larger stainless bolts. Am I on the right track here?
