By DIY Jet Engine Guy

Note: this is a lathe intensive project

A heavy duty pulley for rope,cable or chain. with variable lane width it can be scaled for use with different diameters or multiple ropes. The pulley is made of a cast aluminum block which will be shown in a future Instructable and video.

Tools

- A lathe (you could also 3D print the pulley or carve it from wood)

- Angle grinder or hacksaw for cutting the bracket

- Power drill or drill press for drilling axle holes

Materials

Pulley

- A block of aluminum /wood (hardwoods oak/maple) / plastic (HDPE/LDPE) approximately 90mm diameter and 100mm wide aluminum is recommended
