Pilatus PC 21, 1/32 Scale Scratch Build, Part 15

Sitting here in the DRC at the moment, missing Family and the work bench, I was going through my build pictures for the PC 21 and realised I did not post the vacuum forming of the cockpit. well here is a brief description :
Started with cutting out all the ribs for the cockpit, this was made easy as they are on the drawing, I then glued them onto a piece of plastic card that was cut to the same size as the cockpit opening. ( I constructed this in the same manner as when I made the molds for the fuselage halves).
I then added the balsa wood and sanded to get the shape using the rib sections as a guide.
When I had finished the sanding, I vac formed the cockpit in white plastic card, 0.3mm thick. I then sanded any defects out of the canopy, glued plastic strip on the white canopy, and used a very fine sandpaper to remove any small scratches.
I then placed the white canopy back on the mold, removed any dust and vacuum formed the clear plastic canopy. I used a PET-G clear plastic, 0.5mm thick, I also used a heat gun to keep the plastic heated while vacuum forming to make sure that the plastic folded around the mold properly, and that the framing I glued on earlier would show on the finished canopy. The heat gun really worked well. I was really happy with the final canopy. I usually have to make 2-3 canopy’s before I am satisfied. This one worked out first time.
As you will see on the final pictures, I have started with the internal framing of the canopy, this will be painted black and then glued into the inside if the canopy.
Its not the final build pictures as promised, but I thought you might find it a little interesting.

The pictures show the cockpit in position, as you will see it needs to be shaped and sanded to get the proper fit. The cockpit framing, when glued in will help to get the proper fit.
Nearly there, just need to get home and do the final finishing then I will post the completed model.

Cheers from the DRC.

  1. Amazing work Marc, a real beauty you made there! Congratulations and you have my vote for best model of the month!

  2. It looks AWESOME Marc. A WINNER for NATS 2019.

  3. Marc – Looks up to the standard we’ve all come to expect from your projects. I particularly like the tip about perfecting the canopy shape by making a white plastic “undercoat” that allowed you to perfect the clear plastic. The heat gun’s also a great tip and would perhaps have avoided a few attempts to get fuselage halves without the sand dunes that I got round the bottom of the moulds when I had a go. Great work all round!!! Paul

  4. Modelling from another planet, Marc!
