New title ?? might be time with the new stuff, and you might get a few more different opinions and ideas in the process. For the less than $500 you paid for the new stuff, if you salvage just one of them, and are able press it back into service, you are way ahead $ wise. Way back when I bought my mill and lathe, the DRO for the mill cost 3 times more than what you paid for those last 3 machines. Sounds like in your operation, it's about keeping the machines running longer that make your living, in the end it will show in your bottom line. Having some fun along the way, making your business successful is always worth doing as well. It will be fun seeing pics of your new stuff.
