EDITED: I put up single pics on each post. Not sure why they don't allow multiple photos in one posting.


This picture is using my radius drawing jig to make the template in the 1/8" Masonite board.

There are two ways to include pics. One is to simply add the picture to the post using the button that's available when posting. However, that limits you to one picture per post.

To include multiple pictures per post, you can use any of the standard image hosting services like Photobucket, Shutterfly, etc. and include properly formatted links to those images.

If you already have photos somewhere online, the easiest way to post multiples within a post is to use the "image" link in the preview reply window and add them there.

But it's not hard to post one at a time from your hard drive, either.

Cutting out the rough ribs. Used the jig saw to rough cut, then a router will trim them up to the final shape.

My $1.49 router table. Used a wooden box cover that was covering an old Briggs & Stratton engine outside. Turn on its side it became my router table. $1.49 was for longer base screws.

Ribs for the base ring are finished being trimmed. Next, I have make spacers and layout the base ring and trim the pie pieces to make a circle.

Very nice! Any information about the dome you're building? Diameter? Type (framed/frameless)? Etc...?

It is a 7.5' diameter wood dome made with curved plywood ribs. Will be making an 8x8 base for it.

Here is the website of the original builder:

http://www.baetsenob...ts/ObsDome.html

The plans in PDF format are in that website.

Just fitting the base ring pieces to be the 91" diameter. Mine is a little larger but I need to trim the ends anyway. Just figuring the amount to trim.

A lot of cutting; but you certainly managed to get it done, and the ring looks great!

Hi everyone. I have not been working on the observatory build as of late but I am starting again.

We had a huge dump of snow and I spent hours on the tractor snow blowing it. The wife got stuck on the rural roads the next day so she ended up staying home that day after I towed her out with the truck. The snow was drifted up so high and thick. They took 3 days to plow our roads because of the amount and slow progress. So that was a bit of distraction to building.

No photos today but I did sand the inside of the base ring so that the roller wheels will roll nice. Tonight I am going to cut and glue the second base ring. After that I should have more photos to share.

Keep checking back as this project is not stalled.

Cutting out the rough ribs. Used the jig saw to rough cut, then a router will trim them up to the final shape.

Interesting - your base ring and ribs from the same cut. Just for others considering such a project I find structurally the ribs [in vertical position] can be about half your size relative to the base ring, and whilst neat, it isn't essential to make the second cut to the inside edge within the dome. This saves by halving the total number of cuts. Hope you didn't mind the suggestion here :grin:

I agree with the above. Doing the extra cut does make them look nicer, but it's faster to just trim the top to size. That's what I ended up doing on my dome. Here you can see the rib on the left with the 2 cuts, and the ribs on the right each with a single cut. The inside cut of one rib forms the outside cut of the next.
