Its been a while since I've posted any progress but work and home have got in the way a bit recently. The first of the kick boards have been fitted.

The remaining 'kick' boards have been made fitted and faired in ready for the stanchions to be fitted.




Next on the agenda is to finish the detailing of the interior.

A bit more of the interior detailing has been done.
Firstly the fire extinguishers have had their decals and fixing straps added.

The electrical boxes, trunking and wiring have added to the rear of the cabin also the first aid 'grab' bag has been made.

The first piece of electronic equipment that sits on the navigator's bench has been made and fitted in place.


Every time I look at pictures of the interior of the full size boat I see more things I want to add to my model so still loads of things to make and add. The list gets longer and longer.

The next item to be made for the interior is the radar unit.

The screen was made from grease proof paper with a green led as a back light. A few dots were drawn on the paper and when the led is turned on it looks like radar 'hits'. The radar screen will be wired so that when the radar arm rotates the screen will light up.

That green radar display is magic O0 ...[so magic we can even see the hits when the display is off %%  er...I mean the light is off]


Those red fire extinguishers are pretty good too :-))   ...certainly matches the fitout

Unfortunately I know you can just about see the hits when the light it off. I tried using pencil but you couldn't see them and I tried using thicker paper but the light wouldn't show through. So I went for a compromise as a blank screen was a bit boring.

Hi Derek I know it wasn't and I didn't take it as a criticism. Like I said I'm not 100% happy with it as you should only see the hits when it's turned on. The only reason I turned the lights off in the shed is they are that bright you couldn't see the effect with them on. Hopefully when the roof is on the cabin you will get the full effect.

Ok lets get silly here....how about a flicker light simulator effect,a lot of the railway lads use them in sheds and they are also used in dolls houses to simulate a real house fire effect or welding this would give you a flash on the screen to simulate a hit on the radar..........silly thought of the day

Hi Dave
I've actually found a circuit diagram that uses a 555 timer chip that fades the led in and out and using a miniature potentiometer you can alter the speed of the fade to match the sweep of the radar arm. The components only cost pennies so I might have a go at making one.

Looks great - You could have fun with a small oled screen - this is just an example

The main radio set has now been made. The front panel is a picture I found on the Internet and resized to suit. The handsets are taken from dolls house telephones.

All the main components for the cabin interior have now been made its just a case of sorting out all the little bits and pieces to finish it off.
