A leatherworking tool the collectors seem to value is the heavy rawhide mallet. If a leatherworker wants, or needs one of these you have to settle for one in poor condition. The renewal of one is actually quite easy once you have it apart. Once apart, and old rings removed (small wooden wedges will help) ,I derust the iron parts, prime them, and repaint. The next step is to make the many rawhide rings, making them slightly larger than the size you want. Assemble the new ring, and leave it to set for a few days, and compress, then retighten. Unless you are lucky, a new handle will be needed as getting the old wedge out will usually ruin the old one. Here are photographs of ready to reassemble, and finished. After the mallet is reassembled, and compressed size the rawhide by sanding against a disc sander.
