zyklon-B distribution kits

[jono035]

Metalcorp has a buy price for scrap brass listed as $4.50 per kg, so at 1/2 scale that is $800 of brass... Crikey.

Apart from that, the rest seems disturbingly do-able. I've found a couple of places with plans for making:

Waste-oil powered burner (centrifugal blower and oil line basically)
Furnace (shell, can be sheet steel, some form of castable refractory ceramic material, that's just a buy-it deal)
Crucible (can use steel, brass melts at 900-950 degrees)

The actual mold process itself is a toss up at the moment though, some form of lost wax mold could be used by casting a big cylinder of wax and then turning it on a lathe to get the shape right (steel rod in the center) then layering the refractory ceramic around the outside and packing it in a crate with sand... would be a single shot thing though...

Indy - This is a link to the gun city ad showing the Norinco SKS rifles for 399 and the M14 for 599...

Also a Marlin 30/30 lever for $1k

And they're still selling USCs, SL8s and G22s as A-category, gotta love it!

Haven't done any sand casting for a while, and never anything that big.
Talk to South Auckland Foundry, Hunua Road, Papakura.
It will not be cheap.
Home made cannons I have seen previously use a welded up heavy wall pipe liner as the barrel, and the barrel is cast around this, so you are not really relying on the casting for much.

Ahhh, that makes a bit of sense actually, seems a little like cheating though!

Would be keen to take a shot at casting something myself but I'm sure as hell not starting with something that weighs 200kg... Maybe something that weighs 500grams and shoots ball bearings perhaps...

[jono035]

Just went through and sorted all my saved 9mm brass.

1246 Federal American Eagle cases, all once-fired.
56 other random cases

Pretty decent little cache to start reloading from I think... Tallies up at just over a grand spent on pistol ammo and about 1500 rounds fired total, not a huge amount compared to a proper target shooter but still...

Might go get myself one of those Frankford Arsenal case tumblers tomorrow to get some of this stuff cleaned up and ready for my press to arrive...

[Indiana_Jones]

That's a lot of brass lol
