Oh, but I do! I have been pinning this way for a long time. It is fast,
consistant, and matches the friction to the load. It takes about 90 minutes
to repin a complete hammer line and for concert work, is a no-brainer.
I am tuning a piano this a.m. that I repinned in 1983. I did it in the
winter, and pinned the whole hammerline to swing 6 times, (I keep records on
the school's repair work). It has been used a lot over the decades. Last week,
I found that 90% of the hammerflanges are still between 6 and 7 swings. Two
or three were loose as all get out, and one was tight.
Consistancy is where its at in pinning. Pinning by swing can produce as
consistant a "friction line" as any method I have tried and is faster on the
bench than any of the others. What's not to like?.
