Thanks Kevin.

Finally got around to finishing up that little island thingy on the upper hull that was causing so much grief so one is a rather happy bunny the noo!

It only took the better part of a week so here's hoping the other 1500 or so holes don't try to spoil the party.

Work has once again entailed poking a 0.5mm drill into the wee hole to clear out any accumulated paint to allow the FO strand to pass through easily or at least that's the plan. About 80% of the holes just won't allow the strand through so it entailed a lot of tedious work with a pair of tweezers gripping one end of the strand an literally forcing it through the hole until it either suddenly just slides easily through or else enough of the strand is seen on the other side so it can be gripped and pulled through. Either method works but like I said gets very tedious very quickly although the end result is worth it.

Because I started off on one side of the island a mistake was to epoxy those strands into place, wait 'til it cured and move on. The epoxy runs (rather like thick treacle) so whilst it cures it moves and some of the holes get covered so when it comes round to putting some FO in them I have to drill through cured epoxy as well and that stuff is a sod once cured and many a drill bit has met it's match in that stuff. Plan B was to put all the FO's in place and epoxy them en masse which had it's own problem as the strands kept falling out so I quickly decided to tape them down onto the hull as I went along.

This shows the first FO strands after being epoxied into place after the previous repair work on the island hump thingy.



And moving along - as I went round the island I just put done some masking tape/painters tape on the model to save it from being scratched if the drill bits slipped which they did regularly.



Once all the strands were in and epoxied into place I just gathered them up, wrapped a small length of insulating tape around the ends and strapped on a cable tie to that to stop them ever coming apart. The FO strands were then cut off leaving about 1 inch sticking out which is where the led light would be glued into place.



Next item on the agenda was to apply some tulip paint to the light box at either end to cut down on excessive light leaks.



And after all that and about a weeks work this is were we are now. The FO's just need to be trimmed and we will have a voila moment.




I hope you like what you see so far. Later on today I will start work on the main superstructure lighting and about 800 holes.:-X

Sanity is rapidly waining. :o

How do you plan to mate up the LED with the bundle of fiber?

Work has continued on the model and I have started the windows on the main "island" superstructure on the upper hull and it is here that I came up against a problem (more annoying than problematic TBH) and my wee brain came up with a solution. More of that later.

As usual the FO work has entailed threading the strands through the pre-drilled holes and once a section had been completed - applying some epoxy and moving onto the next section.






Learning from a previous boo-boo I finished the section I was working on before applying the epoxy. I also have not attached the required led as it would just get in the way as I carry on with the FO work. With the attached leds it is like bending a piece of wire back and forth and it will eventually break so I have to be careful with those leds that are already in place. Once all the FO work on the upper hull is completed I will of course attach all the required leds.

On the inside I have just trimmed the FO strands leaving about an inch to play with and once again I have tied the strands up (about 50 in each bundle) with a short length of insulating tape and then secured the whole lot with a cable tie.



Next item on the agenda was to trim off all the excess FO on the outside with a new hobby knife blade ('til the tip broke) and I will no doubt spend months clearing up all the little FO pieces from the carpet once this build is finished.




I just need to touch up some little areas where the paint was scratched and TBH you would'nt notice even if I pointed it out but I know they are there.

Now! As I have'nt got the leds mounted the next two pics are just the model held up to my work light and so far so good methinks.




Working on thsi section took two days as once again the FO strands decided to play silly buggers and really got annoying very fast as some FO got bent and wasted even though they are the same diameter as the holes I have been putting them into. I still have over 1000 holes to put FO into so this is going to take forever and a day so I have ordered up some 0.55mm drill bits to open up the pre-drilled holes and hopefully that extra 0.05mm of the drill bit will allow the FO strands into the holes a lot easier but I won't know for sure 'til the bits arrive later on this week. If my idea does work I will get all the windows done in record time and can then concentrating on any necessary touch up work. I will keep you posted as to how it goes.

As always thanks for all your comments and I hope that you like what you see so far.

Man, that is a lot of fiber optic strands! Looks good!

I found videos of a guy that used the same technique as you on the preshading and using the pencil lines!

Thanks guys.

Scott - the bundles of FO's will be slipped into a 6mm brass tube which has a 5mm led glued to one end and the light will get transmitted along the fibers.

ASF - It was Ant of Bashing Kits/You Tube where I got the idea from and he was extremely helpful with the painting.

Roger.  I used straws.  Love to see the different ways the problem is attacked!

I'm glad you are enjoying the build Nick.

Just when you thought it was safe to look at this post again. Been a few days since my last update and although some problems still remain I thought I had better get some work done on the big girl or she will never get finished.

I hope you don't mind endless pics of FO strands being threaded through wee holes which is basically what I will be doing for the next month but work is speeding along nicely now thanks to an idea I had about the drill bits/holes.

As I have said the original holes for the FO strands were made using a 0.5mm drill bit which was fair enough until the time came to thread the 0.5mm FO through those holes and many sweary words and extreme expletives were uttred as the FO just would not go through despite me using the 0.5 drill bits to clean out the holes of accumulated paint. The easy solution was to get 0.55mm drill bits and use them to clear out the holes and it has worked like a charm. The only problem is that sometimes the FO strands fall right through the holes now but it is so much easier now and my solution to that was to tape down every 10 fibers or thereabouts so they did'nt slip through but that is a minor inconvenience to the old way which resulted in many strands getting bent and generally thrown away when they were ruined after trying to get through the original holes.

The next pic shows the 0.55mm bit on the left and the 0.5 on the right.



And the beginning of the FO strands in the main centre island of the upper hull.



Whilst I tried to make life easier for myself the switch I ordered from China arrived. I just ordered one to begin with as I wanted to have a look at how long it was (that would determine the eventual thickness of the oak display base) and whether it would be suitable for this build in general and I think it is.



The locking nut just under the black o-ring will be removed when the time comes to mount the switch. I have ordered another and one switch will light up the windows/docking bay and the second will fire up the eight engines.

Going to have to order up another 300 ft of FO soon as work is going so well I am rapidly running low on the original 300 ft I bought before starting this build. I will also have to get the finger out and start to get some more leds ready to be installed as I reckon this build will now need about 40 all in and that's not counting the 0805 smd'd I will use to light up the main docking bay.

Talking of which I can't seem to find any good shots of the smaller docking bay just to see if that is lit and how to go about it. If it is lit I think I will have touse some more FO as it is just too small for any leds/smd's but I will figure something out nearer the time.

Thanks for watching and I should have some more updates soon.

ps:- And thanks for the kind words since my last update - very much appreciated as were the pm's.

Have you had your fiber today?

We are slowly but surely getting there with this build (just as well as my sanity is going down the pan with all these FO strands).

I have just about completed the main centre island windows with only about 100 to go and they will be finished today and then I'll start getting the leds installed and hopefully the bridge module as well.

Still got some trimming to do with some of the strands but here we are with the kit held up to the bench light.



And with some trimming work done.



The rest of the time has been installing the rest of the strands and I think the count was around the 800 mark. It has been extremely fiddly at times as once I had the strands threaded through the wee holes a lot of the fibers were caught up in those that were already installed and it was a total pain trying to suss out which one was which until I hit on the idea of using some painters tape to cover up the already installed fibers so the new did'nt get tangled up (no pics though) and that worked a treat.




Nearly there.



That's it for this quick update but as I said I should have the centre island finished up today so I need to get some more leds soldered up and ready to go and my initial estimate on how many I will need has totally gone out the window. Will make a nice change to installing FO's for a bit.

Thanks for watching.

Hey Iain ...what do you use to glue your FO in place? I use gorilla glue epoxy but that can get a bit wasteful because I always squeeze out too  much.
  Looking great by the way. Again, your patience is off the charts.  ;)

Thanks again Kevin.

I use 5min epoxy to secure all the FO's in place.

So the epoxy does goof with the FO?  Sweet!  Any idea how many 'holes' you will have drilled when you are done?

Hi S/M

I gave up counting at 1600 holes TBH as my wee brain was about to explode but I think the final count is a smidgen short of 1800 all in.

I need to order up some more FO as I have used up my stock (150mtrs) just on the upper hull and bridge. Can't see the lower taking up that much but whatever I have left will be used on other projects I have in mind.

Once this build is finished I fully intend to take a break from modelling until after Christmas to catch up on some reading and Xbox One time.
