Good roof rack???
Guy that is helping powder coat my custom L&L bumper is willing to sell me a roof rack he used at one point but since he no longer has a 4x4 vehicle he wants to sell it. It's an aircraft aluminum custom roof rack that would fit my XJ perfectly. I'd like to know if the material is worth the money he is asking.
He wants $300 for a 55"x72" aluminum roof rack that he would be willing to powder coat any color of my choice AND he will custom fabricate the mount. All that for $300. Is it worth it?
It will either be this roof rack or I would buy a rear bumper with a tire carrier. The rear bumper would cost $800 with shipping but that could also come down if I have this guy fabricate it for me.

the aircraft aluminum is really expensive so idk how he can get it for that cheap. i just replaced a panel on a aircraft at work that landed without the gear down. the piece was the same size and shape as a old ****** jeep hood. just that piece cost us $40,000 to get before we replaced it.

What I have found out is that this guy used to operate out of Florida and has always custom fabricated parts for vehicles and boats or just about anything a customer can come up with he could do it. Now for boats he would use high quality aluminum due to its strength and resistance to salt water. This particular roof rack was his own and when he made it he used the best aluminum he could buy.
The type of aluminum used is 6061-T6 Aluminum and from what I've gathered it is a material that can be used for aviation. Now the further that I researched into this I found that the aviation industry actually uses for the most part all types of aluminum grades. Everything from aluminum used in everyday manufacturing to extremely expensive and high end aluminum. So it goes without saying that all aluminum is aerospace aluminum and kind of makes it a moot point now.
And just so no one really argues with what I've said above read the following thread\quote:

Sorry to laugh, but I do every time I hear the "It's Aircraft Grade Aluminum" description.
Aircraft can and do use every alloy of aluminum. For a bit of insight into the hows and why's of material selection and a few good insights to the art of bending aluminum without the cracking read through Chapter 4 of AC 43.13-1B

Now I am sure that there are more than a few that will take exception to the welding data, just remember that this is the regs for aviation. Industrial standards may and do vary. The material data is accurate for all however.
If you managed to read through Chapter 4 and would like to see some other useful information or just cure your insomnia. AC 43.13-1B - Acceptable Methods, Techniques, and Practices - Aircraft Inspection and Repair Complete document index page. http://www.faa.gov/regulations_polic...umber/43.13-1B
Some wise words passed to me by an old FAA Examiner during one of my Oral Exams when he asked a question that I was unsure of the proper answer for.
"I think you are having memory problems. Do you want to look it up?"
I says "Yep, if I could. It should be in AC 43-13."
"No need. That's the answer I was looking for. The problem is when you don't know the answer and you don't know where to look for it. You got that one right."
