31st July 2008 - Right Elevator Complete

Finished the work on the right elevator by making a rectangular steel cup into which I could melt some lead. I then drilled an air hole in the inboard end of the elevator horn and poured the lead into the open outboard end. This nearly worked until the lead set in the horn before flowing all the way round so two blowtorches were used to heat the horn and melt the lead to allow the rest to be poured in. The elevator was balanced just slightly front heavy to allow for the weight of the covering. The airhole and top tube were then welded shut. Finally all the remaining joints were final welded and/or brazed and the flux removed.
