Thanks Chuck, I have not read your articles- are they in the journal and if so- which issue/s? Thanks again Zoe _____ From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of Chuck Behm Sent: July 10, 2010 4:25 AM To: pianotech at ptg.org Subject: Re: [pianotech] Pin block fitting >Also- when working to fit a new pin block using the chalk method- is it just with experience that you know which chalk marks to file and which to leave? Thanks a million Zoe< Zoe = The chalk marks are the high spots and all need filing off. Make sure you're grinding off wood, and not just removing chalk. It will take repeated sessions to do a good job of. Do have a good vise to secure the block when your filing it? Two woodworking vises, one on either end of the block, work best. Just cheap ones, like you can find at Lowes, for example, work well for this. Also, make sure that the block isn't rocking, but is firmly seated each time you chalk the flange and tap it with a mallet. If it does start to rock at all, you have a high spot in the middle. Filing off the spots that are touch on either end will compound the problem, and just make the rocking worse. Did you read the series I wrote on this last fall? Just this last week I had Dave (the guy that helps in my shop) do a pinblock on his own with no help from me. I gave him the articles, and told him to keep reading until he figured it out, but that I wouldn't answer any questions unless he was asking something that the articles didn't cover. The only problem he had was that at first, he was grinding too much material off from the high spots, and was ending up with a ripple effect. Once he straightened that out, it turned out fine. Good luck with this. If you have a little patience, you can make the block fit the flange like a glove. Chuck -------------- next part -------------- An HTML attachment was scrubbed...
