Thanks, I had some fun with the decorations
I have tested, the pier is mounted on a raised slab which does not come in contact with the floating floor, so as long as I don't jump up and down with excitement then there's no vibration at all. The whole thing is on my in ground water tank though, so if I jump up and down anywhere on the tank then the vibration comes through - however just being 'normal' and moving around does nothing. I can move in and out of the obs and around the tank without a problem.
The roof is just a set of shower screen rollers screwed into the side of the shed roof, which rolls on and off some aluminium t frame that I out on top of the walls as a guide track. Manual on and off but it leaves room for automation some time later on
Got to have room for improvement somewhere
I've got some shots of my equipment actually on the mount now, they're on the twitter page - or will be soon when twitter decides to come back!
