Title: what do you do with overset teeth on you blade
Post by: ozarkgem on March 08, 2015, 09:08:07 PM
while trying to figure out my new setter I over set some teeth. .030. A lot of them in fact. Its sets fast. 1 min for a blade. I tried flattening them with a hammer but that
took  a long time. I don't think I can saw with that much set. Plus its only on one side. any ideas on how to get the teeth  back straight so I can try it again?

.030 is not that much I'm thinking, might try and give them a go for a few, if it does not work, then back off a bit, more set does or should say has caused some rougher finishes, but trial and error is the best recipe in my book, everything is different for on sawing depending on the wood and circumstances.

I run all of my blades at .030. I would say just set the other side the same and run it.

I've had the best luck using pliers.
Don't grab the tip, they are brittle and might break.
Use pliers with a flat face, grab just below the tip
and squeeze lightly. It doesn't take much pressure.
Good luck.

If I over set my teeth, I just use the setter backwards to un-set them.  If you overset them all evenly, you could proberly set your setter to unset them to the correct set.  Now try saying that 5x fast

Set the other side to .030 and run them.  You might like the results.  I commonly run bands between .022 and .030

I'm in the "set the other side and run em" camp. But when I do overset a few teeth I use pliers...just regular old cheap pliers, fast and easy, bend back and reset.

I too use pliers if it's just a few.  But if I find out near the end that my dial indicator was off or something and I overset a bunch of teeth, I use the setter.  Takes longer to set up but is quicker and easier.

Set the other side and run. Especially in softer woods. If sawing pine or Hemlock I set a t 30.

Mine is automatic. I tried that . Its sets both sides in an alternating pattern an it wouldn't work. Guess I could have used my old setter. Just now dawned on me.

I will give the 030 set a try. Sawing ERC

Agree just use them at 30.  However if you're like me you will end up with some 35s too.  Use those for spruce.  :D 

When you have too many spruce blades and even before, like when you have some 45s,  :o :o :o make one of these as PDrouin and others have done.  One pass of a blade through will make all my teeth 19-20.  That's great for frozen but also for uniform setting to whatever.

I added a roller so there are 3 on each side now, since the picture.  Those are old 5/8 cam bolts and bearings from my WM LT40 blade guide arm assembly.

I think it is a good idea, too. As you roll the band through the bearings I assume you have to allow for the teeth to spring back some. So, what roller clearance to you allow for the 19-20 set?


I use this little device which I learned of on the FF. Just slip the slot over the tooth and bend back. OK for a few teeth but a lot and I would use the roller idea.

Didn't measure any clearance . That's what I got first time I set it up, didn't change it .

What kind of setter do you have the WM one?

Its a Moon saw shop setter and sharpener.

Oh ok.  I have no experience with that one, but they look cool from what I can see online.  On my Cook's, what I do is back the bender units all the way out.  Then line it up with one side, so that the bender unit is bending the tooth the other way.  Then I will set it to where it will unset the overset and try to nail the set that I wish to achieve.  Then I un-over-re-set the teeth on that side.  Then I do the same thing on the other side.  Works well for me, and the ladies love it  8)

OK, I'll ask the dumb question, How do teeth get over set ? MY setter has a stop at max set. Adjust that so .29 is max, and set every tooth to max. Don't need the dial indicator, took it off...Works good, quick...wm setter....

Well there's alot of ways.  It's spring steel for one, and you're goal is to push it to the right spot that when it comes back it will stay where you want it.  If you push it too far, you have an over set tooth.

If you forget to adjust the height from a different band that had a taller tooth, it will be pushing from a lower spot, over setting the tooth.

If you set the bender dies out too far, you have an over set tooth.

If your weld joint gives you a bad pattern, you can get an overset tooth.

I'm gonna start calling them a buck tooth, cause it makes sense, cents, and dollars.

Not sure how far mine will set. 030 for sure. It will set tooth spacing from 1/16 of an inch up to 1 inch. Blades up to 2" wide.
