Re: How is this legal?

Where the hell are you getting your information? The gents on subguns determined this to be the case, I agree with their analysis, and has been legally done on other weapons in the past. The ATF concluded that a trigger release was essentially the same as a trigger pull, and considered as "a trigge...

Re: Interesting .22LR Micro Can build...

Keep up the good work.

A home shop normal anodizing without color is actually pretty easy. All you need is a source of DC voltage that can be controlled, some battery acid, a tank, and preferably some sheet lead for the cathode, although other materials work.

Re: Awesome home anodizing setup.

What controlled parts are you talking about a pain getting anodized? We anodize NFA all the time. Bendersquint, you're still (hopefully) going to be my "go to" guy when my .22 belt fed project needs anodizing. I really want a quality hard-coat job. I emailed U.S. Anodizing twice, before I found out...

Re: My Form1 transforms into my first can!!!

I doubt Metalman is still around, but the slots were apparently designed so each baffle, when rotated 90 degrees, would snug up with its neighbor, and the threaded rod compressed them all together for the weld. This sucker is built like a tank. I have really only one objection to the mount, and that...

Re: Awesome home anodizing setup.

I've looked at it a bit. The temperature is the problem. You need a refrigerated tank to do it correctly. The salt water aquarium trade has chillers that consist of a titanium probe that you could immerse in the tank, and the refrigerent runs right through the probe, but these are scary expensive. P...

Re: Distillation for SHTF

Well, nice is relative. I'd rather be allowed to have a bunch of silencers on hand than not. Obviously the best case is a bunch of silencers (and MG's too) and be able to use them. I think New Zealand allows one to have ANY machine gun made, but you can't shoot them. I wonder how much <wink wink> go...

Re: How is this legal?

AFAIK it's one shot on trigger pull, one on release. This has been legal in the past on the mini 14, IIRC. One problem. You pull the trigger, BANG, but don't want to let even one more round go, and now the trigger is depressed on a weapon that is like a hand grenade with the pin pulled. Let go of th...

Re: Building a lab-grade Temperature Controller

Time to wrap this thing up. On the schematic, take care to note that some of the wires are drawn heavily - these wires at a minimum need to be able to carry the full current of your heater(s). Since many controllers accept 100 to 240VAC, the entire unit can be wired to 240 V, giving you the same wat...

Next to the controller is the heavy fuse block for the output side of the SSR. When I say "ouput" in these postings, I r...

Re: Building a lab-grade Temperature Controller

4) Buy a Master on/off switch of good quality - I used a beefy toggle. I also added a 120VAC lamp which can be seen upper left. This is optional, but I am very glad I did. This lamp is wired so that when the high-current heater output is energized, the lamp is ON. It not only warns you that the term...

Re: Building a lab-grade Temperature Controller

The size of the SSR: Amperage is roughy determined by the simple formula W= V x A, where W = wattage V = voltage A = amperage, current So a 50 amp SSR using 120VAC can theoretically handle 6,000 watts. Note that most household 120VAC lines are fused for 20 amps, so if you think you are going to be t...

Re: FA .22LR options?

DIAS's these days are selling for well North of $20K. Probably the absolute cheapest registered receiver would be either a big-hole converted Colt Sporter, or a PAWS or Oly RR. It's possible with a little effort to find one for $12K I think. Probably $14K is more realistic. Machine Gun Price Guide h...

Amazon isn't clueless, they just don't care. They sell all sorts of stuff that could be classed as drug paraphernalia as well.

And honestly, I appreciate the fact that they don't care. Do we want more companies like eBay that prohibit "high-capacity machine gun clips" and the like?
