My astronomy project:
Page II.3: Building the hatch
Last time I was so in hurry to cover the building that I didn't had time to take photos.
Here how it looks when I left it last time. Today I continue to build on the hatch.
First I need some locking mechanism to the roof and hatch, later I maybe ad a motor to open hatch and roof. This eccentric lock is adjustable, it looks maybe a little bit weak, but this is just for the small south part of the roof. The plywood behind the lock is just a temporary solution.
The hatch much have a hinge, you can see it here, just left to the red panel.
I need to lower the hinge and the stud it's attached to. Also cut openings in the panel for the hinges.
Here is the upper stud that has to be lowered to get a lower free view out.
First hinge attached.
Just two hinges will not be enough, I will ad a third one in the middle, and that one will be mirrored to lock the hatch to not move in sideways.
First opening of the hatch!
Now I have attached the hatch to the south part of the roof. I also added another red panel.
Now it's time to separate the roof in two parts. Will the roof hold together or fall apart?
The cut operation was a success!
Here I have planted tiny small green plants. The idea is that those small plants will grow to two meters height to the next summer. The purpose is to have a wind protection and also make the observatory invisible. I have also cleaned the rock from all other green stuff.
To the main roof I use a bigger version of the eccentric lock.
The backside lock.
Here where the letter "A" is I will place a counter balance weight and a chain to lock the hatch in open position.
Added white corners to get it look like an old Swedish house.
This was the last work on the observatory 2016.
I have not found a roof yet to the observatory and now the winter are coming.
