	~~'''Project name & pitch:''' <and any additional details>~~		== Additional Details ==

	~~'''Storage location:'''~~		A magnetic tumbler is basically a container with magnetic stainless pin shot and some water inside ("shot" meaning tumbling media), that swirls around in a metal tornado, cleaning, polishing and burnishing any small parts you put inside. Good for brass (cartridges?), jewelry, machined parts.

	'~~''Project start date:'''~~		The science is pretty low tech. Below the container you have a motor & spinning plate with magnets on it. Then a thin acrylic sheet, and on top goes the container. There's no mixing apparatus inside the container; when the magnets below the vessel spin they take the nearby pin shot on a ride with them and drag the media across the pieces being tumbled, flagellating them at high speed.

	~~'''Milestone 1~~:~~'''~~ <~~if any>~~		https://www.youtube.com/watch?v=M1OXh26hogQ#t=135s <-- Oooh, ahhh.

	'~~''Deadline 1:''' <if any>~~		One the size we're building costs ~$2200. The guy in the video above says $150 to build his.

	~~<Milestone 2: etc>~~		$150? Nope. I think we'll build it for $0.

	~~'''Final Deadline~~:'''		http://www.rchristopher.com/tech/tumbler.html <-- Rough build plan if you like following concrete plans. I talked to this guy a few years ago, I don't think he really understood how magnets work (Magnets? How do they work?) so I'll improve a bit on his design.

	~~==Updates==~~		I've built three 95% of the way in the past. Last time I built one my idea of machining was "jigsaw & hot glue". PS's resources can do better.

			Partslist:

			- Frame (junk wood/acrylic)
			- Induction motor (Jorgen donated a few, + there are others)
			- Plate (someone will fab)
			- Magnets (how do they work?)
			- Top deck (scrap acrylic)
			- Bowl/bucket/octagonal container for enhanced tumbling (scrap acrylic or bucket)
			- Power switch/cord/etc (lots)

			All that leaves is the non-consumable pin media, which I have a source on for about 10% the cost of buying it from a normal supply place. And I have some to test with.

			Oh, and the magnets will probably be hard drive magnets. Wes has a stack of dozens which I saw and is what reminded me of this. Wes plans on building one for himself, I think, or just the space, not sure. Either way, I can strip extras and it's not a lot of work to make one for the space.

			Bonus Science:

			Why use this instead of a traditional rotary/vibratory tumbler? A rotary tumbler is speed limited to gravity, you can't spin it faster or nothing actually falls and tumbles. Vibratory tumblers are loud and shake a room and are very slow. This is somewhere on the order of 10-100x faster than either of those because you can force the shrapnel tornado through the workpiece as fast as you can spin the motor.
