Re: Mechanism for half hole of english horn

With the lower plate and C key, make sure the LH1 pad is reasonably thick (but still allows the full venting of 2mm if you like it to be fully open) and the C key pad is thin (almost level with the lower edge of the pad cup) so the C key doesn't clatter against the underside of the lower plate.

But most makers will allow for plenty of clearance here - the C tonehole bedplace is usually recessed deeply into the top joint to allow the C key to sit very low beneath the lower plate and still have the proper venting.

If there's enough room (clearance in between the C key and underside of the lower plate) when the lower plate is closed and the C key is open, cover the underside of the lower plate with a piece of thin cork (as thin as you can trim it). Over time the lower plate can bend downwards and this prevents any metal against metal noise that can happen.
