How I Modeled The Knight Bus from Harry Potter and The Prisoner Of Azkeban
Using Wood Carving, Vacuum Forming, Plastic Shaping, Painting, Special Building Jigs, Model‑Making and Custom Appliques
Chapter 6: Vacuum Forming the Fleet
From the previous chapter:
I created a tool in the shape of the indentation out of epoxy putty. I would use this tool to poke into the indentation during the crucial seconds the plastic is forming.
This is what taking apart the two-part pattern looks like. On the top photo you can see that the back half is partially pulled out by the screw — it was a tough pull.
Each forming shot was fairly tedious, requiring that the pattern be assembled, formed over, “indented” and taken apart each time. It added quite a lot of time to what is normally a very quick process. I must admit this is a bit further than I get with most of my kooky projects, so here is the fleet!
Here is a wider shot, showing all the pieces and parts up to this point.
