Result! Looks excellent.

Very impressive. You're making it look easy, and the part looks amazing!

Thankfully, yes!!!

Crossed posts, part 3, it's usable 👍

Bugger.. 

Part 3... Does it all fall to bits out of the mould? With the consumables removed and the resulting mess cleaned up I removed the mould return flanges to separate the bonnet. The release was good and the edges of the part came away nicely it was just the usual pushing and shoving of wedges to break the vacuum of the large flat areas at which point the bonnet pops out with a literal bang. Remarkably all seems solid. The gelcoat is good aside from a couple of thin areas under some of the returned edges where I was struggling to get in with the spray gun and couldn't really see how I was doing either. But that isn't a disaster for a part that's going to be painted anyway. So I think I got away with it. Not exactly sure what happened with the vaccum. My only thought is that the bagging didn't like having the vac killed to fit the resin feed hoses. The film is slightly stretchy and copes pretty well but there may have been an area that got stretched a little too much . And I weighed it. In the end my resin calculation was a little over and I only needed a little over 5kg (including the stuff lost in the consumables). But there was of course almost 2kg of gelcoat. The wheel arches and the other reinforcing panels need to get bonded in still but for this bit.. Next job is to get everything trimmed and tidied before bonding it all together

Part 2... However when I went out the following morning to check on the cure I found this.. Overnight the bag had lost vacuum. Although it must have been very slow as there was still a lot of adhesion between the infusion mesh and the part. Question now what what was the part like, was it buggered and would I need to start again So peel off the consumables. It all rather bulks up. Underneath there are quite a lot of 'sunk' areas where it is clear the infusion mesh has lifted and the carbon isn't fully compacted. But overall it looks like everything got propely wetted out and perhaps partially cured before before the vacuum failed. If this was a structural part it would almost certainly be scrap due to insufficient compaction. But it's not so as long as there are no major voids and it's all bonded then maybe not. I had been planning on coating the inner surface of the bonnet to get rid of the surface dimpling from the peel ply prior to painting for cosmetic reasons. But need to see if it comes out of the mould first.

Wor! Look at that. Brill

Catch up time. Part one... The thick wall 9x6 mm hose I ordered off ebay arrived as 8x6mm. So that went back and I ordered the right stuff off Easy Composites, which I probably should have done from the start. Hose arrived, got fitted and the system vacuum leak tested again. Three resin feed lines to the resin bucket. Resin, mixing buckets and mixing schedule ready to go. Mixed the resin and started the feed All done. Just need to leave it for 24 hrs to cure  

Bit of a delay on doing this as been away as well as being unwell, finally ordered the Merlin hubs so will report back if they are any better. Also ordered one of the last bearing spacers to make that job better too off ebay.
