A few weeks ago I visited my friend and we took a closer look at his barn, looking for something interesting to restore. As soon as I saw this hand cranked grinder, I knew that this would make a nice restoration video. It was all covered in wood dust and the visble steel parts were very rusty. It was still working, but the grinding wheel was very unbalanced. When I was cleaning the parts with the parts washer I found a lot of nails and screws in the gearbox, I guess I was very lucky that I didn’t found any teeth from the gears. The pin connection from one gear was damaged very hard. I filled it all up with welding and machined all surfaces clean again. I decided to make a brass sleeve for the wooden handle and glued it in with epoxy. I only cleaned the grinding wheel with high pressure water and it worked very well. Due to the age of the grinder and the cleaning with the water, the two paper discs were lost. That’s why I printed two new ones with my logo on it and they turned out very nice. They’re there to lower the pressure on the grinding wheel from the clamping. The cover plate from the gearbox didn’t fit at all, it didn’t even cover everything. Because of that I decided to make a new one. For the painting I choose a black coat, as it was originally, I used filler on it to get a nice and smooth finish. I’m very happy how this project turned out, I’ll keep this item for myself for display. I hope you like my work and the video.
