Many thanks for your nice supportive comments, Rick, Stephen and Giuseppe! They are highly appreciated.
Last weekend I finaly found some time for the workbench again, so I started working on the propeller. The centre section will require some more filing, but the shape seems to be quite ok.
I had to spend some time experimenting with how to create the undercarriage. I only had evergreen profiles, so I needed to find a way to give them the right shape.
I used red marker and painted both sides, afterwards I took a sharp scalpel blade and started scratching off the edges. Thanks to the red marker I was able to keep good overview about the amount of material removed.
The rest was easy, I used my drawing as a template:
On which I afterwards glued the profiles cut to the required shape with CA:
And glued them together with Tamiya extra thin to weld the joints.
In the next step I will remove the CA with debonder which will loosen the parts from the paper. This is pretty much the same method I used for the interior construction.
Cheers
