Hi guys, .......need some assistance please. Have been busy this week fairing the hull and thought i was ready to start planking.
Narrowed the false keel to 2mm as per instructions, and i now realise that the ribs dont fall flush with the bottom of the false keel. The distance between the bottom of the ribs and the bottom edge of the keel varies between 4mm and 7mm on individual ribs. Has anyone experienced this or am i being thick again. If i aint, i cant understnd why with ' laser precision ' i have so much to sand off. I envisage a problem of maintaining a straight edge along the bottom and achieving a flush contact with the ribs.Hope i have made my predicament clear. Opinions, suggestions and advice all gratefully accepted . Confused

AFAIK the ribs up to 26 should be flush with the bottom of the keel with 27, 28 and 29 rising to form the correct shape for the stern. It was the ribs at the bow that I had to pack out the most to meet the keel.

I have been patiently awaiting a response from DAG about the quality of the laser cutting almost from when I joined the forum. I have every confidence that they will be polite enough to answer my question at some stage, when they are ready.

Thanx for looking guys. I have looked at my model closer now and think i may have spotted what has happened, but dont quite know why.
Looking through the model from the side, there is a gap between the lower deck and the top of the false keel which roughly looks equivalent to the excess at the bottom of the keel. However, there is no gap between the deck and false keel at the bow and stern between the last two frames,?
This leads me to think that i have not pushed the ribs down enough when attaching them to the false keel in the first place, but i'm sure i interlocked them as far as they would go. But looking at the pics in the magazine, and i'm sure you will confirm this, the lower deck should sit along the top of the false keel the full length of the ship. Looks like i have made a very basic error and boy do i feel like an idiot.
I dont know how to post pics, but will find out and put a couple on so that you can see what i am trying to say.
Whatever the cause, the problem needs solving one way or the other, i certainly dont want to abandon the project at the first hurdle, self made or not. I just cant believe i may have been that thick!!!
Also, i would like to apologise to Deagostini as it would appear that this may indeed be a problem of my own making and not theirs.

I must be a glutton for punishment, I have started subscribing to the Endeavour ship build, to be collected whilst doing the Victory and started next year.

Please ignore pics other than 2,6,7 & 8, they show what i mean the most. As i said, the deck meets the top of the false keel between 11A & 13 at the front and 29 & 30 at the rear. these two points are higher than the rest of the keel top if you understand what i mean......... apologies if explanantion is a bit sketchy.
I could sand the excess bottom off when i have planked all the way down eventually i suppose, but will there be a problem when the actual keel is fitted to that?

Some pic would make it absolutely clear. Have a look here.

As for being thick, don't worry about it, at the price we are paying for this ship I can be as thick as I like otherwise why else would I have done this?

You're right Dave, you haven't pushed the frames down far enough onto the false keel. When they are properly seated the tops of the frames will be flush with the top of the false keel.

I'm afraid you definitely need to prise the model apart and reseat the frames. You may need to sand to the slots a little if they were too tight to go fully home. You will have all sorts of problems if you try to push on and sand the bottom of the keel.

Good luck
Mark

if you do need to take it apart and you have only used wood glue, all you need to do is run the joints under warm water and wiggle it gently the glue will weaken and come apart easily

Well....... think it may be sorted without too much damage.
I took the deck beams from the middle deck by using a scalpel to free them from the deck and removed them with gentle persuasion and lots of prayers... and all this at 1130pm last night. Having done that i ran the scalpel betwen the deck support ribs and the shoulders on each frame, thereby releasing the deck edges. I eased the two deck halves up in the middle and cut through the deck supports which allowed me to lift the deck out in reverse of how it was installed.
This meant that i then had access to the lower deck, and using a block of wood and a toffee hammer i tapped the deck assembly down to meet the false keel, closing the gap. Eventually it sat on the false keel as it should have done in the first place. I then secured it in place with pins along the inner edges to the keel.
I have now cleaned up the decks and ordered some more 1.5mm x 4mm deck support strips and then i can replace the middle deck and the retained deck beams.
One of my worries was that the fairing that i had completed would be out, but i have checked that again and it hasnt made a significant difference at all really, thank goodness.
Thanks guys for your help and support, i anticipate that i will be a more regular user of this great forum in future. Cant wait to crack on now. Meanwhile i will finish the launch and start the cannon while i wait for the timber to arrive.Laugh

Glad you sorted it out, I had a similar problem with the gallery bits , I found I hadn't pushed them down far enough as well. I held the model and lowered it into a bowl of water, just enough to cover the rear, and luckily all the pieces came loose without too much damage.
Good luck with the rest of the build, I wish i'd come across the forum earlier
Come on you Jimmies

Glad it's sorted Dave. That sounded a lot less painful than it could have been.
