One side of M8 long nut is drilled to remove threads, other half of nut remains threaded, both side tapped for M4 from the side. https://www.youtube.com/watch?v=qFoA5BDAtZo Use belt grinder to sand solid round for sliding tubes(linear guides). https://www.youtube.com/watch?v=2o4am101QRI lathe build https://www.youtube.com/watch?v=LgxH37q7ty4 I go into some detail on how I built these actuators which I am using to make a variable height table and bed in my campervan. We're driving from Alaska to Argentina, only using renewable energy in our 100% Electric, Solar Powered Camper Van. https://www.youtube.com/watch?v=oKZgyr22VyY old jack

Fits milled brass fitting over end of outer pipe, allowing tight fit for inner sliding pipe. https://www.youtube.com/watch?v=vxhBMiyy3y0 https://www.youtube.com/watch?v=NLscbeoIjAY 3d printed https://www.youtube.com/watch?v=LgxH37q7ty4 https://www.youtube.com/watch?v=7STYIIKDPtY This is how to make an easy Linear Actuator using a 12v dc motor, a Nut and a Bolt, this is made with metal plates BUT! You can use wood, plastic and glue instead of metal and welding. This is meant to be a wire puller with a total of 3.5cm stroke, i hope you can get an idea through this video on how to set up yours.
