4040 VSlot Linear Actuator
Description
This is a fairly easy to build linear actuator (electric cylinder) made using Openbuilds' 4040 VSlot and an Igus 1/4" High Helix Lead Screw with a 1" lead. The square flange nut fits nicely in the Vslot to prevent the nut turning. The nut fits into an 18mm OD / 12mm ID aluminum tube which is a near perfect fit for to use the 4040 vslot as both a body and linear bearing. Video of build - the end has it running: https://youtu.be/fm0g7oYxJB0 The slip mount isn't really meant for extended use. I use it as a friction mount for Nema23 motors, no screws. There are holes that can be drilled and out if desired.
