How To Wire & Assemble Your Lamp Project:

1. Place steel washer, rubber washer & locknut onto end of threaded rod. 
2. Insert threaded rod into your lamp base. 
3. Add a rubber washer & locknut to top of threaded rod. 
4. Tighten against top of your base finger-tight. 
5. Slip vase cap, neck, harp base & socket bottom onto threaded rod & tighten finger-tight. 
6. Run lamp cord up through threaded pipe as shown in illustration below.
7.  Make an electricians' knot to prevent wire from being accidentally pulled loose.
8. If necessary, carefully strip 3/4" of insulation from end of lamp cord. 
9. If ends are not tinned, twist each section tightly. 
10. Wrap the wire with smooth insulation clockwise around the brass "hot" terminal screw. 
11. Tighten screw. 
12. Wrap the wire with ribbed insulation clockwise around the silver "neutral" terminal screw.

Choosing the Correct Size Lamp Shade & Harp (Shade Holder)

Generally, the height of a lamp shade should be the same or slightly shorter than the height of the lamp body. The circumference of the shade bottom should be approximately 2-1/2 times the circumference of the widest part of the lamp body. The shade should be placed so it covers the socket when viewed at eye level. 

Note: 2-Piece Harps make it easy to switch to larger or smaller Harps.

Thread Size Comparison *Note: 1/8 IP (Iron Pipe) does NOT refer to an actual measurement. It is just a trade designation for the standard size of threaded lamp pipe used in lamp making.
