The balloon worked well and the shape looks good, a couple of small lips to worry about but the basic structure is good and strong.
The problem was I couldn't get it off the plenum - the electrical tape wasn't providing a good release and the 'green' resin was sticking very well. After more thought and taking some time / patience with a putty knife I did manage to extract it and remove all the tape. I decided not to add any additional glass today and let it cure further - I'll add a final layup tomorrow and then worry about microballoons on the inner surface for smoothing.
One down, one to go. Onto the RHS inlet, extracted the AL from the old PoP mould and drilled the upper and outboard locations.
Spent the rest of the afternoon making a new AL ring, some interesting bends and folds for the lower corner and normal templating / forming process for the front. Goes quicker second time around as I have some idea what I'm aiming at!
