Turns out I was massively over complicating it. Couple of clamps I had and it all lines up nicely. It will power up and down. Sometimes it binds and won’t come down on its own so I might cable tie it on. I’m also getting a slight twist on the table on power up but over all works really well and much better than manually fighting with it.
Need to work out how to create a control panel. I think I’ll replace the on off with a nvr and look to add my up and down control there. Maybe a plastic enclosure and then try and work out how to bolt that on the side while having it quite far forward.
