Teeth vs finish

[Mike1950]

In the beginning I associated more teeth with finer finish, just an assumption but it is seldom right with band saw blades .
1.25 wide. I think 1 tooth per 1.3" carbide. Probably 2 years on saw. Starting to dull a little. I use for hard clean stuff. Blade guard is set at 14" and block is 13"+-. Saw table is 21 wide for proportion.
I am always amazed how wrong that assumption was.
Hard, marked afzealia , maybe. Seems a mile colorful. Pretty smooth for that tooth.

Think @Mike Hill just might want this chunk of wood...

Wow that is some beautiful wood.

Feed and speed?

Feed and speed?

depends- when 13 inches of blade is in coco or you are cutting thin stuff. 13" by feel but it actually cuts it pretty fast. when you get thinner, I try to keep it at under the self feed tendency of big toothed blades. if you feed it too fast the tooth wants to pull wood into blade- lots of chatter and even after happening many times still wakes me up. It can really get bad on carbon steel 2 or 3 tooth. This blades does not seem to pull when fed too fast, but it does get chatter which makes cut rougher. If you feel and listen every blade style has it's own sweet spot. This one loves to eat hard stuff.

I dont have much experience with carbide blades, but for carbon steel blades I think the rule applies; higher tpi, smoother cut, must be some magic at work in the carbide blades

With a higher tooth count, you need to go much slower or have a more powerful motor. ................ Nubs

You try to cut 13" coco with a high tooth count blade and it will be an exercise in frustration. You need big gullets to have storge to collect waste and not fill gullet before it can get rid of waste. Otherwise resaw blades would have lots of teeth. If gullets get full before bottom of cut, the blade cannot cut. end result- rough crooked cut.... a highland woodslicer (dedicated resaw blade) leaves a very fine finish with 3 tpi- just do not use on green wood.
I hate my laguna resaw king but it has large teeth, has to.
