Again, where did you get that @wachuko ? I did a search of this thread with your name as the qualifier and I got 400 pages...

Now, I need to fix the bungled-up mess under the vise. The idiot apparently wore the ACME shaft down, and instead of fixing it correctly, he just turned the shaft around and literally cobbled up a nut, some bent-up metal for a spacer and zip tie. This guy said he was a tool and die maker but retired because he didn't get along with some of the guys. No wonder.
Thank you!@7milesup
Nice job on the general refurbishment and especially he new fan.
I'm wondering "what manner or form" the wheel was worn? In other words, was it conical, eccentric, grooved, what?
I thought that those wheels should have a crown (not cylindrical). What is your thought.
Also, does the wheel take a tire or does the blade ride directly on the wheel?
conical meaning it is crowned? Crowning is used so the blade rides on top of the crown. Bands always seem to ride to the highest part of the wheel. So it keeps it centered.. also it prevents the teeth from riding on the wheel too.Thank you!
According to the instruction manual and parts diagram that came with the saw, this wheel does not take a tire, although it is my understanding that some do.
The wheel appeared to have a conical shape where the blade runs. In other words, if you took too fast of a cut and ended up straining the blade, it would pop off of that wheel. There is a lip on that wheel that you can see in the picture, and there is a small groove right next to it, which allows for room for the swarf; otherwise, it would accumulate and possibly force the blade off. It was hard to check the angle of this wear. I ended up just touching my carbide insert cutter to the wheel next to that lip. Then, I moved the cutter toward the tailstock and determined that the face of the surface that the blade rides on was worn at an angle towards the centerline of the lathe. I forgot to take a picture of that operation. The picture that I posted shows my attempt to make that groove slightly deeper to allow for the metal I removed.
I hope that makes some sense.
Ok, then I am using the term incorrectly. Not conical. Sloped? Angled?conical meaning it is crowned? Crowning is used so the blade rides on top of the crown. Bands always seem to ride to the highest part of the wheel. So it keeps it centered.. also it prevents the teeth from riding on the wheel too.
Flat wheels don't track well generally. There are exceptions I'm sure.. but crowns are good.. flat bad..

I think I need to draw a picture. Hang on while I hobble to my office (knee surgery yesterday).
