Jeannie,
Hold on while me wipe the egg of my face...there!
I must have sounded like Chicken Little..."the sky is falling" with regards
to the stock tip that comes with the Palm Nailer.  I should have never
commented on the tip until I had a chance to use it.  I was simply passing
on what I thought was useful information from the manufacturer.

It does work great right out of the box.
I personally can't find anything wrong with this tip.
I strung a Mason & Hamlin A today and what a pleasure!!!!
  In the meantime I will be calling the tech from Danair and tell him to
stop telling piano rebuilders the stock tip is not suitable.
Very Humbly Yours,

Tom Servinsky,RPT



In the meantime sorry
