Inside the hard drives are Neodymium magnets that are super strong and are great for hacking into tool holders.
I added a magnet to my engine hoist to hold the lever used to raise and lower the hoist.
The original holder required you to put the pipe through a tube and was a hassle. Now its so quick and easy to grab and put back.
You can see the original post of this on my project car blog.
