I've been plodding away with my lifter design.See below



Still needs cut to length. I will do this when the lifter motor is fitted along with the lifter arm.



I used a 25mm mild steel tube, with a 20mm inside diameter. A 20mm m12 thread stud (about 25mm long) welded to the tube. And at the oposite end I've welded a similar threaded stud for m12.
