I found this beauty in a thrift store. According to the owner it was still in working condition and some of the extra parts came with it (more on the "working condition" later). Nevertheless I decided that it had to be transferred into a dimmable kitchen table lamp.

Step 1: Disassembling and Cleaning

Pretty easy: take everything apart, keep the housing, keep ALL the screws, keep the switches and throw away the leftovers. Then give everything a good rinse and rub to get rid of several coatings of kitchen dirt.

Step 2: Wiring

Fix the light socket with a fine thread tube to the housing and pull the wires trough.
Important: from here on do the wiring first and then put all the switches in place (and let enough slack)
The blender had a "push-and-hold" button, witch I replaced by an on-off switch of the same size (I could even use the old switch cover).
I disassembled a wall mounted dimmer switch and used it for this lamp. It fitted perfectly, I could even fix it on the original screw holes.
As cable I used an extension cord and cut of the female plug.
When all the wiring is done reassemble without the baseplate.

Step 3: (Almost) Done!

Put the on-off switch in place and screw on the original cover to fix the switch in position.
Fix the old knob on the new dimmer (needed some glue in my case).
Screw the base plate back on and enjoy your new table lamp.
