A friend of mine who happens to be blind asked me to adjust his old Alvarez. The action was pretty high and the saddle was almost depleted so I thought I might try to do a neck reset. As I examined it I realized that at some point hot stick (plastic) glue had been used to fill a gap between the back and the neck block. I fear that the whole thing was attached with this same messy stuff.
What is the best way to dissolve this stuff? I explained to my friend that his instrument may end up being sacrificial because of the process so he bought himself a new guitar and gave me the freedom to give it a try and to give the guitar to someone who needs one if it turns out playable.
I mostly build ukes and have only done one neck removal as a practice project from a clunker someone found in the trash. Got it off ok, but the guitar went back into the trash!
There are a few types of thermoplastic stick glue, many of them can be removed with alcohol.
Thanks, I'll give it a try. What could possibly go wrong?
I have never run into this before but i would speculate that the traditional method of steaming the joint would still remove it since it is a heat sensitive glue. I don't know how runny it becomes with alcohol but you might try doing the steam first to soften and remove the neck and then use the alcohol to clean it up. I am just wondering if the alcohol would cause it to be runny and make clean up on the finished surface a bit more difficult. If you could post your results of what worked and how things turned out that would be great.
