  1. Ever wonder why there is not massive blood letting at a knife show? It is not the swoards and knives killing people, it is the people killing people. They been doing it since near the beginning of time.

    Better hide your sticks and rocks, they will be next.

  2. 1. Burns
    When the blacksmith grabs the hot end of the iron.

    2. Galls
    When the blacksmith expects paid for his work.

    3. Internal / external cracking
    The mental health of the blacksmith after a hard week.

    4. Surface defects
    A sweaty shirt, dirty hands, cuts, blisters, 3 day beard,etc

    5. Coldshuts
    This is rare, but asking the bothersome client that can not be pleased, to step outside then shutting the door.

    6. Over / under forging
    Over - taking way too long to complete a project. Under - not taking enough time to finish a project.

    7. Bends
    The muscle pain from too many hours of working slumped over an anvil that is set too low.

    8. Kinks
    See bends.

    9. Poor /open jointing
    Poor - Not being able to attend the hammer-ins (Blacksmith meetings) that you want. Open - Being welcomed with handshakes to the hammer-in outside your state.

    10. Finish quality
    1st, 2nd, or 3rd place in the farriers speed contest making horse shoes.

    11. Lack of accuracy to specifications
    The difference between the plans designed by an engineer using 6 decimals and being built by a blacksmith using a 3# hammer.

  3. Rthibeau, why not just cut a few corners and make the project go faster?

    Make a square bolster block to fit inside the tubing. Drill the holes, insert the bolster into the tube. Make a corner chisel (think wood working corner chisel) and with the bolster for support, just cut a few corners and a round hole becomes a square hole.

  4. make sure you supply a straight bit of string


    Can you suggest a source for "a straight bit of string"? Is it a special brand that is starched something? And how do you transport straight string that is over maybe 3-4 meters in length?

    I ask as most string available here is quite limp and sold in either a ball or coil. :wink:

    what ever you do avoid string that hangs off vertical


    "String that hangs off verticle" - is this labeled as such, or is it some kind of special string, maybe a factory blemish, or factory second that does not meet standards for being straight string? :shock:

    This has me puzzled. I thought the upper attachment point of the string would always be directly above the attachment point to the weight. The weight would then rotate to align the balance of the weight in reference to the point of attachment. In other words if you attached a meter of flat bar to a limp string (the type we are accustom to using) the string being attached at the center point of the end of the flat bar, the opposite end would hang down verticle. If attached to the center point of the length (half meter) the flat bar would hang horizontal, with the string in the same verticle position as before. And it attached between the end and the mid point, the flat bar would hang at an angle,with the string in the same verticle position once more. In all three instances the string should hang from the top attachment point in a verticle direct line down.

    This brings up another question. :idea: If you were to look down the string from the top to the bottom, what would the string point toward - the center of the earth? I am going to guess that a brass plum bob is used so as not to be influenced by the magnetic center of the earth or any magnetic fields in the area.

    So, based on the assumption we use a properly designed plum bob with the attachment point of the string and the plum bob pointy end, both on a common center line, the string (straight string or limp string - but not an inferrior string that hangs off verticle) points from the top attachment point to the center of the earth forming what is referred to a "plum line". This would then mean that no two plum lines were parallel as they meet at the same point - the center of the earth. Imagine cutting a pie from the edge crust to the center, and the cuts being the plum lines. And no it does not have to be a plum pie as any type pie will do for the example.

    This would seem to be a concern as the greater the distance between the plum lines, the greater the error that would be encountered. Is there a formula to factor in for calibration of plum lines that are plum but not parallel by the nature of the process?

    And no, I don't have too much time on my hands, it is just that inquiring minds would like to know. :D

    One last thing: is the name "plum bob" the common name for the higher priced instrument called a Plum Robert ?
  5. Take a 2 liter bottle and cut the funnel end and about 3/4" of the side wall of the bottle off. Drop a ball of hamburger and a little water into the bottom of the bottle. Now put the funnel end you cut off, small end first back into the bottle till the cut edges match up, and staple it in place. (yes remove the cap first). Flies smell the meat and go in but can not find their way out.

    Or buy the same thing at the store for $10.

  6. Any horse person knows the collar goes around the horses neck and hooks to the harness, the clips go on the clops - the feet. Otherwise the horse could not go clip-clop when he walks. And when the police horse helps arrest a bad guy, it is called a clop collar.
