Default soft aluminum for sale detailing

Gentlemen, does anyone know of a source for aluminum that can be hand formed with a wood dowel. I have sent many e-mails to different suppliers with no reply for what I need.
I'm looking for 12 x 12 x .025 inch aluminum that I can drill and rivet on to the cowl and then hand form it over the cowl.
I figured maybe 5052-0 aluminum would work for this but can't find any.
Maybe another grade would work, would appreciate any help with this.
Thank you!

Thanks Casey, They don't have anything like this at our home depots in Florida, they use a very hard grade of aluminum for general purpose. Ace Hardware comes the closest, but they want 25 dollars for a small sheet.
I have found a lot of aluminum on line for about 4 to 6 dollars, but the companies selling it can't recommend what I need, they just look up the part that you order then send it to you, they know nothing about the product that they sell.
I need to know what grade of aluminum would work for this application, if anyone has had experience with purchasing a certain grade. Thank you!

Does anyone know possibly what grade the cowls are made from, that aluminum seems to be soft enough to hand form, at least my BUSA cowls are.

O material is what you want, weather it be 2024, 7075, or 6061. Are you looking for a 1ft. square at .025 or a different dimension?

You can use almost anything in a pinch, just anneal it first.

If you have a set of torches,
1- light the acetylene only and blacken the piece of aluminum first.
2- set the torches to a cool neutral flame and heat the aluminum evenly until the black has disappeared (this is the tell-tail that you have reached the correct temperature)
3- quench the aluminum

Or 1100 H13 is super soft.

Thanks Barry, that is what I thought but wasn't sure as I never used that grade before.

Thank you Peter, I have considered an acetylene torch but have got by on MAP gas, do you think MAP will heat it hot enough?
Thank you for the tip on the 1100 H13, I know were I can get that.

Check the roofing section of Lowes or Home Depot, for aluminum "flashing".

Try McMaster-Carr. I live in Florida and there are several placed in my area where you can get aluminum in all kinds of grades. I've never looked for soft aluminum because I go in looking for aluminum to make landing gear from. I'm in the Hernando/Pasco area.

Hi , if you do not have access to acetylene , you can rub the aluminium with domestic soap ,then heat up until soap turns black ,indicating annealing temperature . Map gas will work but try to heat the sheet evenly

Go to your local newspaper shop or printer. They will usually sell you there used litho plate at scrap prices or just give it to you. This is the perfect aluminum in my opinion. I use it a lot for exactly what your describing.

Roof flashing worked well for me.

I bought mine at Menards. I think it was a 25' roll, but they had various widths vs length combinations.

Tom, That is exactly why I'm looking for the softer stuff, so I can do what you did.
Beautiful job, I like going the extra distance like you did, to make these planes look like they are supposed to.
I will check out the roof flashing, Thank you!

Gary, Thanks for the soap idea, I had forgotten about that trick, getting old is not fun.

Steve, all our print shops have gone out of business and the local newspaper can't be bothered, I tried that first with no luck.
The local hardware type stores used to carry a good line of aluminum, but they claim that there was not enough call for it and discontinued the product, all they carry now is the heavy stuff.

Thanks guys, these are all great ideas, I really appreciate the help, Thank you again, Sincerely, Ron

Ron, after re-reading your initial post, I may have mislead you. My cowl is fiberglass, with a Flite Metal-like product applied to it. This was my first time working with metal, and I wasnt comfortable in trying to make the cowl from aluminum, but I believe that it could be done.

I used a variety of tools on the flashing. Tin snips, of coarse. I used the handle end of an x-acto knife, wood dowels, Sharpie pen handles, etc. The aluminum was easy to work with. I think that you'll enjoy it.

I believe that I paid around $12.00 for the 6"X25' roll of flashing, so you wouldn't be out too much if you experiment with it, and then discard the idea.

The flashing can be used in many areas of our models. I used it to hide the joint between the fuselage and wings.

For a cowl, it may be a little easier to use a metal foil, instead of screwing metal to it. This was my first time using it, too. I found vids on You Tube that explained the process.

The aluminum roof flashing from home depot worked great on making parts for my P-47.

Default soft aluminum for scale detailing




Fellas, Maybe I should have included a photo in the beginning.
I need a minimum of 12 inches x 12 inches, you have set me on the right track to find what I need.
As you can see, after the cowl ring is riveted on, the aluminum is hand rolled over the inside of the cowl just like the full size aircraft, I use a 3/4 inch wood dowel for this.

Thanks for all the great ideas.

You want 3003-0 if you are going to a metal supply like Metal Supermarket. McMaster Carr has it p/n 8973K19 .025 X 12 X 12 $3.62 PH# 1-330-995-5500 . Give them a call I buy from them all the time. Their catolog is 3" thick and they have just about anything. Let me know how you make out.

Thanks Mike, I will take a look at the flashing that Tom suggested, it looks like that may be just the ticket, if not, you have just the right stuff I was looking for in the beginning.
Thank you for looking up the part number and all the info, really appreciate all the help with this, I will get the McMaster Carr catalog as I need thick wall tubing to make scale landing gears and many other details for my planes and of course when the guys see these things, they want one, and I will end up making more than one, us kids never grow up. Ha!Ha!
