Hi there back again with the latest build, she is of a 25 Mtr tuna boat "Ocean-Dynasty" built at North Arm Slipway Port Adelaide South Australia 1980-81. This is my largest build so far at the 1:16 scale she comes in at 62" x 18.75 " or 19 & 1/8" O.A with sponson's depth 9", in her stand she has overall height of 4' 6".She has the same motor as the previous model an EMX 202 12 V aircon blower motor spinning slightly larger 120 MM propeller. I had the plans drawn up and the frames cut out prior to Dec 2019 , but first finished off the dungeon a new working area under the house first so no more sawdust over the cars and blowing up the stairway when entering the house from the garage, as they say Happy wife happy life ok2 . So started on her through January and finished about midd July. The back bone and frames are of Tassy oak ( frames are 30mm deep x 18 mm wide) ..cheers..
-
That’s a big boat O0 Looking forward to this one Brian and good to have you back on the forum too :-))
-
Amen :-)) its always a special occasion to see such craftsmen and women doing their art. I love the little touches such as using a strip of different wood for a certain job.
-
Hi guys, good to be back , I meant to start this post off a couple months back ? with the first photo looking into the new dug out L shaped dungeon (never big enough), starting to install her frames and as you can see she has a decent beak on her.This time I put small castor wheels under the base to make it easier to turn her around, and last photo running her chine stringer through... :-)) .cheers..
-
That dungeon/mancave looks amazing, what with the sink and good lighting and walls screaming to be covered with tools and cool gubbins :) I know what you mean about never having enough space Brian, you could have built a warehouse and still ended up filling it with stuff!
-
BB...
I went to the WEB page for the Ocean Dynasty build...... https://www.wcpfc.int/node/18901 (https://www.wcpfc.int/node/18901) and whilst certain data is provided, it didn't confirm form of construction
With the bluff hull frames & hull bottom we see with the model, was she a steel hull?
Derek
-
Hi Ballastanksian ,yes makes a difference ,and on cold chilly days like it is today just leave the roller door down :-) .
-
Hi Derekwarner, yes she was a steely ,and in that link you put up the photo of her there was later after she was lengthened for Purse seining...
-
Thanks BB.........
Are you cutting your own 30 x 18 mm section Tassie Oak frame material, or is it a Bunnings product?
As a flatish steel build, will you be deviating from your usual planked hull construction to marine ply sheeting for the flatness & just planking at the L shaped intersections?
Looking forward to Watching the build as usual :-))
Derek
-
Hi Derekwarner , ripping the frames and beams etc on the saw bench, yes not planking just ply and glassing the inside .....
-
Hi there , first photo ribbing on the deadwood area, with the transom I had a memory lapse when I cut it out and fitted ( I knew it had a curved transom ?) so had to re shape it so it made the model slightly longer ( if I don't tell any one they won't pick it up :-)) ), easy build this one with the sheeting the frames with ply will be glassing the inside, and showing the end result of having to bodge her tail (any way will be nice and strong) cheers ;) .
-
Super nice and tight work with that ply. Very satisfying.
-
Morning, fitted the nose cone in 2 pieces of 1.5 mm ply, the piece of ply at deck level is only there temporary , just to maintain the shape while fitting the flair around her shoulder etc.
Used Tassy oak for her heel and false keel running under her towards the bow area.Cutting out the ply for the entrance ways at the bulkhead to the accommodation area etc and fitted.....cheers :-) .
-
Morning, next section of photo's,are of bow section plated up ,then after taking the temporary section of ply from the bow area then laminated the inside of the bulwark's around the bow section, then ripping some more Tassy oak up for deck beams , and the arrival of her motor ....cheers.. :-)
-
Wow, was going to say only taranis can build this quick then I noticed comment in first post!! LoL
-
I really like the shape of these trawlers the bow looks so pointed its looks dangerous %% Its staring to take shape now Brian :-))
-
Hi Mark T, yes down south they like their fishing vessels with hooked noses or over exaggerated clipper bows ? O0 .
-
Hi, Some more photo's for the day , extra beams pre fitted as will make it easier to glass the inside of the hull before fixing them into position.I didn't use glass matting with the resin I used cut offs of heavy fly screen , I resined some of this a couple years ago and showed no signs of de laminating etc, gave her 2 coats of resin, before sanding then painting white undercoat then sprayed white gloss enamel...cheers :-)) .
-
Cracking work akin to that of member MissyD , a pleasure to watch :-)
-
Hi there, All the fly screen matting in with 2 coats of resin, the battery box for the 2 x 12 V batteries which will be wired in line , this will sit forward of the motor.Pre fitted side railings for the top deck area beside the wave breaker, pre fitting the motor base, and last 2 photo's after she was undercoated then sprayed with white enamel gloss...cheers :-))
-
When you mentioned ply I was suspicious for a second thinking that our Brian had been abducted and replaced by someone who didn't realise what the real Brian can do with traditional wood! Then I saw your surgical work with the ply and knew you were the real deal :-) I reckon I could get more putty under my thumb nail than you needed to fair the joins in the skin.
Super work Brian :-)) :-)) :-)) :-)) :-))
-
Hi Ballastanksian, very kind words ( where would you like the cheque sent to ok2 ) I know I used that and a bit more of Plasti Bond up the bow area to achieve the smooth look instead of the joined plating look.I finally got onto some 1:16 scale figurines .Showing the underside of the top deck aft section ( awning), easier to fit the beams etc before glueing it all down.Installing the wave breaker staunchon post...cheers :-)) ...
-
I always like watching your builds, it’s like watching a real boat being built! :-)) :-))
-
Thank you Dreadnaught :-) . Hi there, the pre fitted bulwarks extend down below deck level bit more strength , then braced into position prior to fitting the staunchon post ( a lot quicker than fitting all the post then planking, as they say horses for courses ? ) , after fitting each post ,then glue a dowel on the post edge which fits through the deck for extra strength.On the corners of the transom's bulwarks fitted tapered pieces to aquire the curve, same as was done below deck area on the transom's corners.The next 2 photo's show what can and does happen when you have a brain fade moment :embarrassed: ,had the model laying on it's side on the table just finished fitting thelast tappered corner sections turned and walked about 5 ft (was a bit windy that day) had gust of wind come in and she rolled off the table with an a;mighty bang when she bounced on the cement, was expecting the worst but luckily she only damaged the S.b side on her shoulder in front of the wave braker, had to fix the side rail bulwark and section of deck <:( . When I went up top for a coffee my Lovely wanted to know what the loud crash was , told her , her remark was how come I didn't hear you swear, said yeah surprised myself to O0 ...So once again have proven that as you get older you don't get smarter ok2 ...cheers.
-
Some more photo's of the build for the day, and the start of the w-house :-) cheers.
-
There is so much thoughtful carpentry going on here it’s just lovely :-)) Mind you if my build had been blown over I reckon I would have actually invented a few new words %% Great build Brian keep the pictures coming.
-
Thanks Mark T :-) ....Next section are construction of the w-house, the sloping section at the rear of the w-house will be the bottom section of the exhaust stacks .The biggest problem with building this model was not having enough photos of her as she was in her first few years of operation as they extended her stern area for purse seining , also changing her main deck and aft top deck area......cheers :-))
-
Morning, some more shots of the construction of the w-house...cheers :-)
-
Absolutely love to watch your work! Its been said before, it's like watching a full scale vessel taking shape.
Thanks for sharing all your builds!
Hama
-
Hi Hama I'm glad that you are enjoying the build .....With the next section of photos are of the exhaust stacks, as she has to be transported from A to B . So at this stage will make the mast (crows nest) detachable from the stacks and the stacks detachable from the w-house and the same with the w-house from top deck area, by the time the hull sits in the transport trolley it just squeaks in to the back of the Tucson .( that was the plan at the time of the build going by measurements, and surprisingly it worked :-)) ) cheers ...
-
Very nice work. You're building in a scale the original shipwright work can be followed and demonstrated for all to admire.
Rich
-
Morning, thank you Rich.With the next section of photo's , showing the bracing the 2 stacks together, I know it looks a bit rough with the section filled with blocks but needed something substantial for the base of the mast to fit to.An after thought to cut this section out below the w-house, glad i did as it gives an easier excess to the forward section..Along with the eyebrow staunchions put a filler section in for the joints of the first layer of 1 mm ply before laminating with another layer of the same thickness of ply......Cheers :-)) .
-
Very nice lines for a fishing boat. Is that a typical Aussie Tuna boat? That bow is very similar to the Indonesian/Thai trawlers.
-
Hi Steve, there was quite a few built in the late 70's early 80's with the extended clipper bows mainly for the Greeks ,Italians ,Croatians in the Tuna industry, as you can see in the few photos I have attached, cheers :-))
-
Hi there, next lot are,,,, as I mentioned before i have to make the top sections of the model to be able to come apart for transporting ,first 2 photo's are of the mast base, then making bits n pieces for the mast and crows nest ,,,cheers :-)) .
-
Lovely work Brian this build is immense :-)) When you say the stern was changed because of "purse seining" what does that mean? I've never heard of this before and are you going to make one of your realistic engine covers for this model too?
-
The crows nest is very shapely.
-
Hi Guys , as you can see in the photo's Mark T they extended the stern area to accommodate more deck area needed for the amount of net and skiff they have to carry, they did this with a few of the Tuna vessels down around Port Linclon area, as they went from pole vessels (poling tuna) to purse seining the tuna they have large tuna pens where they keep the tuna to feed and fatten them up before they are sold ,so some of the tuna vessels tend to be a working platform to carry pallets of feed out to the fish pens they have anchored in the Bays around Port Linclon...Cheers :-))
-
Hi there, few more shots of the build, another brain fade ( seem to be getting good at these O0 ) after making and fitting the pivot point for the boom then realized it had to pivot side ways as well.Decided to try another way of connecting the top lugs for the lifting boom, makes it stronger then just filled the cross slots in the end with timber.Decided to utilize the eye glass hinges been saving up in my container of brass scraps for the top lugs that will brace the mast in position...cheers :-)) .
-
Hi there, with these next few photo's are of the mast stays etc, then the deck machinery, with this model only had the 2 winch's on the front deck area,,cheers :-)) .
-
Hi there, these next photo's are of the net dinghy for the model, I found this was the easiest way to build it ???, good thing for the Dremel and File sander to cut and clean the inside of it out ( few more of it to come), cheers :-)) .
-
Lovely work Brian and it also gives perspective on just how big this build is. Some builders make boats the size of you dingy!!
-
Hi Mark T thanks for that, I must admit I like building the larger models but they start to get a bit heavy when you have to move them around or transporting them, the next builds are smaller one at 37 inches and 33.75 inches.I wasn't gong to go to to much detail with the dinghy, but where do you stop ?? same with the outboard it wasn't on the list but what the heck , the decals tracked those down on internet (early 1980's). cheers :-)) .
-
Excellent work. :-)) :-)) :-))
-
That little boat is a masterpiece in its own!!
Hama
-
Hi there ,thanks guys....Found a piece of rosewood to make the main deck ladder from, with the brass hand railing the top section looks a bit rough with the extra pieces soldered on this is to give it a bit more support for the timber capping she had all around the top of the railing.When I was painting one of the undercoats on with a brand new brush it decided to go on strike ( probably made in China O0 ) cheers :-)) .
-
Oops, I thought you were using the ferrule for a tool or for a certain metal shape you needed until it dawned on me that the paint on the bristles looked wet and it was odd not to see the piece being soldered.
Progress is excellent especially that gorgeous boat.
-
Hi there, some more photo's of the build, with the Crest couldn't get a clear enough photo of it to use, she had the main Crest one on her nose (under the bow capping rail) and the inserts of the main crest on each exhaust stacks, had a friend transfer them to inkjet water slide paper, then another undercoat applied to her bottom, cheers :-))
-
The brasswork around the search light looks very realistic I've not seen one done like that before. I'll keep that idea in my back pocket for the future.
-
Wow does not express my admiration enough. Your woodwork, brass work and laser work are truly splendid.
-
Hi there thanks guys :-) .Next up the rudder , from 1/8" brass plate, I made this one different to the last model's rudder, I have the rudder stock threaded so as to screw down through the top plate and also into the tubing ( on the rudder) then pinned (hasn't moved so far ).The next photo is a bracket at the back of the top w-house for the outboard to sit in .Now with these next photo's aren't to do with the build but has with some of my other model builds, I got onto 1 & half glass cabinet's from a second hand place, so took a few days off the build to work out how it went together , had a spare area in the garage to install it, it didn't come with any glass shelving so those pieces cost me nearly half of what the rest had cost me , would have liked to put 1 larger model in the centre of the display cabinet, but the cabinet needed to be a few inchs wider (which it wasn't) so at this stage they will have to satay scattered throughout the house and dungeon....cheers :-)) .
-
Morning :-) ...With the lettering under the shoulders on this model ,because they forward no fonts available so back to the drawing board , when finished I took photo's of the lettering's and the crest and sent them off to my friend as he was going to shrink them down for me to print off, he informed me I had the N's back the front on the port side (What ??? not happy Jan >>:-( ) so instead of re doing the whole name again I cheated and re did the N's and spliced them in O0 . Next photo's gave the outside hull her 1st coat of white gloss and the deck her 2nd and last coat.Bit slack this time with the motor no dummy engine cover ,but she did get a lick of paint and some transfers O0 .And sticking the windows in the top w-house...cheers :-)) ....
-
Just catching up with your build and its looking amazing; that rudder must weigh a fair bit and will help with the ballast. I have to say though - what a way to display your boats. They look great all together in the cabinet and what a collection too :-))
-
Hi Mark T, I think I need a few more cabinets though, trouble with building more or larger models would cost more in cabinets to house them ,as this one is number 29 :-) .With these next section of photo's selection of print outs on the ink jet water slide paper, and the hull given her 2nd coat of white gloss enamel.With the name tags for the stand I got caught ,I put it down to not waiting long enough ( like the following day ?) to apply the clear laquer coating , as within a couple of minutes of spray it actually changed some of the colouring under the water slide and also bubbled the gloss enamel (Not happy Jan <:( ) so had to sand them both back to timber and start again (luckily had spare print outs) so held my breath when spraying the second attempt :-)) .Nearly forgot about the top side bollards made those from my .357 mag shells ( left over from shark shooting days off the trawler,,oops sorry is that politically incorrect ok2 ) so brass and copper soldered.And painting the first coat of her Royal Blue trimmings, Cheers.. :-)) .
-
Hi there, well another beautiful day in paradise down here, well here we go, re designed the 120 mm prop for the model, also while I was in the mood I also worked on a 100 mm prop that I may install on another earlier model.All the bits n pieces all painted and ready to go. The previous model which was parked in the trolley sat it on the bench so as to modify the trolley for the slightly longer and wider model..Cheers :-)) ..
-
Good save with the transfers Brian; it just goes to show you have to have a bit of patience and a sense of humour when boat building O0 When I saw your propellers apart from the huge size of them they look like martial arts throwing stars :o Beautiful work as always :-))
-
I am intrigued - what is the intention behind the prop modification? It's very well done and looks real sexy, but why? Surely the reduction in area results in less drive, or is there some obscure effect taking place that makes that shape more efficient? I know some submarines had highly skewed props like that, but I thought that was more to do with cutting down the acoustic signature of the propeller. Do tell us why!
Greg
-
The props is how they make them Tuna chunks %%
-
Hi guy's ...They do look a bit like them Mark T , I dare say they would probably work with the same result if hit by one ( better keep them away from the Wife ) ok2 . Hi Sailor Greg,,,,Why ? Well its like when my Wife say's 'What did you do that for' ??? Because I can O0 ,I find that they seem to have a smoother cut through the water ,have quicker pick up from low to high revs, and in reverse with the less blade area no cavitation giving a quicker response pulling up in probably 1/3 the distance of the prop I replaced with one of these on a previous model.But that's only my own personal experience using them, yes Taranis I'd hate to put my fingers any where near them, I don't know about tuna chunks but I dare say there would be a few fish fingers spat out,,,cheers :-)) .
-
Hi there, next lot of shots of the build,,, Before and after spraying her final coat of her bottom in my spraying booth, the water slides on the w-house eyebrow and on the exhaust stacks.The rigging all finished, the mast and exhaust stacks will separate from the w-house, but I can leave it how it is for transporting, it wont fit in the back of the Tuscon (height) but sits on the front passenger seat.Working on the wiring for the RC side of it, and the name tags for the stand thankfully turned out with no more stuff ups .The motor attached to her base prior to fitting her into the hull...cheers :-)) .
-
Morning, in for my coffee break so good time to attach some more photo's.Laying her on her side doing few touch ups on the blue trimming, some shots of the Beech timber capping around the top decks railing, view of the hull all ready for the bits n pieces to be refitted to her, and last minute item I nearly forgot the fog horn which connects to the radar stand ,made these from 2 pieces of plastic bits i was given by another club member...cheers :-))
-
Hi there, some shots of her finished, the model comes in at 21.5 Kg or 47.3 lbs ( no batteries & ballast) cheers.. :-))
-
Beautiful :-)) I would love to see pictures of her on the water.
-
Wow another beautiful boat to add to your collection :-)) I would also like to see some pictures of it on the water as it will look amazing. So what's the next project Brian???
-
Looks great! :-)) :-)) :-))
-
Fantastic, again!! :-))
Hama
-
Morning guys,Thank you for all the comments ,just a couple of her here on the water (in this post) , the next post has her performing on the water.She has 2 x 12 V batteries (hull & batteries 23.5 Kg) on her first trial she had 16 Kg of ballast ,then on her next trials she had 20 Kg ,could put more in to push her down to her fully loaded capacity but no need to she runs nice through the water and stable while doing sharp turns (yes she is over powered but rather that than not enough grunt).Answer to your question Mark T , I have 2 on the go at present ,after making 4 at the same time a couple yrs ago said never again (so only half lied O0 ), they are on the smaller side compared to this last one , another 2 trawlers from our home port of Brunswick heads one at 37.5 inch's the other at 33.75 inch's both chine hulls,,,cheers :-)) .
-
That's really good looking boat. Might just about be my favourite so far.
Well done, better start planning a bigger cabinet.
-
Hi there, Hi Steve yes very happy with her turn out , actually need quite a few more cabinets O0 .
-
Hit the wrong key :embarrassed: ,well here is the last section of photo's of her (if I knew how to put up vidoe's up would do ?).We had picture perfect morning for her launching, they always shrink when you get them on the water till you have to drag them out and load back into the car, catch you later Cheers :-)) .
-
Beautiful. :-)) :-)) :-))
