Step 2: Disassemble IKEA Stollet Lamp
Carefully disassemble the IKEA Stollet lamp. The ceiling mount will not be needed & should be removed. Just remember to keep all the wiring intact. I had to use metal shears to clip through the metal discs.
Be sure to KEEP the metal plate/disc that covers the top of the lamp (top, that is, when it's used as a hanging lamp). You'll need to thread this off of the lamp's wiring for later use. Happily, this disc just unscrews from the top of the lamp; then it's just a matter of pulling all the lamp's wiring through its hole.
In photos1 & 2 below, it's the part of the lamp to which the red arrow is pointing (for clarity's sake: please note that the silver metal band you see on the outside edge of the lamp is attached to the acrylic. The piece to which I'm referring screws to the top of the lamp and is hidden from view by that metal band).
Take notice of the width of the lamp's threaded base. You'll need this width in the next step.
