Important Update: This doesn’t work! 🙁
I thought this was going to be an awesome re-purposing of my old hand mixer but turns out these things arent meant to be used for more than a few seconds at a time.
The second or third time I was using it, I went for about 10 minutes and it overheated and caught fire. I wouldn’t recommend going down this path.

I planted a lawn out the back of the property where the gardener couldnt get to without a key so I needed something to cut the grass. My lawn mower is a bit pre-occupied and my weed-wacker was wacked. So in the usual recycling manner I made my self a string trimmer (weed wacker) out of an old hand blender
Wow look at that, badly thrown together lense flare, a fluro background. This thing HAS to be awesome.
To be honest, the only reason I am calling it MK I it because its rather hastily assembled and has some design uglies, I’ll probably never rebuild it because it works* (edit: not really see top of this page) and that’s all I care about.
So I started with an old hand mixer/blender motor I had lying about, and thought about strapping it to a peice of wood, without anything else more suitable I made a sort of wooden vice with two threaded steel rods and 4 bolts. This worked really well!
I basically just nailed the control board onto the length of wood for now, holds fine, but I had to wire up a switch. In the interim I have some twine nailed to the board, going over the switch with another small peice of rubber, then round a nail and back to the top of the board for a lever.
bill of components
* about a 1/4 of some threaded steel I bought a while back
* a 6cm bolt for the lever
* 5 bolts
* cut mains cable I had left from another project.
* some weed wacker twine for the controller and the cutting part.
