    Gear / motor for lowering screen

    I've got a ~3m wide heavy fabric screen mounted on a 2" mild steel pipe that sits on pillow block bearings about 2.5m above ground. I've got a sprocket attached to one end via a taper lock bush.

    Double plasterboard reason and mounting screen in garage

    So, I'm planning to hang a big projector screen (3m x 3m) - with pole, screen, fixing, I'd estimate 10-15kg - across my garage (for an indoor golf simulator).
