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 !

Always try the easiest fix first, which would be use a pair of vise grips to remove the broken off stud. If the piece that the points thread into is removable, you might be able to get to the stud from the other side but I'm not familiar with this set-up. You can also try using a punch or small chisel & using a hammer, work the broken stud out. Depending on the hardness of the metal, you can try hammering a sharp phillips screwdriver into the end. If there's not enough metal to grip, try an easy out. Use the biggest one that will fit.

If an easy fix won't work, you'll have to drill out the stud & either rethread or heli coil the buggered up threads.

Zenith, visit a good hardware store and they will sell you a tool to do this.

If the stud is sticking out, you may be able to put some penetrating lube at the base and then grab the stud with vice-grip pliers and slowly turn it out. Depending on the diameter of the stud, you might also be able to carefully cut a slot into it with a hacksaw blade and then remove it with a screwdriver.

If you remove the whole leg by taking out the remaining good screw, will that expose the broken screw so you can use pliers or vice-grips on it?

If the stud is not sticking out enough to grab or slot, you could drill into it with a small-size bit and use an easy-out (available at hardware stores) to remove it. In the worst case, you can just drill it out (I'd try to use a drill bit just slightly smaller than the stud). If you mutilate the existing threads you may have to rethread the hole, or chase the threads with the correct thread tap. There is also a chance you will need to tap it to a slightly larger diameter in which case, you should first check to see in which thread size and diameter the cones are available...

Since I can't exactly see what you are talking about, (and don't know the size of the screw, bracket, or anything else) the above advice is just my best guess at how to approach this problem. I hope it gives you some good ideas.

Good Luck!
