Default Mufflers...Soup cans that can be braze welded?

Everytime I walk through the can food section of a supermarket I see an endless variety of mufflers. I have experimented with some of them and I was not able to weld anything to them. I suspect they are a galvanized metal, which is preventing them from being welded with other metals.

Does anyone know for sure what a common soup can is made of and has anyone found something that can be welded?

Thanks

Norman

i think all cans which carry foodstuffs are plated,perhaps motor oil cans would be better.

Agreed, though the soup can (or most any other) would seem a bit large and heavy. What are you working on?

Try Stainless Steel as in Salt and Pepper Shakers...or Muose ah..er Mousse spray cans or old empty paint spray cans depending on the size you need..and hard solder with silver solder.
Its been done before..

My Pitts 3rd scale has a pair of stainless steel resturant salt and pepper shakers from Italy but you can find various sizes at Wal-Mart, also check the BBQ section...

I've got the plans for one right here on RCU..but for the life of me, I can't remember where on this pewter I put it. So will have to look and get back to you.

Light weight alum. tubing various sizes can be had in wind chime kits for a buck ninety eight in the crafts dept. also, but soldering can be done it may be difficult unless you practice on pop, Soda cans...

Thank you gentlemen!

The salt shaker was a great idea and I found an endless supply of them at a local dollar store. For $2 I bought a simple salt shaker that is 4" x 7" and tubular in shape. It has a bunch of small holes in the top which I will plug with JB Weld. I was concerned about the material but I was able to successfully braze weld the top of the shaker so I will work on the stacks next which I plan to use copper tubing for.

Great, buy two and with carefull cutting they can be fitted together then use the tops for baffles.

Open about 3 or 4 of those small holes to about 3/16 in. and braze em inside the shakers spaced about in thirds of the length..course you'll have to grind or cut them down to a force fit to be able to get em inside the shaker muffler. Size the outlet to no more than the inlet size. If you need a bit of back pressure you may want to go just a bit smaller in dia. on the outlet stack.

If you hard fasten the shaker muffler to the engine then you will need to support the shaker muffler at a couple of places.. other-wise the weld or the stainless will crack from vibration.

Good Luck, My Stainless Shaker Muffler is working great on my Zenogh G-62 Powered Pitts S2-a
Have a gain of 150 rpm over the stock muffler, course I added a 2 in. carb intake tube also.

Let us know how it works out for you.

Aerosol containers are by far the best way to go. Easily weldable and very strong, can be purchased in a large variety of diameters and wall thicknesses / lengths. They can be acquired in rolled steel and even in some cases, aluminum. Mig welding works great for either...

I use "gunk" cans for large cannisters, and WD-40 for smaller ones. Since I use a lot of this stuff on my antique motorcycles, I always have empty cans laying around...

DP, how do you prepare an aerosol can for use as a muffler?

Is there not still pressure in the can even though the fluid is gone?

How do you remove and seal the spraying side?

How can I tell if a can is braze weldable?

Thanks

Norman
