Re: Key Cork Thickness

2mm, 1mm and 0.5mm should be a good start - though natural cork isn't always the best material to use depending on the application, but it will give you an idea of what thickness silencing material to use.

Don't stick a really thick key cork on and then sand it down to a funny shape as it looks untidy - best to use a uniform thickness on the underside of a key as it looks better.

For open standing keys use ultrasuede or a similar soft material. For linkages use a tough material such as gasket cork (rubberised cork).

The only place I tend to use cork on clarinets is on the throat A key stopper, otherwise it's gasket cork and ultrasuede.

Use a good adhesive to stick it on with too, but you should still be able to remove all the adhesive from the surface of the keys when you have to.

And always use a sharp blade to trim with (ie. scalpel or razor blades) - as soon as the blade begins to dull, replace it with a fresh one so you get crisp, clean edges to all your key corks.
