  1. No more than 400º. A lot of gas...........or a few pieces of wood.
  2. Good points Matt! Yeah, we should use oxidizing and reducing (and neutral) rather than rich and lean. Rich and lean describe the combustion while oxidizing and reducing describe their effect.
  3. Yeah, some folks have referred to my tongs as "ergonomic tongs" (popular moniker I guess), but I prefer what one smith called them many years ago; Eye sweet and hand friendly.
  4. If you don't know what you want to specialize in, just do everything you're able to. It'll come to you one day. Needs to be something you enjoy AND has enough potential to support you the way you require. Grant's #1 rule for success: Start out doing what everyone else is doing. At some point, start doing what no one else is doing.
  5. Pretty rare in the US with the unguided ram. The Brits often call this a "Rigby" type. Williams & White made similar ones.
  6. When calculating the weight look underneath. Most have a skirt about six-inches high and are only around 2" thick on the rest with a little ribbing. Some are solid. I had one that was kinda beat up and I flipped it over. It was solid and was machined on the other side too! Weighed 4,200lbs. 5 X 5.
  7. Nope! The frequency controls the RPM on any induction motor, number of phases has nothing to do with it.
  8. This fits what I have always understood of "killing" steel Background During the steel making process, oxygen may become dissolved in the liquid metal. During solidification, the dissolved oxygen can combine with carbon to form carbon monoxide bubbles. The carbon is added to the steel as an alloying element. The carbon monoxide bubbles are often trapped in the casting and can act as initiation points for failure. How Killed Steels are Produced and Their Advantages Formation of the carbon monoxide bubbles can be eliminated through the addition of deoxidising agents such as aluminium, ferrosilicon and manganese. In the case of aluminium, the dissolved oxygen reacts with it to form aluminium oxide (Alumina, Al2O3). The formation of alumina not only prevents the formation of bubbles or porosity, but the tiny particles or inclusions also pin grain boundaries during heat treatment processes, preventing grain growth. Completely deoxidised steel are known as “killed steels”. They have a more uniform analysis and are relatively free from ageing. For a given carbon and manganese content, killed steels are usually harder then rimmed steels. Disadvantages The disadvantage of using killed steels is they often display deep pipe shrinkage. Steels That are Typically Killed Steel that are generally killed include: • Steels with carbon contents greater then 0.25% • All forging grades of steel • Structural steels with carbon content between 0.15 to 0.25% • Some special steel in the lower carbon ranges Reference: http://www.azom.com/article.aspx?ArticleID=1697
  9. Hammers and presses are like some women. When a press says "no" it means "no". With a hammer, you can keep coaxing it along till you get what you want.
  10. Just wanted to add this picture before it disappears from Ebay:
  11. Probably, but I think he'd need more tooling than the small quantity would justify.
  12. You might be able to get one that is close and rework it. Do they care what blank you start with?
  13. Yeah, the pieces I've worked forged like butter or not at all. As soon as you got below the forging range it just didn't move. Much easier than steel.
  14. Good to know John. I have not used that brand, I was just looking at prices when someone said $300 - 500. Actually the only brand I've personally used is from Automation Direct, their GS-2 series. With no enclosure, 2HP is $250.00.
  15. Hi Tim! I'm Grant and I'm a recovering blacksmith. Hang in there, you'll become less tolerant as you get older. As I like to tell students "Remember: there are no stupid questions; only the ones you ask"!
