  1. For the course at the New England school of Metalworking you need to factor in the cost of travel, lodging and food. So your $400 may become $700-800 pretty quick. Also remember that the cost of running school close to Boston is going to be higher and the school you went to only has 4 people at a time where the one in Maine has more than that so the one on one time with the instructor may be less. I have been to the same school you have and found that the information learned is worth the price it costs. That school offers a series of classes that take you from ground zero to a very broad technical understanding.

    It all boils down to what you think it is worth. In the spring come and join the New England Blacksmiths. We have a facility in Brentwood, NH that is open the last Saturday of the month (March through November) where there are a lot of guys willing to help you out and share knowledge. $20 / Year and $10 per Saturday. Price includes materials.

  2. The New England School of Metalwork is selling wrought iron on their site. Dimensions are 1.5 inch round (6lb per foot) and 1.75 inch round(8lb per foot). They are selling for $3.65/lb. Extra charge for forging to some other dimension. They claim to have sold several ton already. So you may be able to do better for your friend by holding it selling it as wrought than you would get at the junk yard.

  3. Doug,
    I always err on the side of caution but in this case the real question is: will the galvi-pipe get heated to the point where the heavy metals will gas off. I would bet that if the flame is periodically hitting it you will not have enough sustained heat to cause a problem. Also it is a flue so in the odd event some did gas off they would likely go up the flue and only take out any bird or squirrel that happened to be in the nearby trees.

  4. Ramachandran,
    do you know the actual type of steel? If you do there are plenty of resources on the web to tell you how to quench / heat treat a particular grade / alloy of steel. I agree with Dave that you may be getting the steel too hot. Also you may want to heat the back of the blade and let the colors run to the edge rather than heating the whole blade.
    Good luck

  5. As Mark Aspery has pointed out in the past and I have tried and successfully done, you do not need to build a bee hive. A good clean deep open fire will do the trick nicely. Also I have found that heating the pieces slowly so they are uniformly hot then bring to a welding heat seems to do nicely. I have started making a chain out of 3/8's round cut into 8 inch lengths and all but one link has been done in an open fire. The one time I could not get the weld to stick I had a big clinker in the belly of the fire. I removed it and all went well after that.

    Also, Frosty hit it on the head: use a light touch when sticking the weld. I normally use a three pound hammer for forging. I use a 12 ounce ball peen for sticking the weld. Not that I have to but I am too much of an oaf to control the heavy hammer when welding. I just get too excited at the site of steel at a welding heat!

  6. I keep a lot of coke from the prior fire so that when I get the new fire going it does not smoke as much. Add the green coal around the outside of the fire or at the bottom of the fire (I have seen a few smiths do this locally). Once I have a good fire going smoke never seems to be an issue.

  7. Tke a look here at the Handymans's essential book on google for a litle info on the topic.

    In short it says put a point on them and make it wedge shaped in all directions for maximum holding power unless there is a real danger of splitting. Also barbs on a nail decrease strength by 30+%.

    As for shape look here at the Tremont nail catalog for cut nails and you will see many shapes and almost all of them are tapered and almost all have a blunted tip.
