I don't know why the Belt Sander speeds are so different in new vs old speed charts.
There are two things that hit me immediately.
First, the old speed chart does not specify grit size so we do not know what Course, Medium and Fine actually refers to. That is not too important now given the second thing.
The second more glaring difference is that with the old chart the larger the grit the slower the speed. On the new chart the larger the grit the higher the speed. Both can not be right.
Since everyone has been using the old chart and speed dial for 60+ years my guess is that the new chart is wrong and if so then the Power Pro headstock is wrong. If this is true how does SS correct the computer in the PP head stocks already in the field?
Can someone with close ties to SS check with them on this discrepancy?
