.... Getting sheets to bend on two axis [sic] has proven difficult....


Time to treat yourself to an English wheel? <g>

The English wheel is the traditional tool of choice for forming compound curves in metal, i.e. curves in two directions:

The good news is that it doesn't have a motor and is fairly inexpensive because of its simple construction.
The bad news is that it takes a while to master the technique.

Ah got it! Yes, that could fix it. I have another idea that might avoid the need though. I'll keep you posted.

What an awesome build from your tiny cardboard plan!

This is going to be a one of a kind observatory, truly beautiful!

Let it not be said that I have not spent blood on this observatory! Nearly dropped the door from the top of the dome today, caught it mid-slide but managed to run my forearm down the edge of the sheet-metal. Saved the door, lost some blood.

1. Interesting seeing the muscle under that many layers of skin.

2. Stitching it up, a couple more to go. Good as new and back to work!

Blood sacrifice to the observatory gods. I took most of the tip of a finger off on some roof flashing when the wind caught it. 5 stitches later back to work.

LOL...funny dudes..


No, I didn't have any suture gear so I had to pop into the local hospital and ask for some stitches. I will be buying some so next time I can just stitch up myself and keep on working.

In a pinch you can use monofilament fish line

I couldn't resist :smirk:

Hope it heals soon and be careful next time!!

So I'm not the only who has shed blood over my observatory.

Blood on the observation deck. - 1 Dec 2012

It's been an interesting week of fiddling about. I've been putting up some of the roof sheeting and finding it challenging. Not only because of the difficulty in handling such thin and cumbersome material, but at height making it all the more dangerous and time-consuming.

Full story and photos here >> http://www.asignobse...onstruction.htm

Here's a link to an animation of the doors opening and closing. http://www.asignobse...ors_Opening.gif

1. Roof sheeting going on. Slowly filling in all the sky gaps!

2. About 1/4 of the roofing done.

Every successfully home built project requires that you bleed for it. From installing a new motherboard in your PC to building an observatory. I have many battle scars from astronomy. My hands are so full of them that people think I have been getting into knife fights. My scars are named, Synta, Meade, Losmandy etc...

^^^^ LOL! Creative... I like it.

1. Nearly half-way with the roof sheeting.
Posted Image

2. View through the slot from the far wall at telescope height to give an idea of where the horizon is in relation to a horizontal scope.
Posted Image

3. View through the slot from directly above the pier, where the telescope will be mounted. No need for the slot opening to be any lower as all you will see it trees and oncoming cars from up the road.

It's difficult to tell with the photo's distorted perspective. How far past zenith does the opening go?

1. Telescope installed - fire extinguisher fitted as priority!

2. Preliminary calibrating on the moon.

3. "FIRST LIGHT" through the ASIGN Observatory II telescope! A very quick shot with only the DSLR on the scope, but enough to check the optics.

Congratulations! I've been following your progress for the last few months. It must feel really good to be able to finally use the observatory after all of your hard work. Your build (and others) are inspiring me to build my own permanent mounting solution, although I will probably end up with an "outhouse" type rolling shed (due to lack of space for a "full" observatory).
