Hey Bill, I would be interesed in a pic of the chair you built ?
Man, the best thing I ever did was cutting up that pram ($10 at a garage sale!). I actually did hurt my back luggin the thing in and out. Maybe I should just build an observatory.
The Fan I use in the winter for reaching equilibrium of the mirror, and in the summer for colling it down. It runs on a 12 volt batt (90cm square) in the dob base. I intent to run some steppers from this batt as well for navigation ? (maybe at a later stage).
