Sterling work Graeme and those vents look great - bet you're glad they're all finished eh?! Did you drill and file them individually or sand the whole area from behind until it was thinner and they opened up?
Looking good, well done.

I am now looking to run some interior lighting to the open compartments and will probably use optic fibre. I believe the engine room had only white lighting whereas other areas had red (or blue) to maintain night vision during "battle stations". I intend to put all the electrics in the base on which the sub will be mounted and run the fibres through the pedastals and into the sub. I really need to run the fibres into the open compartments before doing any more planking so will run more fibres than I think I'll need just in case . By using different coloured bulbs in the base I can choose what fibre displays the appropiate colour at a later date when I find out where the lights in each compartment should be situated  . I have ordered 0.5mm and 1mm optic fibre and should receive it next week. My next subscription parts are due tomorrow. Graeme

Hi Graeme,
That's a brilliant idea, It's something that this build is crying out for and I'm thinking of doing the same myself - (see my diary post #260, page 13) - but I hadn't mentioned anything about before as it's something I've never attempted before and wanted to work it all out before committing myself.
I think it will make a world of difference to your finished model, and lends itself well to this sort of model.
Like you said,it definitely needs to be installed before any more cladding goes on to the build - or at least getting the wiring/FOC's into place ready for when the compartments go in; speaking of which, how are you doing with the front end conversion?
Definitely the way to go in my humble opinion.
Happy building
David

Hi david, I've not done anything else with the torpedo room as yet as i was waiting to get as much strength in the hull before cutting any of the bulkheads. I am going to try and see how the fit for length, height and depth look and if it seems ok I may clad the port side (at the appropriate time) before fitting the conversion. I will also have to try and find out the correct placement of the lights so the locations can be drilled and suitable fittings made before installation.

Thanks for the comments. Just received some of the fibre optic stuff I ordered. A kit comprising a battery box, 3 clear LED's, heat shrink and 4 different diameters of fibre cable. I also got a pack of red LED's and some clear plastic rod which I hope to make the light bulbs out of. I have additional optic fibre on order and am looking for some suitable tubing to run the fibres through into the top of each compartment so I can run the fibres after cladding but before the internal structure are put in place. I know I've got some small diameter compressed air tubing inthe loft somewhere but I'm dammed if I can find it  . The other option is to source some of the tubing used in radio control planes to run the control lines through. Graeme pemberg attached the following image(s):

Hi Graeme,
Look forward to seeing how you get on. The kit looks great. I have seen this on their website, but I'm still looking around at the moment to see what else is available out there before committing.
Happy building

I have just been reading through the torpedo room installation procedure again and it definitely needs to installed before the bow is clad as some parts need to be fitted from the back (port side).
I am going to have to start preparing the resin parts and cutting out the bow bulkheads to test fit the parts - the point of no return.

Nice lighting kit you have there , just an idea but will drinking straws from Macky-D's say as there big tubes do the trick for the cable runs. Although I agree taking out the bulkheads will weaken the structure but when the resin is fixed in position it should strengthen it in this area and perhaps it will be stronger than before.

Well I received my next 4 issues yesterday, the first 3 contain planks for cladding the hull and the 4th has the floors for the engine room and control room. Before starting this part of the build I will have to install the guide tubing for the fibre optic lighting. The tubing I have have is approx 3mm ID and I can get 4 1mm diameter fibres through it or obviously more smaller diameter ones etc. I plan on fitting one through the enclosed compartment just astern of the torpedo room and 2 in the compartment between the control room and the engine room, one tube running to each. Each tube will run through the keel and then through the top of the port side of the bulkheads as close to the top of the frame as possible and I will finish them flush with the inside of the bulkhead in each of the open compartments. On examining the ceiling part of the torpedo room enhancement (pic below) there are 2 light fittings moulded into the part. I plan on removing these and replacing them with my custom lights. I was thinking of making one red and one white but then thought I could make the light source switchable and then each light could be lit either red or white - not strictly accurate but a compromise. The engine room will only have white lighting and the control room both but I can only decided where the lights will go once we receive the internal parts for these areas. Well that's it for now, I will post pics as I progress. Graeme pemberg attached the following image(s):

Nice going Graeme.
Is it my understanding that you'll be installing tubes into the hull rather like electrical conduit, which you will run your FOC's later on? That sounds like a great idea and it will keep all the 'runs' nice and neat.
Like the idea of the switchable lighting.
Do you think it's possible to get 'bulkhead' light fittings at our scale (I've been looking around and I haven't found any as yet) to replace the ceiling light mouldings in the compartments to give the light source a more authentic look?
Have you given any thought to making the navigation lights on the conning tower working as well?
It's giving me lots of inspiration to be following your build. Well done!!
Happy building
David

Hi David, I've not seen any commercial bulkhead lights at this scale (not sure if the torpedo room had any).
I had been thinking of navigation/search lights and if the conning tower is fitted before the control room interior then it may be possible to run fibre up to the tower via the control room - may need to think about fitting an extra piece of trunking in case - or running finer fibres. It will depend on how many lights are needed in the control room and the order of assembly.
I really need to watch 'Das boot' again to see if i can get a better idea of where the lights are located. It is difficult to tell in the walk around views on the dvd I got as the U-boat appears to have been fitted out with additional lighting for public tours.
As always more research needed and it will most likely come down to a compromise between what was actually there and what is possible in the space available.

So I took the plunge last night and started to remove the bulkheads for the torpedo room enhancement. After removing the aft 3 sections I noticed there was some lateral movement of the bow section - loss of rigidity. On investigation I saw that the longitudinal supports (parts 84 and 106) were approx 2mm short of meeting the aft bulkhead so allowing some movement. To stabilise this (until I could plank the port side) I put the hull back in its building clamps and cut a small piece of mdf from an old part fret and glued it to the bulkhead, part 84 and the central longitudinal frame. I then left it to dry overnight. This morning I removed the clamps and then the hull from the board and everything was rigid again. I then finished removing the bulkhead parts and sanded them level. I did this before fitting my fibre guide tubes so I can check the fit of the resin parts and see the best place to run the guide tubes. I was also looking at the enhancement fitting instructions I had downloaded from the forum at Marinemodellwerft_de and found that there were no instructions for the ceiling parts. On trying to go back to the site I found the forum had gone so I will have to 'play it by ear'. I did notice in the shop, however, that they now have 3 resin figures for the build.

Well done Graeme, good thinking putting that strengthener in. it's a bit of a pain not to have the instructions for fitting the resin parts. There's another guy on a German forum whose pictures are quite informative but you'll have to translate the text in Google or something. http://www.der-lustige-modellba...-u-96-von-hachette-amatiHappy building David

Started watching 'das boot' again as a reference guide (and not just a film) and there is a part approx 20 minutes in where a war correspondant is given a tour of the boat soon after leaving port and the scenes show the lighting quite well.
There are numerous white lights throughout the boat, with red and blue ones in all compartments except the engine room which had no red. All seem to be ceiling mounted, running either side of the centre line in the engine room and scattered in various locations in the rest of the boat. I believe the blue lights were used to show when the boat was running 'silent'.
I am now thinking of running more finer fibres if I can come up with a suitable 'bulb' design. I don't want to end up with pin pricks of light from fibre ends. I have a couple of ideas but need to run some tests first.
Again a lot will depend on the fittings provided in the kit as to what is possible.

Well I have been doing some tests on the fibre optic lighting. I made a couple of 'bulbs' from 2mm diameter clear plastic rod and drilled a 0.5mm hole in the back of one and a 1mm hole in the other to take the fibre, pic.1. I built a simple jig to connect the led's to the fibre ends and gave them a try, pic 2. The 0.5mm fibre doesn't put enough light through to give a noticeable effect, pic 3. The 1mm fibre isn't too bad - difficult to photograph in daylight but seem quite effective in reduced light, pic.4. However, as I am hoping to to show all three 3 coloured lights (white, red and blue) where appropriate and I can only get 4 1mm fibres through the guide tubes I will be using, the fibre lighting option is seeming less of an option. I am now looking at going back to using "grain of rice bulbs". These are 1.8mm diameter and so slightly smaller than my home made ones. I then came across another problem in that to have 3 different coloured lights in at least 1 compartment (control room) I would need to run 3 pairs of power cables to that area. I looked at using the inner cables from telephony cable but struggled to get 2 pairs through the guide tube. I then thought of trying enameled copper wire like that used to wrap motor armatures. I had some which is only 0.35mm diameter meaning I could get 5+ pairs through the tube into each area. The reason I want to run the cables/fibres through guide tubes is so that I only need to run the cables later in the build (with the exception of the torpedo room) so I don't have lengths of wire/fibre getting in the way during cladding the hull as I am bound to end up damaging one at a point in the build where I can't replace it. I have ordered some grain of rice bulbs so I can see how effective they are, but as I now know I can feed enough power cables if required I will fit the guide tubes as I intended and continue cladding the hull.
