Timeline 2017

January 2017

The feasibility study started in January 2017. The official start date for The LUGIRO Project was 4th of March 2017.

February 2017

Measuring minimum pressure on string to avoid fuzzy sound, 0,4 - 0,8 kg. The first choise of pneumatic components: valves, tubes, fittings and cylinders. The cylinders on the fretboard were later changed.

March 2017

Test of cylinder pressure against the string.
Planing and buying equipmnet: 3-way valve, 5-way valve and double working cylinder. 
Teoretical calculation of cylinder frequency and speed. Buying guitar in parts.

April 2017

Using a manual car pumpe and a 0,6 l aluminium bottle as air comressor/tank.
Testing of valves: minimum needed air pressure: 4 bar.

May 2017

Buying more equipmnet after successful testing.

June 2017

Buying 3D-printer. Testing of 3D-drawing software: FreeCAD

July 2017

Assemling the guitar an give name to the guitar: AIRcaster.
Buying small 12 VDC air compressor.

August - September 2017

Working with the first fret block system (later abandoned). 3D-printing and testing.

October 2017

Problems to solve:
- Warping when 3D-printing
- Hard shock from fret cylinder arm on string
- Width of fret cylinder block
- Coil on valves not working properly

November 2017 - March 2018

Workshop area shut down in the winter because of low temperatur.
Searching for solutions of the encounterd problems,
