jaycee Posted June 8, 2008 Report Posted June 8, 2008 I have a u channel truss rod, and have just received a carbon fibre square ( oblong )profiled rod. Do you reccomend that I glue the cf rod in place, if so what is the best adhesive to use. I am building a 12 string so I wanted the xtra stiffness (if only for peace of mind) that the cf ros will give. My guess is to use an epoxy resin on the rod Quote
zyonsdream Posted June 8, 2008 Report Posted June 8, 2008 I always use PVC gasket maker when my truss rods but I glue my CF rods with regular Elmers wood glue. If you don't glue it you risk it vibrating on you and causing issues. PVC would eliminate the vibration. Quote
Myka Guitars Posted June 8, 2008 Report Posted June 8, 2008 If you want to use the carbon fiber rods for structural reinforcement then I recommend epoxy. If you do use wood glue remember that the surface of CF is smooth and wood glue will not mechanically bond with it unless you roughen the surface. I find that this is not necessary with epoxy. ~David Quote

Mattia Posted June 9, 2008 Report Posted June 9, 2008 Wood glue barely bonds with CF at all, no matter what you do. Epoxy or polyurethane glue here. Both work. As does (thick) CA glue, for that matter. The advantage to epoxy is that it doesn't matter if some gets left on the gluing surface, at least not if you're gluing the fingerboard on with epoxy. Quote
