This tool restoration was on a Russian / USSR chain mortiser. I think it was made in 1973 by Electricgalvanic and has the model number IE-5601A. I do not know much else about this tool as most websites (which are in Russian) do not go into much detail. I believe the chain came in three different widths, and I have the 3/4" one. If you know more about this company or tool, please let us know in the comments. The restoration itself was pretty straight forward as only a few pieces were missing. I decided to paint the tool as some of the photos of this tool online show it painted and the person I was restoring this for asked for it. In this first part, I disassemble, clean, and paint the chain mortiser. In part two I reassemble, make new parts, and get it running. This thing is a beast!
