Gerard, thanks for your comments. I appreciate your honesty. That's why I posted here.Do you think you'd feel differently if the aluminum beams were made of black phenolic or G10 material?
Anodizing would be the ticket, but it is a surface treatment and would be milled away as part of the machining process.For now, the plan is to have 6 risers at ETAR--3 with aluminum beams and 3 with a synthetic material, likely G10 or phenolic.
