Is variable pitch and variable positive claw the same thing?
It seems like it Timberwolf blades describes one of their blades
"TPI (Tooth Per Inch): 2/3
Tooth Design: VPC (variable positive claw)"
The 2/3 tpi part makes me think it's the same thing different term.

I may have discovered another clue. If I pinch the blade between my left thumb and forefinger and then pull the blade through with my right hand, I can feel irregularities.
A thorough visual inspection of those irregular spots indicate a slight shiney spot. Visual inspection along with feeling that location, I detect a very slight bend. I suppose it is possible that the rough cut is created by this "high spot".
I have a new blade ordered. When it arrives, we'll know for sure.

Twisted at the bend(s?).

Is that a prognosis or a question?JPG40504 wrote:Twisted at the bend(s?).
The blade does not seem/feel as though it is twisted. Just a slight kink. I don't even know if this is indicative of a problem. It is just an irregularity to touch/feel.

A positive answer to the question would validate the prognosis.

No, I don't think it is twisted. Just a very small kink.JPG40504 wrote:Twisted at the bend(s?).
A kink that I may have caused. When I am working on the band saw and have a blade removed, I often stretch it over my jointer (end to end). I likely won't do that anymore.

coiling bandsaw blades
Dusty: I used to fight to coil bandsaw blades into a circle. Then, one day on the http://www.woodmizer.com site they showed a different way to do it.dusty wrote:No, I don't think it is twisted. Just a very small kink.

Put your gloves on and grab blade on each side teeth down. walk up to work bench or anything below your waist. keep walking one part of blade is hooked under bench the other end is pushing against your belly. All of a sudden the blade is in a nice coil.............slickest deal i have seen for blades.....

That looks like a 1/2 or 5/8, 3 tpi resaw b.
Do you have a 1/4, variable you could try?
It is said that a large resaw with few teeth sets up "harmonics" (might be my word, don't remember if that was the one used) especially in thicker stock. The variable-tooth blade is meant to eliminate that (also helps a bit cleaning the kerf).
If you want a really want a clean cut- one you have to hold up to the light to see any saw marks- try a 1/4, variable Hi-Count (16?- forgot what is available), slightly over tensioned (No more than one mark) with a very slow feed rate. The slow rate is more than compensated for by the no sanding cut.
Do Noy Force the feed.

Good news-- the bearing is good.
Bad news-- its adjustment isn't.
