Cutting
Built it, test it, change it. TeacherGeek™ components
allow you to design and engineer your most imaginative
mechanisms. Combine them with other materials.
Dowels and Connector Strips
can be cut with a multi-cutter
(best method), saw, side cutters
or pruning shears. Wear safety
glasses when cutting.
Dowels
Dowels vary in diameter.
Some may be too large
or small to use. Multi-Cutters
Cutters Reamer Screwdriver Pliers
Cut
The following TeacherGeek materials are needed to build one wind lift:
The following tools will be needed:
The Activity
This guide will take you through the process of creating a
wind powered lift. You’ll start by creating the stand. The lift
mechanism, hub and blades are then added. Before long you
will be experimenting with blade design and loading.
Tape String or thread
450mm (~1.5ft) Material for Blades Material to Lift
You will need to supply the following materials:
How The System Works
The ends of dowels may
taper and need to be cut

Step #1 Step #2
Holes & Reaming
Components
come with holes
that dowels press
securely into.
Push, Wiggle, Tap
Reaming holes to allow
dowels to rotate and slide
freely.
Ream
Turn a reamer back and
forth through a hole.
Push dowels into holes by:
1. Wiggling and pressing with your hands
2. Tapping dowels with a hammer or the
side of your cutter.
Tip: Rub a dowel
with soap, wax or a
crayon to allow it to
slide easier into and
out of holes.
Start Building!!! Most holes should not be reamed. Do not ream
holes which dowels should stay pressed into.

Attach two perpendicular blocks to a hole plate
using two #10 screws and two #10 nuts.
Do not ream

Step #11
A. Punch two holes on opposite
sides of a portion cup
B. Attach a 120mm (4.5in) wire

Cut
Step #13
Cut the points off the
skewer sticks.
shape of your blades, the number of blades used (between 1 and 6), and the blade angle.
Blades
Step #14
You will need materials for your blades (poster board, cardboard, plastic,
50mm
(~2in)
Below is one of best methods used to create a blades. You will need to
create 3 blades to start.
A. Cut a section of blade material. B. Place tape half over the edge of the
blade material.
C. Place a skewer stick at the edge of the
blade material, overhanging to one side.
D. Fold the tape and skewer stick over onto the
blade material. Press to secure the tape.

Step #15 A. Loosen the hub screw
1/4 turn to allow
blade skewers to slide in.
B. Tighten the screw
when blades are
positioned properly..
Attach the blades to the hub.
Experiment & Innovate!!!
Three or fewer sticks
can be inserted all
the way into the hub
holes.
Six Skewer sticks
can be inserted in a
hub as shown.
Load it up...
How much weight can your wind lift
pick up? How does the weight effect the
blade speed? Can your congure blades
for a heavy or fast lift?
Measure RPM, Torque, Work & Energy.
Engineer it for load/blade optimization.
Blades pitch
can be changed
when the hub
screw is loose.
Blades can be
cut, shaped, and
redesigned.
