Hi,

 

Before continuing the other molds, it was necessary to be sure that the fuselage was castable.

because the thickness and many detail as main frame, frame, stiffener, the fuselage will be very difficult to cast.

Without the fuselage, it is useless to make the rest of parts.

 

MostlytRacer vacform the shells(1,5mm plasticard) on the master

drawing the frames, stiffeners are already in place. (I use plastic strip for frames and stiffeners, and plasticard for main frame)

and the first test.....theere is some bubbles, the ambiant temperature is too warm (near 30°), the resin harden too fast, bubbles are trapped. The fastcast is Veryfastcast

Another fuselage casting, made the night when the temperature is lower. it's better.

For the next, I try cast it in the refrigerator.....

Already, the last week my wife find the mold in the oven....

Hi,

 

I've just been following this epic thread.  I have  a question:   From above pictures, how did you go from vacuform to resin? Do you have any step-by-step pics? I am just curious how the vacuform master was turned into resin. What techniques did you use? A two-part mold? Slush-casting?

 

Thank you in advance.

@ jack: I make à counter mold before cast the half fuselage.

 

Oh, so it's a 2-part mold.  Do you cast in a pressure pot? Because the details look fantastic!

 

Thanks in advance.

Today, I make the molds of the wings. nothing spectacular. The wings are put in boxes with the clay which delimit the joint plane. silicone rubber is poured, now I must wait 48h before removing the clay to make the other halves molds.
