    Help Round pipe in tank

    How do I make a precision fit of a 3 inch round pipe into a round tank?

    I need a 3 inch round pipe installed in the 24 inch round tank. I Need the pipe to perfectly vertical but it will be offset a bit from straight up on the tank if that makes sense. Instead of being just straight down into the center of the tank it will be offset to one side just bit.

    I almost lost my new welder to the storm here two days ago. Water over the back ditch came up the yard and into my shed. I happened to go out and see my Miller about 1/2" above the water. I managed to get it jacked up. That would have ruined my day.
    Bummer dude
    It would be nice tho if you would go into your user profile and put in your location so maybe we might know what storm you're even talking about, and while yer at it you could put up you signature and that way we could know what welder you have

    If you want to layout, fishmouth a section of 3" cardboard tube or cheap 3" vent pipe and use it to trace over the tank.

    You could even burn the hole smaller and take a Crescent type wrench and flare the hole out for a custom fit.

    Even with some guess work you should be able to come close enough to burn it and have it weldable. It would be a big problem if you were to come up an inch off. Heck its so primitive you could hold the thing up there and burn around it till the pipe went thru the hole.

    Yeah, I was more concerned about making a pattern to cut it out from than how to cut it. I didn't want an egg shaped hole that I had an inch on one side or the other to fill in.

    Thanks guys. I book marked the site. The tank is going to be a smoker. The pipe is the exhaust stack.

    Your welcome. The sheetmetal shop is one of my favorite sites beside this one. They have a lot of reprints of old books from around the turn of the 20th century. I ordered the DVD of old books and its great, I definitely recommend it.
    Here is a link to the site if you want to poke around a little.

    Check out the library, you'll find some interesting reading there.
