Dale, I used an auto body product on a plate several years ago. It was called feather-fill. I sprayed it on with a conventional gun I kept to use for primers and it worked quite well.

Weber grands were made by Young Chang. The action brackets on YC's for many years, for some strange reason, actually expanded, which threw off regulation. YC used to give you four new brackets, but I don't know if they still do that, so give Young Chang a call, and ask if they still give them out. You'll need a serial number of the piano. The customer will have to pay to have new action brackets installed. The latest information I have for Young Chang is: Parts manager at Young Chang John Chang, 866-798-6979 ext. 144 Jchang at ycapiano.com Monica is the receptionist at ext. 0 But I heard that John is no longer there.

Or maybe check first if the spread is way beyond spec. I think they're still providing brackets. At our chapter meeting this week, I talked to a local tech who's encountered a piano with the issue. I don't recall if he said he'd talked to YC yet or not. I think he monitors this list... maybe he'll chime in!?!? Excellent writeup about the problem and the fix in August 2009 Journal.

In the 80's I saw a 4'-something high school vocal music teacher utterly destroy a new Baldwin studio in under a year and a half. We went through three full sets of bass strings, the last a "heavy duty" set supplied by Baldwin, and hands full of individual replacements. She stood at the piano, since she couldn't see over it sitting, and her full straight arm weight went into playing loud enough to be heard over (drown out?) the choir. I'd told her at the first string break that she needed a grand, and a big one, but that wasn't about to happen. The piano finally came back to the store worn out, patched up, and utterly worthless for resale as used. I'm not sure what they did with it, but it sure deserved better. I wish you luck, as it's unlikely to be any fun.

I need some help. Because of the nature of our work we refinish a lot of plates every year. We often get the spray canned special paint job and other times quite a decent finish but aged and other forms of stuff which needs re-whatevering. But right now I have a Stwy B plate & the second finish that was applied previously is very thick and chippy and comes off easily in places and the other half won't no matter what. Trying to sand it makes a hodge podge mess. No matter how well you might feather all the edges it usually ends up showing up even through the new finish. We use acrylic primer and top coats with gold followed by clear coats. I have sand blasted two plates which takes of the Japanning/ porcelain under coat. I hate to go this route but in this case I'm stuck. So... after the blasting it's a matter of using some type of primer to fill and smooth. I'd like to hear from anyone who has suffered in this way So the question is... I would like to find a bare metal sealer/finish that flows and fills and sands easily. My thought is to locate something you can just pour/spray on and let it flow out. Similar to polyester. Get the idea? Hey any ideas welcome Thanks Dale S.

I'd like to hear from anyone who has suffered in this way This was the worst. The topcoat was really hard, flaked off in some spots, hung on like warts in others. I bought a needle scaler from Harbor Freight and hammered the whole mess off. Roughly the equivalent of blasting, but more work. <G> Evercoat Featherfill primer, sand forever, and topcoat as usual. A true pain. > So the question is... I would like to find a bare metal sealer/finish > that flows and fills and sands easily.

Hey any ideas welcome I think you should stick with the blasting, rather than have the pour-on magic elixir stick in some places, and not in others. I'd hate to have to do one of these twice. Or if you feel lucky, maybe a marine epoxy primer, and metal flake gel coat it. I Have ideas, just not necessarily good ones.
