Re: How to make Lead Screws work

In 2013 we machined the end of a lead screw into a 1/2in hex and mounted it in a typical FRC hex bearing and drove it with a VexPro gear with a 1/2in hex. Everything was sandwiched together with a 10-32 cap screw in a hole tapped into the lead screw. It was drive by 2 CIM motors and a 775+cim-u-lator with a single gear reduction, around 16:72. 72t gear being mounted on the lead screw.

It worked well, we had no issues all season with it.
