I mis-spoke earlier. The large diameter Tormek wheel leaves a Smaller (narrower) edge bevel than the TAS, but if you are Very Exact setting the edge angle, it's negligible.
Mr. Ken, do you know of CBN wheels for the TAS?? I haven't even needed to dress my plain-jane wheel in years, but I've been planning to get a diamond wheel when the need arose. I would rather use a more forgiving CBN wheel (with very slightly radiused corners).
If you can maintain the factory, convex, primary zero grind of hair scissors with a belt machine, you have No problems. I do it edge up (edge leading), freehand on a slack belt, so I can see. It's easy to maintain the factory "twist" that some people spend thousands of dollars to do with a jig. This only comes into play with hair scissors, and only when the hollow ground primary bevel of the TAS or Tormek becomes obvious.
I'm not surprised the TAS is most popular in Mr. Max's circle. Used properly, it does work amazingly well. Yes, it's trickier using a high speed, 1/2" wide wheel than a low speed, 1.5" wide, water cooled wheel, but there's a LOT of give and take involved.
It's worth saying that there is one thing that makes a big difference for me. I always get the arms of the TAS positioned, then make a false pass. Every time. This assures the arms are positioned perfectly for a straight grind, and you know exactly what it's going to feel like. This way I never make a wobble, so I never make more than one, light, true grind.
