I'll try to get some video tomorrow. To be really honest, the Arduino is overkill for this function, but I wanted to try to understand them, and my problem is finding a use for these things. I spent my life working in IT, but unless someone gave me a problem to solve, I could never think what to do with it Very Happy.
Let me know if you want the code.

Ha like me I like to find a problem that's not there and try and fix it with something that I know nothing about. 
Yer wouldn't mind the code just so I know where to start really.
Thanks Barrie

I've sent you the code as a Personal Message. The video wasn't very good so it is no point loading here.

The cable is plastic covered bowden cable running in the outer from a 'snake' as used in model aircraft. I have some cable if you want it.

Thanks Barry. Really struggling getting the ramp how I won't it to go. 
Quite tricky with the extra ramp as well. Where did you get it from ?

Came from ebay I think, but a bike brake cable would do the job. I found that you need a powerful servo - a standard one wasn't strong enough, and you have more weight to shift. To get the flap to drop you need the fixing for the end of the cable to be on the flap. I'll try to draw a sketch if you wish. 
The other thing I found was that the servo arm had to be stiff to prevent it distorting. The one with my heavy duty servo is OK, otherwise you can get metal ones.

Hi Barrie 
I got the bits from eBay but its the wrong size cable its like 2 mm 
 So will go and get a brake cable I think. 
I think I sorted how to do the top ramp just waiting for some platisc five for hinges

Hi Barrie 
Just ordered for my next build a 1/32 scale of this ferry. It's a fibre glass hull and plans. Will be asking you for help on the building of it especially the ramp mechanism 
Cheers lan

Is this the one from Skelmersdale? (used to live there Mad) I hope the hull shape is better than mine or it won't go in reverse!

Yes that's the one Barrie . Small little lock up. The stern where the prop shaft come out doesn't look as square as your. The Bow and stern look the same angle. He said he's seen a few made up one with a drop down ram like yours and a remote truck on board. 
 
nhp651 has a nice photo of the prop shafts on the Raasay on his MV eigg build Was thinking of trying this. What are your thoughts

I think the trick is probably to make sure that at least part of the props are below the hull. I have had an idea for modifying mine - I may get round to it sometime. For the ramp you need a powerful servo and some bowden cable.

There is a build log of a double size Rhum on the Mayhem website - it was started on here, but the photos have vanished. Mark used a different approach to making the ramp operate, but he did have more space to play with Wink
When you get round to that I can give you some more details if you wish.

Thanks that would be really helpful. Should be picking the hull up Friday all being well.
