Hi

I managed to gibble one of my pieces of 1” x 1” X 1/8” aluminum stock fabbed into a tail cone part. IS there anything *special* about the aluminum stock used by Vans or can I just go and get some from the Home Deport Aviation department.

Inquiring minds need to know.

I have no idea what they use in Home Depot.. I don't think its 6061. I
don't think they even label it!

I would skip that part for now, order some more from Van's or Spruce and
do it with known materials...

Les

It looks like the part you are refering to is an aluminum angle that helps attach the HS to the tailcone.

Probably should get more material Van's.

Lowes and Home Depot do not sell aviation quality aluminum as far as I know. As a matter of fact, I don't know what alloy or temper the stuff is at the home stores. Buy from Van's or Aircraft Spruce the correct raw stock, the stuff at Home Depot is only good for aluminum windows..

I tried welding the aluminum found at the Aviation Department of HD to create a carriage with heavy duty castors for my growing tool box. It was clearly junk aluminum and I won’t go there for aviation grade structural parts.

You will notice too that the home depot/lowes Al does not have a nice fillet in the corner as the aviation grade.

As Chris pointed out, the aircraft grade stuff will probably
have that fillet. Also, I bought some hardware store stuff
for use in the shop, and I'll tell you it was much more brittle
than the aluminum from Vans. I decided not even to use it
for my vise jaws, because it just was not nearly as good
in quality. There's no way I'll use anything but aircraft
grade aluminum for any of the airframe. If the parts you
messed up are those L brackets with the odd shape, don't
feel bad, I botched mine too on one side. I ordered a foot
of material from Vans and re-did them. You will always find
use for extra aluminum angle in making brackets for things
as you get into the fuselage/panel/finishing kits, so plan
to stock up. Buy a couple of 6' or 8' pieces of the
common 1/16" and 1/8" stuff too...you'll use them.

John,

I heard a rumor that you didn't particularly like the aviation aluminum currently being used by Van's and were now formulating your own alloy specifically for the RV-10! Is there any truth to that?

If not, my bad.

I am late to this discussion so this may have already been said. Aircraft
Spruce has a catalog entry that explains metal specs for avaition. Van's
kits contain primarily 6061T6 and 2024T3 AlClad and a small amount of 3003
in tubing for brakelines etc. Pages 66-67 describe all and extrusion is even
defined for angles on the top of page 71. check

The Lowes/Home Depot aluminum IS 6061 aluminum but there are two problems with it. First, they do NOT specify the temper so you have no idea if it is T6, and second it has NO radius on the inner sections like the Van's stuff. Try spruce, just avoid the stuff that they have that also has no inner radius. http://www.aircraftspruce.com/catalog/mepages/alumangle.php William Curtis http://wcurtis.nerv10.com/ [quote][b]

Hi

Thanks for all the info. I found a local metal dealer who sells aviation
grade aluminum and am now the proud owner of 2' of the 6061 stock I
required. Unfortunately they only had 3/16" and not 1/8" thick stock so I
will check with Van's on Monday to see if there is a problem using thicker
stock (I can't see why as it will fit).

Cheers

Les

I do have a close friend who manages one of the world’s largest anodizing operations but my aluminum foundry pot lines are down due to exorbitant electric rates from all the RV builders working winter hours. Since VAN is down the street and the QC on such products are acceptable. I no longer patron HD Aviation Department for production parts.

William

I am getting a very fast education on a/c aluminum. The stock I purchase is stamped ASTM B308 which means it is 6061 T6 stock. As well, I made sure that there was an inner radius as well.

Cheers

Les
