  1. I believe Jim is right, at the machine shop where I did my apprenticeship we had a
    machine that utilized grinding wheels just like that and mounted the same way.
    We used it, mainly because we did work for the local Caterpillar dealer, to resurface
    cylinder heads.
    As far as using it on a machine without knowing what type of abuse it was subjected
    to.........don't think I would do it.

  2. Nice work, keep us updated.

    I work with metal and deal with metal suppliers on a daily basis and keep very
    close watch on material prices, even at my cost H13 is outrageous. It is a good choice
    for your given application, the chromium and molybdenum content gives it excellent
    abrasion resistance and hot work capabilities.
    After doing some research ( I know I'm opening up a can of worms here, LOL) full
    rockwell hardness of 23-28 on H13 cannot be achieved unless perfect conditions are met and one has the proper equipment to do so.
    On the other hand 4142 might be a good alternative cost wise and the fact that full rockwell
    hardness of 27 can be achieved by raising both materials to 1200 degrees. The cool down
    soak and reheat on H13 is where it gets a little tricky.
    Yes, with the 4142 material there may be a downside as to not having the "abrasion resistance " but let me say this,when I machine this material if you do not keep some
    type of flood coolant going it will "work harden". When this happens a file won't even
    touch it and you think you're dealing with H13.
    So basically what I'm saying is, for the light user there are alternatives. Check out
    John Crouchet's website (Texas wrought iron) see what he makes his tooling for his
    fly presses out of.
    Food for thought and my .02

  3. Nothing better than seeing the old iron!!

    Like previously mentioned, it is a horizontal milling machine and yes they are
    "old" technology. With a little elbow grease and tlc that would be a handy little
    machine to have around.
    The cutters do resemble saw blades but come in all different sizes, shapes and angles.
    That machine more than likely has a 7/8" or 1" arbor size for the cutters and they are
    still very much readily available from new to used.
    A word of caution, they will hurt you, machine tools demand respect and do not have
    a conscious !
    I have a very large horizontal mill that I operate allmost on a daily basis and that ole gal
    and I have a very clear understanding of whos the boss.
    Given the design of the machine in your pics I would say it most likely predates WW2.

    Keep us updated if you move forward with it.

  4. Parallel would probably be the more ideal setup, in a series you would have low pressure at
    the second cylinder and more than likely they wouldn't stay in "time" with one another.
    One hose to an adjustable manifold, split from there to each cylinder.

    Hope this helps.

  5. I am by no means an HVAC tech but IMHO I do not think this would be a very effective/efficient
    method of transferring warm air.
    Maybe if the pipe had some sort of insulation wrap? What about ceiling/floor vents to let the heat rise?

  6. Been a lurker on the site for a little while and the wealth of knowledge and experience, as well as the talent that is portrayed is truly amazing.
    Although I am not a blacksmith, I do work with a wide range of metals very extensively on a
    daily basis ,I'm a one man machine shop and the blacksmithing side of metalworking has grabbed my attention.
    Looking forward to learning ,sharing and problem solving with others.................
