How do you take off the black rims on tanks?

thanks for the advice!
I will keep all of these in mind.

I de-rimmed a 140 gal Oceanic to make it easier to trim out in an in-wall installation. A Sawzall did the job quickly and easily with no scratches.

I just picked up a new 10g tank to try this out on, and the rim came off beautifully. So far, so good.

did anybody have an experience of having their derimmed 10 gallon tank break?

I do remember reading about someone breaking their tank while removing the rim. I think they blamed it on trying to go too quickly and putting too much torque on it.

I did realize after I de-rimmed, that my glass hood would no longer fit. So on my nice rimless tank, I now have a standard black lid, which half defeats the purpose. I would have just gone lidless, but it's on a piece of furniture which has a shelf just inches above it, and the moisture/humidity is far too much for that.
