I have a Vogel 1112 1-1/4"-sch40 tube notcher, it has been sitting for a while now. Typical surface rust and shop dust. The dies are in great shape from what I can tell. I don't use tube notchers like this, I was thinking of selling it. Is it worth rebuilding (grinding, lapping, cleaning, etc) and selling or just list it like it is and taking chances? I really don't know that much about these types of notchers, I have always used endmills and fed the tube in to get my angle. Any opinions or suggestions?
