Thanks.
Tilly, the plug was the worst part to do and took me from scratch to complete/polished ready for mold 56 hours.
Fitting mold flanges, gelcoat & laminating/reinforcing of mold took about 5 hours and the actual laminating of part in mold 1.5 hours and about half an hour getting mold of plug and part out of mold.
IOW, total time from scratch to part = 63 hours excluding curing times.
Can now produce a nose cone in 2 hours flat
BTW, the scuttle plug, mold and part is done and currently the bonnet mold is on the plug ready to be taken off and the part produced.
