How I Made Kalimba

I had seen  That some people make homemade kalimbas aka thumb pianos.
I decided to make some kalimbas.

First someone in family drunk tea. There I got tin can. Then I cut aluminum rods and one bigger rod.
I drilled holes on can, rods and bolted rods on can.  

Next I tested keys for my kalimba. Hair clips was too  thick and didn't sound good.
Metal saw blade braked under tension. I found laying a round some mini hands saw blades.
Saw blades sounded best.

I wanted to make kalimba for my 5 years old brother for birthday . I started to make new one. I find little oval tin can.
I realized that I need to make saw blades safe for kids. I Removed  blade grains and sanded smoother edges.
