  1. Tom, depending on the wood you might want to consider placing bitumen between the anvil and the wood.

    Some trees, oak particular, contain aggressive acids. The bottom paint will very likely wear off and expose the metal to acid.

    I had a hammer laying on a fresh oak over night, the next day it looked like it has been a month in the rain

    A cold anvil will draw the heat out of the working peace, don´t use a sledge while its too cold and warm the anvil up with smaller work first 

  2. I tried to get a tour of that forging operation in Berkley....no dice. I'd like to though.

     

    I heard a rumor of a much larger press in Russia....

     

    Russia had the world largest press with 75.000 Tons until the Chinese build this one.

    A large die-hydraulic press forge is one of the key instruments in making jumbo planes.

    The current largest press forge is 75,000-tons and is owned by Russia. All the press forges currently in China are below 40,000 tons, which are unfit for making key parts of very large planes and hence hinder the development of the aviation industry, equipment and manufacturing.

     

    To prepare for the very large plane project, China began building its own regional jet, the ARJ-21 -- meaning "advanced regional jet for the 21st century" -- in 2002.

    Only the United States, Russia, France, Germany, Britain and Spain currently have the ability to build very large aircraft, with the United State's Boeing and Europe's Airbus taking the lion's share of the international market.

    And KRS: 

    You are a big "Glückvogel"! What a find! I hope you can use that in health for a long-long time!

     

    Bests to you Guys, happy digging!

    Indeed, I could not believe it myself- it was well over a week at the scrap yard and nobody could tell me how much it is, the boss was away then.

    After she came back I was told to put the shear on the scale, was asked to pay the scrap price (for 230kg with the stand), payed a bit less and put it on the trunk :D

  4. One mans hole is another mens bending jig

    Salvaged from the scrap yard, it was greased and then painted all over by the previous owner.

    I don´t like the color but otherwise its perfect.  :P

    One wheel is out of track, but as long as I don´t take it to a race its ok

    Manufacture specs are:

    Peddinghaus 13 RP 10 (was hidden under the paint)

    Round 22 mm
    Square 20 mm
    L 60 x 60 x 7 mm
    Flat 90 x 14 mm
    ca. 180 kg

  5. There are square holes on its sides and on the bottom. What are they for?

     

    Jock Dempsey wrote something that I didn't knew for a long time, there was a forth hole in most(?) forged anvils:

     

     

     

    The body block starts as a simple rectangle with 4 handling holes (-). The handling hole in the top is plugged in the last step before welding on the hard steel face.
  6. Any melting fuses in the cutter?

    Next I would look for damaged capacitors, bottom right in your second picture. If the top is warped they are very likely damaged but easy to replace.

    Look for any signs of a arc or heat damage, the transistors on the aluminum plate look good as far as the picture goes but they tend to burn out quickly if overheated.

    A burned coil can be harder to spot because a shortcut can happen inside the windings.

    Good luck 

  7. I have a pedal switch on my drill press but nothing else in the shop.  My only concern about a foot switch on the power hammer would be an unplanned motor start from tripping over it accidentally. 

     

    And everyone's habits differ, but I usually turn on my hammer and leave the motor running until I'm done forging - whether between heat cycles or not.

     

    A foot switch like the one on power shears should do the trick
