Each plate was cut with an overlap on two sides as we worked our way along the bottom of the hull. These were then glued in with cyano  which dried 'very' quick so accuracy was the thing as there was no second chance.

The next line then overlapped the plate above, showing a ridge in the correct position on it's side and bottom edges.

One week later and 11 sheets of 1.2mm plastic later we finally came to the end. Thanks to Marks Model Bits for the plastic sheets. (did you know he sells the stuff now ?)

There are over 120 plates of the stuff on her now and she looks the 'Biz'

Just need to go around the edges to smooth her out and then we are ready to make our first Fibreglass hull.

Today we plated the upper section to the railings.

Then we needed a strip along the top so have cut out a strip of plastic 2mm square from an old window sill and positioned it to see what it looks like. There has to be gentle curve when finished running from Bow to stern to match the lower strake.

Looking good, Ken. I'll be following this build with great interest.

Thank you Peter. 25 days into the build of the plug and we are up to preparation for moulding.  %)

I have sprayed the hull by using up three tins of nearly empty spray paint (various colours) and started sanding the surface smooth.  It's quite difficult with plated plastic as the edges catch on the sand paper and either break of of bend back.  The problems are going on and on.

Today I shall final coat it with black as, the fibreglass will be lighter and show up during manufacture.  I have made a sturdy frame to go over the up turned hull to divide the halves and plan to 'glass' one side first.  My only worry is that the plating might be pulled off when the fibre glass is dry.    ;)

Here's the latest pictures.

Thank you Dan.  She is scaled at  1:35 and is about 40 inches long, so quite a largish vessel. The holes have been marked out along the top but could not be opened up as it makes the fibre glassing difficult, if not impossible. 

I rather like the present colour scheme as she looks rusty and worn.   {-)

  The plan is to make some in Rust colour and see how they turn out.  This plug is strong enough to stand on.     8)

Sprayed the hull Satin black today and noticed more blemishes.   %)  A bit more filling and sanding methinks.

I have made the frame to go around it, as mentioned earlier and have now sprayed it to seal the wood ready for the release agent.

Here's what the set up will look like. The idea is to glass one side of the boat up on the wood surround. When it's set the wood will be removed and hopefully the hull will come away from the glass covering. Then we will be refitting the fibre glass half and moulding the other side of the hull to match.  
                            (what can possibly go wrong   %) )

Thanks John.  I'm looking forward to mould making time as well.  Still on the blemishes at the moment. Another day rubbing down with wet'n'dry. Gave her another coat of paint tonight, so see how it looks in the morning.

Hi George, thank you for your kind comments.  I now post my prelude to the sadness that follows.

In my search for perfection I was not pleased with the finish on the plates so have been trying my best to perfect the blemishes. Unfortunately I didn't know when to stop and have been trying all different ways to iron out the flaws that were spoiling the build.

Sheets of wet'n'dry sandpaper later, I went for the respray with a change of colour. It would have been red oxide as a base again but someone in the store changed the tops of the can around and I got Renault Red in the tin.   %)

New blemishes appeared as pits and holes so it was out with the filler and top up the dents. These were sanded smooth and another coat of paint was laid.  The costs for this boat so far were "added up" while the paint was drying and it comes to  122  so far,    yes indeedy    >>:-(     I tried explaining to my good lady but it's falling on deaf ears.

The following day shows the results in red.  As a finally to this exercise, I used up two tins of black in the hope that it would smooth out the defects  ---  but it got worse.

All work has now stopped as it will need re plating totally, but this time with thicker plasticard.  I have been using 0.2mm and will probably go up to 0.75mm.

I can see where the costs go now when building a hull mould. I have priced up the epoxy/ gellcoat/fibreglass and it's going through the roof, so time to call a halt on the project.  I will probably carve out the insides and just continue as a 'one off' scratch build  (if I can find the motivation to get back on it)   :((.

Let the pictures do the talking  .....

Thanks John. I've slept on the problem and will continue with further ideas. I'm going for thicker plates and no paint spraying next time.

Onwards -------

Ken have you tried heating up your plates to get them to lay flat on the curves ?

Cheers Dicky. The new plastic will be thicker, so that's the way to go.

I have sanded it all off and placed my order for some 0.75mm. While waiting, I thought I might get on with the cabin structures.

Hi Ken sorry about your problems I personally don't like plasticard and always use 120gsm paper for my plating and use PVA to stick it and seal it. it is just like wallpapering  :} :}

Well that does look tidy. What a smashing job you've made there.   :-))

I've never heard of this method before. I shall remember it when mine goes wrong again.  %)

Thank you

Well I've ground it all orf again.     %)

Change of plan now as I'm going to plate her with very thin plywood, cut to shapes. The plastic route would not have stood up to covering with epoxy resin. I have the plywood and I think I know what to do by now.  :}   (third time lucky maybe)

The idea now is Not to make a mould but to continue making just the one vessel. I shall have to cut out all the sturdy timber inside the hull, but I'll do this when the extra layer of wood is glued outside to hold it all together.

Today I started on the cabins and have produced a frame which will be covered with plasticard. The reason it's plastic is because there are severe curves in the cabin front which could not be fabricated from wood.  Here's a picture of the frame under severe load for the night while the glue is drying.

Hi Ken don't forget that the top and bottom of the main casing follows the sheer of the main deck and should be curved to suit.
