Bushing Made of Brass Tip on Cartridge Fuse
In order to fasten a short piece of tubing in a socket which had become worn to a funnel shape, without having to tap the socket and put in a threaded bushing, it was fixed as follows: One of the brass tips on a spent cartridge fuse was cut off and one of its ends filed tapering. After trimming the fiber lining so that it would fit snugly over the tube, it was driven home. The combination of brass and fiber adjusted itself nicely to the shape of the worn socket and made a tight fit.
