I'm not sure I'm in the right section, but I will ask the question anyway, please move it to the right section if need be. I am building a go kart out of left over pieces I have lying around. I am having a senior moment and want to be sure I have the pulleys going in the right direction before I weld in the brackets. Right now I just am mocking it up (that explains the broom handle for a shaft). I have enclosed a picture. Thanks for the help.
