Figure 67.—Pipe-Wrench. This type of wrench is valuable for working with the heavier farm implements. It is intended more for holding than for turning. It is rather rough on nuts. Damaged nuts show signs of careless work.
There should be a good pipe vise that will hold any size pipe up to three inches. At least two pipe wrenches are needed and they should be adjustable from one-quarter-inch up to two-inch pipe.
We must remember that water pipe sizes mean inside measurements. One-inch pipe is about one and one-quarter inches outside diameter. Three-quarter-inch pipe is about one inch outside. Two-inch pipe will carry four times as much water as one-inch pipe, under the rule “doubling the diameter increases the capacity four times.”

The three-wheel pipe cutter works quickly and is satisfactory for most jobs. Sometimes two of the knife wheels are removed and rollers substituted to prevent raising a burr on the end of the pipe.
Threading dies are made in standard sizes. A good farm set consists of stock and dies to thread all the different sizes of pipe from one-quarter inch to one inch, inclusive. Not many pipes larger than inch are threaded on the farm. They are cut to the proper lengths in the farm shop and the threads are cut in town.
