Progress on the door mould has moved on, but not particularly successfully. The post curing of the main door and skin moulds worked very well in the new oven as I was able to control the heat ramp/soak cycle very accurately.
However, the problem became apparent when I attempted to remove the mould from the buck. Although it had been sprayed with gloss paint and had many layers of release agent applied, it didn't want to let go of the mould.
It took me an hour of cursing and sweating before I managed to persuade the mould off of the buck but not without some collateral damage to both parts. A lot of paint transferred to the mould despite the release agent and some of the filler used to smooth out the buck has stuck to the mould, one of the reasons for the difficulty in separating mould from buck.
However, main reason was me trying to make the main mould in one piece. Technically, there were no mechanical locks but in reality there were. I had to resort to cutting the corners so as to allow the mould to eventually release (easy enough to repair)
I had used a little vacuum to help the fibreglass take the shape of the buck, but part of the buck split under the vacuum, but it should not be too difficult to repair the mould.
Not my best effort, but recoverable. The door skin mould is fine and only needs minimal fettling, so that is something.
