  1. When you visited IForgeIron, you have access to over 60,000 members in over 150 countries of the world, and their combined data base of information.

    The issue is how to solve the problem.  If you can not lower the anvil face, then raise blacksmith.  The end result is the same.  Take the information to the forge, test out the suggestions, then come back to the site, tell us how it worked. If you need other options, just ask.

    As blacksmiths, we tend to over think, over build , and over complicate things.  If that does not work, we break it so we can build it back, better than before, with modifications or improvements.  It is our nature.

  2. The term ‘denatured alcohol’ refers to alcohol products adulterated with toxic and/or bad tasting additives (e.g., methanol, benzene, pyridine, castor oil, gasoline, isopropyl alcohol, and acetone), making it unsuitable for human consumption.  This is followed by wear gloves, safety glasses, etc etc when handling denatured alcohol.

     

    One more question if I may.  My mix is 50/50 linseed oil, turps, a quart of both and an egg or so sized piece of beeswax. 

    At the store chicken eggs come in different sizes, small, medium, large, extra large, jumbo. Which size egg should I use as a starting point?

  3. Thank you for the follow up explanation.  

    The smaller the graduation on the scale, (ml vs quarts) and larger the quantity of the final mix batch, (gallons vs ounces)  the the more consistent and useful the mix.  Once mixed, storing in reasonable sized containers just makes sense.  

     

    Given your measurements, provides a reason to go to the shop and mix up a test batch, to see how it works here.  Thank You.

     

  4. Let is go back to the basics, and use mild steel.  Let's call black heat, as heat from ambient temperature to temperature that does not show color.  You need to throw in normal room lighting, or lighting in shadow conditions, into the mix. 

    The only way to insure repeatability as to touching it with a corner of my application rag and watch for the smokes heavily amount of smoke.  Once that happens, then to measure that heat, which should give you a number in degrees. Hit that number the next time and you are good to go.  

    This is true with many crafts, tighten the bolt to snug or use a torque wrench, set the temperature of the oven to bake a cake, or use an oven thermometer to be sure, driving down the road at a speed or looking at the speedometer, etc.  It is not shortening a learning curve but starting out at a known standard, or a reference point.

  5. There is a difference between just starting to smoke, just a little smoke, and rolling smoke. 

    Applying wax or oils at the melting points allows it to flow into and the small areas. It is an easy way to provide better coverage to the metal and therefore protection.   One question that keep coming up is when wax or oil and it smokes, what is left on the metal after the wax or oil vaporizes to smoke?  

    Experience level is sometimes difficult to put into words and pass that experience on to others.  Visual aids are one way.  Too hot to hold is subjective depending on the individual.  When using a wood cooking stove, the cooks can "feel" the right temperature.  Those using an open fire to cook on or with or wood fired pizza ovens learn by feel when the temperature is right or if the time needs adjusted without consulting a clock.

  6. Anvil  Use a rag, and start applying the finish when the black heat is too hot. It smokes off and remains grey. 

    Red heat, visible in the dark is 752*F on the Halcomb scale.  Black heat on that scale would be below 752*F. 

    I have heard that it is black heat up to 1000*F as a talking point

     

    Turpentine will be flammable as soon as it reaches the flashpoint that is 86*F to 115*F (30-46 degrees celsius). If it reaches the temperature and starts the ignition,  it will last until all the fuel burns out.

    Beeswax softens at 90 deg F (32 C) and melts at 143 to 151 degrees Fahrenheit. However, if you let it heat till its flash point— a higher temperature of about 400 degrees Fahrenheit, you could be calling for an explosion as the beeswax will ignite into flames. 

    Linseed oil ignites at 200° F. That means if the temperature goes close to 200°F.  The typical flashpoint of linseed oil is approximately 200 °F (93.3 °C). Flashpoint means the temperature at which a liquid ignites without warning when in contact with air.

    Black heat on that scale would be below 752*F.  If it flashes, I remove the can with my poker via the paint can bale and put on the lid. 

     

    All three ingredients have a flash point about 500*F lower than the temperature you are using.
