I've been cutting glass to put into old factory windows that I am building into the house.
Having fair success, using a cheap Fletcher steel-wheel cutter, with a wheel a little under 5/32" diameter. Dip it in kerosene for each cut. Usually. I can understand the kerosene lubricating that tiny axle, but it seems the lubed cuts part more easily, as if the kerosene does something to the glass. Invades microcracks?
I want to learn more detals about the process. For instance, I have a nearly identical cutter with a wheel a little under 7/32", that will hardly score at all. I sharpened the wheel until it looks about as sharp as the other, still no good. I understand the larger wheel will not concentrate pressure as well, but they made it that way...What am I missing?
Dies the process work simply by adding a stress-raiser, or does the crushing action leave residual compressive stress, or is something else going on?
Would a scratch from a carbide scriber or diamond grinding-wheel dresser work better, or worse?
I am sure somebody in this amazing brotherhood of skill and knowledge has investigated this...
