Was it worth the effort ? Advice needed...........

I purchased a Sistrum Sub Stand for my Sunfire Sub. The results were utterly astounding. I decided to put Audio Points under the bar stock legs of my Magnepan 1.6's. The removal process and installation of the points went really smooth. Upon assembly one screw from the leg mount swisted off and it will not come out. Kind of cross treaded I guess. With out any warning of a treading problem it just broke off. I put the remainder of the hardware on and set them back up. The sound difference is incredible too. But I noticed that the panel is vibrating from not being secured to the leg structure. So I'm looking for advice as to how to get this broken bolt removed. Help .........please !

It is frozen in position. The screw turns but will not back out of the speaker. Strange like it pulled the treads going into the speaker. I have put vice grips on it and applied pulling pressure at the same time that i'm turning counter clock wise. But it just turns and will not back out. It's like a 3/16" screw in diameter. I have about 3/4" sticking out. What do I try now??????????

If you need to drill and retap the threads, the rule of thumb is to use a drill two sizes smaller. Good luck.

Zenieth,

It sounds as though you have worked yourself into a tough corner. Before you go further, I think I would consult Magnepan, since they know exactly how the speaker is put together and they should have the most insight into this particular problem. I'm sure they've seen this happen more than once...

Sounds like a threaded insert is used and has broken free. Best thing to do is somehow pinch the thread insert in place (so it doesn't rotate) then remove the screw. If you have cross threaded the screw and cannot pinch the thread insert firmly enough you will probably have to perform major surgery by removing the whole insert (could get ugly!). Either way you will have to somehow refasten the threaded insert, perhaps using epoxy. Without pictures it's very difficult to assess, but it sounds like proffesional help could be required to avoid mangling your speaker.

The tread insert is recessed and you can't hold on to it. Maybe a pointed object pushed into the panel beside the insert will help. I have a call into Wendall at Magnepan. I will not attempt anything until I get his thoughts. What a pain in the ***. Something simple turns ugly. I can't win for losing. The forty two inches of snow was bad enough. I was just trying to stay occupied. I should have listened to the rig and not tried to improve it's already awesome sound. Go figure.................I'll keep you posted! Thanks to all of you for your help too!!!!
