Revell 30 Model A Top Chop

Since I was able to acquire another copy of the Revell 30 Model A kit I wanted to cast it as the two part body. There where some requests about different roof heights an it was gonna be easier to master different roof parts an make molds than the one piece body I previously had done.

After trying to cut, glue, an finish a resin copy with little success I had to think of another way. It came to me that if I could make a mold of the bottom of the top then I could slide in a top section cut down into the mold as resin is curing it would give me an exact fit.

Step One: Make A Mold

First step was to suspend the top in a mold box so it was level. I use Lego’s for my boxes so this was pretty easily done. I mixed up so silicone an poured it into the mold to just come over the bottom of the rear window.

Step Two: Getting The Part Out

After the silicone mold had set up it was time to cut the part out. No problems getting it out an then just had minor clean up on the mold.

Step Three: Casting The Roof

I had a resin roof that broke when taking it out of its mold so I cut the bottom of it. Then it was just a matter of pouring resin into the mold then sliding the roof down in.

Step Four: Now That’s A Chop

After giving the resin enough time to cure it was time to take the part out an see if it worked. The resin doesn’t actually bond to itself so I was able to clean up the extra resin. It did have some air voids but that is something I can fix by putting resin into the holes to cure. After some initial cleanup I think it is gonna work.
