Trying to determine the RPMs on my drillpress, but it was hard to hold the speed indicator, measure time and do the filming at the same time 😊.
I measured that the motor made 1500 RPMs, but it was so difficult to do this only one person so I think I'll count out the RPMs on the different belt wheels, in the calculator.
In this clip, sorry for the poor lighting, do I hold the indicator to the geared down main shaft.
I didn't have the nozzles for the Starret speed indicator, but found erasers which are supposed to fit on the back of a pencil, and they fitted perfectly on the rotating rod. It's hard to see but I reinforced the eraser with a short piece of copper pipe.
