Small update: It doesn’t look like much, but managed a good couple of hours last night on the hatch last night. Think I've broken the back of the work to get the mold up to where I want to be.

Bonded the tray together
Bonded tray to hatch
Fillered the tray and rough sanded
Filler primered the sounder, sanded the highs – repeat
Epoxy filled the previous screw holes

Sounder mount is good for a top coat and wet sand,
The filler work in the tray needs to be sanded a bit more to tidy up and blend around the corners, then the hatch lid and tray can be filler primed and sanded to the same standard at the sounder mount

It’s looking good! Any plans for a lid on the tray or will you just leave it open?

Yes I'm thinking a bit of a lid with similar mechanism to the original hatch - hence the 10mm gap between the sounder and tray :evilgrin:

I wont be aiming for watertight just something to hopefully deflect most waterspray. The lid will be simply secured with a quick release bungee similar to the aftermarket ones you can already buy for the standard hatch. I'm currently tossing up whether to make the lid slightly domed (read more effort) to increase the storage volume - obviously without interfering with vision and reaching of the sounder.

Thanks Frank.

I managed to get both bits sanded to 240 grit and I'm pretty happy with how it's turned out.

I'm hoping to nip off work early on Tuesday to pop to a composite place that's been recommended to me. Want to chat to them about best ways to make the mold and what they'd suggest to use as top coat to make sure no reactions to the resin etc.

Still have to sort out the lid, but will think about this over the coming days

Coming along nicely Nath.
In the bottom of the tray I'd add as much of a fillet as you can get away with, don't have corners you don't need its just another place for an air gap to form.
To make the mold you'll just need some tooling gelcoat, tooling resin and some 450csm.
Before you get to that you'll need to cover everything with about 15 coats of mold release wax.

There is a slight fillet along the edges of the bottom and significantly larger fllet in the corners. It did cross my mind about making the fillets larger along the sides of the tray bottom for the exact reason of air gaps, but came to the conclusion that I wouldnt have an issue getting the gelcoat into the corners for the mold. And when I actually coming to laying the carbon for the part, this "bottom" will be a top" in the mold - if that makes sense?

I've got the part with me, so will ask the "pro's" at the shop what they think :)

As well as the 450 chop strand I may also go for a something a bit lighter for the first layer to avoid any print though. What do you think?

Also Eoin, while i've got you ;), is there a reason why the hatch lid is so thick? Is seems excessively thick given its not a structural part. Is it because the carbon lid 100% carbon?
