Hi, there was a post recently started by Walter regarding the best glues for certain guitar repair and/or building tasks. I came across this photo of a job I had some time ago where epoxy was used to re-glue this bridge by somebody.
I could not get the glue to give way using heat, not without damaging the guitar anyway, so I had to plane it off. The picture shows the old bridge and the new replacement one.
from the pic it looks like the bridge was largely glued over the finish?
what did you use for the replacement bridge? for a long time now i've defaulted to hot hide glue for bridges, both for reversibility and for creep resistance
Hi. This job was so long ago that I have forgotten the details, but going by the details in the story below I would not be surprised if the bridge was glued to lacquer.
Short story...]I hope]
In the mid to late 1970s, I was doing a lot of work on Ovation guitars, [ where I learned how not to build guitars] I contacted the manufacturer to find out what glue they used in their guitars, but they declined to share that info.
However, long story short, a visitor from interstate to my workshop happened to be a scientist and when I told him of the glue problem, he offered to research it for me.
What I did not expect was to get, in the mail, a full breakdown of the contents of that glue. I did not understand a word except for the last couple of lines, " This is a construction adhesive and I would suggest not suitable for guitar building. It would normally be applied using a caulking gun".
I just went looking for that report and found a letter from Ovation Instruments dated 1975 requesting my services as a warranty repair agent.
in a similar vein, when i went looking for the right glue to reattach those artificial ebony bridges to those artificial wood tops on X-series martins, it turns out they use a special CA glue from 3M called PR600, with a 2oz bottle selling on amazon for like $250!
so yeah, i totally didn't buy any
They used a LOT of epoxy, especially in the Celebrity series and such...
