Here's a fast and easy way to make a menorah out of some hex nuts, washers, and metal epoxy.
10 x 1/2" Hex Nuts
9 x 3/8" Hex Nuts
10 x 5/16" Washers
Sheet of stiff cardboard
Step 1: Attach Washers to the 1/2" Nuts
Mix the epoxy and glue 10 washers onto 10 of the 1/2" nuts.
Step 2: Glue 3/8" Nuts on the Washers
Put a small amount of epoxy on the bottoms of the 3/8" nuts and glue them onto the tops of the washers, rotating them so that the flat side of the 3/8" nut lines up with the corner of the 1/2" nuts as shown.
Do that for 9 of the ten washer-nuts.
I lack the mad epoxy skills so mine are a bit messy. You might want to practice first on some extra parts to see how much epoxy you'll need.
Step 3: Make the Shamash Candle Cup
Epoxy the last washer-nut to the bottom of one of the nut-washer-nuts. This time, make sure the two 1/2" nuts are lined up.
Step 4: Attach the Candle Cups to Each Other
Put down the sheet of cardboard to protect your table from the expoxy. Add some epoxy on one side of the 1/2" nut and attach it to the side of the next. Make sure there are four cups on each side of the tall one.
Step 5: Light It Up!
Let it cure and you're ready to celebrate. You can secure the candles in the nuts by screwing them in about half a turn or so.
