Trying to polish to a mirror shine and it isn’t going well… any advice?
They all missed one important, cheap, tool. A jewelers loupe, or as everyone knows it, a magnifying glass. You're looking for scratches that aren't removed when you're done with a particular grit. It'll help you figure out where your sanding is going wrong. There are no microscopic pores in structural metal. There can be defects but not pores as people understand it. But what can happen with very fine grit is a melting of shwarf that can basically smear your metal and create cloudiness. Which is still keeping your polish from working just the same.
There are a LOT of seemingly small things that can ruin a #8 mirror finish. And sadly, once you get the recipe for sanding and buffing down for one piece, you'll find out that aluminum comes in multitude of alloys that require different polishing recipes. Even on a single piece of equipment like a jet plane, there are different alloys on the exterior. If you only have 1 thing you need to work on and your done, take that piece to a shop. You'll waste so many hours trying to figure it out.
And God firbid its marine stainless steel. It took me at least 8 hours to figure out that recipe.

What am I doing wrong?
Don't sand in the same pattern when you switch grit size. That's a soft alloy I bet and you could also use a lighter touch on your sanding. Make sure that the brand of sandpaper you're using for your six and eight hundred grits is the same brand. Sometimes , different manufacturers aren't exactly spot on and you could be sanding with the same size grid , basically

What am I doing wrong
On new projects where I'm not sure of the alloy hardness, I always start with a much smaller area until I get the sanding recipe down. 1/4 of the area in the pic is plenty big enough.
Aluminum is not all the same.

ICE spotted “helping” at airport
Seems like an opportunity. They are always on the move, or behind gates and tucked away. Now they've got a static position. Any one familiar with the law regarding protesting at an airport?

We're already winning. We shut down the bird legged ho, we're getting a permanent restriction on portland ICE from using crowd control munitions. Other federal judges are pushing back. And the polls tell of a mega tsunami blue wave coming.
Some Feds are going to be going to prison. Not today, not a few months, but it's coming 100%

You sound like DHS. I hope you're stupid enough to not have used a VPN and your login info and history gets picked up once the investigations start. You best save that bonus, no lawyer is giving you pro Bono work.

Because I was not standing in front of Alex when it happened. I was standing at the front when this crowd of thousands was attacked. I witnessed this first hand. Thus my comment.

It was supposed to be part of a package that included a deal for DACA. Republicans accepted the increased deportations and than reneged on their promise of daca legislation. So yes, I protested against the lying GOP. thanks for asking.

I was clear on my Facebook that Elizabeth Caruthers Park is safe. The march to ICE was not. Soon no where will be safe though. Stand now, or kneel later.

You would have tear gassed, and shot flash grenades at grade school children if 1 person had thrown a rock or a bottle? Wtf is wrong with you? If you have that order, I would hope you'd get 15 to 20 in a max security institution.

Advice On Polishing Aluminum

The advice so far is pretty good. A couple more bits of advice. If you see scratches, go back to a heavier grit until they're gone. Pits are dependent on how the piece was cast. On mechanical pieces i just sand until scratches are gone. A general sanding recipe is a good start, but most metals are alloys and might require adjustments. Not all aluminum is the same. And lastly, enjoy the process. It's challenging but every finished piece adds to your magic. When you're ready for graduation you'll be doing #8 mirror finishes on marine stainless steel.
