The aim is that this project is also the project of my chidren
becasue I want them to fill in the feeder tank :-)

So they did the draws of the birdhouse
and I took some ideas from their draws

Here it is a birdhouse for several birds
and with several floors

And here is my first compilation of their draws

Here is my organization of layers
regarding layers for CNC's jobs: 1 for pockets, 1 for inside cuts, 1 for outside cuts

Here are my Joint models and the Mill bit
very useful to have it for copy/past

Here is the detail of my circular arcs
6.05 mm (not 6.00) to be sure the mill bit can go inside, and to be sure Vcurve will manage it correctly

A lot of joints and a lot of pieces ...

Here is the settings of the Autocad Export Scheme
Rhino objects should be exported as polylines, max angle set to 0.5 and "Explode polycurves" should be disabled

Here is the wood we are using
plywood, board is 1200x2500, 12mm thickness

Equiped and ready to start ... ;-)

Starting with pockets

Then cutting

Now CNC job is finished, my job is starting: sanding

Sanding is finished, now we will know about the result, will the joints work or not ...

First test is ok :-)

Main structure assembly is working

The doors of the nests are working fine, this is great, it was not so obvious to design

Now redoing it with internal pieces also, still going fine

Here is my Big Object finished! all joints are Ok

I used nearly all the size of the board

And the place is cleaned for the next worker
