    The photo of the speed chart is especially useful. Thank you for linking that.

    but to really sure you need to know the diameters of the pulleys... all eleven belt grooves

    After calling Brobo I discovered the intermediate pulley and the motor pulley are no longer available for the 8SN but that they are available for the 3M. The only difference is that the motor pulley bore is 19mm rather than 5/8" and the intermediate pulley block does not have a groove machined in it to let the motor mount bars of the 8SN slide past it. However early 2M and 3M intermediate pulley blocks do have this feature so the part could fit both the 8SN and 2M/3M. I have moved these parts from my recently acquired 3M to the 8SN thus allowing its completion. In the new year I will order new parts that will work on my 3M from Brobo.
