Hello! I got my hands on a quite old pipe. It's pretty clean overall but is going to need some polishing and probably another bowl of salt before it's ready to be put into use. Is an old William Demuth Milano, Hessian Guard. I think that it is quite old, forty years or more! There is only one problem: the stem fits the tendon quite loosely and rotates almost freely. It does not pull out under it's own weight or with gentle shaking. It comes apart quite easily if two hands are used though. The shank is metal. How do I repair this/tighten the hold? Or do I? I have thought about heating the metal so that it would expand and about soaking the tendon so that it would expand. I don't think either approach would be much more than a temporary fix and I'm not sure that either approach would be a particularly good ida. I'm anxious to try this bad-boy out though and would love to have apiece of Pipe History to call my own!
