Re: Alternative key materials

While carbon fibre is good stuff in some applications, the resin used to bond it is the problem if using any kind of thermosetting glues to install pads as that will melt with the heat.

Keys will have to be made so everything lines up perfectly (pad sets, linkages, touchpieces, key feet, etc.) as you can't bend carbon fibre to make fine or any significant adjustments as you can with metal keywork as carbon fibre will just spring back to its original form as it behaves in an elastic way rather than in a plastic way as metal does once bent past its elastic state.

Threading carbon fibre for adjusting screws isn't easy (I've tried it). You'll need to install metal or plastic bushings for the adjusting screw pips or fart-arse around sanding down key corks or fitting shims to get the adjustments right.
