I finally bought a new 10" saw blade. Are there any tips on removing an old blade? How do people keep the blade from turning when you try to loosen the nut?

If you can not remember which way the nut unscrews, mark the direction on the saw for next time. Usually there will be a place you can hold the shaft with a small pipe wrench whilst turning the nut. Before installing the new blade, grease the threads so they will not bind up. Also, clean the shaft, nut, and especially the collars before installation. Woody

The nut turns off the direction the blade turns. Looking from the front, if the nut is on the left, it turns clockwise for off. If on the right, it turns counterclockwise for off. Ken

What Ken and Woody said. Also when you tighten the new one it only has to be tight enough to not slip. Over tightening can dish the blade.

All good sense tips. I keep the shaft from turning while removing the nut by gripping the belt and pulley in one hand, while loosening the nut with the other. The rubber belt gives you enough grip when squeezed against the pulley to prevent turning. Also, if any threads show beyond the nut, clean them real good before removing the nut.

Great tips! Thanks! I wanted to have a plan in mind before messing around on the inside of the oily saw.

While you have the saw opened up, and the blade off, you might as well clean it up real good. Save having to do it later.

Good tip on unplugging the saw....I always do that ever since one time I thought the saw's auto-feed had shutoff at the end of a cut when actually the rock had loosened and jammed the blade. I saw that the rock looked funny so I reached in and pulled back the vise which immediately started the blade again. I got a good mineral oil bath and a good lesson at the same time.

My pulleys don`t have covers , on the outside of the saw , very dangerous . I`ve had two people want to see the rock while it was cutting ,pull the lid up and get soak with oil , head to groin .

on my 12" saw, I'm able to grab the shaft (wearing rubber gloves for grip) and break the grip on the bolt with a sharp jerk of the wrench...mine is counter-threaded like most saws....

I finally got around to changing the blade. I used tandl's method of holding the blade in one hand and turning the nut with a crescent wrench. It wasn't too bad.
I didn't realize the huge difference a new blade could make on the smoothness of the cuts. Actually I probably just didn't know how bad my old blade was. It's the blade that came with the used saw.
Are there any good uses for a worn out 10 inch blade or do I just clean off the oil and throw it in the recycling bin?

I watched Randy change a saw blade on our last visit, and learned how he spins the blade slowly by hand after mounting it to check straightness. If there is a bend at all, he hand straightens it right there. He said that if it is seriously out of wack, he takes it back off and uses some straightening doo-dad that he has in his shop for working on cars.
