xak1 Posted April 29, 2008 Posted April 29, 2008 I had a loose rivnut (without realising it). Over time it enlarged the hole in the frame, and when I eventually got to the problem and tried to put it back, it dropped into the downtube - the downtube is closed on both sides. It rattles when I am riding. Ideally I would like to get it out, otherwise I will have to squirt some glue in there. Any ideas or self-designed tools on how to extract it again through the small hole?
Mudsimus Posted April 30, 2008 Posted April 30, 2008 Are you sure the down tube is closed on both sides? I've never seen that before. Normally you remove the BB and shake it out.
Veloce Posted April 30, 2008 Posted April 30, 2008 Try one of those telescopic magnets. It looks like a car aerial but has a magnet on the end.
madmarc Posted April 30, 2008 Posted April 30, 2008 remove your BB there is always a hole from the inside of the BB tube into the downtube
Azonic Posted April 30, 2008 Posted April 30, 2008 I'd agree with Mud Dee, tubes always have holes in otherwise welding wouldn't be possible with heat and pressure building up, but lets say that it is closed. Turn the frame upside down with the hole pointing down....... and shake it like a Polaroid picture!
madmarc Posted April 30, 2008 Posted April 30, 2008 What the hell is a "Rivinut"????? a widgetthingymajiggy that will fall into your frame if you don'e keep it tight

xak1 Posted April 30, 2008 Author Posted April 30, 2008 Thanks for some of the suggestions. Unfortunately the rivnut is aluminum, therefore not able to use a magnet. Otherwise, the hole is very small, so you will not get it out by shaking. Will have to design some sort of thing to loop it around rivnut when you get it close to the hole. The frame is carbon, therefore the BB is closed - my LBS say that loose rivnuts on carbon frames happen fairly frequently, so one will have to look out for them.
Azonic Posted April 30, 2008 Posted April 30, 2008 Try get it to roll over the hole, get as much superglue on it as you can then turn the bike over and have it roll down to the BB. Hopefully it sits there forever. Those things weigh nothing, I've had a few replaced before.
