So...about that bandsaw?

by Timberwolf

a couple weeks ago I posted a video of an old craftsman commercial bandsaw (benchtop size) that I resurrected and finally got running again. Here's the video:

Doc mentioned I needed more weight on the head because it was cutting slow. I figured I didn't have the gas shock opened up enough.

We were both wrong.

Ok, try not to laugh...

Today, I installed my more aggressive band. Thinking that would also help make a difference. Swapped it in, laid a piece of 2x5 x .120 rectangle MS tubing in the clamps and fired it up. Again, it just creeped.

for some reason I got thinking "I wonder if there's a way to install the band so the teeth are going the wrong way. I couldn't think of any way possible, but still I looked at the blade as I shut it off.

I'll be damned... it's dragging the teeth across.

So...I swapped polarity at the motor, and set it back in motion. Holy hell does it cut now! LOL

I can't figure out why the blade would have been turning the wrong direction though... Everything was wired already when I got it. Are there blades that have teeth going the other direction?
