I've cut some pretty thick tube (not FG) with a dremel and a cut off wheel like the suggestion...it took a steady hand and care, and time. The cut was ragged before it was all done..but I was doing "thru the wall" so the attachment to the MMT was the real strong point and glassing over and filleting the fin slot anyway...so the rough uneven cut wasn't as big a deal to me.I didn't know at the time I ordered the body tubes what I wanted in the way of fin slots. Not going to send it back now...
This is the method we suggest for our MPR kits, with one difference. STack cutting wheels together to reach the width the fin slot is supposed to be. With a steady hand simply move the stack of blades cutting along the alignment line. Do it right and you only have to make one cut per fin slot.I've cut some pretty thick tube (not FG) with a dremel and a cut off wheel like the suggestion...it took a steady hand and care, and time.

I've seen that mentioned elsewhere, as well. Seems like a good method. I've not tried it, myself.This is the method we suggest for our MPR kits, with one difference.

Oh, and it's probably best not to let a Llama handle the Dremel....
