No, just a hobbiest with a good Stihl woodsaw . I designed the chair first on a CADprogram, After that I plotted it 1/1 so I could use the papermalls to draw on the 18mm MDF. Would be even better with a CNC machine. But I don't have that. I'm putting 40cm legs underneath the seat so I get on the same level as my beamerscreen. My son of 5 and daughter of 8 as well as I can use the flightseat because it's totally ajustable. I'll post some more pictures when it's done.
