It looks like the top is destroyed so why not remove the fingerboard and replace the trussrot with a new one.
I'm working on a 1930's epiphone archtop which I think is an Olympic model. The truss rod is, for all intents and purposes non functional, even though there is nothing wrong with it. The finger board is pretty thin and the neck has a forward bow even with the truss rod as tight as I can possibly get it. My plan is to replace the finger board and the truss rod with one of the double action rods that Allied Lutherie sells. I would appreciate any thoughts on this. Anyone ever try to remove the original truss rod from one of these?
I included a couple of photos of this truss rod setup in case you haven't seen this before.
Hugh, Thanks for posting. This has been sitting on the bench all week while I think about what to do with it. I'm thinking that it would be better (and less work) not to replace the truss since it isn't broken and 'functions' as it did when it was new. Also, that is a pretty hefty piece of rod in there and it should keep the neck rigid even if you can't really move the neck with it. I'll try your drum key idea since I have all of the same technology in my shop :)
Thanks Brad, I think that is best way to handle these old Epi's... I literally have about 5 of them at my shop that need all types of repairs. Frank's initial comments about "easily" being in the Epiphone dictionary was spot on. Thanks again.
