Building a R.O.R. a.t.m. and put the first of the rollers together today. That went well enough but has introduced a potential issue.
The roof itself will weigh in at about 250kg when done and I don't fancy trying to stop it if it builds up any velocity.... and really don't want to chase it down the side of the mountain where I am building.
It'll be automated at some point but does anyone have a basic breaking system design that I can use to start with. Don't really want to look at hanging weights, (for the obvious reason), if I can avoid it....
