Thanks Ed.
In my previous post I had just finished the first of eight roof frames.
I'm happy to say that now seven are completed and I've started on the last one. 

Hi all,

first test fit of the roof frame for the roundhouse.
Mark of and cut to length.
First pic.
Completed frame placed is place to check. Needs some fine tuning, but I'm happy with the result.
Now to make seven more. 

Then I made myself a jig again to assemble the roof frames.
Third photo shows the partially finished first frame.

Aloha,

small update. I had started making the front wall of the roundhouse, first the outer wall
which I then scored at the back to bend it to the right angles.
When I want to make the inner wall I discovered that I should have done this first and then
the outer one.
Inner one was now to short. 
Then I had a idea, why not cut the inner wall into separate sections for every door and make up
the short fall inside with wood strips that I need anyway for the roof frame.
Cut some wood one the circular saw and tried my idea.
 
On the third photo you can see the wood strips.

 

Nice!
