We use this Spindle Force Test Gauge Cat40 And Bt40 | eBay

and it works well. What drives me crazy is that when our tech came in to replace the bellville washers one of our Fadal 6030's read 1600 lbs and the other 1200??? He had no good answer why they were different. Maybe I got the wrong tech and need to do it myself. WE are in Gainesville, GA and it seems that all the techs are not up to snuff on these machines.
