Hint for fitting bridge!

posted Feb 07, 2014 16:38:05 by SteveTebble
I'm about to fit a new bridge to my Chibson and have bought a Gotoh Nashville-type, with the correct metric studs. My problem is that the studs are very slightly smaller in diameter than those they are replacing. The one on the treble side can be pushed in under finger pressure, and pulled out easily in the same way. On the bass side the position is even worse; it just drops in and, if you turn the guitar upside down, drops out again! Admittedly all will be held in position by string tension, but I wasn't sure it was a good thing for the studs to be this loose so called my local luthier and explained the problem.
He agreed it shouldn't be this loose. I asked if it would be permissible to just wrap a turn or two of masking tape round each stud before tapping them in and he said some might do it that way, but a better solution would be to get some of the gel-type superglue and smear it round the inside of each hole, until the hole was small enough for the stud to be tapped in. (He said you could just glue both studs in, but they then would be difficult to remove; you'd have to heat them with a soldering iron to get them out again.)
So I'm going out now to buy some gel-type superglue and will let you know how I get on!

Do you mean the bushings/anchors are loose? The studs screw into the bushings and the bushings press into the guitar body. If you got the Gotoh with metric studs, why didn't you just use your original bushings?

Bushings actually come in different diameters. I was converting a Epiphone LP Special for a friend from chrome hardware to black. I was using parts from my bin so the project wouldn't cost her much. I had swapped a couple of black Epi bridges on my own Epis with Tonepros, so I had their bushings and posts floating in the bin. When I went to swap the bushings, I found that the Tonepros bushings were considerably smaller than the Epi bushings. As you say, they would just drop in and fall out. Decided to leave her original chrome bushings and just screw in the black posts, which hide them for the most part.

The glue idea sounds good though - much easier than filling the holes with dowel and redrilling them.

Of course, what ever you do just make sure you keep a good electrical connection to your bridge ground wire.

If you have some copper shielding tape,then cut to size and wrap around the splines on the bushes,it will then be metal on metal.If you do use this method keep the tape 5mm below the bush flange because when you refit it will push the tape upwards,then you have to remove the excess,so it is best to start lower down the bush.
OTHER METHODS ARE AVAILABE

Copper shielding tape is great - but check to make sure the glue is conductive. I've purchased some where it was and some where it wasn't. Just cut two small pieces and overlap them on a piece of paper. Touch the leads of your meter to each piece (checking for continuity.) If the meter beeps, you are good.

In the event that it isn't conductive, just take a tiny bit of the lower edge and fold it over, sticking it to itself. That will give you a ring that will be contacting the post that is conductive to the outside of the copper foil.

And once installed, check the continuity again just to be sure (touch the lead to the post and the other to the inside of the jack or any of the other grounded parts of the guitar.)

Might be easier to use the original bushings come to think of it!


Edited to add ('cos I just read the posts above):
What about aluminium foil instead of copper tape? That has no adhesive on it.

Use aluminium foil or PTFE tape it will hold the bushes in place. Once they are in they cannot come out as the tension on the bridge will keep them tight,or as you have suggested use the original bushes.

Reason I don't really want to use the original bushes, is because I shall then have to use the original studs (as these are 6mm, those on the Gotoh are 8mm) and they are of such poor quality that the slots on top are already beginning to look a little secondhand, even though I've only adjusted them a couple of times.

If you cannot fix this problem by the above methods ie tape,then the best I can do is send some Chinese 8mm studs and bushes to you.Seeing you are in contact with CGS he will pass on my email address to you.By using my log in name on this forum he will know who I am.
That is the best I can offer you.

That's very kind vambostrausser but first I will try the aluminium foil method; if it doesn't work I'll report back!

No problem, but do check the bridge is grounded afterwards.

Did you manage to sort the bridge bush problem out.

Think so, I'm going to try winding a few turns of aly foil round the bushes, but I just checked in the kitchen and I'm all out of it so I'll need to buy some more tomorrow.

In the meantime I'm going to finish the wiring.

If you are going by a garden centre get some copper SLUG tape.

Metal tape (not necessarily copper) would still probably be a better material than aluminum foil - so long as you check to make sure the adhesive on the tape conducts electricity (for the bridge ground to work properly.)
