![]() ![]() On a table or ripsaw, this negative hook design means that the wood will come flying back at theoperator. If we used anegative hook, the saw is pushing the wood away from the saw. We woulduse a positive hook blade on a table saw for example or a rip saw. Finally, if thebase of the tooth protrudes beyond the radius line slightly, then we say thatthe saw has a negative hook.Ī saw with a positive hook will betrying to pull itself into the wood (or pull the wood into the saw). If the line and the tooth do not have a gap but line up togetherperfectly, then we say that the tooth has zero degrees of hook. The hook angle is theangle between the tooth and the line, which might be on the order of 10 degreesor more. Is there a slight gap between the bottom of the tooth and the line? Ifso, then we say that this saw has a positive hook angle. ![]() Then, lookclosely at how the bottom of the tooth (about ¼ inch below the tip is located with respect to this radiusline. Start by drawing a straight line from the tip of thetooth to the center of the blade (we would call this line a radius). Let me give you a littlebackground information. I suspect you are usinga saw designed for a table saw you need a blade designed for a radial arm saw.Using the wrong blade is a safety issue indeed. Q: What blade do you suggest for a radial arm saw so the saw does not pull into the wood being cut so much?Ī: If the saw is pulling into the wood,then you are using an incorrect saw blade for this saw. ![]()
