Microstamping/Microetching Firing Pin

To steal ideas from one person is plagiarism, to steal ideas from many is research

Now that I'm a civil type and not a 39 hour a week quasi civil servant (wish I WAS hired for the 40 hour tenured life then, &^%# politics) and have to work for a small company, this research stuff is actually hard. I dont have the formidable research library and computers and support system I had then. Its me against the world, and Google is my only friend, and Google is a poor, cheating, mistress compared to SciFinder Scholar and OhioLink and Internet Two. The system is set up to favor the PhDs and schools, its now 20-30$ a paper just to read 4 pages, when before I could have 10 papers and 400 pages with a click of the mouse.

Upps, you guys are not supposed to know about Inet II, Security will now enter 2 divorce settlements in each of your names if you have read this thread. They dont kill you any more. your new ex spouses and kids just show up with court orders.

Dont worry about the NWO Pat, they're broke like us. The Chinese won.

nothing you do short of shaping the whole pin and its reciver pin in wierd ways is defeat proof, and pins are about 10$ and can be made in any machine shop, or with a home lathe that costs 350$ from the chinese.

How about etching the inside of the barrel in a characteristic way? This is something all the forensics labs look at anyway.

Barrel tols are tight, unless you want to impare accuracy or safety, there is not much to mess with. You can tag the brass easier.
In fact that might be a way to do it, barcode the brass with inside impressions(scratches) when inserted. Static chamber pressures are high, and pressures during insertion in a semiautomatic are insane. Your talking 2 or 3 thousanths of a inch , just enough to get a sliding fit between the brass and the chamber. The bullet into the barrel is a slightly oversized friction fit, and you have to drive it home hard before firing.Folks wont take kindly to anything that causes a stuck round, so that bar code had best be carefully done. Stuck rounds scare me when they are half inserted and a slide hits them.

That CSI rotational matching stuff pretty much only works on jacketed slugs or slugs that land in something that gradually deaccels them, like a 2x4 or thick plasterboard. Plain lead bullets are mostly hollowpoint, and there is often little left if they hit a bio target, depends on the slug design, velocity, and target . Jackets usually unwind into a strip or disk if they hit something hard and retain the marks, but sometims they just shatter.. At my old gun club, the club president often tried to find miscrients by "rewinding" the copper jackets, which usually sloughed off the lead when they hit the armoured backstop, He could usually determine caliber and thats about it, although a few guns produced distinctive marks where the cartridge expanded at the lead/brass interface.

You still need a cerrotrue cast of the chamber or a identical fired round to do a match.

taser uses a plastic tagging system, and that low a velocity it works, and they have room in their cartridges.

One easy way to find if someone fired a gun recently is neutron activation analysis of a paraffin cast of the hand, but one wonders if we have enough open frame research reactors left in the US to do it. OK, some quick googling indicates a reactor is nt always needed.

Nah... I think Pat was talking about the OP's neck, not yours.

And I do understand where Pat is coming from. Although I'm not a gun owner at present (and anyone that knows my history will understand why), I am nevertheless virulently *against* gun control. There may well come a time in my life when I want to have a firearm in the house, and I will vote to protect that right even if I choose not to exercise at the moment.

I appreciate all the feedback. I am here because the countless calls to manufacturers or resellers come back with "this is proprietary information, we can't give costs of any equipment unless we verify you are a firm which uses lasers or the vague but probably true: there are a ton of machines capable ranging from a couple thousand to hundreds of thousands"

Therefore, since professionals in the field do not wish to waste their time or efforts to help me "on-recordr" maybe some would be able to help me "off-record".

I do not doubt that there is more information and dedication on the subject from aficionados here than from the sales person over the phone.

The argument I am trying to make is that it would cost a ridiculous amount of money and effort for a false sense of safety. Perhaps a cost analysis with actual figures of prices of equipment from some manufactuers/model, accessories, etc. like MIXEDGAS has helped me with will be able to build a better argument against the implementation of such a law.

Any additional, and even better, more specific information or where I might be able to find such information, It would be much appreciated.

yes, sorry for confusion elektrofreak...i did mean the OP for even suggesting even the slightest hint for methods of further eroding our civil liberties afforded the people by the constitution.

(however, I dont blame you for having your guard up )

there are RFID chips in dogs and cats, and I just saw an article where they were going to insert them into cattle and horses...it is only a matter of time until they insert them into "sheep" - all new passports have them and there are cameras on every corner in Europe.

[viperdark]

that laser is upwards of 30,000 used, more like 70,000 new.

...not counting the acid etch bath, photoresist, and the machinery to cycle the pins through. ...

Does anybody have an idea how much this this part of the procedure would cost more or less?
and again... Thanks for everyone's feedback!
