Atlas 7" shaper information.

[Duble]

I have just recently acquired an Atlas 7" shaper which through the years has seen some of its parts obviously replaced with others that may or may not be the original parts. In particular I am wondering about the diameter size of the motor pulley and the diameter size of the pulley (S7=124) which the motor drives on the countershaft assembly. If someone can give me these pulley diameters I would be most appreciative. I have found out the pully diameters of the four step pulley on the countershaft assembly as well as the pulley which it drives in literature on the Atlas 7" shapers.

The motor pulley is 1.156" and the driven pulley is 5.3". The larger pulley may be a little bigger by about .050" since the jaws on my calipers were not long enough to reach all the way to the peak of the circle.
