Cutting Hole In Tank

[smokemjoe]

I got the bottom part of a 3AA-2400 weld tank that I made a B.Ball Mortar out of. I want to make another one now and put the powder chamber in the tube. I want to cut a 6 in. hole in the bottom for the chamber, How can I do it, Dont have a lathe that big. I layed it out for a 6 in. circle and drilled 4 holes but it 3/4 in. thick and thats not going to work, Thanks for the help, Joe

Do you know of a small shop (metal working) that has a horizontal bandsaw?

  I am back working in a in a pattern- machine shop, They have a Horz. saw that I cut the  1st. part of the tank off.  Did you find powder place in Mineral Ill. okey. Joe

I was goint to hit it for powder, but with rain the third day my travels were shifted a dozen hours and it didn't work out.  Maybe next time.  I appreciate the resource.

A sketch of what you're trying to do will help.
