Took about 5-10 hours of preparation... that was stuff like finding the blueprints and setting up a temporary hot wire cutter, and the actual making time was about 40 hours (Wire cutting 2 hours, angled wire cutting and major details 10 hours, finer details 15 hours, electronics and display 5 hours, tube reinforcing 3 hours, painting about 3-5 hours). I'd never attempted anything like that before though, so I could probably do it in about half the time now =D
