(carpentry) Apunch that drives in a nail so that itshead is level with or below the surface.
1939 July, Albert W. Stein,Popular Science, volume135, number 1:
In an emergency anail set can be made in a few minutes from a tenpenny or other large nail. Cut off the point with hack saw or grinding wheel, clamp the nail in the vise, indent the end by tapping it with a center punch, and taper or bevel the end on the grinding wheel as shown.
Throw away a damaged nail set. It's cheap enough to replace, and there's no reason to destroy a piece of molding with a damagednail set that slips off the mark.
2007, David Thiel,I Can Do That! Woodworking Projects:
The tool to do this is anail set, which is essentially a pointy steel rod.
