It was in spring this year when I picked up this beaten up antique hand cranked hammer drill. My friend has found it on the steel waste together with the german „Weltrekord“ ratchet screwdriver. The condition of the drill was super bad. It was very corroded, had a lot of missing screws, the handle was in very bad condition and the crank was bent so much you couldn't even make a full turn. That's all said, it was the perfect item for a new restoration video.
At first I thought this should be a quick and easy project, but one problem after the other became visible and it turned out to be a real challenge. There was the big dent in the left side of the case. Usually you can't bend casted parts, but with a bit of heat and careful pressure on the arbor press I was able to remove it a bit. It also worked to get rid of the warping with some heat. For the finish of the housing I wanted to have an antique cast aluminium look. I thought it would look very cool if I could tumbler these parts after sandblasting. I ended…
