How-To:  Rifle Shell Pen Body

How-To: Rifle Shell Pen Body

I have before identified Instructables user Mrballeng as a craftsman’s craftsman, and this latest offering only serves to reinforce that opinion. His work is not flashy or complex, but it’s always thought out with exacting detail and does amazing things with everyday materials. Here, he uses a mini-lathe to bore, swage, and align two .30-06 cartridge cases before soldering them together, at the joint, and fitting the guts of a refillable plastic click-pen inside. Cool stuff.

When I first saw Chris’s gorgeous brass-and-wood irising door peephole mechanism in the ShopBot booth at Maker Faire, I knew it was something special: A beautiful piece of machinery, designed and built solely for the pleasure of operating and observing its operation. When Chris contacted us wanting to sell them in the Makers Market, naturally I was excited, but I was also a bit skeptical. I couldn’t imagine that such a large, relatively complex machine of solid brass and wood could be manufactured and sold at anything like a reasonable price point. But the $285 Chris is now asking, while certainly not cheap, is about 40% of what I was expecting to see when I clicked on his listing. I will be surprised if he can afford to continue selling them at that price. Which is why I already bought mine.
