tune, chip with oversized pins?

[Willem Blees]

Daniel



I would suggest?replacing about 4 notes worth of pins at a time. Bring those notes up to pitch, and do the next 4 notes. You're going to?have to retune the piano like you would do a pitch raise, though, so?go over it at least twice, and maybe a third time. As was suggested, you're most likely going to have beckets break?in the lower bass notes. Therefore, I would highly recommend you talk the customer into a new set of bass strings. 

Don't give a set figure for all this work. Estimate a range that will cover for any unforeseen problems, like?broken strings, pins that are very difficult to get out, damper adjustments.?etc. Speaking of which, you should remove the dampers when repinning, especially in the bass. 

Good luck

hi all

?

i looked for about thirty minutes in the archives for info on this topic, but i didn't find an answer and i didn't want to wade through 336 more results from google...

i'm drawing up an estimate for someone and i need to know how many tunings to include.

so i'm looking in the "G" piano works labor guide for installing an entire set of oversized pins, and it says it includes one tuning. now i guess i can understand only needing a tuning and maybe a pitch adjust if you replace and pull up-to-pitch one pin at a time as you go. but it seems that one-atta-time is slower than all-at-once gang style. 

if you replaced all the pins gang style, you'd need to chip and tune?a few?times right?

i think the question i need answered most is if i do it one at a time, which i can do pretty quickly, is the tuning going to end up pretty close to pitch when I'm done?

?

thanks all
