This may not be the right place for this question but here goes. I've got a hand winch and cable and I'm planning on using it to make a hoist. I'm going to mount the winch to one of the supports in the shop and route the cable to a ceiling beam/rafter. I need 2 pulleys but I'm having a problem finding the right kind of pulley to mount directly to these posts. Any pics or advice would greatly be appreciated. Thanks
