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.

Step 3: Clamp and Hammer

I clamped the key to the end of the pipe (placed some cardboard between the vice grips and the key to prevent scratching) and slowly began to hammer the ring around the pipe. I had to heat it two more times to get the desired shape.
