I wouldn't glue anything but I do think the nut is already glued.
After starting this thread, it was mention ( this question is probably best asked in the Builders Group,) so I posted it there also. Sorry if this has cause a problem but this set up has been nothing but confusing from the start & the members are about the only ones who can give me any advice. And still without knowing anything myself, there is - sent it back, get it fixed for about $100, or just play in the strum hollow - I wish I did know more about building an instrument, so I would at least know best way of dealing with this problem.
Yes, it's very confusing

I would strongly recommend against gluing a shim underneath the nut. Shims are usually considered to be temporary fixes, even if they are left in for many years. Personally, I prefer no glue at all under a nut even when it doesn't have a shim. String tension holds it in place nicely, and nuts are something that people change or adjust fairly frequently, so having it easily removable is convenient.
(Marg, you seem to have started several threads on the same subject in various locations- next time it would be less confusing if you only post one thread per subject or per question... thanks much!)
