Impressive!

I take it you made the jig, yes?
Political Correctness...defined

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

Re: reattaching loose magnets

Damn, Mike. I would have never even attempted that repair--awesome!

How do you keep the bolts holding the magnet from loosening? Glued?

Vibrations from woofers is a bitch. I kept hearing a buzz from my right speaker last week & looked in back to find one of the banana plug screws was backed almost all the way out~

I learned on a Stark just a little later model than that one(it didn`t have the oilers), it too was belt driven.

Re: reattaching loose magnets

when the pole was centered, I then just gave the bolt a everso slight snug up....
the bolt opp each other is a stop, kinda a push,push action
these only just held onto the outside of the magnet till the glue was dryed

clear as mud...eehh :? :? :D :D :lol: :lol: :lol:
