Rusty Deadlocked Vise - Restoration (the 3rd) (2160p_25fps_AV1-128kbit_AAC)

In this video I&restoring a very small rusty and deadlocked Gressel bench vise. Its jaws are just 80mm wide. My friend has found this tiny vise on the steel waste and I thought this would be cool for a video. On first sight it was only seized and had some additional holes. When disassembling I also quickly realized that something on the half round part was not right and after sandblasting I also saw pretty deep damages near the jaws. To disassemble the movable jaw I quickly made a tool to open the vise. There&also a video about that on my second channel „my mechanics insights“, link below. I closed the two additional holes with slight press fit plugs and closed the gap with welding. After filing the welds flush the two holes completely disappeared. There was a bit of a mess with the threads at the half round part, so I decided to close them all with very tight press fitted plugs and cut two new M4 threads. That worked very well and these plugs will never ever come out again. On the other deep damages I decided to weld up new material with cast iron stick welding rod. That was my very first time stick welding. Was a bit tricky to get used to it, but the end result turned out very well. I was able to file and sand all surfaces perfectly clean afterwards. I decided to paint this vise in a nice red (RAL3011) with white highlights on the lettering. As the spindle only had very little rust, I was able to clean it very nicely with rust remover, wire brush, some sandpaper and Scotch...
