Air Hammer

[Farrell]

Hello guys!

 "you didn't say what was wrong with the original tips and why they can't be
used as-is." The tip that comes with the nailer appears to me to be perfect.
I used it just as-is and it worked perfect.

Like I said in a previous post: I put the coils on the pins before driving.
No problem with as-is tip. Obviously then, there will be no problem if you
drive the pins first and then put coils on and then wish to even up coil
heights.

Can anyone tell me why they think the tip that comes with the Daniar Nailer
does not work just fine out of the box?

Hey, I just ran out to my shop to see exactly how the nailer tip sits atop a
tuning pin. I put it on a coiled pin and pressed down, but of course because
the air pressure was not on, the tip compresses and kinda thuds to a
collapsed state - quite unlike when hooked up to an air supply. Anyway, in
this condition, the collar does go down to the coil and actually rests upon
the coil. I guess I have to say that I don't know exactly how it rides the
pin top during use. But I can say that I pounded a couple hundred pins with
string coils into a pin block with complete success using the tip as it came
with the Nailer as-is.
