Hi Max,
I did use on off a PT edger but it gave me a lot of grief because it was so big in diameter to start with. I had to cut it down with the oxy and then put it in my lathe because my lathe is Myford 7 and it is slow going. I guess I will get some 80mm discs laser cut and then turn them up from the blanks. Getting to be a real problem when I pick these slashers up with no motors on them or somebody has dummied up some sort of pulley.
