Henkei Megatron rear mounted gun barrel The third and final custom that Henkei Bumblebee helped me create was a modified Megatron. Now, I love this figure. But, clearly the wings have to go. That was the first step. Secondly, I'd seen a few people had used a shapeways part to mod their Meg and give him a rear mounted gun barrel (just like G1). I liked this idea but, one of the problems with the shape ways part is that it isn't functional. And, I wasn't as keen on that. So, I started trying to figure out how I could come up with something that could work in robot mode and gun mode. I was reading a comic called All Hail Megatron and that's where I got the idea. In this comic, Megatron has a black rear mounted gun barrel, which, is not exactly like the cartoon version (which is grey), but still looked pretty good and led me to my next custom. I bought a cheap classics Megatron off eBay and subsequently began butchering his Fusion canon. And, the interesting thing about the fusion canon is that it has a mounting that perfectly fits a ball joint (like, say, the one from Bumblebee's arm - or actually, by now it was Cliffjumpers ex arm after their swap). Also, on Megatrons back, there is a hole just right of centre which houses a screw. Whilst this hole isn't wide enough to house the other end of the ball joint, the joint can be filed down to fit the hole. And there we have it. A rear mounted gun barrel that you can swivel on the ball joint to get the right positioning in robot mode. The barrel is a bit wider than it was in the cartoons but I thought it still looked pretty good. I have now included a pic of the gun barrel mounted in gun mode. I was pleased with how it turned out as it seemed to compliment the overall design of the gun. Anyway, hope you like the idea.
