tolerance you want them straight and flat - they straighten
them before they put it into the last process.

Thanks for the compliment on the machining!
I’m aware that you cannot hard anodize 2024. I was looking for a cosmetic clear finish, which you can’t get in hard, regardless of the grade of aluminum. I got exactly the color/sheen/look I expected, and can find no fault with the result.

>Erm, I don't know what to say. Maybe some pictures would help?Nice looking machining job.
>>Ive had 2024 anodized with no problems.OK - it anodised, but what color were you aiming for ? The light
grey color of your triple clamps is about what I got when I had
2011 & 2024 anodised matt black - whereas 6061 came up jet black.
Along with not taking color, anodised 2011 / 2024 doesn't surface
harden up much either. Anodised 6061 will blunt HSS drills after 3
or 4 holes, I've never had the same problem in anodised 2011 / 2024.
I stand by my original comment - it doesn't anodise at all well.
