That professor may have been annoying but you never found out if he had something to teach you or not. Some of my most intimidating and or annoying instructors were the ones I learned the most from. I will send a 5" chunk of 1-1/4" to anyone willing to give this a shot if you don't have the material, but in return you must post the results.

How the hammer is held and manipulated by the hand is vitally important to effective forging technique and an important part of maintaining healthy joints. Basically what is shown below is the bottom part of my down swing. These pictures show the action of the hand. While loosely gripping the hammer handle with the thumb and index finger which also act as a fulcrum, the lower three fingers act to lever the hammer down for additional acceleration, (additional to the wrist and arm motion).

Upon rebound the hammer head quickly is returned to a position above and behind the hand which reduces strain on the wrist and uses the large muscles of your arm ( and maybe body) to raise the hammer for the next strike.

I ain't no spring chicken - This is just a small snippet of the whole picture but a method that has allowed me to continue forging long beyond the point that my body said stop. If you do not agree I invite you to provide a similar graphic presentation showing a better way.

The rubber mallet was used to void damaging my anvil.

Is it allowed that I do the whole tool in one heat under a power hammer?

gonna be hard to make a hardy tool for a 1 inch hardy upsetting 1 inch square.

I did make a turning fork that way, I hot split a few inches of 1 inch square 1045, spread the halves and worked them round, then shaped the halves up using a steel spacer. It sits in the hardy on the spread for the fork, and works very well. It was also surprisingly easy to make.

The only thing I don't remember is if I cut the stock off to length first, or last (I think I cut it first and used tongs)

OK, I did write "Challenge" but it wasn't really a challenge. It was more a dig at those whom say/write "only my way is the right way" So far, most of those folks have stayed quiet.


I think one inch would work fine for a hardy tool. Simply upset the mass about an 1 1/2 -2 inches from the end and than draw down the end. If I was doing it, I would start with a long bar and cut off after I did the upset and drawing.

You have a good point Gerald. Upsetting 1 inch enough to stick in a 1 inch hardy hole for further upsetting is rather easy, you don't need to upset it very far at all. Upsetting it a bit towards the middle (chill the end some?) would give more material at the end to work with.

How come the bar must be drawn to a point for the shank of a hardy tool? I realize that many hardy tools have shanks that are drawn to a point. But many old ones are nearly straigth sided, and seem to fit just fine in hte hardy hole. A partial taper would take less time to do.

So I do plan on attempting this as an exercise after I complete just *one* of my many other unfinished projects, but I have to second freek's question. I've made a few hardie tools out of 1 1/8" inch axle stock, and just fullered them down to 7/8" square, then upset and finished. Why bother with the taper? It seems like a lot of unnecessary work, especially if you're sans power hammer.
