As a matter of fact, No.

>The blade has got a 60/90 degree rip saw profile with an aggressive set. For several reason I can think of, it does seem like an ideal rip saw, so I assume the intention was for resawing. I don't think I have the gumption to neander resaw. I'm thinking about F Klauss'ing it and may look into sticking on a Japanese blade.

Can you translate that into the noprmal Disston jargon of rake and fleam as per Pete Taran's page - I don't underfstand whta you mean by 60/90.

On that web page you reference, if you scroll down to "The rip saw tooth", there's a diagram that shows the "Angles of rip teeth.." filed at 60 degrees from the perpendicular, and 90 degrees from the length.

I haven't measured the fleam angle, but it looks rather aggressive/high.

Yeah, the few cuts I did with it last night did cut quick, but my kerf went all over the place. Thanks for the emotional support. ;-)

OK. I understand. In all western saws sharpened with a triangluar file, the gullets are ALL 60 degrees (same shape as the file :-), and if the filing is does uniformly, ALL the teeth points are 60 degrees.

So it's not usual to bother mentioning it ;-)

The only thing that varies is the angle of the lead face of the tooth. This is what Pete calls the "Rake" angle, and would be described as '0' for the teeth you describe. (the angle of the trailing face is determined by 60 - angle of lead face - diagrams on Pete's page)

An "easy going" rip might be filed at around 4 degrees, whilst cross cuts tend to be in the 10-20 range.

The eBay Marples is indeed called a bow saw, but bow saw is quite a large family. If one were being more careful, it would be called a turning saw, and features a narrow blade. Bow saws of this size and style are used for cutting curved shapes out of boards.

I think the sort of saws Frid refers to have deeper blades, rendering straight cutting easier.
