cutting mega arbel does suck a big donkeys you know what. It has 4 things that I hate about it. 1: it's hard to measure if you have to butt it up against anything. 2: it's big and heavy so the old saying applies "measure twice cut once" because carrying a piece back to the saw more than once really makes me mad. 3: it takes longer to cut and wears out blades faster because it's thicker. 4: more wasted material.
I almost cringe when a customer wants mega arbel. I have a 175' long sidewalk (4' wide) to do with mega arbel and I'm not looking forward to it. The only good thing about the side walk is that we can cut in place.
