Hi by rifflers do you mean the small s shaped bent files? I have them,they are pretty fine for files and would take a while to do any amount of cutting. I tend to use them more for cleaning up sharp port edges. I've been thinking about cutting some small pieces off of my courser files and welding a angled handle on it. I also thought about buying a 90 degree adaptor for a dremel. They sell for about 35.00, they are small and would fit in a moped cylinder. I don't want to put too much into the tool, then I might as well buy a kit instead. Yes I didn't know if I could bring a stock cylinder out very big. That was one reason I was looking for advice. Thanks Tim
