Chad,

Got the A/C rings today and they are now installed. Have you ever thought of Alodineing them? I will probably treat them with clear Alodine 1001 (haven't yet) that is usually used with electrically bonded aluminum parts on aircraft to prevent corrosion. It will also maintain the chrome-like look that you have supplied. What is the alloy and temper of the aluminum that they are made of? Just by applying a little "flex test" I can tell that they are made from something like 7075T3 or 2024T4 rather than O temper anything. You must have a nice CNC lathe and the education to use it to turn these out. My dad was a master tool and die machinist and inspector (50+ years in the business) before he passed away and I'm pretty sure he would have approved of your fine work. I certainly do! These rings fit up perfectly and the drop of super glue will probably never be necessary in my XFire.
