    Post Dented dust cap tip!

    I stumbled on this over at youtube and what do you know. That is neat trick. I'd would have guessed it, use a piece of sticky tape.

    One word: vacuum!

    That is one thing I wouldn’t use because you have no control over the sucking. Use a bog roll on the dent dust cap and start sucking on it. Just don’t let the wife see you doing this, she might get the wrong idea?

    I like the idea of sticky tape I wouldn’t have thought of that before.

    I did, but decided having to push more on a dented cap to make the tape stick had potential for making things worse. You control the vacuum by proximity or attach a tube over the hose and regulate it by size. If you're really enterprising you can punch holes in the tube along the side and regulate the suction by playing the holes like a flute. Slightly wetting the dust cap before apply suction really helps make a perfect repair, in my experience.

    I agree on regulating the sucking force. Even placing the tip of your thumb over the tube can reduce the amount of width area that it sucks on. I mean you don’t want to rip the dust cap off.

    Nice trick, not so handy with aluminum dust caps

    I've done it both ways. Tape or vac.

    The wife's Eureka has a vacuum suction regulator to adjust the amt of pull right on the handle. I saved some CTS tweeters used on some Altec Mod. 5 bookshelf speakers using that little sucker.
