Yep, my Grandfather used exhaust from the engine from his welder for many years, until one blew up.
It didn't kill him but he quit relying on that method.

Didn't know that, I guess I could see that if the engine was running rich

Ever seen flame throwers on car exhausts? In a nutshell, they put a spark plug in the tailpipe, hook it to a coil, and when they push the button it re-ignites the un-burnt fuel in the exhaust.

I'd almost bet you today's cars wouldn't do that , all the epa s standards take out nearly all pollution from the leftovers.

Carbon monoxide is an explosive gas. Mixed with the right amounts of air it is combustible. There is no dependance on fuel particles for this to happen.

Learn something every day! I guess we don't see CO burn much because it tends to be generated when there isn't enough oxygen around for complete combustion of fuel.

CO is one of the least listed. If it doesn't burn coming out of a hot exhaust and catalytic converter, I think that is a minor issue.
Modern equipment, especially cars with a normally functioning emission control system, that is up to temp should not put out any significant amount of "rapid burning" gases.

OK guys - I am halfway through (or maybe done - lets see what you all say).
I found a piece of 1/2" stock that fit perfectly. A bit thicker than I wanted. I did a layout with the fishplate template and it looked good with the marker. But, I have a lot to learn with my Plasma Cutter and it was wonky as a mo fo. Need to learn that when you are cutting cornere you have to be straight up and town, an angle of any sort just does damage
At this point I put some Co2 into the oil tank. Ran a bit of gas from my mig into it to help alleviate any heat worries.
So next I drilled a relief hole and then ground down the crack. The first picture is grinding it flat. THe second picture is grinding into the metal. You will notice two drill holes. Thought I had found the end of the crack but when I ground I found I was off a bit. I then hit the whole thing with a torch. Heated the area up, Hopefully burning out all the oil in the crack.
Flat Grinding
Gouging
Before the torch and cleaning
So then I put the Fish Plate down and started welding. I used my Lincoln 180C for this layer of weld. Set the voltage almost all the way and wire feed at 2/3rd. I have found this setting gives me nice penetration but doesn't dump a ton of metal. I welded at 2" at a time per my neigbors instructions. I find this very difficult as I get my mojo going and then when I start again I blow it.
The Weld
The grind after the weld
Fish Plate and Details
So here is my question. Should I do another pass. I am not sure what it gains me but that is because I am an inexperienced welder. On the verticles do I do a strand on either side of the weld tying in the current weld (making the weld wider?) Going to take a lunch break and would love to here your thoughts

It would not hurt to put another right beside it.

I would not have run the plate that way. I would have run a triangular plate across the two corners. A right triangle to bridge both sides together. It's a type of fish plate, but the way the joint is, it doesn't do a lot of good to have a long one that really only reinforces both sides. I don't think you've gained much strength or bend resistance running it that way. I could be wrong though. Don't forget to redo the inside vertical weld. There will be problems there too.
