Materials Needed:
1. 2x6 lumber (4 pieces, 8 feet long)
2. 2x4 lumber (2 pieces, 8 feet long)
3. 1-inch carriage bolts (4 pieces, 4 inches long)
4. 1/2-inch carriage bolts (4 pieces, 3 inches long)
5. 1/2-inch washers (8 pieces)
6. Galvanized steel chain (10 feet long)
7. 1/2-inch clevis (2 pieces)
8. 1/2-inch pins (2 pieces)
9. Hammer
10. Drill
11. Measuring tape
12. Pencil
13. Wood screws
14. Sander
15. Stain or paint (optional)
Step 1: Preparing the Materials
1. Cut the lumber into the following lengths:
- 4 pieces of 2x6 lumber at 36 inches long
- 4 pieces of 2x6 lumber at 28 inches long
- 2 pieces of 2x4 lumber at 24 inches long
Step 2: Assembling the Frame
1. Take the four 36-inch 2x6 lumber pieces and lay them on the ground in a rectangle, with the shorter edges facing each other.
2. Place the two 24-inch 2x4 lumber pieces inside the rectangle, one near each end. These pieces will act as cross-supports.
3. Drill pilot holes through the 2x6 and 2x4 pieces where they intersect, being careful not to drill all the way through.
4. Secure the frame using 3-inch carriage bolts, washers, and a hammer.
Step 3: Attaching the Lifting Arms
1. Cut the remaining two 28-inch 2x6 lumber pieces in half, resulting in four 14-inch pieces. These will be the lifting arms.
2. Attach the lifting arms to the frame by drilling pilot holes and securing them with 4-inch carriage bolts, washers, and a hammer.
3. Position the lifting arms so that they angle outward from the frame.
Step 4: Adding the Chain and Clevises
1. Take the galvanized steel chain and cut it in half, resulting in two 5-foot pieces.
2. Attach the clevises to the ends of the chain by sliding the pins through the holes and securing them with a hammer.
3. Hook one end of each chain to the lifting arms and secure it with a pin.
Step 5: Finishing Touches
1. Sand the entire log jack to smooth out any rough edges.
2. Apply a coat of stain or paint to the log jack for protection and aesthetics (optional).
Your log jack is now ready to use! Simply position it under a log, hook the chains around it, and lift by pulling on the chains. The log jack provides leverage, making it easy to lift and move logs safely and efficiently.
