Air Hammer revisited

[Carl Meyer]

Jeannie, Farrel, Tom and all you other air heads, I mean hammer heads, I
mean whoever:

I bought a Danair nailer and then ordered a 7/8 inch sleeve to cover my
intermediate punch that I described.

I talked to the sales manager of Danair and he described the special tip for
Baldwin.

The basic nailer tips plunger is about 1/4 inch in diameter.
The sleeve  in various diameters is spring loaded. Normally the sleeve is
short enough that the nail will be driven below the surface.

Now the problem with the stock sleeve is that you can't see how deep the pin
is being driven.

The modification was to provide a sleeve that was 3/4 inch longer that the
driving piston.  Now you could drive pins to a depth exactly 3/4 inch from
the block or plate.
It had a slot so that the string would be free of the sleeve if you were to
put the coil on the pin before driving.  That would prevent the sleeve from
damaging the wire.

Now consider that you drive the pin in to 3/4 inch height and now you string
with three turns. Further driving with this sleeve is impossible.  You were
limited to 3/4 inch, remember?  You would have to now change the sleeve to
drive the pin deeper.  Not practical!

If you have chipped the piano you need to use the schaff tool no:108 (tuning
pin setter) to prevent the string from going flat.  Just another operation.
Time consuming!

I find that driving the pins to a uniform depth and then stringing with the
instacoiler is accurate and fast.  I can give a step by step description of
the insta coiler procedure I use that works good for me.  Ask me, I'm tired
right now. Good night.
