I have a harbor freight vibratory tumbler, and i am just wondering what a good medium to polish up aluminum scales are, i have tried the green 1/4 pyramids, and also the 1in grey triangles. They are ok, but i am looking for an almost mirror finish

What type of aluminum?
For bright aluminum I use dry rice though the crud will deposit back onto the rings/scales after to many hours.
Usually fallowing up with water and blue dawn dish soap and rinse them off in the colander.

i believe it is just plain aluminum that TRL uses for their scales, i mainly just want to polish up the edges, and give a little more of a shine to the scales themself before i make a shirt out of them

You may be talking walnut-shell media and a buffing compound put in it, then, for the shiny-shiny. Tripoli, rouge, something like that. Walnut shell tumbler medium may come with this already mixed in; I have no idea. Tell the clerk you're polishing aluminum, for that may make a difference in the best buff-stuff. Ammunition reloaders use this medium to make their brass shiny before they run it through the reloading press.

Yes we do, and Harbor freight sells fine and coarse walnut shell media. You can also try corn cob media. It's softer than walnut shell.

Depending on how rough the surface is, you might want steel shot and water/detergent instead for greater burnishing power, which I have used with success provided I change the water ~before it goes dark grey.
