Here's an 8ft Simonds 'Royal Chinook' . . . . it's never been 'in wood'.
This is a falling saw, bucking saws were a little deeper with a straight back.
Cardio? you bet!
not yet... was picking up raspberry stalks for my folks and the farmer I was getting them from had a shed full of old saws and that's how I came to own it. I gotta do a full rebuild on it still. Parts for my old 075 stihl came in first so that'll get done first, then the 3120.
After that I'll turn my effort back to an old stihl 200T to make into my new jeep saw
