Designed this for a friend who's kids National Geographic rock tumbler broke... The press fit is very tight (I used a clamp to install it) but i also added a set screw. He's had it running for a week now since installing the new pulley without issue.
Uses m3 nut (http://amzn.to/2kRawZN) and grub screw (http://amzn.to/2kR2CiX)
