Hey folks, I'm looking to try my hand at working with some AL on some future builds. But I have a couple of questions for the folks that have worked with AL already. I've read some topics here, but info is spread around quite a bit, I'd like to compile it in one place for my info.
If you can help answer any of these, it would be appreciated:
1. Where are the best places to get AL in sheets? Online seems a bit pricey, and since I'm not practiced at purchasing metal, what are your best local sources for AL sheets at reasonable prices?
2. I know that, just like Stainless, there are different types of AL. Just wondering if any of you have a preference for a certain type. I'm not building any Schlocklay type stuff, so I don't need AL from the International Space Station.
3. While I've seen it discussed, I'm still unclear - what's the best way to polish/finish AL to help prevent future oxidation on the surface? Or can that even be done?
4. Best recommendations for cutting AL? I know I can use a hack saw and maybe even a band saw? Maybe a scroll saw? I've heard it can bung up your blades.
5. In my work as an electrician, I did plenty of drilling and tapping, but that was almost always in steel or copper. How well does AL stand up to tapping and holding a thread? Can I expect threading to be similar to steel, or are there any special considerations?
I know some of y'all are quite smart about these things, so thanks in advance folks!
