Sweet!

So it turns out trying to make a flat piece of steel into a perfect circle isn't very easy. It took me an hour but I got it pretty damn perfect. Still trying to decide how to weld it, I can tig it no problem but worried about warping it. I would really like to rig up something to turn the wheel super slow and just mig it without any stops and starts. I will figure something out :)

Miggin it will warp it too.. I don't know if you will be able to do it all in one pass.

EDIT: Also, building a roatating welding assy isn't too bad, seen a bunch on the welding forums I frequent.

won't tig introduce much less heat into the base material?

Karl Buchka 08-03-2012 10:25 AM

Not necessarily.

55superbeetle 08-10-2012 02:42 AM

Got one done and it came out pretty damn good. I tig welded the inside and migged the outside. Ended up with .020 runout and less than an ounce of balance weight. It fits the car perfectly, now I just have to do another one....

Tire is a 255/45/17 and the rim ended up 8 1/4 wide

Sweet! You said you took a flat piece of steel and banded it yourself right? Did you bend it first then weld it on or did you bend, weld, bend, weld? Do you have any pics of the finished wheel pre-tire? Awesome work?

How much does it weigh?

Kaelwaggin 08-11-2012 02:51 AM

Car looks suuuupper clean. Well done!

I'm still sad I never got to roll in the oval....

Here are some more detailed pics,

Here is the band I rolled, I did it on a tiny slip roll made for sheet metal.

Tacked it together and put it on my friends tire machine to check runout.

Welded on the outside, going to weld the inside tomorrow. I welded it in 3-4 inch strips to try to keep the heat spread around. I also decided to tig this whole wheel, just comes out cleaner.

I don't know what it weighs but I will try to find a scale before I put the tire on.

You didn't miss anything, the volvo is just as fast and doesn't break :)

M.H. Yount 08-14-2012 07:27 AM

Weigh it with the tire mounted. And it probably won't be near as accurate with a bathroom scale unless you use yourself as the 'holder' - then subtract your weight.

Glad you decided to tig it.

It looks great!

This thread makes me want to buy stock in rubber.

55superbeetle 08-15-2012 11:50 PM

Bare wheel ended up weighing 26 lbs, tire weighs 26, making a grand total of 52 pounds. Heavy I know but they get the job done.

M.H. Yount 08-16-2012 07:29 AM

Actually, if your weight is correct, it's incredibly light for a steel wheel. This aluminum wheel from our friends at IPD - http://www.ipdusa.com/products/4909/...h-hyper-silver - also weighs 26 lbs. And I just sold a set of 16x7 Mille Miglias with 245/45/16" Michelin's on them -- and they weighed 49.5 lbs. as a combo. All of which leads me to think your scales might be off a bit....

The Full Banana 08-16-2012 10:38 AM

Not that crazy, my 17x7 BMW steel wheels are less than 20lbs each.

55superbeetle 08-16-2012 12:34 PM

I used our electronic shipping scale at my work, I don't think it's that inaccurate.

WillettRun? 08-16-2012 12:36 PM

hehe.

M.H. Yount 08-16-2012 02:25 PM

Well - it's a mystery of life I suppose. Aluminum (at 1/3 the weight of steel) and steel wheels that weigh the same.

There's really no mystery to it. Aluminum may be 1/3 the weight, but it's also got to be at least 3 times as thick to get the same strength out of it. When you compare steel wheels (.060" thick) to a typical cast aluminum wheel (.25" thick or more) it's really no surprise that steel wheels can end up pretty light.

Now, when you start talking about forged wheels, that's an entirely different story. But most aftermarket cast aluminum wheels are not nearly as light as you may think they are, including those 26 pound wheels from IPD.

Anyone who's picked up a Virgo knows that aluminum wheels can be real boat anchors. On the opposite side of the spectrum, the 18x13 3-piece BBS wheels for my 242 are 24lbs a piece.

That's not how materials behave. There is not a linear relationship between the material thickness and the deflection slope. The moment of inertial comes into play. I = b*(h^3)/12 I = moment of inertia, b = base, h = height. In the case of the wheel, h = wheel thickness. So, based on that relationship, it would require the aluminum to be ~ 1.44 times as thick as the steel to be the same strength in deflection. That's why you have aluminum, magnesium, titanium etc used everywhere in designs requiring minimum weight as a requirement. No matter how you slice it, aluminum wheels of the same weight are going to be stiffer/stronger than steel wheels. It's the cost that comes into play. Steel is very uniform in its properties. The many ways aluminum can be used makes the end products properties vary greatly. Spun aluminum wheels are incredibly strong and ductile. Cast aluminum wheels are rigid, yet, brittle.
