This is my first instructable, made in ye olde village smithy at The Crucible. This hook design is taught in the beginner blacksmith's class. This is intended as a teaser for the full class, which will go much more in-depth on the specific techniques addressed here.
Be Wary! Treat all metal within a shop as if it is hot. You're working with very hot objects and serious damage can happen if you don't know what you're doing. Wear gloves! Wear eye protection!
Step 1: Gather Tools
1. A forge (I used propane, but gas will work)
2. Blacksmithing hammer (10 lb)
6. Twisting Wrench
Step 2: Place Metal in Forge
Use your tongs to place the material in the forge, and let it heat up. Gloves highly recommended.
Step 3: Flatten Wall-Hanger Portion
Be sure to hold your bar level with the anvil! It should thicken to approximately 1/2 inch wide, with a good shoulder to mount on the wall.
Step 4: Punch Screw-Hole in Flat Portion
Place punch in desired location and use it to pin your hanger to the plate, and punch through the metal with a few hammer blows. Be sure to hold the punch completely perpendicular to the anvil face to get a clean puncture.
Step 5: Taper the Other End
Swing your hammer with angled blows, and draw out the end of the material to a taper. This should be done with multiple heats. Continue to draw the end out until you have a nice taper, about three inches long.
Step 6: Create Your Scroll Tip
With the shoulder of the metal facing upward, place the tapered tip over the edge of the anvil. With light glancing blows, bend it slightly around.
Flip the material, and hit the metal towards you to get a scroll tip. The material should be against the anvil, and the angle should dictate how the curl looks.
Hammer control is very important! At the tip, you should use light strikes, but as your angle steepens, and you get towards the thicker material, your hammer blows should increase in magnitude.
Step 7: Bend Your Hook Around the Horn!
Rotate your material 180 degrees, and lightly start to curve the material about the horn on the anvil. Use glancing blows, and hit just over the edge of the horn, without directly striking on it. You're creating a smooth curve that will form into a J shape.
This is pretty tricky to get a nice curve, so work slowly, and don't be afraid to take another heat.
Step 8: Decorative Hot Twist!
Take it out, and put the J portion into a vise. Do this quickly, as the heat will bleed into the vise, and mess up your bend.
Grab the upper end with your twist-tool. You can use a pipe wrench if need be, but be careful to twist it evenly.
Now, Twist! Give it a full 360 rotation. Be sure to keep the angle of twist parallel to the ground, or your bend will be skewed. Be sure to align the original angles of the material for a full rotation, or you will have some funky angles.
Dont't be worried when your metal starts to shed scales. It's just molting. The scales are a natural part of growing up. They will come off in hot flakes.
Step 9: Finishing Touches!
Place your shoulder flat against the anvil and note if there is any wobble. I balanced mine with a hammer. Feel free to heat it up, pick it up with tongs, and try and hit it flat against the anvil.
If you've got a wire wheel, brush off all the slag and flakes that you worked into it. It'll turn into a nice sheen.
Be sure to clear coat! Polyurethane spray paint works well. Otherwise, your hanger will rust.
