My father built a rock crusher

So here is a little video about a rock crusher that my father built . It took him about 6 months to get it to running as it should . We got it from Norway , as it was someone's unfinished project. The jaw crusher part is Svedala 5032F , maybe from the 1960s .And engine is Perkins A4.236 . Engine was stuck , there was water on pistons and rust everywhere , so first thing was to get the engine running .In the video you can see the build will change over time cause not every variation worked as he wanted , so the end result got much simpler . And it is not 100% ready , it can be improved , but for now it gets the job done . Thank you for watching.
