Re: Adjustment Screw #12 on Rigoutat RIEC

If there's no adjustment on that linkage (screw #1 in the diagram), then you have to rely on the thickness of the cork on the RH1 key foot/linkage, the RH1 pad thickness and travel (venting) and also bending the long linkage bar (the 'con bar' - short for 'conservatoire bar as only conservatoire systems have this) to get the clearance right.

There has to be some play (only a small amount) between RH1 and the underside of the lower end of the con bar, then when you close RH1 there has to be clearance at the top end of the con bar between the surface of the top joint and also the linkage from the Bb key. The adjusting screw on the linkage from the Bb key allows fine adjustment to get the amount of double action right so RH1 can fully close and also the Bb key on the top joint doesnt remain held open.

It's one of those adjustments you have to go around to make sure the clearances are all fine - you can have as much clearance between the top joint surface and the underside of the upper end of the con bar when RH1 is closed. On dual systems there has to be some cork on the underside of the upper end of the con bar, but there still needs to be some clearance to be sure RH1 can close.
