[Steam-engine] Belting question?

[Andre' Blanchard]

I am not completely clear on what you are looking for with the rolled up 
part, but.
If you add the diameters of the two pulleys and divide the result by 2, 
them multiply by Pi (3.1415), then add 2 times the distance between the 
centers of the pulleys you will get the length of the belt needed to go 
around the pulleys.
This is not exact but unless the difference in sizes of the two pulleys is 
extreme and the center to center distance is very short it will be close 
enough for most work.

Or with a little simplifying.
(1.57(D1+D2))+(2C)
