All the cool kids are drinking Moscow Mules. Traditionally, they're served in copper cups, but those can get pricey. We can make our own copper cups with nothing more than 3/4" copper pipe that you can find in any hardware store, or even scrap yard.
Step 1: Tools and Materials
This project is pretty simple. I've never done any copper soldering or metal work before. I was able to use my 3rd and 4th cup I made at home. Here's what you'll need to get started:
- Propane Torch
- No. 5 Flux
- Solder (Lead free for copper pipes)
- Hacksaw or Sawzall
- 2 pairs of pliers
- Large hose clamp
- Tin snips
It would also help to have a bench vise and a grinder, but they are not necessary.
Step 2: Split the Pipe
Start by slicing your copper pipe down the middle with your hacksaw or sawzall. This cut needs to be extremely straight so take your time. I cut my pipe down to one 11" long piece and two 4" pieces.
Step 3: Pound Flat
Split the pieces open with pliers and then pound it flat.
IMPORTANT: Fold over one long edge of the 11" piece to protect your lips from getting cut. See my YouTube video for more instruction.
Step 4: Wrap Copper Around a Form
Find some sort of cup sized object you can use to wrap your copper around. Preferably steel. I used the wheel off of a floor jack. Use a large hose clamp to force the copper into shape.
Step 5: Bend Over the Bottom
Bend over a small lip on the bottom of your cup to make a nice seam.
Step 6: Solder the Joint
Leaving the hose clamp in place, solder the joint together with the torch.
Step 7: Remove the Form
Use a hammer to remove your cup shell from the form. It should look like this. Notice the top edge has been completely folded over and the bottom edge has a small lip.
Step 8: Solder Bottom Together
3/4" pipe does not open up wide enough to cover the whole bottom. You'll need to solder a seam between two pieces to make one large enough to cover the hole.
ALTERNATIVELY: You could use 1" copper pipe or find copper sheet metal. Neither were available locally in my area.
Step 9: Cut Out the Bottom Shape
Mark and cut the bottom of your cup. I used tin snips to cut to the outside of my line, and then used the grinder to form a perfect circle.
Step 10: Solder Bottom
Heat the outside of the cup while soldering the inside to attach the bottom to the shell. See my video for more instruction.
Step 11: Make a Handle
I used a 3" piece of pipe folded over on itself for the handle. Shape with the hammer.
Step 12: Attach the Handle
Attach the handle to the cup at the seam. Put the hose clamp back on the cup for this step in case you were to loosen the solder holding the shell together.
Step 13: Polish, Clean, and Enjoy!
Use a wire brush to clean all of the flux, dirt and grime off of the cup. I used one that attached to my drill. Overall, I'm happy with these cups. They aren't perfect, but I learned a lot and they do their job. See my video for more instruction.
