Pneumatic finish nailer question - how deep should nails go?

[GirchyGirchy]

Everyone,

This afternoon I installed some crown molding in one of the upstairs bedrooms, using my Bostitch N60 I drug out of the trash a few years ago. It leaked air and needed a new trigger valve, and now appears to need an O-ring kit as well (leaking out the exhuast).

Anyway, I noticed that the nails end up sticking out about 1/8". I'm using 2-1/2" long 15 ga nails, going into (as far as I know) plaster covered with a 1/4" sheet of drywall. For now I'm going back and hitting them with a nailset to sink them in enough to use some putty on the holes.

The compressor's regulator is set at 100 psi, which is the max for the gun. I'm using 1/4" poly hose since it's nice and light, either 35' or 50'.

Any ideas? Only other time I've used this (or any other) gun was messing around in the garage on a 2x4 to test it out, and don't recall this happening.

Thanks for any help-
Brian

That gun should drive them below the surface

Have you played with the depth adjustment? You should have no problem countersinking them at 90 psi, much less 100.

Next time just tell me to RTFM. I found the adjustment screw and (as far as I can tell) set it to drive them in further. Thanks!

We all have days like that

Sounds like a good excuse to me!

I gave it a shot and it seems to be doing the trick - that'll make the other three rooms much easier. Thanks a bunch!

Once you replace the O-Rings you may have to back the depth off some. Once it isn't leaking the current setting may shoot them too deep.

I wondered about that - thanks for the tip!
