Need help, Titanium / Carbon Fiber / Aluminum

[MrForbes]

It might be wise to do a bit of analysis on the existing part, before going to the trouble of redesigning the whole thing. What is it made of? We know it's aluminum, but what alloy? Maybe all you need to do is to go to a stronger alloy, especially if what you have now is just generic hardware store material.

Also I didn't see any mention of using steel, which might be a mistake, as thinwall chrome-moly alloy tubing is very strong and light, and relatively easy to work with.
