If you consider yourself a handyman, you probably own a Dremel or other
small rotary tool to help out with those finicky projects. In case you
wanted to make yourself a rotary cutting tool to add to your tool chest,
or maybe just play around with some motors, we’ve got you covered. This
project is super simple but the end result is a pretty amazing cutting
tool that uses an old bottle cap for the blade! Check out how to make
yourself a useful mini Dremel for cheap with just a few materials below.
I know that the first thing I did after seeing this video was make a
list of everything I needed and head to the store. So here’s what you’ll
need: A 9V battery, battery clip, hot glue, a small motor, a 2 terminal
switch, tape, a ballpoint pen, a hammer, scissors, and a knife. While
that may sound like a lot, you should be able to find most of that
around your house, and the rest at your local hardware store.
It is actually a fairly simple design, and in the video he uses it to
cut through some fairly tiny sticks of wood. You could probably cut
through a 2×4 with this, but it would likely take you several hours, and
many batteries of work. The one nice thing about this design is that if
your bottle cap blade ever dulls down, simply pull it off and hot glue
another one right on.
While you’re looking for a motor too, the MOXER drive motor available here, could be incorporated into this build as well to fully automize the cutting process.
