I'm building a wall using 2x4s. The nails I have are too short, but I
only need about 2 pounds of nails and I have 5 pounds. Should I just cut
the tips off half the nails and attach them to the other (uncut) nails?

If so, should I weld them to the other nails, or can I just duct tape
them on? Or would super glue or epoxy work better to attach the tips to
the nails.

....cut the heads-off and use a brad punch to set them deeper.
