I was given a bare Seabex one hull by a member on here when I was building my scratchbuilt Hull version some time ago.
Sorry, but I cannot remember who. :embarrassed: Please make yourself known as I am now using it to make another Seabex one. (Seabex two ?)
I have to scratch build everything to go into the hull and I must say it's an enjoyable experience.
I have loaded the pictures into the Forum's system, so am on a steep learning curve for this next bit.
Here are some of the build pictures so far.

They are nice John, not too much cash for the engineering involved either. BUT it does say may not post to UK.
That is because the German postal system if pretty uptight about mailing stuff out of Germany. I am led to believe if anything goes missing in transit 'over the border' they are still responsible for the loss and replacement/refund. Many sellers in Germany tend to use couriers now, with the extra incurred costs - I know to my detriment! I got some parts from a shop around 39€ worth, the courier charge doubled the price. {:-{
-
cant comment on the quality of the product or what you get and still need.
As for postage . 99% of sellers that say they wont post to the UK will. They Dont charge alot ,worst I have ever had was 17 euros

Nice bit of gear Cos. :-))
I won't bother at this stage now as I'm committed to the old faithful way. I have filled in the Schottle drive holes and am going for twin props.
The ship is well progressed as I've been quietly (for me !!) working away by producing a build with just the stock I have in stores.
cheers

Moving on, here we have the hull being fitted out
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0793.jpg)
Having decided not to use Schottle drives we fitted a pair of 600 type motors

Jumping ahead a few weeks. :o :}
Here is the upper cabin lower secion, constructed from Plastic card along with the funnels and flight deck.
The stern section is also covered, but fitted out with easy access holes for 'underground work'
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0799.jpg)

-
Upper cabin completed, along with those angled windows. They are really fun to build. Even the second time I did them twice. {-)
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0814.jpg)
These took a while to cut out.
and No they won't be glazed. :}
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0815.jpg)
-
Moving to the stern I have made some fire hoses and fitted them on the top of the hollow frame. Pipes will be run underneath to supply the water.
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0823.jpg)
Guess what My wife bought for me in Poundland. How can they do it for the price.
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0824.jpg)
I then spent a few shillings at B&Q on some brass pipes and made the radio mast and radar supports. I shall be doing this again as the criss-cross supports should be thinner material and I didn't have any at the time.
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0826.jpg)
Unfortunately it has bee painted since this picture so it will all have to done again. (two days work with a blow lamp ahead !)

Here's a view of the painted aerial mast

here we went mad with the B & Q brass pipe. came out Ok though

The crane section is my favourite.
This was constructed from plastic card ALL hand cut from a large sheet and patiently glued together. I really enjoyed watching it all come together
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0840.jpg)
A close up
(http://modelboatmayhemimages.co.uk/images/2017/11/25/DSCF0842.jpg)
We are now up to date, so progress will appear slower from now on.
Miniature drive gear motors are on order so the crane is docked up waiting to be finished. Meanwhile I'm in the process of making 100 railing pillars (stanchions) by hammering 2mm brass tubes flat and drilling them two 1mm holes each. %)
If you think this is easy, then have a go. :}
cheers for now
ken
-
Another lovely build there Ken and as per usual I'll be watching this one progress too :-))
-
Going well Ken, snap with the stanchions.
I've made 36 this weekend, I cut strips of 0.25mm brass sheet into 4mm strips then drill 2 holes and a top notch for the cargo rails on my ship, still have another 40 to go. When I get to the handrails I need 280 stanchions with 3 holes and a top notch, these are only 2mm wide %% %% I'm seriously thinking about having a go at chemical etching these out of a sheet of brass rather than cutting them.
-
Lovey work Ken.
I like the crane muchly :-)) I thought you were zooming along until I saw you mention that this was a time lapse until now.
Still, you have got loads done.
-
It does all look very speedy. {-) Lovely comments fellas.
We are actually talking around a month at 7 days a week of around 5 hours a day, 7 days a week. Did I ever say I liked boat building. :} :}
Yesterday I built another giant mast as I wasn't too pleased with the heaviness of the previous version. Some mistakes were made in the thickness of the brass tube and, as it was sprayed, it was too late to unsolder !!
Pictures will follow when the finished one is done. Today I will be making more stanchions Brian. Yes they are tricky to do. I crush the 2mm tube flat and drill 1mm holes in them. Oh what fun watching it wander to the edge. :}
The secret seems to be getting the material dead flat and going very slow on the initial start hole to stop 'wandering' and then they come out Ok. The next problem is the 'wire going through them. I am on the look out for single strand at under 1mm diameter as twisted copper wire really doesn't go well. %)

Hi
In the pasts I have used 13amp earth wire, sorry but I do not know the size.
-
Oh my, this brings back memories, as I have built one of them beasts almost 30 years ago. It was great fun building and sailing in all its glorious functionality.
Great job so far! :-))
-
Make a jig for the drilling Ken. A piece of plywood with an L shaped piece glued to it, your stanchion goes in the crux of the L and is held steady. Make a plate out of thicker brass sheet, mark off your hole centres and drill through. This plate is then held on your stanchion with 'finger and thumb' clamp, then just drill through the plate, holes in the same place on every stanchion! Once holes are drilled, measure of length and trim before next one. ;)
Wire for the rails - look for rolls of jewellery or craft wire in places like the Range, ebay etc. comes in 10metre lenghts of varying thickness, get the half hard, the soft is too soft and hard is too hard O0 thicknesses go from 0.2mm 0.5mm 0.75mm and 1mm.
It will have taken up a curl from the rolls it is sold in, trim off a length say 15 inches or so, hold each end in pliers and waft through a low flame, this allows the pliers to pull it straight with light pressure and remove any curl or kinks - job done! Its what I use for all my handrails.
-
I like your ideas on the jig. It never occurred to me to place a pre drilled master above the part to be drilled. It would hold the tip of the drill stable much better. many thanks for this.
I shall wander down to the Range and have a browse at the wire you suggest.
cheers
ken
-
Well, I wandered over to the Range and found the wire suggested. It looks great and I look forward to fitting it when I've made another 50 or so stanchions.
Meanwhile I have used some of my stock of coffee sticks %) and made a few hundred planks. These are all sanded to shape and fitted to the rear deck and stained.
(http://modelboatmayhemimages.co.uk/images/2017/12/03/DSCF0845.jpg)
Here's a few close ups.
(http://modelboatmayhemimages.co.uk/images/2017/12/03/DSCF0846.jpg)
The 'lift off deck covers' have yet to sanded to fit tidy, but the overall effect is rather startling.
Here is the "new" radio mast made from thinner brass tube braces. It is yet to be painted but I think it looks better than the first version.

I have also made the rescue lifeboats
(http://modelboatmayhemimages.co.uk/images/2017/12/03/DSCF0847.jpg) (http://modelboatmayhemimages.co.uk/image/8ceAS)
These were made from solid timber and sanded to shape.
Just the launching ramps to figure out. ok2
-
I like the planks Ken and the mast looks great :-))
Nice boat.
-
On the crane, replace those ugly nuts and bolts. If you cut down a couple of half inch panel nails so you have the head and a short piece of shaft. Insert one at each side and a spot of superglue to hold in place, this will let the job still pivot but look more to scale.
-
Thanks Ian. I thought the planks looked like they were worn with use. :}
Four sections lift off for access to the innards. I haven't got any catches on them yet but I'm working on some large containers.
Good idea Brian. I'll work on it. I have fitted the stanchions and wired them with 0.6mm twisted picture frame wire and it came out great. Thanks for the construction tips.
I now know how to thread twisted multi-strand wire through 1mm holes. .... you solder the ends before trying to thread them through 60 holes. %%

Similar to melting the end of a new pull start cord with a lighter to harden it so you can thread it through the pulley hole.
-
Seems a bit of a shame as you have the seabex one you could not model the sister-ship: seacom / norskald before osprey before my time on her,Acergy then SS7!
one of threee series at "Chantilliers" th3 3rd sister never got built.
,...The ships are legendary back in the day for diving capacity.
...like I say -it would be nice to model a seacom /norskald / osprey: everyone seems to think of seabex instead.
-
Thank you for your input RST :-))
I've looked at the ships you mention (Google time!) and they are different in construction. I was stuck with the hull shape I had and considered alternatives but could find nothing that was similar so I went back to the Seabex design.
I suppose the variation would be in the deck furniture, so I'm placing stuff on board to fill her up.
Still working on them railings as new material stock has arrived so it's back to the work room for more tiny drilling. ok2
ken

Your Seabex seems to be missing the moonpool. Did the previous owner ommit this? (https://www.cosgan.de/images/smilie/konfus/a015.gif)
-
No Tafelsptz. It did come with a hole but I have filled it in. %)
The hull is plated over and smoothed to match the base. My reason is that at speed (so I have read !) the water would slurp up into the boat. I did have one on the first version but never launched it so cannot really comment on its performance.
Still making stanchions. :}
ken
-
I see. I never had this problem with mine, as far as I can remember, and I sailed her a lot. Ah well, makes yours all the more special :}
-
The captain wants to go surfing. {-)
I have also fitted twin props instead of schottles so normal driving ahead.

Hi Ken,
Nah-no worries. The hulls and superstructure were essentially the same at the beginning -think they had the same aft crane also as we used the original "tub" below decks as a rigging store (apart from the exposed moonpool(s)). It all went different afterwards, the sister had sponsons added later, the Seabex One was significantly modified (lengthened etc.) and is barely recognisable these days.
I take my hat off to you for modelling the Seabex anyway and I have hull plans but making from scratch would be allot of effort. Both ships were an absolutely awesome machine. Allot of guys I used to work with were on her and the Orelia.
Lots of azimuth propellors, some fixed speed -variable pitch, some variable speed, fixed pitch + tunnel thrusters the same. We had a fair few problems with motors burning out and loosing DP3 capacity. Great sea-handling boat though (too good-we stayed out when most newer boats went in for bad weather -total puke bucket for some project engineers!!). Pretty much the last to pull divers -stay in the field, first to put them back down.
Sorry -I'm reminiscing and digressed %)

...By the way, if you're looking at deck clutter. Hyperbaric welding and installation of spoolpieces was big back in the day.
If you look at early pictures of the back-deck on the web you might make out a mobilised spread which has a big white "habitat" and two "arch" shaped objects with big feet. The habitat might have been a one atmosphere set-up they welded pipe in. The "arches" were alignment clamps placed either sides. They would sit on the sea bed and "clamp" the pipe so it could be moved left-right-up-down for fit-up of the weld in the habitat. There would be a HUGE amount of deck containers, hydraulic powerpacks, air treatment and associated equipment to make this work. Lots and lots of reels of hydraulic pipe and smaller downlines. You could fill the deck almost totally with this kit (and I tried to fit it on the Osprey once for a tender) -you can't get away with it these days due to stretcher access, ventillation requirements, extra accomodation needed etc etc. For all the offshore service vessels I have seen modelled, I haven't seen many with a fully loaded deck so far. A good challenge for you perhaps LoL?
Rich
-
That's exactly the sort of clutter that I was looking for ...watch this space. ok2
Work has stopped for a while as I am building another single decker bus ( flat pack version) for a client. %) I really don't have time to scratch !! it's nice to be busy.

Hello!
I just now watched a Norwegian movie from -13, called "Pione'r" (Pioneer). It' s about North sea oil divers during the eighties and it' s quite good, being a thriler inspired by true event's . Anyhow, there are quite a lot of scenes containing "Seabex one" or sisters! Good for reference :-))
Hama
-
Gosh !! that's interesting Hama.
Two things I've noticed. There are double the lifeboats and a very 'cluttered' stern deck. I also notice the crane cabin is way up the centre section ? ( I've stuck mine on now)
I guess mine will have to look like no other. ;)
Cheers

...any chance of a weblink please as I'm facinated but not found a match.
If youre interested in this kind of history the following website may be of interest. Whilst I'm too young to have worked in the "pioneering days". I worked with lots of "old" guys who were "young" on all this sites photos and videos. I used to work with a guy who was on the original Hydrogen gas diving scheme and one who was on the panel on the deepest dive with Leo.
This link is well worth a good browse, It has an absolutely hoooooge amount of info, pics and videos buried in it.

If you google Seabex One you will find that she is now the Kreuz Installer, and currently in the Singapore area. She has been altered quite a bit and there are quite a few pictures of her.

I just did and am impressed with some details.
I've started back on 'them railings' today as new 2mm pipe has arrived. I'll let you know the total stanchions when I've finished. :}

...Presumably still the "Venturer" in a different name again. It's interesting how long the old boats keep working, they're often better in heavy seas than the replacements so "flagships" come and go but sometimes the older boats are still "last-in first out" in heavy weather LoL.
-
Never come across the info before but apparently she was the "Dynamic Constructor" before CSO days. I quite like the blue / black paint scheme...
(http://www.shipspotting.com/photos/middle/4/7/1/2346174.jpg)
-
Is that a white boot topping or a lot of rime along the hull? That would be some weathering to recreate.
-
My goodness. That's weathering to the extreme. :}
Works is continuing at a slow pace so no pictures yet. I need to paint a bit to be able to continue, but the weather is bit cold at the Mo !
Cheers
ken
-
The workshop was all warmed up and paint spraying continued with masks and breathing equipment. {-)
I have sprayed the upper decks a lovely shade of green. Now where can I get some large circles in white. ?
(http://modelboatmayhemimages.co.uk/images/2018/01/06/DSCF0886.jpg)
The stanchions are temporarily hammered in (square peg in a round hole !) and the picture frame wire run through the holes.
What is recommended here, chaps. ? Pull taught and superglue !
We then had to remove the funnels for paint and started with the red colour. When this is dry, we will put some 'bands of colour' around the tops.
(http://modelboatmayhemimages.co.uk/images/2018/01/06/DSCF0887.jpg)
-
The wheelhouse section has it's railings, temporally in place.
(http://modelboatmayhemimages.co.uk/images/2018/01/06/DSCF0885.jpg)
-
Hm, circles. Well, if you don't mind a little relief in your markings then you could go down the cut vinyl route and stick them on. I recall Dave Woolley masking his Russian carrier deck to spray the markings on, so if you can find a method on line then that is an option. I imagine it will take several hours to mask and about fifteen minutes to spray! Just make sure the base colour is fully cured before you lay masking tape on so that it doesn't peel off when removing the tape >:-o Also, I read recently that once masked and prepped, if you spray the base colour on first, it blocks any little wrinkles in the tape that cause uneven edges when you spray the marking colours.
There may be genric decals for putting circles and other shapes on, but I am not aware of any sources specifically.
She's looking good Ken :-))
-
What is the thinking with the flexible rail material .Would it not have been easier with brass rod.
David
-
Thanks for the comments Chaps.
I'm thinking of printing the circles as my painting isn't up to much. I'm going the epoxy route on the stanchions and the loose wire will be soldered firmly. (hopefully !)
Cheers
ken
-
I have made the circles for the flight deck by cutting them from half mm plastic card. I used a very sharp blade and a bit of patience and it came out well.
(http://modelboatmayhemimages.co.uk/images/2018/01/12/DSCF0892.jpg)
As the workshop was nice and warm I decided to try some winter 'spraying' . It's a good job I had the appropriate face mask as the smell was quite something.
The next little job %) was to add some red to the crane. This took a bit of masking up for the red bits.
(http://modelboatmayhemimages.co.uk/images/2018/01/12/DSCF0890.jpg)
Another colour added to the funnels.
(http://modelboatmayhemimages.co.uk/images/2018/01/12/DSCF0893.jpg)
Just the black tops to finish them off.
Work had to stop for the rest of the day and the door left open to warm the surrounding countryside. :} :}
-
As long as you are alright ken, that is the main thing.
-
The funnels are now painted along with the bow deck.
You will notice the lifeboat and stand have been finished but it still needs some little pulleys.
(http://modelboatmayhemimages.co.uk/images/2018/01/18/DSCF0894.jpg)
Moving on to the back end.
We have painted the fire hose support frame all ready for some water pipes to be fitted.
I have made some containers and just placed them in position.

Great Work Ken
You turn out some amazing scratch
built models in a shorter time than
it takes to build a kit :-))
Ned
-
Thanks Ned. I do like scratch building as it can't be compared to commercial stuff. :}
The wiring up of the crane is the next section. I had such a nightmare on the last one that I will have to re-design things a bit better this time.
Cheers
ken

Still thinking about the crane's motors. I have the miniature motors but what I need is two bobbins to act as winder drums. I've tried two disks glued to a small tube but this proved a tad flimsy.
As a break from this area, I have moved over to the safety net around the heli-pad. My wife came up with some 'starchy' netting which seems to do the job nicely. Here is all super-glued into place.
(http://modelboatmayhemimages.co.uk/images/2018/01/24/DSCF0905.jpg)
(http://modelboatmayhemimages.co.uk/images/2018/01/24/DSCF0906.jpg)
-
Onwards to the railings .......
I have decided I didn't like the multi strand wire and have changed it to 0.9mm single strand tinned copper. This has come out much neater and was easy to solder into the stanchions.
(http://modelboatmayhemimages.co.uk/images/2018/01/30/DSCF0907.jpg)
(http://modelboatmayhemimages.co.uk/images/2018/01/30/DSCF0908.jpg)
-
Finally onto the crane ....
I have fitted tiny capstan drums to the miniature motors and glued them to the crane. The control wires go up inside the crane and down through the shaft into the boat.
As a tester, I can connect 12 volts to the wires and the motors activate the Boom and the hook. You may have noticed that the drums are affixed on the ends, rather than central. %)
This does present a problem with lining up the threads but it's too late now to rectify !
My next task is to work out the swivel mechanism of the whole crane. %)

Hi Ken,
I saw your pulley quandry and thought of sewing machine bobbins. You can get them in craft shops and haberdashers assuming they are more or less the right size.
She's looking 'Seabexcellent' :}
-
That's a good thought and along the lines of what was done in end. I made my own bobbins on a drill fixed in the vice.
I couldn't use sewing thread bobbins you suggest because the centre hole was too large for the motor shaft. I ended up gluing them on. The bobbins are now off centre for the crane ropes which drives the thread to the sides. It's not a major problem as the side walls guide them into place.
I am working on the column drive system at present to rotate the crane.
ken
-
Ken you could have used a piece of dowel through the centre of one of these bobbins and then drilled to suit whatever spindle you had... These are what Ian was mentioning and are cheap as chips to buy. They come plastic as well
-
I appreciate this is academic now chaps, but I saw some plastic ones in Squires that needed assembly. I don't know why they were so but there they were!
