[BlindHandyMan] Keeping hand straight when driving nails

[Agent086b]

Hi again all,
I asked the following question the other day in the wrong way and did 
not make myself clear.
When using my palm nailer driving any size nail. How do you keep your 
hand straight? I find as I press down on the nailer I must slightly be 
on an angle as I often bend the nail I am trying to drive or at least 
drive it in on an angle.
thanks for any guidance on this one.
Max.
