another solution comes from your kid's bike. i snipped a 1/2" cross section from a popped bicycle inner tube yeilding a fat, steely grey "brocolli band". one inner tube yields way more than you could ever use. i stretched it over my K1 knob and it works well. mike, AK3F K1 #522 ------ Save the twelve bucks. If you eat Broccoli just save one of the wide rubber bands that come on the bunch. <snip>
