Step 1: Materials
So, the materials for this project are pretty straight forward.
First you will need a key or several keys. I had a bunch laying around that I had picked up over the years.
you’ll also need the following:
A blowtorch (or other heat source)
a mandrel (for sizing) I did not end up using mine in the end
A pipe to rap the key around (I used some scrap that was similar in size to what I wanted, but you could also use a steel Mandrel to get a perfect fit)
A hammer (I used a regular hammer for the grunt work and a jewelers hammer for some finer touches)
A pair of vice grips
Some metal polish
A dremel with a buffing attachment
Step 2: Heat it up
Place the key under the flame of the blowtorch. Wait till it starts to a light pink, then dip it in some water (I found it to be to brittle if you tried to bend the key when it was to hot)
ATTENTION: Please make sure you use blowtorches outside or in well ventilated areas.
