Check those band saw blades!

When you uncoil your blade, you can end up with the teeth flipped.

NO, the teeth always go the same direction! That said if put on right will cut fine. OR VISE A VERSA

You missed the point of my post, you can take a welded blade, that has been "folded" into 3 coils, when uncoiling these, you can end up with the blade reversed so that the teeth are backwards when installed in the bandsaw.

You have to take into account the fact that a blade can only be mounted on the saw in one orientation, i.e., with the teeth on the outer side of the drive wheel.

Try this gedankenexperiment...

Blade on (assumed vertical) bandsaw - teeth pointing down (will cut on downstroke)

Flip blade as shown on video, teeth still point down but I have to rotate blade 180 degrees about vertical axis to remount on bandsaw (toothed side of blade must be on outside of drive wheel).

Teeth now point up and will not cut.

Draw some teeth on a strip of paper and try it using a coin or bottle cap to simulate the bandsaw drive wheel.

I'm lost. If the teeth are pointing 'out'...you just orient the blade so the teeth are pointing down when you install it...?
