All The Cool Kids Are Doing It

I was looking to get a suppressor for my SCAR, or at least explore what is needed to do so, and found the following within Michigan's firearm laws (of course, this was released BEFORE it was legal to own a suppressor):

Sec. 224. (1) A person shall not manufacture, sell, offer for sale, or possess any of the following:
(a) A machine gun or firearm that shoots or is designed to shoot automatically more than 1 shot without
manual reloading, by a single function of the trigger.
(b) A muffler or silencer.
(c) A bomb or bombshell.
(d) A blackjack, slungshot, billy, metallic knuckles, sand club, sand bag, or bludgeon.

And I'm cutting it off there. Because I need to know what all this cool shit is. Blackjack? Sand club? What the fuck is that? I don't know, but I WANT IT.

Heavy Machining - By Bay Cast Technologies

If a 10 foot diameter part is spinning at 19 RPM and you're cutting the outside edge, then you're cutting about 120 linear inches of metal per second. Coupled with the right feed rate and depth of cut, you've got these bullets rocketing off the part. The cross-section of the chip is approximately 1/2" x 3/16"... so we cut about 1.5 lb per second. Holy shit.

A 1/2" x 1/2" notch get cut off the entire rim of a 10' diameter part in about 5 seconds. We had to shut it down because it was too dangerous.... lol.
