First of all I know a little bit about bore swabs, the softer it is the more grit it tends to incorporate. Lead is tough and iron is hard, put grit between then and which one gets eroded? So what cleaning rod material makes a flute sound best?
I really want to see how long it takes before someone takes this question seriously.
Set the old drill to high and cleans it out faster than anything. I guarantee your wooden flute will sound bigger after such a cleaning…it’s amazing the amount of sawdust that accumlates in the bore from rough session playing.
On the risk of being accused of being too serious, I have been happy with using flute flags: http://home.nethere.net/roger45/fluteflaga.htm. They’re not cheap, but make for a quick and easy swab out when the flute starts to get loaded up without having to diassemble. I believe he uses some kind of microfiber cloth (ultrasuede?) for the swab material, and graphite rod for the shaft. After about a year of use I had to sew mine up to keep the sides together (he uses some kind of double sided stickey tape that didn’t alst for me), but otherwise I’ve been quite pleased with the tool.
For the HJ: The exact same thing as the flute flag can be accomplished by using a 1/2" wide stick, about 1/8" thick and as long as you’d like it, wrapped in a piece of paper towel. Change the paper towel when it gets too grungy.
For the body use a piece of silk, lightly oiled, at the end of a long piece of string. At the other end is a weight. I drop the weight through the bore and pull the cloth through. The idea is not to dry it thoroughly (so don’t use cotton) but to prevent - and to break up - any large drops sitting in the bore.
Been doing it for over twenty years now. And the price is right.
