Though the cam clamp its cute, its really not necessary, and I wouldn't bother making the cams again...they are handy in some ways but a pain in others. Their biggest drawbacks (2) are: 1 the range of overall key thickness they will accept is very limited, so you need to make dedicated cauls for different key thicknesses, and 2 you have to be careful when applying the cam pressure that the key doesn't scooge around on the keytop. By the way, the amount of clamping pressure the cam needs to apply is really not that great in my opinion, enough to get good squeeze out and contact, but in my opinion, that's all. David Love's simpler spring clamps should work just fine. The only change I would make to that system if I made it would be to raise the clamp bar so you could fit a relieved caul under the clamp. A relieved caul does not contact the key in the center portion of the key, only at the ends. That way the pressure applied by the spring at the center of the key is actually applied at the front and back of the key/keytop not the middle. If anyone wants detail photos of my cam and relieved caul setup I'll be happy to post some...but I don't think the cams are really necessary. Jim I Grandpianosolutions.com(almost launched)
