Yeah, I can see that. I have never used the stuff so it is foreign to me. I
can see the cut off material getting embedded. As to localized heating man I
don't see how that could come anywhere close to what either a torch or tig
does. In any case, I am not likely to ever runa ccross chrome moly tube in
anything I do so it is definitely moot to me. If you cannot use a cut off
chop saw then how do you grind on it? Maybe I am not supposed to. I use a
sears reciprocating saw for all my cuts and the tubing notcher. Defineitely
moot. I learn more neat stuff on this list.
