I’m working on a Silvertone with the threaded end of the truss rod broken off. 

I saw your article about the removable truss rod on a Harmony Sovereign, which looks the exact same as this truss rod. I screwed a threaded rod onto the remaining threads, but can not get the truss rod to pull out. It seems very tight in there, and has some corrosion. I had removed some wood under the 1st fret inlay to help get out the bushing, photo included. 

I tried the pistol type soldering iron with two tips to heat up the rod with current flow, but that did not work to warm it up. If I access the rod at the other end also, is there a better device to heat the rod, probably using current also?

Any other suggestions?

If it's one of those double rod things, it can be really hard to pull, what with rust all along the length.  If you can screw a rod onto the end, then, you can rig up a slide hammer kind of deal to tap it out.   Likely it would need hundreds of solid blows to draw it a fraction of an inch at a time.

I do have a rod screwed onto the end now, the slide hammer system sounds like a good suggestion.  Thanks for the reply.  I'll keep at it then.


Probably faster to take of the fingerboard.
