Metal Dice Project
Objective: Learn to construct a simple steel structure.
Provided Material:
1. 1/8” X 3” steel flat bar stock
Instructions:
1. Cut 10 3” X 3” steel squares. 6 of the squares will be used to create the dice and 4 will be
used to practice drilling and welding.
2. Grind, file and sand the 6 dice squares, insuring the edges are straight and all the squares
are the same size.
3. The 4 remaining squares should be used to practice the steps below. A good starting point
for the Millermatic 211 MIG welder is 0.035” Auto-Set Weld Wire Diameter and 1/8”
Material Thickness. The wire speed maybe a little fast at this setting. An alternative
starting setting is 37 Wire Speed and 6.5 Volts.
4. Using the attached pattern, drill the “spots” on the dice squares. Start the holes with a
small pilot hole and then enlarge them to 5/16”. Bevel the edges of the holes with a drill
bit at least 1/2” in diameter.
5. Using a large piece of angle iron as a jig, tack weld two right angles. The first right angle
shall be made of the “6” and “2” squares. The second right angle should be made of the
“5” and “1” squares. Keep the number of tack welds to a minimum. Three tacks, one in
the center and two 1/4” in from each edge, should be sufficient. After tack welding,
insure the pieces form a perfect 90°. You may need to use a hammer to adjust the angle.
6. Tack weld the two right angles to form a square. Tack weld the “3” and 4” squares to
create a cube. Weld up all the seams of the cube.
7. Grind, file and sand the cube to create a dice. The belt sander is very helpful in creating a
“brushed” finish.
Instructor sign-off:
Note: When welding an enclosed structure, there must be a way for the expanding hot gasses to
escape.
Note: Structural welds are left intact. The welding joints for this project are shaped for cosmetic
reasons.
