How to Make a Plow Shared and Landside
HOW TO MAKE A PLOW SHARED
There are two kinds of shares: lip shares and bar shares, and they must be treated differently. We will first treat of bar shares. The first thing to do when a plow is brought for a new lay is to look over the condition of the landside, By landside is meant the bar to which the share is welded. Now if this bar is worn down so that you think it too weak to stand for a new share, then make a new one.
HOW TO MAKE A LANDSIDE
For a 14-inch plow take 2 1/2 X 3/8, or 2 1/2 x 7/16. For a 16-inch plow, use 2 1/2 x 7/16 or 3 x 7/16 common iron. Cut the iron diagonally at the point. This will prepare a point on each side of the cut; that is, you had better cut out two landsides at a time. But if you do not want to do that, then cut the iron off square, Next take a piece of common iron 3 x 3 x 1/4, 13 inches long for a shin; cut this diagonally, and it will make shins for two. Some plow factories use steel for shins, but that is not necessary, for it will not make the plowshare any better, but, on the other hand, will be quite a bother when you want to drill a hole for a fin coulter if ' it is hardened. Place this shin on the land side of the landside, and weld. In preparing the shoulder of the shin for the plate use a ship up setter.
See NO.3, Figure 8. Not one out of 500 blacksmiths have this tool. Every smith should have one. You cannot do a good and quick job without it. When you shape the point of the landside hold it vertical, that is, the edge straight up and down, or plumb. If you don't do this, there will be trouble in welding, especially if you have held it under. Then it will lean under the square when welded, and in such a case it is hard to get a good weld, and if you do you will break it up when you attempt to set it to the square. Another thing, don't make much slant on the landside up at the joint, for, if you do, you can never weld the share good up there. Give more slant towards the point. Be sure to have the right curve. It is very important to have the lands idea right: I, because it is the foundation for the plow; 2, if the landside is right the start is right, and then there is no trouble to get the share right. When finished place the old landside on top of the new, with the upper edges even; don't go by the bottom edges, as they are worn.
