Kondia FV-1 Head disassembly

[stevec]

Darren, looking back at the drawing and at your pics, it appears there's an internal thread in the hole in the casting, probably for the #413-reverse trip ball lever screw. Could you make up a screw with that thread, drill it through with an appropriate tap drill. then screw it in against the, so far obstinate #167 reverse trip ball lever, jamming it to allow you to drill said Part #167 deep enough to tap it for an extracting screw? You'd probably have to redrill the "jamming" screw to clear your tap and "re-jam" #167 in order to tap it.
