Nice, and then I'll come along and copy your design again
Sounds like it'll be a mighty improvement anyway. I don't run my actuator at the same voltage as you do but there's just no power in it regardless, so I reckon motor/threaded rod is the way to go. I'm thinking Speed 900 , gear reduction, then threaded rod as I don't want too much force in it, otherwise the chassis will start to fail and I can be bothered to rebuild that.

Pinsor with ti claws and a 1.5ton mechanism should be awesome. Is that planned mechanism the same type of setup as what powers the lifter Tom made for the MW?
