Thread: Old Machines

    Old Machines

    On occasion I have to do some repairs to plastic injection and diecast molds. Usually when an ejector pin gets snapped off. Some of my molds are from the ealrly 60's. When I have to do repairs to those I break out the tig welder, and Pantograph templates. Don't think many shops anymore use these.



    We actually have six that are in pristine condition. Although 4 of them are covered in cosmoline and in storage. I know there are a few machinist on here, thought you would get a kick out of it.

    We have an engineer at our shop that has been a hobbiest knife maker for many years. He has like 3 of thes set up for different ratios and template plates. He swears by them.

    We actually took the spindle out of one and retro-fitted to one of our Wells Index CNC mills (knee mill). Those little spindles can handle high rps and hold amazingly tight tolerances.

    old iron is best iron.

    i used to work in a shop that made parts down to 2 or 3 millionths, using a jig grinder from an old WW2 destoryer as its base. that old hand scraped ways iron is good stuff, and if its been taken care of, it never goes bad.
