In the process of rebuilding a petite baby grand (1935, 4'6" Gulbransen). When I disassembled the strings, the pegs felt pretty decent/secure to me. I saw no signs of cracking on the peg board and the piano was largely in tune in spite of having set on it's side in a warehouse with no climate control for about a decade (back east with plenty of humidity and temperature swings).
My understanding is that when you restring that you should increase the pin size. The originals were 2/0. I bought some 3/0 - but now the questions:
1) Do I need to ream these out prior to putting in the larger pins? Was I wrong to increase the pin size - i.e. should I try with some 2/0 pins instead?
2) Do you really hammer these in place (to get them in the rough spot first) or is it better to twist them down?
3) How should I align these prior to turning on the 3ish turns of wire?
4) Is there a video or technique that is recommended? I see some people pre-bending the wire on a mock peg first. I can also imagine just bending the first part and then wrapping on the string as I screw in the peg.
I understand that golfing gloves are the preferred hand protection. Anything else that I should keep in mind?
Thanks in advance for your tips!
Reaming is unnecessary, and may be detrimental. 3/0 pins are fine if the pin block holds tuning well on every note, as long as all the pins are 2/0.
I have tried installing the pins first, but wrapping the wire on the pin before hammering it in works better.
If you are regular in cutting the wire to length, the wraps should be fairly uniform.
I use canvas gloves to protect the strings.
People who cannot tune pianos with larger pins should learn how to tune.
