I started on this sometime in July . It's a work in progress and I have an issue with the roof trying to walk around. I need to fine tune the position of the wheels I guess. I designed it so I can drop the roof back down to hopefully keep the bugs out etc.

lots of pics here

Thanks, it works ...just turns a little hard which I hope to improve by fine tuning the roller positions. I wish I had used golf balls now, I think that may have worked better

Got a chance to align the caster axles with the center of the building, made a HUGE difference. I can now push it pretty easily most of the time and sometimes when i give it a shove it keeps on going! I used a laser set up in the center of the ring and an old secondary mirror to bounce the beam back.. I just kept adjusting the roller carriers until the beam bounced back to itself .

Nice obsy - yes - golfballs will bunch-up and jam UNLESS grouped with each set enclosed in a 'sleeve' on underside of dome to keep them apart :grin:

Thanks , didn't know that about the golf balls. I think i'm getting there with the rollers. It still tries to "walk" but my side rollers are helping with that . I may replace my homemade side rollers with actual ball bearings

I worked on my sliding hatch today. It uses a couple of old server rails . While I don't quite get 100% clear opening it's pretty close and can't beat the price.

Very slick. That's either a dome that aint, or a gable roof that thinks it is. Either way, it's a great idea. Stealth.

Norm, if you have any problems with the observatory, just contact CN member 'photonovore' (Mardi Clark). She designed and built her own "Roll-Around Roof" Observatory quite a while ago and would probably be more than happy to help. I've known her for a number of years - she's absolutely brilliant, and is definitely what we call 'good people'. :) Not sure how often she checks in here though, so you might have better luck with email. The address is at the bottom of the web page (just above the 'Construction details' link).

Once I clicked on the link...Very interesting.... I contacted her before I started construction as I liked her idea. I couldn't build it as light weight as hers because of the snow
loads we get some years but it still is the same general idea.

I guess it's been a while since I posted any pictures. I finally got around to painting the inside, got my rope lights installed and roof controller working with or without a PC. I can see I need to tidy up my wires for sure :)

Norm,
Do you have other photos of your impressive-looking observatory?
