The most significant values to be concerned with are:
Top Center force (left and right are identical, this is the location where the static forces are the highest)
Bottom Right Left (this is the location where the static forces are the lowest)
extreme chain angles are left chain at top right and right chain at bottom right
Note: This does not take into account the chain sprockets and over/under feeding.
If you are bottom feeding, subtact sprocket diameter from motorHt (~1" for the stock maslow)
