I thoroughly enjoy mechanical things—I’ve always been fascinated with the inner workings of watches, engines, and locks. I was that kid who would fearlessly take all of the screws out of toys and electronics in an effort to understand how the guts of the thing work.

So when I received a heads-up that I would be doing a lot of work on the Convergence faction, I was very pleased. I knew I wanted to match the functionality of the concepts by Andrea Uderzo as much as possible.

When it came to the Prime Axiom, I really wanted to duplicate as closely as I could the way the drill claw is intended to work.

When I initially modeled the arms, the drill part was separate from the arms, but the parts had to be combined to keep production requirements under control. If you happened to wander past the digital sculpting area at Lock & Load last year, you may have seen the Prime Axiom I had modeled with the fancy closed claw.

In this Insider, I’m going to show you how to put together this simple conversion to add a little variety to your own Prime Axiom.

Here are the parts you’ll be working with:

Step 1: Place your clippers as pictured with the angled side of the clippers pointing toward the claw arm and the flat side of the clippers resting on the back of the drill piece. Then clip through the arm.

Step 2: You’ll notice that the arm side of the part where you clipped the drill off is now wedge shaped. Clean up the pointy end of the wedge with a file or sandpaper.

Step 3: Using a P3 pinning kit, drill a hole in the elbow side of the wedge pictured below.

Step 4: Now drill a hole in the opposite side.

Step 5: Add a pin, and glue the parts.

Step 6: Rinse and repeat for the remaining claws. Glue the tip on the dome piece.

Step 7: Line the three drill parts up and grip them loosely on the drill end (do not glue these yet), and then place the dome-shaped part in the grabby claw formed by the three drill parts. Then, apply a drop of glue where each arm meets the dome-shaped part. Hold this until the glue sets.

Step 8: Once the glue has set, place the assembled piece on a flat surface and apply a small drop of glue to the tip of the drill.

And there you have it: a fully assembled, closed Prime Axiom claw!
