When I made my first comment in this thread I was thinking of starting from scratch, as that is what I do most often. In the field though, I most often find its just a bedding bolt check I'm performing and accomplish it quickly in the way you describe as it is expedient and..... unnecessary to use the other protocol. If I am doing work in the home and have everything off to clean and inspect it, I would do it the first way as Al said. There w e go 2 cats skinned in differing ways for different reason. I love this work. I try to never go home the same way twice too.:) Dale S. Erwin www.Erwinspiano.com Why would I remove the stack and keys to regulate the piano? Unless I’m leveling the keys from scratch I perform all regulating procedureswith the action assembled and that includes even minor changes in the keyleveling.. I’m just offering this as another wayto approach it whichever way people want to do it is fine with me.

But if you are not regulating the piano,there is nothing wrong with fitting the frame with the keys on. I do itall the time.

I think we're having a hard time with the word"contrarian". So let me restate. Contrary to those who advocate forbedding the keyframe with the stack and keys removed I prefer to do it with theaction assembled. Of course I don't think there's anything wrong with eithermethod. I do think thatgoing to the trouble of removing stack and keys is unnecessary.

The only time Ibed the frame with the stack and no keys is when Ihave a piano in my shop and I'm doing a regulating. Al - High Point, NC From: DavidLove Sent: Saturday, October16, 2010 1:08 AM To: pianotech at ptg.org Subject: Re: [pianotech] wascurve now glide It’s contrarian in that the others were advocating bedding thekeyframe with keys and stack removed. I see no particular advantage indoing it that way and in the field it’s not practical. I suppose youshould check the una corda bedding but if it’s different what do you do? I would opt for the bedding with the key set in the rest position.

It's just the same procedure with theentire assembly together. The advantage of achieving positive contact with the keys off,then loading them on after, is to insure that the flex of the keybed with pedaluse doesn't "unbed" the center even by the slightest. No-one has addressed shift-bedding (una corda). There can be veryslight variations across the surface of the bed where the glide contacts it,and it is wise to check the una corda position bedding as well. Minor detail.

The technique I use was presented bySteinway’s John Patton at one of the conventions. Can be done in acouple of minutes or less on a Steinway. Pianos that have glides that areburied underneath the keys require at least the removal of the covering keysnaturally. The process is simple and requires you to just back off theglides enough to be sure that none are touching the keybed which you can testbe pressing down on the glide bolt with a wrench (or a screw driver if it’s ascrew type) using the back of your hand against the pinblock as leverage. You will be able to see the keys flex downward when there is a spacethere. When they all produce a bit of flex then start in the center andturn each bolt down until there is no flex, backing it off just slightly inorder to produce that telltale knock and then just setting the bolt down to eliminatethe knock/flex. Go alternately outward until all are bedded. Thengo back to the center and make sure you haven’t “unbedded” the center glides byturning the outer bolts down too far. If you have then start over. It requires a bit of touch and sensitivity but it can be done quickly andaccurately with some practice. -------------- next part -------------- An HTML attachment was scrubbed...
