The Adjusting tool is quite easy to make. You just need a picture of one to get the basic idea of how to fab it up. A piece of 'Flat Bar' 3/8 to 1/2 and inch thick, by 2 inches wide by 4 to 6 inches long. Weld this on to a piece of one inch pipe, lengthwise. Now grind or cut a slot in the flat bar that is the thickness of the sides of the lincs, about 3/16 or an inch. Not much to it. The piece of 1 Inch pipe should be at least 4 or 5 foot long to provide enough leverage.
