YT video how a 12 nozzle chipshooter head works in details (disassembled)

[Kjelt]

Not sure if this was ever posted earlier.
Having disassembled a simple P&P head my self last year for fun and learning, I just came across this video explaining in detail how a Siemens Siplace 12 nozzle chipshooter head works 
Its like a gattling gun but a lot more complications, see for yourself.
Anyone dares to build one
