[Rhodes22-list] removing tabernacle - using heat to remove 5200

[Michael D. Weisner]

Graham,

" Today if I were faced with this problem I would rely on Debond and then track down the person who used the 5200 and hold his head under water for awhile."

You are truly a gentleman. I can't begin to tell you what I would do to such a person.

I had the situation Luis described when I had to remove the centerboard cap back in about 1996. I realize now that it had been installed with 5200 or equivalent but didn't know about that stuff back then. I managed to get it off by heating a large knife to red hot and inserting it into the sealant and slowly slicing along the length of the joint. It worked but took forever as I had to reheat the knife after about a minute and could make very little progress in that time. It was a huge effort. Even so I broke the cap in two in the process. 

I didn't try to heat the fiberglass directly and would be very reluctant to do that now as I think it unlikely that you could get sufficient heat into the join without destroying the fiberglass. It was a huge miserable job. Today if I were faced with this problem I would rely on Debond and then track down the person who used the 5200 and hold his head under water for awhile.

When I was trying to remove a centerboard cap on my first Rhodes, I think it was a 72, I was told that heat works pretty good in softening 5200.  I believe it was an engineer from 3M who told me that. I have to look at he very old emails to see if I can find it. 

He told me to heat up the joint with a heat gun, careful not to set the fiberglass on fire, and work a knife in between to separate.

I did not try that as I was afraid I was going to st the boat on fire.
