This hot knife idea isn't really mine, I found this idea made by somebody from MAKE:, I can't remember who made it. And so I decide to make one for my self to make my life of cutting hard plastic easier.
Disclaimer: This is a fairly dangerous work tool, it can burn and/or cut you if you misuse it. And I am not responsible what ever happens to you with this tool mod.
Step 1: What you will need...
- Any soldering iron will do - the higher the wattage, the better
- A nasty old soldering iron bit you don't want to use.
- A spare x-acto blade
My idea is to cut a groove into the soldering iron bit with my dremel with a cutting head. Then put the blade into the groove and squeeze the soldering iron bit onto the blade using the vice.
