- One cap should have a 1/4" hole drilled through it for the copper tubing. The other cap will have a threaded hole for a brass threaded plug that you turn down. Make sure the threads match.
- Put the O-ring on the brass plug.
Step #3: PrevNext
- Use the torch to soften the copper.
- Then use the pliers to bend it into the correct shape, being careful not to crush the pipe.
- Test fit it under the pop-pop boat engine to make sure it fits.
Step #4: PrevNext
- Make sure to apply plenty of flux to the inside of the pipe, then solder the non-threaded cap on.
- After that, solder the bent copper tubing into the cap, making sure not to get any solder inside the tubing.
Step #5: PrevNext
- Next, solder the threaded cap onto the copper pipe. Don't forget the flux.
- After that, clean up any holes or rough solder with the torch.
Step #6: PrevNext
- Cut a short length of cotton yarn and stuff it into the bent copper tubing.
- I used a stiff metal wire to help get it all the way in. You want a little of the yarn sticking inside the copper tube; this will allow it to soak up the fuel.
Step #7: PrevNext
- Use a wire wheel to roughly clean the burner.
- After that, polish it up on the lathe with fine-grit sandpaper.
Step #8: PrevNext
To run it, just fill it up with fuel, screw on the cap, and light the wick. That's it – you're done!
