1 - Research (you never know enough) --> in progress

2 - Make a cardboard mockup ( in my plan that will ease the space required, and I will be able to adjust size in a really cheap way! )

3 - plan the instrument building process carefully ( what will be built first )

4 - gather tools and other hardware

5 - build

6 - repeat step 3 to 5 as needed

7 - sit back and enjoy

8 - fix.. cause you always will need to modify parts... this is a neer ending hobby... ask anyone!!
