Reloading Protection

Once bitten, twice shy, so in the aftermath of my Glock K-boom, here's my answer to inadvertent double charging.
Shown here mounted to the top of my Lee 1000 press, this is a quick and dirty device to find those doubles and warn me about them before they get into my gun. I could have spent more tome and made something more elegant, and maybe this summer I will. This is a bit clunky and bulky, but it works.
The Lee press has only 3 stations but I've found the priming part to be kind of spotty so I don't use it. This leaves 1 station open. Decapping and priming are handled separately so this setup does first powder dispensing, second powder checking, and third bullet insertion and seating.

The wood piece is a plunger that goes down through a powder dispenser die in a caliber I don't use. When the powder filled cartridge comes up it rises about 1/4" if it's correctly filled, and about 1/2" if it's gotten hit twice. Inside the plunger are 2 Lithium batteries and the wires from the bright blue LED seen hanging out the left side.

If the powder level is correct, nothing happens, but with an overcharge, the plunger goes up far enough that the bolt presses the led lead down onto the top of the battery stack illuminating the LED. The operators seating position is off to the left in this picture, and the LED is pointing pretty much right at my eye and trust me, this little baby is bright. The spring allows the device to catch anything from a little over to a lot over without jamming the press.

The drawback is that the device is bulky and takes up space that might be used for adjusting the powder reservoir.  There is no doubt in my mind that this thing could be made to fit entirely inside a die with little more than the LED poking out, but that's for Rev B. Meantime I'll suffer.

Very clever - now to get a patent on it! :)

Everything on this blog is copyright:Me. I also claim, to use patent application boilerplate, any and all variations on this device including but not limited to different annunciators, power sources. materials and construction techniques. Thus a wind or solar powered device made from unobtanium that induces a spaz attack in the operator in the event of an overload would be covered. All that and more.

I'm pretty sure the whole thing could be embedded in a single die envelope and made from plastic cheaply enough to be labeled and given away at trade shows like ball point pens. Rights to manufacture this can be had very cheaply but act now! The Chinese have already seen this and will be giving them away with the Norinco logo on them at the next SHOT show.

Keep in mind that the Chinese version will automatically report all your production with the device installed, to the Chinese government. Federal and State entities wishing to obtain this information can get it with a nominal (7-figure) donation to the Lee Kee Data Corp, Hong Kong, PRC.

Your first generation version may be a little clunky, but there is elegance in simplicity and function.
