With a die grinder or hacksaw or the teeth of your Alsatian cut off the 1/4-20 and 10-24 sizes Hex drivers from your Hex Keys to make a straight part.
Then the next time you need to remove/replace a woofer or horn chuck one in your cordless and away ya' go! ![](http://home.att.net/~wsepstein/wsb/media/134428/site1274.jpg)
