Whats the best way to get the most consistent cuts? For example. I have a homemade miter box style cutter that I made. When I made it, I used my hand saw to create the channel that the soap cutter travels through to cut the soap. Unfortunately, the kerf of my saw (and most saws) is larger than the thickness of the soap knife. So what I wind up with is 12 bars of soap that are all somewhat different in size. This is fine until you try to label them. If you do a cigar band style label, you center the front, then by the time you get to the back, you're not centered any longer. Because your bars are all slightly different in size (typically only 1/16 of an inch or less). I'm sure one of those fancy 12 wire cutters would do the trick, but any other methods to get a consistent cut every time?
