Don, It will be one of the alternatives offered. But since she specifically asked about a "soft close", I want to include info on that also. I would really like to know what QRS has, how it works, and what it costs. Anybody? thanks, Mike PS One of my really big pet peeves is merchants who, when I ask for what I know I want, try to steer me towards something else before they've given me any info on the product I asked for. So I will not do that to my customer. ----- Original Message ----- From: "Don" <pianotuna@accesscomm.ca> To: "Pianotech" <pianotech@ptg.org> Sent: Tuesday, April 22, 2003 7:24 AM Subject: Re: yamaha "soft close" > Hi Mike, > > I'm sure it would be cheaper to devise a clamp to keep the fall board *open*. > > At 05:52 AM 4/22/2003 -0500, you wrote: > >Paul, > > > >I have a client interested in a soft close retrofit to her Kawai grand > >(teacher whose younger students keep knocking the fallboard down on their > >fingers!).
