Hands-on human-scale farming will frequently put you in need of a way to repair implements and equipment, including gates, hinges, hangers and such. Success with your operation may well hinge on your willingness and ability to do most of these jobs yourself. Fifty+ years ago, when I got started farming, I was immediately intimidated by the cautions and precautions implicit with welding, either oxy or stick (arc). My first sense was that this process was not for the beginner or novice. I got over my trepidations. That was a long time ago. Since then innovations in welding technologies have come a very long way, adding to the hazards, and complexity, tenfold.
Whether a farmer can afford a forge and anvil will depend upon the distance to a blacksmith shop, the amount of forging and other smithing work he needs to have done, and his ability as a mechanic. Although not every farmer can profitably own blacksmithing equipment, many farmers can. If a farmer cannot, he should remember that a great variety of repairs can be made with the use of only a few simple cold-metal working tools.
One of the main advantages of having a forge in the farm shop is to be able to redress and make and temper tools like cold chisels, punches, screw drivers, picks, and wrecking bars. Tool steel for making cold chisels and punches and similar tools may be bought from a blacksmith or ordered through a hardware store; or it may be secured from parts of old machines, such as hay-rake teeth, pitchfork tines, and axles and drive shafts from old automobiles.
