Ok well I went shopping again yesterday.. my Dad was down from Bellingen for the day too, so used his handyman skills to help me
Bought the K-3070 controller and a kit box from D.ick Smith, and some aluminium "stucco pattern" sheet from Bunnings (they didn't have plain). Oh, Matt didn't tell me the K-3070 was a "put it together yourself" kit - I was hoping it would all come pre-built!
So I had to buy a soldering iron and some solder too.. this will be fun, haven't done any soldering since 1988!
Anyway, made the mounting plate for the fan.. cut a 285mm circle out of the alumium, a 90mm hole in the centre for the fan, and 6 holes to go over the collimation and lock screws. All done, all looks and fits great.
The fan is in place, but I haven't had a chance to build the controller kit so the fan isn't powered yet. I also haven't taken the mirror out yet to clean it and fit the outdoor temperature sensor - i'll do that tomorrow if I get time.
It feels great that this is finally all coming together.
