Hi All,

Christmas times, I wanted to gift a toy to my son which he could enjoy and get him involved while making it.

During the build, my son ( 8 yrs) helped me with tools and paint work. Good way to teach kids some basic carpentry

In this intructable I will share my how to make mini catapult for kids. Without using nails or screws ( well almost, I used just 2 nails and 1 screw for the build) And using hand tools.

So anyone could try to make this at home, who do not have professional power tools

The design is for people with basic knowledge in carpentry, For beginners refer to my catapult v1

Step 1: What Do We Need ?

Material

0.75" x 0.25" Wood strip (5 ft long)
PVA glue or fevicol
Cotton Yarn
1 Wooden skewer
Spherical cap / Lid (cadbury gems surprise )

Tools

Hex saw with miter box ( Must )
Acrylic paint ( Brown and Green)
Paint brush
Sand Paper

Step 2: Wood Cutting

Cut Wooden strip into following sizes

Bottom Long Pieces - 8 inches - 2 nos
Bottom short Pieces - 4 Inches - 3 nos
Arm - 6 Inches - 1 no
Side frame - 4 Inches - 2 nos
Top rest -5 inches
and one wood strip approx 3.5 inches, But we need to adjust based on how good cuts we make

We need to make 0.25" groves to interlock two wooden pieces. I used paper tape to hold the pieces together and then made the groves.
Please note the direction of wood grain. If not done correctly the piece goes bad and we need to start over for that piece.
The Middle bottom piece holds long and the side frame, so the grove is 10 mm and interlocked from bottom side.
Fix a lid on the arm as shown.

I have added Sketchup
