I'm doing a few test runs on this new K40 i got,

Fyi - Standard belt tension on pulley devices is 1/64" × the length from pulley centers.

@Abe_Fouhy what is that measurement of?

Standard belt tension for machines using pulleys, this value is how much deflection of the belt you should have if you put your finger on the belt and push down on the belt in the middle of the distance between pulleys

@Abe_Fouhy thanks that what I figured.

@donkjr You bet, just glad to help in some small way here after all the awesome help
