The family and I visited a mill in OR in the early 90's that used a saw like that. The carriage was semi automated and turned the log, returned it for the next cut until it was squared. then it sent it through until produced all the 2Xs that could come out of the log.
They wouldn't let us in the shop, though. I would have liked to see their sharpening operation.

Now what do they use. Cool blocks or ceramic blocks.

geeze, id hate to have to pay for new blades!

The really cool ones have teeth on both sides so the log can be sawn in both directions! Wow lots of memories there. Ive seen a few saw blades explode and pieces fly all over. Amazing how a small piece of rebar or an old insulator can destroy one of these huge saws in the blink of an eye... real scary thing to see happen...

I heard Norm Abrams was getting one like that for his shop

Hey thanks I thought the teeth on the other side was so they could flip the blade to get twice the life. Never thougth about sawing from the other direction. Which now after thinking about it make perfect sense.
Thanks

I wonder if that be true. What I mean is do we know the metallurgical properties of the steel in the blade is. I would guess the main body is a flexible metal with the teeth portion being more hardened and less flexible. Since I imagine you would use the main body of the blade for knife is flexible a desirable quality?
I readily admit I don't know and that is why I'm asking.
I was always told the best knife blades were made from file steel that was left outside for about a year.

I was thinking about filet knives where flexibility is desirable. I use bandsaw steel for draw scrapers/shapers now and it works great for that.

Of course, that's more steel than I would need for a lifetime of scrapers, but I share

.
Do you know why file steel should be left outside to make a good knife?
