Step 5Warning!

Warning!
I found that heating the awl made this part of the job easier. The business end of the awl was made hot by holding it in the flame of a cigarette lighter and then it was pushed into the tube, enlarging it in the process.

WARNING!!

Fire is hot. It will burn you. The awl is a sharp instrument, and if you poke yourself with it might hurt you. If you heat it and poke yourself in the eye with it you will lose the vision in that eye.

So, regardless of what they say over there at MAKE, do not do any of those things. Stay safe.
