The only one that is tough to find is .050" (or is that 051"?) but the rest are normal string sizes. Straighten the wire by pulling it through a hole in a 2x4 (or whatever). Cut a 5" length and chuck it into a drill. Spin it slowly with the drill while holding the tip against a belt or disk sander at an angle to create a sharp point. Smooth and buff the point after it is sharp. Then put the wire on a workbench, and with the edge of a large file, create a 1/2" wide rough area about 4" in from the tip. Apply a lot of pressure with the edge of the file, and change the angle around so that the rough area is evenly rough, about like 220 grip sandpaper or so. Put the wire into a center pin vice (the little handles that can be bought from supply houses) or glue it into a wood handle, and voila', a very nice center pin broach. The rough area must be 1/2" or more from the handle, so that the bushings pass all the way over the rough area twice with each reaming. Since Schaff is set up to make them, I think it's easier to just buy a set. I'd feel so even more strongly if they paid me something for them .. . . My main complaint with using center pins as reamers is that they don't stay sharp, and each time you make a new one it cuts a little differently. Hammer centers especially need to be consistent in friction, and hard steel reamers make this much easier to accomplish, especially if you are burnishing the bushing to smooth it during the reaming process. You can dig up my old article from the October '88 Journal to get the full description of how to use this type of broach. Motorized burnishing works pretty well if it's not spinning too fast as mentioned by Horace, but if this is used to enlarge the hole much it tends to generate too much heat, and the bushing will sometimes tighten back up again.
