TOOL1
Start by removing the small screw
used to secure the Dremel no. 407 ½"
(diameter) sanding drum to the no. 402
sanding drum mandrel.A HANDHELD MOTOR tool is arguably
one of the most versatile tools any hobbyist
can own. While its many uses at the work-
bench or in the shop are well
known to hobbyists, don’t under-
estimate how handy it can be in the
garden. As shown here, I discovered
an easy way to turn my cordless rotary
tool into a simple string trimmer. It’s great for
clearing weeds along the railway right-of-way.
If you want to make one yourself, just be sure
to select a variable-speed tool with enough torque to
power through the vegetation you want to reduce. In most cases a
1-amp electric or 8-volt cordless option should be adequate. Of
course, always be sure to wear safety glasses and appropriate attire
(gloves, long sleeves, and dust mask) when using this device.2
With the drum freed from the mandrel,
use a blunt shaft to separate the abrasive
sleeve from the rubber core.3
Use a screwdriver to pry the top washer
from the core. Note that the top (small
opening for screw) and bottom (large opening
for mandrel) washers are different sizes.4
Now use a razor saw to cut two,^1 ⁄ 16 "
deep notches across the top of the core.
Make one cut on each side of the core’s
centered opening.5
After cutting two pieces of^1 ⁄ 16 " nylon
string line to approximately 10" lengths,
install one (equal length extending from
both sides) into both notches.6
Reassemble the washer, screw, and
mandrel, and then secure the trimming
unit as directed in the motor tool manual.
