Dremel cutoff wheel. That would work nicely. I used a hacksaw. I find I can mess things up pretty quickly using power tools, course I can mess up pretty quickly not using power tools too.
The Tisas looks great.

A detective from my old PD bought one of those Challis bushing tools I'm too cheap to buy. Said he used it once, didn't need it any more and felt I'd use it more than him so he's gonna give it to me. So now I guess I only have to buy the slim bushing tool and I'll have both. Life is good.
