Unboxing plato Sanou 4 garras independientes + comparativa

I bought a new chuck for my Chinese lathe, a Sanou with four independent jaws, and I've included an unboxing video so you can see how it comes from the factory. I've also compared it to the original three-jaw chuck, in case you're thinking of buying one for your machines. https://oxidopedia.greatdevil.net   / laoxidopedia
