Step 9The stubby version: better insulation
I needed better thermal insulation for the part of the device that's actually held between finger & thumb. It occurred to me that the plastic used for a soldering iron body is a reasonably good insulator considering how hot the heating element gets, and how close it is to your fingers.
So I took apart an old soldering iron and cut down the barrel to make a stubby housing for the heating element. Unfortunately, the element was slightly too tall to fit entirely inside the barrel, so I had to cut out a slot in the top; it fitted snugly though.
