It's 16mm From: "David Love" <davidlovepianos at comcast.net> To: <caut at ptg.org> Date: 05/27/2010 10:28 AM Subject: Re: [CAUT] Bore distances for Steinway L BTW you can check to see if you matched the new to the old by measuring the center pin to knuckle center dimension. The old one was probably 16 or maybe 15.5.

I'm pretty sure I matched the new flanges/shanks to the old ones (too late to check that now, but I almost always do) The key dip is 10mm. The string heights are as follows A-0 19.7 A#-2 19.7mm B-2 19.1 D-5 19.3 D#-5 19 G-6 18.8 G#-6 18.8 C8 18.8 Paul From: "David Love" <davidlovepianos at comcast.net> To: <caut at ptg.org> Date: 05/27/2010 10:05 AM Subject: Re: [CAUT] Bore distances for Steinway L The proper bore distance is the one you determine by measuring the distance between the flange center pin height and the string height in each section. Check that first. Are you unable to get the let off closer because the let off buttons are bottoming out against the rail? If so then maybe you have the wrong buttons on there. Did you change the shanks and flanges to a new dimension? If so, did you change the dip to accommodate that? What is the current key dip?

What is a proper bore distance for a Steinway L (1924). I installed some Abel Naturals last fall and the project went on hold while the piano got a new board and bridges. I just measured A-0 and it's 2-1/8". I'm trying to regulated the action and am having a tough time for some reason. The key level and dip is factory perfect, I've got the proper blow distance of 1.75". I can't get let off any closer than 1/4"!! The rebuild was done right and the plate is the same height as before. I've even tried to raise the blow a bit, and still can't get it to let off correctly. The frame is perfectly bedded. The wips are old, but in pretty good shape. I started at A-0 and only tried 5-6 notes before writing yall. I'm wondering what's going on. Any thoughts of what to check next?
