Cutting a cylinder square

[Paco]

I have this cylinder/tank (bellow) and I would like to cut the top and bottom off. Although I'd prefer to use tool I may have, I'm open to other external/sub-contract solutions.

It would easy to cut it with a cut-off wheel on a grinder but I'm looking for straight and square cut.

Thanks in advance for any help.

The ends appear to be square. Just measure back from each end where you want your cut and mark every 3" around the circumference and then free hand in between the marks. Appears to be stainless so lay in a good supply of cutoff wheels.

Use a pipe wrap to mark a layout line. If it has a straight edge to it and is wraped flat against the circumference, then the edge will be square to it. Cash register receipt tape works well for this purpose in the absence of an actual pipe wrap. Manila file folders also work well and have the advantage of having a decent thickness that is better for drawing lines, but it looks like they will not be long enough for you.

Mark it like that, then carefully cut using a cutoff wheel. Cut a little longer and you can always trim it back.

ummm...a good bandsaw...as long as the bandsaw is true and square, clamp the pipe into it and let it do it's thing.

cutting disc.. 1/16".... Pferred makes 'em for stainless which would be the best.. less heat, less clean-up..

A length of emery cloth will work also.

find a cutting house or fab shop with a horizontal drop band saw, or drop cold saw and they'll have it done in a few minutes, square. Also if you have a access to a lathe or rotary fixture you can spin the part and cut it off with a fixed plasma torch. that can produce very square parts as the part is never touched.

Static-XJ, thanks! I like that idea a lot.

mla2ofus, that could work but the bottom and top are weld very rough...

Thanks all for help!
