  1. Hi oscer, I had a problem with close neighbours and could not have any vibe getting away and so had to isolate the hammer totally. I talked to an anti vibration  engineer and came up with this, which works well and no shock at all is felt outside of the floating concrete inertia block.

    It's a pit in the floor of the workshop with an 8" thick floor all reenforced with steel. Then build a big box to fit in it with a gap all around and 6" shorter than the depth of the pit. the stacks of anti vibe rubber shock absorbers (in my case 20 of ) placed around underneath. Fill the box full of concrete ( 9 tons ) and hey pesto.

    All of the variables were fed to the engineer- how heavy- how hard it hits- how fast it hits- and so on. with this he worked out what density of rubber - how many thicknesses - how many pads and so on.

    Don't know if this is useful but here it is.

    P.S. to get the floor level with the box of concrete was another equation on how much the rubber shocks would take up when the box was filled.

  2. Nice piece of work. Can you post the complete dreamtime story please?

    Thanks Frosty, heres the wording ----BOORUN THE PELICAN CAME DOWN FROM THE NORTH WEST ALONG WIRNWIRNDOOK (THE MACALISTER RIVER). HE CROSSED DARTYOWAN (THE LATROBE RIVER) NEAR THIS SPOT AND MADE HIS CANOE, WHICH HE THEN CARRIED ON HIS HEAD AS HE WALKED TO YOWUNG (PORT ALBERT). AS HE WALKED HE HEARD A STRANGE TAPPING SOUND. WHEN HE GOT TO THE INLET BOORUN PUT DOWN HIS CANOE AND WAS SURPRISED TO FIND A WOMAN INSIDE IT. SHE WAS TUK THE MUSK DUCK. HE WAS VERY HAPPY TO SEE HER AND SHE BECAME HIS WIFE. BOORUN AND TUK ARE THE MOTHER AND FATHER TOTEM OF THE GUNAIKURNAI PEOPLE. 

  3. Just thought I'd put this up. I worked on this with my wife and a group of indigenous australians. It's corten steel on a 316 stainless steel dious which sits on a concrete moulding. The lettering spells out a dreamtime creation story of the local people of the area, in 430 stainless steel.

  4. While it looks cool, those scale cold laps can/will come loose and can cut someone. A quick stroke or two with a wire brush when it comes out of the fire to knock the scale off before it goes on the anvil usually takes care of driving scale into the work piece.

     

    Leaving an as forged or hammer texture, heck any texture, should be a deliberate process rather than just what happens.

    Thanks Frosty, so it looks like scale is what I've been thinking were "cracks" . I think I've had both, but the idea that not cleaning off before drawing out has caused what I thought were delamination ( and was in fact the opposite ). It's true that I was only banging the hot metal on the floor on my way to the hammer to let any loose scale drop off and not brushing it off. Thanks for the heads-up.

  5. Col why does it look like it has been run over by a steam loco?  Are you also putting a textured finish on the steel as well, or is it supposed to be smooth?

    I'm leaving the marks on because the look I'm going for is polished but rough, I have thought about swages and a nice perfect finish but it would just look like someone turned it on a lathe, hand made/distressed look is better I reckon.


  6. Okay, I'm into the next set of torches and not letting the metal get below orange (starting out yellow) and staying nice and square as I go down the taper forgemaster, and I've got it into the round, and NO CRACKS, woohoo. Thanks everyone. I think Frosty had it right about listening to the metal.
    You would'nt believe it, when I polished them , just one out of four had the same hairline cracks/delaminations.
