I never thought of that  :-)) 
However I'd rather switch it above the batteries under the superstructure
I think any hatch that isn't screwed down and sealed it bound to let water in

At this stage I considered using 3mm paxolin for the main hatch too but I'm sticking to my plan.

Here I think you can see my intention. The deck around the hatch will be doubled up. I thought it was 3mm ply (according to MMM) but it is 1/8th as two are more than 6mm.
So here the shelf will be wider and I'll be using M4 countersunk SS 8 off. Only need access for maintenance{oiling} or repairs
The difference in thickness will be made up with a self adhesive foam strip that will act as a seal too.
The deck is still dry fitted while I am sealing and sanding the ply, first coat on and sanded here.


Also you might have noticed I've omitted the motor connectors as they will not be accessible with decks on.

Hmm deck fixing. My last two builds I have used Gorilla glue. Its an epoxy foaming glue, wet one side of join, apply glue to the other and hold/clamp in place while set. It is totally waterproof when set. You just have to be careful how you apply it, as it is a foaming glue it does bubble out of the join edges if too much is used meaning cleanup work has to be done. But I've found if you let it semi set, then this can be peeled off, if it sets completely it can be a b***h.

Thank you Brian. I think its going to be a little messy whatever  :((   I think I'm going to stick with (no pun intended) Z poxy as so far the 5 & 15 minute mixes have been spot on. The 30 min should be enough as my rear deck is in two halves.
The little problem I have is to align the first piece I have to fit even if loosely the Kort hatches. In hind sight I'd have been wiser to drill and tap the shelves later .  Live n learn  {-)


I'm just applying chemical metal below the bulwarks this morning while the house is empty. Influenced by Stavros thanks Dave

Thought I may as well crack on in tandem with the superstructure.
I've concluded that I did not get anywhere near enough 1/8th ply with this kit.
With all the paxolin I've used in its place you'd think I'd have loads spare, Battery mounts/ Motor mounts/Hatches and shelves. Perhaps I didn't receive the correct amount? it says 5ft but I only recall two 2ft sheets

Revision

Model shop
30 min resin
1/8th plywood sheet
Long servo arm
Admiral putty white
Zap a gap
Styrene sheet 2mm? For bulwark frames/ribs watsits
Humbrol paints for deck fittings

I need the longer servo arm because I've set the servo to 150% travel but it's now limited mechanically
A longer arm will give full travel and crank back the percentage

I'm satisfied with MMM's winches. As it says some fettling needed but results are very good for the money  :-))


I needed many more washers than the 2 supplied to take up the slack though.


Can anyone give me a specific colour of the dark blue used on sveitzer ? spelling

Thought I'd never get there but finally on with the foredeck. Going to be pretty solid I think  {-)

They need to be solid Andy  :-))  especially as your planning to do some towing, I normally use 9mm ply for the decks and bolt the winches on.

I'm going to put a few more stringers over the motors where the winch goes and the lead will be fixed on the 6mm paxolin hatch  :-))

Andy, you've seen my Ormesby Cross. 


It is painted with Halfords rattle cans.  The blue is Renault Royal blue. 


I think it looks right.  The cream is subject to more debate.

Got the last two tins  {-)  apparently they're bringing out a new range next week onwards so not been restocking recently


The colour band on the can lids is very inaccurate but as you get 1 in four tins free I bought a Rover Arun white to test out.

Well full of trepidation and a couple of strong lagers I decided to dive in with gluing the foredeck rather than risk the rear deck without experience.
It has gone well and the resin did go off in 30 mins  :-))


I previously added more supports and reinforcement for the lead.
Here you can see how the resin applied to both surfaces has filled the gaps nicely



Knowing this is a runny mess I exercised damage limitation with kitchen roll beneath. Some of this has stuck but out of sight.









The ply had 3 coats of sanding sealer before the grain was filled.
