Welding
Sheetrock jacks are used to lift and hold pieces of drywall in place when applying and attaching it to ceilings. You can make such jacks easily from two-by-fours, but they are only useful if you have somebody to help you with your drywall work. But if you have much mechanical expertise, you can build a Sheetrock jack that will allow you to Sheetrock a ceiling all by yourself.

Instructions
1. Cut a 4 1/2-foot length of 2-inch pipe.
2. Securely C-clamp the 2 inch pipe to a workbench. Cut a 3/4 inch slot in the pipe leaving 2 inches at either end.
3. Cut four 4-foot lengths of 2-inch angle iron.
4. Weld the lengths of 2-inch angle iron together to form a square base with a brace through the center. Make sure to turn the so a flat surface is facing up. Weld a caster to each corner. Weld an metal eyelet to the center back of one of the outside edges.
5. Cut three lengths of 1-inch angle iron, two of them 4 feet long and one 6 feet long. Cut a 5-foot length of 1 1/2-inch pipe.
6. Weld the three pieces of 1-inch angle iron together to form a capital letter "I". Weld the 1 1/2-inch pipe to the center beam of the capital letter "I," making sure to secure it on the flat side of the angle iron.
7. Weld the 2-inch pipe to the center of the caster base, to line up the slot with the eyelet that was welded to the base. Weld a 1 1/2-inch pulley wheel in the top 2-inch opening above the slot. Insert the 1 1/2-inch pipe into the base, making sure to square the "I" with the base.
8. Cut a small tab of metal 2 by 2 inches. Drill a hole in the center of this piece.
9. Weld the 2-by-2-inch tab on the bottom of the 1 1/2-inch pipe 4 inches up from the bottom of the pipe.
10. Connect the wire-rope come-along to the eyelet on the base. Attach the wire rope to the welded tab on the bottom of the 1 1/2-inch pipe. String the wire rope over the pulley and down to the wire-rope come-along.
