Grinder RPM & Grinding belt tension

I was just wondering,not that it matters,.What RPM,or I guess it is FPM,does my grinding belt run at each step on my 3 step pully with a 1725 RPM 1 1/2 HP motor? Also

How tight do you guys run your sanding belt on a NWG? That may not be very important but I was just wondering.
Thanks for any help.

God bless,Keith
 
On my KMG and my EERF grinders, I run the tension TIGHT. A tight belt tracks better and creates a truer flat. Just take the belt off in between uses or you *might* see some stretch occur.

As for FPM, what diameter is your grinder belt drive wheel? And what are the diameters of your steps on your step pulleys?

Thanks Nathan,I also see it tracks better to run it tight.The step pullys are 2'' 3'' & 4'' the drive pully, come from Tracy,and I think it is 4''.

Thanks Wayne,I have not looked at that,but I will check it out.

Thanks again guys,

God bless,Keith
