hi folks,
don't know if this wee idea is new to you, or indeed any good, but Nige's question about pencil sharpeners reminded me of something I came up with to roughen the brass tubes. Having quite a lot to do I put a medium grit carborundum burr in a Dremel type tool and holding the brass tube at one end at a time I run the slowly revolving stone against the tube starting about halfway, well a bit nearer my fingers in fact, by using a fairly rapid action, exactly like sharpening a pencil and turning the tube between my fingers, the tube is very efficiently roughened. It works (perhaps you all do that, or better!)
