Robertson screws are the Sony Betamax of screw-dom. Superior results, but nobody uses them because nobody has the driver because nobody uses them. I first encountered them in a Steinway that had been overhauled in Canada. Needless to say, I was dismayed at the first service call, but when I brought the action in for re-overhaul, I bought a driver and loved the feel. I also replaced them with slotted screws for the next American technician. Isn't that sad? Sigh. Bob Davis -------------- next part -------------- An HTML attachment was scrubbed...
