[C320-list] Mainsail furling screw update

[kendgb]

Can you just replace the part?  If it is irreplaceable can a larger screw be used, is there room?  If you need to reuse the part and the same size screw then you do not want to break off a drill in hard to drill SS or later break of an easy out. Closing some doors.You might want to investigate taking the part to a machine shop with EDM (electrical discharge machining) and having the screw removed using EDM, a well established method.

If you can make a little dam using tape try flooding it and leavingovernight or longer and have another go.  May take more than one go but let the magic fluid do its work over time.Regards,Stephen CoxTegwen #1141
