Wednesday, eh? Good morning, GN.

Related to yesterday’s Defense Distributed article: https://www.wired.com/2014/10/cody-wilson-ghost-gunner/

https://ghostgunner.net/

“Ghost Gunner is specially designed to manufacture a growing library of mil-spec 80 percent lowers to completion. With simple tools and point and click software, the machine automatically finds and aligns to your 80% lower to get to work. No prior CNC knowledge or experience is required to manufacture from design files. Legally manufacture unserialized rifles and pistols in the comfort and privacy of home.”

What do you think, Mac?

Good morning, Sven; hai, Wheelizens!

Just got the internets back after a nearly 5-hour outage; feh.

Spent the morning working on numbers for that large job we were asked to bid; holy frijoles…it’s about $1.1M!!1! Really want to ensure that we don’t get shot down during Round 1 of the bidding process.

So far, I’ve been unable to make the numbers not make sense, so I’m confident there aren’t any gross errors in the square footage and/or pricing; I think I’ll work on something else and revisit that bid later today (or tomorrow morning) just to make doubly-sure Jim and I haven’t screwed the proverbial pooch.

I am very appreciative of the satellite-based take-down service we use on large projects; experience has shown their numbers are very reliable and they save a lot of roofing scut-work on bids like this.

What do you think, Mac?

I’m curious about that, too. (Defense Distributed is kind of like something out of a ’70s or ’80s near-future libertarian SF novel; I quite like that.)

BBL.

Happy Wednesday, Gerbil Nation!
Good morning, Sven, and Fatwa!

I rather like that Defense Distributed is trying to get their library federally certified so they can have microfiche copies of DoD small arms technical manuals.

Effective 1 July 2018, California requires that you apply for a serial number for any firearm you assemble, if it doesn’t already have one. I’m not sure if pistols have to go through the state testing protocol and must micro-stamp the cartridge in two locations (currently impossible), but I’m sure the rest of California’s firearm restrictions apply (loaded chamber indicator, assault weapons characteristics, magazine capacity, etc.).

Hey Mac! I’d be interested in hearing your opinions regarding the machine tool DD is selling, its capabilities, flexibility (e.g. must you start with 80% lowers, how much variation in the lower is allowed), accuracy, repeatability, etc.

Thanks for the info, Mac. From what little I know about machining -- which is 98% second-hand -- it would seem like any small machine would be unable to hold the tolerances for consistent precision machining of something the size of a lower receiver.
