e and a strings are often fitted with a plastic sleeve or parchment paper to help prevent it sinking into the bridge. Many are not in favour of these plastic sleeves. In past posts, it seems that someone suggested that an easy way to build up low nut grooves is to fill them with CA glue. If that works, seems to me that dabbing a spot of CA glue into the string slot of a bridge could work well instead of the sleeves or parchment. Any reason why this would not be a good idea?
Thanks, Mat |

I use parchment, glued with CA glue for building up nuts (at times when replacing the nut does not make sense). I don't really like the surface of filed CA glue, and don't know how it would work in the long term. _________________ Leif Luscombe

Thanks Lief... I have been dabbing the bridge slots recently and it seems to work really well.. I don't think it has an effect on the tone. When I apply the CA I wipe it quickly so that there is little buildup, then file with the mousetail file and line it with pencil graphite... so far no problems! |

I am glad to hear that it works for you
I still feel the CA is quite hard and brittle, and that the parchment offers a somewhat softer surface for the the string to glide over. I have seen CA break like glass when under pressure or stress. _________________ Leif Luscombe

Thanks Leif...I was not aware of the brittle factor, but I must say that I have never used CA for build up...I use the original thin version that soaks into the wood so the strings are really resting on the wood.
Good to know though!
Cheers, Mat |

Matt:
I tried CA long ago for RC model airplanes. I found it to be quite brittle
immediately (next day). than after about a year the glue joints were so
brittle that broke like glass. The balsa was rock hard for about 1/2 to 1/4
inch away from the joing from absorbing the glue. You might try making some ultra fine sanding dust (maple) and mixing it with some other types
of glue and try it as a paste filler. You might also try very low viscosity
CA (hobby shop) with the dust and try using the least glue vollume for the
mixture to be a thick paste. As hard as ca is it should still be plenty hard
. There are other glues (like resin glue) but you are stuck with only
using clear ones I guess.
I hate thole little plastic string tubes. They allways get deformed or get
holes.
A good model airplane hobby shop will have 20 different flavors of CA.
