Having just completed a fettle on a very recent purchase, an incomplete Primus 96 dated 1922 and eager to see how she could perform, I pinched a spirit cup and a flame spreader from another 96 and eagerly completed the stove rebuild, along with a good glugg of the amber fluid she was primed and ready to go. She was running beautifully.. I had my face up to the burner basket surveying the performance, flame pattern.. (and all that stovie talk) then....CRACK !!!! I must admit I was close to letting a bit of wee find its way into the fabric of my trousers... but not quite at that age just yet.. A fragment of something shot across the kitchen .. what was it ? where did it go ? I killed the flame on the stove to see the flame spreader sporting a small crack and a chunk of metal missing .... Has this happened to anyone else ? Lesson learned for me.... safety glasses to be worn at fettle corner from now on.
