  1. -Set of wood-boring gimlets (2 thru 5 mm & countersink) - for dad (two handles complete – still R&D’ing the cutting bits)

    -Poker (complete) and stand – first two items for fire tool set – for mom

    -Finish pic frame which was an October birthday present – for wife

    -RR spike hand cultivator to match trowel & weeder – for wife

    Non-smithing – finish bookshelf (paint) – for wife

    And she asked me last night “what are you making for the grandmas, aunts, and uncles?!!!”

  2. Looking at a copy of a 1908 Sears catalogue last night – they sold various forging equipment – they warned of drawing the temper from a steel anvil face by laying a hot piece of steel on it. Made me wonder if a lot of the old wrought & steeled anvils may be softer now than when they were new because of years of heating from all the hot steel in contact. OTOH, you would have to be working some big pieces to actually get something that massive up to tempering heat, and you would see the face change color!

    Sorry for the hijack.

  3. Thanks for the info. this is a wrapped tommahawk head in which the forge weld keeps opening back up at the eye. I think that the forge weld never really took well to begin with, and I've tried to re-weld it w/ the forge so many times now that I'm running thin on material.
    I will try the O/A flame on a test piece first to get the feel of it, and weld away!

  4. The firepot should be about 4" deep FOR COAL, deeper for Charcoal. If that's the depth of the inside of the brake drum, that's great. But it would probably be nice to have the flat table surface flush with the TOP edge of the brake drum.

    If you need to make it deeper, you can bend a piece of flat bar into a ring that sits around the top edge. Again, I think the table should be close to the top - of the flat bar, in this case.

    The drum has to hang, or be supported underneath.


    But these are just improvements; suggestions. What you have looks very serviceable.

    I have changes I would like to make to mine, but I also have projects I want to do, so I just keep putting them off, and my plans continue to evolve.

  5. A lot of thin-walled tube forming is done over MANDRELS. Bending is done over a flexible BALL Mandrel. (That's how they did it for Motorcycle exhaust when I worked there). I suspect the twisted forms are done by this machine similar to what NeatGuy is doing with his Nibbler, but maybe with rollers. Since the machine exerts consistent pressure across the pipe, distortion and collapse is reduced. During my last year @ the scooter plant, HYDROFORMED pipe was starting to come into use.

    A collapsed twist is not always bad. Check out Decorative & Sculptural Ironwork by Dona Z. Meilach.

    Here’s a TP holder I made from 1" od pipe. The 180 deg. turn on the right was twisted AFTER the pipe was slightly flattened to encourage collapse.

  6. Jack Andrews, in The New Edge of the Anvil said that when he worked over a dirt floor, he would sweep the floor smooth in the morning, and by the end of the day he would have created a motion study of footprints in the loose dirt. He includes a diagram of tool usage based on this data; page 9. This will vary with the type of work you are doing. I suppose if you have a hard floor and are not too anal, you could sprinkle dust over it and work over that.

  7. I dont think powder coating would hold up as well as plating - I hear once the plastic surface is knicked and moisture gets in, it quickly spreads corrosion underneath.

    Of course, plating could have similar problems, just take longer to manifest.

    If you had a buyer willing to pay the cost for plating, it would be worth it; but not for your private collection.


    AWSOME WORK, anyhow!

  8. I got a beautiful "hand cultivator" as a trade item this summer. The working end is split into six tines and the handle flattened, among other stylish features. Much to nice to use. The piece won the "Iron Master" vote for the day; the PABA Kutztown Blacksmith Days. Made by a Mr. Sutton. I will add a pic if time permits.
