Re: To Kerf Adjust Or Not....that Is The Question.....?


Prestige,

I'm having a hard time decoding this thread. Are you asking if different saw blades have different kerfs?
If so, then as you already know the answer is yes.

My blades vary in kerf size (the width the blade removes from the wood) and in the distance between fence and the "inside" of the blade.

Is anyone arguing that fact?

My rip blade removes much more material than my combination blade.
Do you want pictures?

Also, if it's a different blade and the distance between fence and the inside of the blade is different, then the marker on the fence will need to be changed with each blade change.

I think that is what you were talking about. You are not loosing your mind. People are [email protected]&kig with you.

Re: To Kerf Adjust Or Not....that Is The Question.....?


Isn't the 'Kerf' determined by the alternating "Set" of the teeth/tip? Not the width of the tip?

If the motor is on the fence side, aka your saws right hand sides are always in the same place 3/32" is a butt load of "tip" or "Set" offset. Kind of like the tips are not centered on the body of this blade.... Stranger things have happened

This is it, but he can't grasp it for some reason. The scale on the table on that saw is referenced off the blade flange on the motor side ( right of the blade). That combo blade has a different body then the rip blade.

A different width of kerf would only get you a difference in fractions of millimeters.

This big difference he is throwing a fit over, is not kerf it is the body of the blade.

Chances are they are both different and the error is adding. He can't adjust his pointer?

The scale is etched in the table. No way to change that.

He is hung up on the kerf of the blade, which is not the major difference between those two blades.

His rip blade is a wider kerf.

His motor is on the right, correct?
If so, he cannot shim it to be in line with the pointer. He would need a NEGATIVE shim which does not exist.

Maybe a thinner thrush washer?

I know what you're saying.
It all comes down to the distance the blade tip is offset to the blade body. He must understand that!

If it's less than the design you cannot fix it with shims. If it's more than the design you can shim it closer.

I guess that's why my powermatic has an adjustable pointer. Haha!

Re: To Kerf Adjust Or Not....that Is The Question.....?


Huh.

More important, IMHO, is that it's all relative as long as the behavior is consistent. In other words, I can keep my cabinet work within 1/32" on my cheezy Crapsman bench-top saw, simply because I'm familiar with it's nuances, the blade I'm using, and it stays consistent.

If there's one thing we should all accept earlier rather than later in life, is that there are no "absolutes", even if they're etched into a table top.

Re: To Kerf Adjust Or Not....that Is The Question.....?


The rip blade appears to have both a thinner body as well as less side clearance, where side clearance is 1/2 the difference between the plate thickness and tip thickness.

Thats pretty extreme though to see it off by that much. Is it possible that one of the blades is cupping when tightened shifting its ouside rim to the left?? Have seen something like that, but it was with a cheap blade on a cheap saw. If the blade is cupped, a kerf on a board would be wider than that of the tips.

Pretty strange.
