Airsmithing is a trade exclusive to the
paintball world.
Gunsmithing is to firearms as airsmithing is to paintball. Airsmiths spend most of their time behind machine tools such as
mills,
lathes, and other various equipment. Airsmiths are responsible, in large part, for most of the
anodizing or custom work done on
paintball markers.
Some of the more
popular airsmiths include Doc Holiday (http://www.docsmachine.com), Glenn Palmer (well known for his line of aftermarket products for the
Autococker, as well as his many other custom
guns -- http://www.palmer-pursuit.com), etc. Basically, if you want your gun to look
cool, work better, or
fix it, then send it to an airsmith.
