Anyone here in the metals manufacturing/fabrication industry? SRT R&D

While this topic will not appear to be SRT related- I ASSURE you, it is. Albeit, somewhat "top secret".

In short, I need to get a hold of some 13/16 ALUMINUM tubing. Preferably either straight lengths, or most desirable, pre-formed or mandrel bent tight 90's with extra straight lengths. (1.5"R) I am having one hell of a time finding this stuff, as it is an oddball size.


Any help would be greatly appreciated, and I promise- this is for a MUCH needed product for these cars!

Re: Anyone here in the metals manufacturing/fabrication industry?

Sounds like an air conditioner part.

Did you check with McMaster-Carr, and Grainger?

Are you referring to the i.d., or the o.d.?

McMaster lists both i.d. and o.d. sizes in their descriptions. Look at page 3420 in their on-line catalog. If you can't find the size you need, maybe it would be easier to switch to a size that is commonly available.

Here is some stuff on it, more on their website-

Extra-Strength Aircraft-Grade Aluminum (Alloy 2024)
Superior strength and good machinability. Most widely used aircraft alloy. Addition of copper improves strength but decreases corrosion resistance. General Purpose Aluminum (Alloy 3003)
Higher strength than Alloy 1100 due to addition of manganese. Use in chemical and food processing equipment, tanks, heat exchangers, and sheet metal work. Multipurpose Aluminum (Alloy 6061)
Most widely used aluminum alloy due to combination of strength, good corrosion resistance, and machinability.
Ultra Corrosion-Resistant Architectural Aluminum (Alloy 6063)
Superb corrosion resistance. Perfect for outdoor applications.

Tolerance
Standard: Material is manufactured to a nominal dimension according to commonly accepted tolerances. Example: 1/4" Diameter ±.002".

Oversize:
Tolerances for width, thickness, length, or diameter are always plus (+), guaranteeing a minimum size of material above the given nominal dimensions. Includes "oversize cut" items guaranteeing a minimum length of material. Example: 1/4" Diameter +.0002".

Re: Anyone here in the metals manufacturing/fabrication industry?

Hello Vic,

Nope... not A/C...but that would have been my first guess too!

Yes, I have checked those sources. Unfortunately, they do not carry any 13/16 as far as I could tell. It is an oddball OD size at .8125".

Oh well, worst case scenario I have to have the mating surface machines to accept a readily available size. Only problem is added cost in doing so.

Re: Anyone here in the metals manufacturing/fabrication industry?

Did you try TW Metals in Rochester? (585) 352-3880, or your can try Yarde Metals in Ct. (860) 406-6061, one of these should have what you need!

Re: Anyone here in the metals manufacturing/fabrication industry?

Try Alcoa. I don't have the contact info for them but they are in Texas.

Re: Anyone here in the metals manufacturing/fabrication industry?

Hey Daniel,
I have an off topic question for you, since you seem to be a SRT guru. I have an new A/C compressor supposed to be for all the Gens (I, II, and III). Can you tell me, is the compressors all the same and if not, is there a part number that will identify it as for a certain car? Thanks for any help,

Re: Anyone here in the metals manufacturing/fabrication industry?

I moved this back as I think it was moved in error....sorry about that. I will now beg for a thousand pardons while holding my breath! Please, by all means...carry on.

Re: Anyone here in the metals manufacturing/fabrication industry?

.813 OD but what about ID size. Will check at the shop tommorow. Might have some laying around. If I remember well it has a very thin wall thickness. Cut to size.

Re: Anyone here in the metals manufacturing/fabrication industry?

99 R/T 10- The compressors used in the Vipers are Denso part number 10S17C, and they should be interchangeable.

Tony- Thanks again

Black 94- I need an ID of roughly .675"

Re: Anyone here in the metals manufacturing/fabrication industry?

I have some in stock now:
.83? OD X .61? ID wich mean wall would be around .11?
type 6061-"T7651" Aluminum

1 lenght of 78 inches.

+ a few around 12" to 36" (wild guess)

No elbows ONLY straight tube.

Will probably not have anymore, as it is not on inventory (odd stock). Most likely leftover from some previous jobs.

How about Stainless Steel ?

Re: Anyone here in the metals manufacturing/fabrication industry?

What are the exact dimensions of the tube you have in stock? (OD/ID) Is it .83/.61? How much per foot?

Hypothetical question: COULD you get more if need be?

Lastly, do you have any means of mandrel bending, or an outsource that can do it?

The tubes must be weldable Al as they will be welded to other Al parts. The use of steel would neccessitate a bulkhead fitting, and I do not think the crank will clear a bulkhead fitting in that location, that large.

Thanks,

Re: Anyone here in the metals manufacturing/fabrication industry?

"What are the exact dimensions of the tube you have in stock? (OD/ID) Is it .83/.61? How much per foot?"

If I measured correctly, I beleive it was .833 OD but it is not a machined surface so...and the ID would be .610

"Hypothetical question: COULD you get more if need be?"

AS I MENTIONED, IT IS LEFT OVERS from....BUT
I will check thursday if possible to get more and at what price !

"Lastly, do you have any means of mandrel bending, or an outsource that can do it? "

For that, I will have to talk to someone in that department that could tell me if & what could be done.

Outsource (bending), None that I know of!

"The tubes must be weldable Al as they will be welded to other Al parts."

There should be no problem welding specially with an Argon TIG welder and a good hand (we have the best in town).


How much would you need, global count ? Will hook you up with reasonable price.(for the on-hand stock) You also have to consider my location.

Re: Anyone here in the metals manufacturing/fabrication industry?

Thats sounds like it will work perfectly. However, please let me know if Mandrel Bending 90's with a 1.5" radius can be arranged, that would simply everything SOOOO much.

Generally, I would either like it pre-bent in 90's of possible, (I would specify orientations) but it would be about 1.5 feet per finished product. I would like to start with a quantity large enough to complete at least 5-10, as I know there is bound to be some screw-ups and practice on the first one or two. So, figure 15 feet should do it? cut to 1.5' lengths for easy shipping.

Please work me up a price+shipping whenever you get a chance.

Re: Anyone here in the metals manufacturing/fabrication industry?

Will get back to you with this tommorow night with more details.

Re: Possible bending, disponibility of material and price.

Re: Anyone here in the metals manufacturing/fabrication industry?

I am working on this now. Should be up here in few minutes

Re: Anyone here in the metals manufacturing/fabrication industry?

Ok. I got someone try bending this piece at work, with a tube bending machine.

Picture in my gallery.(don't know how to post here)

1: Notice the minimum bending radius that WE can do.

2: The bending machine will make some mark which you can see as small dots along the radius (could be polished out)I did not have the time to do it. (will try to put some tape on tube next time to prevent this)

3: MINIMUM staight stock is 7.5" from either end/ or other bends before bending.

4: I found out today that we still have a use for this tube, BUT we do not keep in stock. SO ONLY IF THIS WORKS FOR YOU,I will do the following:

Contact our supplier to know delivery delays.
Order sufficient stock for your convenience.
I will have to find out about shipping cost.
No minimum quantity.
Price sent by PM.

Re: Anyone here in the metals manufacturing/fabrication industry?

Hello Germain,

I pm'd you back. I cannot use that bend rd. unfotunately. the bend has to be 1.5", as the tube rides along a plate which it must clear.

I will order 10 or so straight lengths, and see what I can do with them. If they work, I will get something set up with you on a small-volume basis.

Thanks,

Dan

Sorry, I can't bend on a smaller radius. I do not know what you really want to do with this, but maybe there would be an alternative to the bending radius !

I talked with our supplier today. From order date to Shipping to you should be around 10-12 days.

Next step:

Will order stock when you give me the quantity you want.
Price I gave you + shipping charges.

You will have to get your full address to me. Email or PM.
Regular delivery or Rush delivery is up to you.
