Just looking at firing up the lathe and machining a gear knob, some door lock buttons and maybe a few other things but Im a bit unsure what grade of alloy Id be best to buy?
Im looking on the site that Ls2lxhatch posted- http://www.quicksale...uts-galore.aspx
Can anyone help me out?
I can always duck down the road to metaland and grab some lengths of round bar to use, but the price of the online joint seem cheap enough to make it worthwhile ordering from there.
Best alloy grade for making interior and underbonnet parts?

Look online for the machinable properties
And also corrosion resistance
2000 series is strong and easily machine... but very low corrosion resistance
6000 or 7000 would be ideal
But s I say... check the properties of each

Another source of alloy offcuts.
Motorsport Connections sell offcuts from the manufacture of Speedflow fittings for $5.50 per kg. I usually buy a 3 kg express post bag. I think most of it is 6061.
They range from about 10 mm through to around 60 mm. Typicall length is around 80 mm. They come in handy for making spacers and other small bits. Usually you get a mixed bag but if you are luckly they will pick out what you want.

Yeah go to 6060 or 6061 - they take and hold a polish much nicer than the 2000 grades as Datto says and they also machine and weld superbly and can be heat treated. Pretty good all round.

I made a bunch of little things for my car...used 6061 for coil mounts, clutch reservoir mount, assorted mounting blocks/plates, trim plates, etc.
I just have a few big chunks (1"+ thick and 8" or so inches square) along with some smaller assorted pieces plus sheet, etc that I make stuff out of.

I recently bought some plate (6056 from memory) from a mob called Ulrich Aluminium. It was about $100 delivered for a piece of 40mm plate about 300 x 300, they'll cut whatever size you want. I'll definitely use them again.

You can always get shit clear anodized, I got my horn button, shift knob and shifter collet that I spun up out of alloy clear anodized and they looked great with no maintenance, just a machined finish though rather than a polished one.
