  1.     I would take it to a machine shop, have the box bored out and the male thread turned off the screw. Then wrap the screw with a doubled over piece of stock large enough to to create a diameter equal to the ID of the box. Snip the wrap where it is doubled over and unscrew one spiral from the other. Then braze one in the box and the other over the the tenon to recreate the mail thread.

     

        Be warned the machining may well cost more than the vise is really worth!

  2.    Incredible what they managed to do so many years ago. Forging, Machining, Casting and all that fun.

     

     

      Good godfrey man ,don't talk about it as if it were men from ancient times! That film was made only 15 years before I was born! Those engines were built at what could now be called the height of mechanical engineering. The same period as the British Spitfire, the American P51 Mustang with the Marlin and Allison engines respectively.

      

      It was a time of great skilled craftsmanship both in engineering design and skilled workman who still new how to use their hands.Not a time of cave men with limited resources or experience.

     

    RANT over you just made me feel old all of a sudden, somthing I don't really notice most of the time :unsure:

  3.  Dave ,

    When you buy bronze you are often offered it in "hard, half hard or annealed". If your concern is the strength for say towel bars I would buy either the hard or half hard dependent upon length. That is if you only plan on forging the ends and leaving the rest as is. you could also finish forging cold to work harden and increase it's resistance to bending.

     

    As for copper I'm not familiar with buying it in different tempers but suppose it may be offered that way. The issue with simply going larger on either material is that IE: would 1/2" round annealed be better than 3/8" round hard.

     

    Hope this strange explanation helps.

  4. Sure a rotor will work. It might even work better than some brake drums as many newer drums are only cast iron on the perimeter with rest being stamped steel.

     

    Try to get as deep a rotor as possible or gain more depth by building up the top with fire brick. 

  5. I think your formula is wrong:

     

    The length of your lever is 20" not 3.14 of a 20" radius.

     

    I don't know the proper calculation but logic would dictate that it should be more like ( pounds of force ) / (Pi x dia of screw x TPI ) or something like that and of course the subtraction of some sort of energy coefficient plus you'd have to consider the speed of ram travel also.

     

    I'm not trying to be a PITA but just pointing out that your formula seems WAY to simple. 

  6. If you choose to use the rubber, my advice would be to epoxy your anchors in or use springs on top of the hammer base and under the anchor nuts.

     

    I once used rubber under my hammer and nutted down directly against the hammer base. The compression and expansion of the rubber under the hammer while running kept jacking the anchors out or loose from the concrete! 

  7. That anvil not only looks crooked it is crooked  :mellow:  I have two colonials and they are forged crooked also. It's my belief that they were forged this way so they would stay on the stump when working with strikers. Since these anvils have little or no feet to help tie them down the angled face when being struck from the "off side" by strikers heavy blows tends to drive the base of the anvil down into the stump rather than askew and of onto the floor.

  8. there are no bolts on wooden wagon wheels. the rim holds it all together

    Beg to differ........many tires were held on with bolts on light buggies in the later part of the 19th century. Check out M.T.Richardson for some references.
