Like that one :thumbup:. Could even powdercoat it black.
I would probably go with 6061-T6, It has been used prior and works great. I wasn't specific in materials yet as this is just a feeler.Can I ask what grade Aluminum you will be using? There really isn't such a thing as "Aircraft aluminum". It's more commonly used in marketing schemes to make you think your getting good stuff. Aircraft use all different types of aluminum, but for structure mostly 7075 grade is used.
