You Know Where To Put the Cork*

Building the bottle hardware that fits the top of the bottle isn’t always straightforward. I try to use as much original material as possible to retain the spirit of the brand.


  1. Place a piece of painter’s tape on top of the bottle’s top for easier drawing.
  2. Use a ‘center scribe’ (red tool in photos) to draw lines at different angles across the painter’s tape.
  3. Use a scratch awl to press a point into the center of the lines that I drew on the top.
  4. Hand-drill a very small shallow hole into that point, then one slightly larger as a starting point for the large drill-bit.
  5. Wrap the cork with painter’s tape.
  6. Clamp the cork into a drill-press vise, being careful to keep it level against the top.
  7. Drill a hole large enough to fit the 3/8″ threaded nipple through the top into the cork itself. I use a ‘Pilot Point‘ bit for more accuracy.
  8. Remove the tape and clear off the dust.
  9. Locate a threaded nipple that will fit through the top / cork with 1/4″ to spare on either side (this often involves cutting a large nipple to size with a dremel tool equipped with a cut-off wheel).
  10. Thread the bottom of the electrical socket onto the top.
  11. Thread and tighten a washer and nut to the bottom on the cork side. The washer may be too large for smaller bottle openings; you may have to find a smaller washer or go without.
  12. Wrap the cork with electrical tape (as needed) to provide a tighter fit.
  13. Rotate the assembly so that the socket screw, etc. faces the back of the bottle.

But what if the top is plastic or metal screw-on with no cork? I repeat the same steps as above, but I add a bottle plug to the underside of the cap to extend the nipple length and build stability. I may add a seating ring to the top if the cap is damaged (or ugly).


What if the bottle doesn’t have a top at all? Maybe you forgot to save it, or maybe it’s a bottle of Blanton’s and you can’t really attach the light socket to the horse 😉 . Well, in that case you have two options:

  1. Find a spare cork that’ll fit.
  2. Use a bottle plug / seating ring by itself. I did this on the Blanton’s lamps (#1, #6).
