Buzz saw tooth set ?

Mr. T. Minnesota · Jan 30, 2015

Forum Members,
While blocking firewood with the Dearborn buzz saw the past few days I decided to add set to the teeth. Question is how much set should there be in the blade? Second novice question-why do the teeth seem to lose set when the teeth are not worn significantly? Any and all thoughts are welcome!

the more set the bigger slice of material removed..

Some set is filed off each time you sharpen the blade? I just do it by guess and only enough to cut good.

I will try explain. The blade set should be so that as you site down the blade, the inside edge of the tooth should be parralell to the inside of the one directly in front of it. Hope that makes sense. Blades loose their set as a result of "hammering" which results from the teeth being offset.

The more set the faster it will cut and have less drag. More drag can result in heat and heat can cause the set to dissaper.

The kerf should be double the thickness of the blade.

Even though it's been a long time since I used a handsaw,I remember that the set is a function of the number of teeth per inch and the use of the saw. On a buzz saw,of course the more set,the more ease of cut and better speed[less heat,as said]. A fine toothed saw would have less set,as a smoother cut is needed.

A good way to set the teeth, on a 30" saw blade, is to remove the blade from the arbor and to use an old railroad piece of track. Place the tooth of the saw outward from the center of the rail and use a ballpeen hammer, to hit the end of the tooth. Then do the other side. Hopefully all teeth will then be set uniformly.

Not a good way. Better way is to use tool designed for it. I think you can have too much set, more is needed for pine than hardwoods.

Mr. T. Minnesota,Here is a good 2 part video on youtube that might help you out.

As long as we are on the subject of buzzsaws, does anyone know the ideal RPM for a 30" blade? I replaced the bearings on the gearbox and may have switched the gears, a 16 tooth and a 24 tooth. So I now have a .66 ratio, and maybe I should have a 1.5. Haven't had a chance to try it yet, (bitter cold). Burning a good bit of wood these days!

Den,
Thanks for the youtube info. Thought I knew all there was to know about sharpening! Will modify my sharpening procedure from now on.

I Tried the saw, I did reverse the gears, as it definitely runs slower, however, that did not seem to make much difference. It still cut great. Still curious about the ideal RPM, max RPM or circumference speed, if anyone knows.

Now that that is resolved and I'm not detracting from the thread, this is part of the fence in front of my place.

Pic is interesting, as the C series Ford is a dead ringer for my '53 C750, color and all. I would guess yours is a 600 judging by the wheels. I guess I hijacked this thread big time.
