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.

Thanks Dave, I'm glad you like them... the aluminum is 6061. It's an extra strength, corrosion resistant aluminum. For the door lock pins and other items I make, I use 2024 aircraft grade aluminum. I have thought about alodineing them and I would if it was an outdoor piece, but being that it is inside the car, I think it will hold up. But alodining does protect the finish forever... I used the 6061 aluminum because it has a better corrosion resistance than some other aluminum.
