NH:

I will ask them about saw blade angle. I'm going to be there this weekend in fact.

Angle would be an easy way to tell the difference between band and sash/muley sawn boards.

That's interesting that you say the muley saws were newer innovations from sash. From my reading on the subject, a more efficient method was what the industry always strived for. A fat blade on a muley would waste alot of log. But perhaps it was more reliable than its thinner sash cousin...less breakage, downtime, etc.

One book talks about band being preferred over sash because of the waste issue. Though sash blades was thinner than muley, it wasn't as thin as band...

What's your take on that?

Thanks for the info!
