First, I'm a hobby guy. I also don't know everything. You also won't hear me tell my kids that.
I was looking at the Felder and Hammer websites and see a lot of very cool toys. But there's one thing I'm not seeing immediately or I don't understand how they specify it - what is the diameter of the arbor for the saw blade? All of my blades right now are 5/8" diameter. If all I owned was one blade changing to another size if needed would be no problem. But a bunch of them - ouch.
OTOH, I do like the option of using a 10" or 12" diameter blade if I want to. Yeah, I know - who needs a 12" blade if they do this only as a hobby. But my miter saw has that diameter blade, maybe, if need be . . . . .
