...with the bottom hinge in place the top one had to be positioned too.
This one was marked and cut out to be glued in with 5 min epoxy mixed with Aerosil and micro balloons. This way it hardens much better out to solid and stays that way for even. Also one can grind it easy after a few more min.
Note that the moving part was also covered with 0.4 mm ply strips and cap strips.

So far so good, now we will see what happens next, with holidays to come...

Hi guys,

little progress due to family things...
Anyway the work on the fuselage went a bit forward.
The front bottom part is solved. The doors need hinges now but these are not the top priority.
The turtle back is build on and now the elevator must be lined out and set under the right angle.
Note that the turtle back has a bend in the top line, other than the RF4 back and as the original Milan.
Most of the Milan fuselages are redone this way due to more head clearance.
This means that also a now canopy had to be fitted.
The canopy is the next step on the model.

More soon,

Noël

Hi,
All holidays over, family matters almost sorted...a bit more was fit.
With the formers for the turtle back set up, the elevator was to be installed first.
I did cut two ribs with the right angle of attack of the elevator on, and glued them into place.
After that the cutout was made to allow the tongue to fit into the end former.
Later a piece of ply was cut to support the tongue from the bottom.
A M4 bolt is used to hold it into place.
Now the holding pins can be put in too...

...work goes on now...
the tail part has been reinforce a bit to install later on the two hooks for the elevator.
The plug for the canopy is also shape and glass fiber reinforced.
Two layers of 20 mm foam are added underneath to allow the Vivak to shape all of the piece we want on the canopy frame.
There is always a rounded edge at the bottom...depending on shape, height and temperature.
The top coat finish must be put on now.

Hi Chris and Peter,
I am very sorry that I will not make it to MW this weekend and even October is not sure either.
Family matters took me too long, and kept me from modeling and even flying...
This is changing now back to more free time.
That you will see in the next few weeks to come finishing the Milan and more...
Noël

Hi,
the canopy mould was sanded down and ready to pull the real canopy for my Milan.
Together with two other canopies the work has been done this afternoon.
Some of you maybe ask how one does this. A friend was there to film the process.
Once the plug is in the machine the Vivak sheet is place onto the frame and secure by a counter frame. Vivak is the plastic sheet that I use. Works also with Pet but the temperature, if too hot, make the sheet milky, so not clear any more...How do I know...
Both sides have some sharp pins to hold the Vivak in place.
Also sealing rubbers are all around to be able to do the vacuum pulling.
I look down to check on the Vivak sheet for the hanging down, telling and showing me if the sheet is ready to go. I learned how much this has to be...
From that moment on all goes fast and a little waiting has to be done to let all cool down a bit before letting go of the table.
See the result...

...also the cowl for the Milan is almost ready to be made in a top and bottom half moulds.
A last time grinding will do the job before waxing all.
This is for later this week.
