This is not your father's Menorah. The Grunambulorah is made from old radio tubes, LED's, plumbing fittings, knife switches and it's all powered by 2 AAA batteries. I love the warm glow and it's got that funky Steampunk vibe. Here is how I did it.


Step 1: Materials and tools

Tools:
  • Dremel with 1/4 inch glass cutting bit.
  • 3/16 inch regular bit to elongate the hole inside of tube
  • Table Saw
  • Tape Measure
  • Hammer
  • Drill with 1/16, and 1/8 inch bit to drill pilot holes
  • Soldering Iron
  • Heat gun to shrink tubing.
  • Sandpaper
  • Screw driver Materials:
  • solder
  • 18 gauge wire
  • 9 knife switches
  • 9 red led's
  • double AA battery holder
  • 2 AA batteries
  • 9 radio vacuum tools of assorted heights
  • 9 47-ohm 1/4 watt resisters
  • 9 copper pipe connectors with 1 1/8 inch inside diameter
  • 9 PVC caps with 1 inch diameter
  • Oak 1/4 inch thich
  • Hot glue
  • Gorilla Glue
  • White Carpenter's Glue
  • Screwdriver
  • Hammered brass spray paint

    Step 2: Drill the vacuum tubes

  • For safety wear eye protection. The bit will send small glass particles flying. The Dremel does not actually drill the tube but actually grinds it gradually.
  • Decide where to drill the tube. The best placement is somewhere you will be able to feed the LED up so that the whole tube glows. Tubes have a layer on the bottom that would shield the light but the layer is easily drilled thru
  • Put a drop of cutting oil on the tube.
  • Put the dremel on high speed and let the bit gently rest on the glass. It will begin to grind away the glass. DON'T push it or the tube will break.
  • Put more oil on about every 5-10 seconds. Don't let it dry out.
  • Be especially careful just at the end and don't let the Dremel slam into the tube.
  • remove the small piece of glass from the drill bit. See the photo. It looks like a small button.
  • use a 1/4 or slight smaller drill bit to pierce the bottom shield of the tube so that you can feed the LED up.

    Step 3: Prepare and insert the LED's

  • Using 18 gauge wire, attach extensions onto the LED. Use red for the long positive tail of the LED.
  • Use shrink tubing to insulate the leads. Shrink the tubing with a heat gun or soldering iron.
  • Feed the LED into the tube.
  • Fix in place using hot glue

    Step 4: Insert the tubes into the copper pipe fittings

  • Put the tube into the pipe fitting. Try to seat the tube just so that the LED is right below the lip of the copper fitting.
  • Use hot glue to fix the tube in place

    Step 5: Measure the base and cut

  • Lay your tubes out on the Oak board and decide what dimensions you will use. My dimensions were: 16 1/2 X 5 1/2 X 2.
  • Cut the board and lightly sand the edges.
  • Put tung oil on it in order to seal the wood and bring out the grain.

    Step 6: Optional: Drink a beer. It's thirsty work.

    Today's beer is Sierra Nevada Pale Ale. Always a solid choice.

    Step 7: Paint the PVC Caps and fix them to the base.

  • Using the hammered brass spray paint, or a paint of your choice, paint the PVC caps.
  • Drill a pilot hole in the bottom of each cap
  • Using a DROP of gorilla glue put the cap in position and then use a small screw to fix it to the base.
  • I set the Shamash back 1/2 inch.
  • Let the gorilla glue dry
  • Drill a 1/4 inch hole thru each cap and thru the base to have the LED wires pass through

    Step 8: Glue the "candles" to the bases

  • Feed the wires thru the hole in the bottom of the cap
  • Put a few drops of gorilla glue on the cap sides
  • Slide the copper fitting over the cap. The gorilla glue will expand and keep it fixed in place

    Step 9: Attach the knife switches and drill holes for the wire to pass through

    Steampunk Menorah: The Grunambulorah
  • The knife switches are attached with screws right in front of each "candle"
  • Drill 5/16 holes for the wires.
  • Attach wires to each side of each knife switch and feed them through the 5/16 inch holes. I used one hole for each two switches.

    Step 10: Final Wiring

  • Follow the schematic diagram.
  • In this step you are soldering the resisters to the positive lead of the LED
  • Then you are attaching the knife switch to the resister
  • Then you are attaching the other side of the knife switch to a bus carrying the positive voltage.
  • Then you are wiring the negative leads to a buss carrying the negative voltage
  • Then you are using gorilla glue to fix the battery holder to the case.

    Step 11: Using the Grunambulorah

  • Each knife switch turns on a "candle"
  • For my Non-Jewish nerdy friends that decided to make a Steampunk Menorah (and I know that there are legions of you out there...) You start with the Shamash and then each night increase the number of candles going from right to left.
