Setting a wagon tire

How about one of these.

They're probably concerned about sparks flying, catching the rest of the state on fire.

You need to get the whole tire to about the same heat to get the stretch you need. How about using a DC welder, as they do to thaw pipes? That oughta work. They used to use a pine stick to test for the right temp. When the pine stick smokes and feels like it is "slippery" when pushed along the tire when it is touched to the tire, it is hot enough. I think that's about 700° F or so. You will need at least 4 supports under the wheel for the tire to stop at. More is better. Be ready with at least one helper. And have

I have only assisted in one session doing this to 4 wheels for a circus Hippopotamus wagon, but that's what I remember.

How hot does it have to be?

The coefficient of thermal expansion for steel is 0.00000645in/in/deg F.

So, how much fit do you need?

If you heat it up, and then slide it onto the wooden wheel. Won't that char the wheel some?

Six guys with six torches? When I was more actively doing HVAC. The boss and I would chit chat while we used two torches and two rolls of solder to assemble 1 1/4 copper pipe for boiler heat systems.

Well, it ain't much, really. If you heated it up 500F, you'd get a 1/4" (roughly) circumferential expansion, which would be 1/4 over pi inches in diameter, or roughly a bit more than 1/16" diametral expansion.

That's enough, I'd say, to get it over a well-sized wheel. If not - if you wanted to pull the wheel together tighter than you built it - heat it up 1000F for an 1/8" increase.

On a wooden wheel, what you really need to do is make sure it will shrink down further than the amount it burns away the wood before it's below

You've got 27" to work with if you put it in diagonally. There's a third dimension to be concerned about, but it's faster to try it than to work on all the calculations.

It doesn't matter if your oven tops out before the wheel has expanded enough, though. (But you knew this.)

It does, indeed. The "art" is in having it char away less wood than the amount it will shrink after cooling. There are ways.

In the time it has taken to discuss this, I would have dug a shallow hole, filled it with charcoal and done it. This is a classic case of overcomplicating things.

Not an option. If it was I would already have done it.

I'm with you on the ring. Should be real if possible.

How about a ring of charcoal brickets like used for the Bar-B-Que fires. Maybe a small hill in the center of the main ring circle.

lay out the ring on the ground - make a row inside and outside - then crunch them together, run a line of fire starter if you don't use auto-start ones.

So no real fire, just some bricks - and you can hose them down after wards.

How do you figure? If I tilt it up front to back then I've only got the

Looking at this further, I may need a bigger tank than I'd want to handle to get this whole thing to red heat with oxyacetylene. Mongo weed burner is looking like the right tool.

Have the womenfolk stand by with grilles and steaks once you move that damned tire out of the way of their cookout. ;)

Hmm, I don't think that'd do it.

Yeah, make sure you quench quickly so it gets -brittle-, Arty.

The majority of the smoke is from when the tire cools onto the wheel and the wood burns a bit, but it's air cooled, not water.
