Hello !
I am going to start the building of the "Sentinel" from Model Slipway and I have a question about the stabilisers. In the instruction booklet, there is nothing that explain how stabilisers are set from the hull to the brass plate top bearing. The both tubes and bearing tubes for the stabilisers are not provided in the fittings bag. I think they were designed to be fixed at the begining because there are 2 emergences on the stabilisers.
For those who built this model, are there some pictures about the setting fo these stabilisers. I saw this photo on the forum and I would like to get more details.

Thank you for yours answers

Not an expert by any means but im sure i have seen this exact same question on rc groups.com
Some chap got them to work with the rudder which made an excellent model indeed. Hope this helps.

I hope not its one of mine.
See if these help. Remember to keep top of shafts of stabilizers as far above water level as possible.

Hello !
I think you did not understand my question ... No problem for me about the mechanism with rudders and trims That only concern the installation of the stabilisers
as below:
(http://img707.imageshack.us/img707/7337/p1040544b.jpg) (http://imageshack.us/photo/my-images/707/p1040544b.jpg/)
The part showed in black goes into the hull but the one in red must be cut otherwise the stabiliser should not be free ... Right or not ?????
(http://img809.imageshack.us/img809/5859/dscf0039iv.jpg) (http://imageshack.us/photo/my-images/809/dscf0039iv.jpg/)
If someone can explain how to instal what I show in white on the picture : the installation of tube and bearing tube to the stabiliser : glue or welding ??
Thank you
Chris

I built the Sentinel and did not connect up the stabilisers - just fixed them to the hull. She still turns on a sixpence without them working. Unless you desperately want to have them working, I wouldn't bother.
I heard a story from one boater who saw a model Sentinel with stabilisers turn too sharply and tip over, as they actually de-stabilised the ship.
-
Hello Spook !
I think I will follow your advice .... I am going to fix them to the hull.
Bye !

Rubbish!! I run mine using an ACTion P94 which will allow the boat to turn in its own length and it has come nowhere near tipping over.(http://i124.photobucket.com/albums/p8/DickyD_photos/taz.gif)

I agree, Richard. The stabilisers on my Sentinel also work and it's never even come close to tipping over, no matter how hard I turn. If a Sentinel did capsize it would most likely be due to the fact that the superstructure was built too heavy, or the batteries were not right at the bottom of the hull. The other possibility is that the stabilisers were connected wrongly, they should turn in the opposite direction to the rudders, forcing the hull upwards in a turn.
Peter.
-
Rubbish? No, Like I said, mine turns on a sixpence with no stabilisers - you just don't need them on the model, unless you're a perfectionist.
-
Spook, I'm no perfectionist but I decided to make the stabilisers work on my Sentinel simply because I could :-) I don't doubt that the boat performs well without them; the "rubbish" refers to the story that working stabilisers caused a model to capsize. As I said in my previous post, incorrect set up could be a problem.

Hello !
I saw I made a discussion concerning stabilisers working or not working !!!
But thanks to a member of the forum riggers24, I found a response to my question how to set the stabilisers system to connect them to the rudders later.
The manufacturers display model has the rudders connected to the stabilizers using the kit white metal rudder arms. (The kit now includes a diagram showing this option). Not knowing of this, I did my own thing. The two pins on the stabilizers were removed and drilled at the largest pin position to accept 4mm diameter brass rod. For accuracy I used a bench drill on a slow speed; too fast and the metal would have melted. I made two tubes similar to the prop tubes but only 15mm long with a 4mm clearance hole, and glassed them into position. The stabilizer shafts were pushed through the tubes and two commercial plastic rudder arms clamped on the inside. I discarded the kit white metal rudder arms and made new triangular ones with brass plate soft soldered to brass collets.

-
Looking good already. :-))
Make sure you have some sort of protection between the wood of the stand and the hull, to prevent damage. I can't see clearly in the pic whether or not there is any there. I use either strips cut from a mouse mat, stuck on with the rubber side up, or self-adhesive draught excluder strip, with the ends stuck down with tape.
-
Hello !
Friends of mine on a french forum are not agree about position of the stabs on the hull. They should be in horizontal position.
What is the real fonction of those stabs ..... To stabilize the boat or to turn shortly ?
In that case, can we name them "stabilisers" ?
I would like to get some pictures of real "Sentinel" on a graving dock.
Thank's
-
Send a PM to Dave [ACTion] he used to work for HMCC and designed the kit for Model Slipway.

I have many of Vosper's own photos showing all aspects of "Nellie" (including the stabilisers) but I'm afraid we are not allowed to publish them here or anywhere else due to copyright. Hiowever if you send me a PM I may be able to help ok2
BTW my original plank-on-frame Sentinel does not have working stabs and yet it turns without any noticeable leaning over. It also has 6mm less draft than the kit version.

hi
If this model of the Sentinel is built the same way as Dicky D's was built, I can vouch that it is an extremely stable model - I had the privilige of actually launching Richard's model for its very first Baptism in the lake :-)) I had heard that these models were slightly top heavy and therefore unstable so I did what I class as a 'safety roll check' before I released it for Dicky to sail. I turned the model on its side so that the side was under water and released it to see if it would right itself. I tipped it well passed the half way mark and it still righted itself - the reason for this is that the lake Dicky sails on - you can lose a model in the middle and would have to hire the Russian Mehr submersible to retrieve it :-)) we didnt want him to lose his model through a gust of wind - mind you I had to duck out of the road when Dicky shouted.... <*< <*< thank goodness it sailed fine!!!!
Little bit watta on the inside though, where I tipped it too much. Happy Days Dicky - hope we can get back down there and have a good day at the pond :-)) :-))

No, I fit the model with L/H and R/H Brass C-Type propeller ... By writting the type of the propeller, I forgot to add R/H.

Hello !!
The superstructure of the wheelhouse roof :
-
Hello!
I have a question to those that built the "Sentinel. It's about the wheelhouse roof and after cutting pieces 119 and 120.
FIG 13 on the book is not very clear!!!
Look at the pictures
Which piece to adjust (see red arrows) ......... I think of 120 to cut
Thank you for your answers
-
119 should sit squarely on top of 112 and 113. 120 should be chamfered along its rear edge to but against 119. The front edge should sit on 118 which should be chamfered to accept it. Finally the front edge of 120 should be chamfered to match the slope of 118.
Pieces 121 and 122 are then fettled to fit.

Good evening !
Here is the pole mast with different antennas.

Bloomin heck Chris, that is a master class in soldering right there! Impressive control of thy soldering iron.
-
Hello !
Merci Sir Gazou !
To Ballastanksian : no soldering only Z-POXY Resin and Hardener 5 minute formula !!!
Very good and strong for metal ......
-
Christian you take a big risk by trusting the glue 5 mn, it is not solid.
It is going to break in the first small shock
You have to weld these parts in the silver.
I like very much the SENTINEL, it is an attractive boat
-
Hello !
Work goes on ........
Setting and soldering yard arms and making of the towing stern light mast.
Question : are there "Sentinel" with another colour than grey ? I think about the white colour of the US Border Coast ships ...
-
When HMC&E was eaten by the Inland Revenue, the former preventive work went to the Border Agency (or whatever they were called that week). At that stage 'Nellie' was given a set of fetching red, white and blue stripes down each side and a subtle logo (!!). Apart from that there was no colour change - there being only one boat of that type in service with the UK. The US Coastguard operates dozens of similar V-T Island Class vessels with their white colour scheme, but that variant doesn't have the "blockhouse" Ops Room immediately behind the wheelhouse/bridge. It also has a more complicated lattice mast.

It may be time for an upgrade on mine, those stripes look quite good O0

I agree with you Peter ........ My "Sentinel" will be like that one !!!!!!!!!

Hi !
Here is the rigid inflatable boat
-
Interesting combination of etched and plastic sheet for the doors, it works quite well.
She's coming along fine, are you happy with the progress?
-
Hello Ballastanksian !
It takes time and I enjoy it. It's not a model for a beginner !
I try to add some details compare with the real boat
-
Good evening !
Some news about the davit
-
Not sure about new colours ,george
-
The word Challenge springs to mind seeing that interesting structure Chris!
Lovely piece of work.
-
Hello!
I ask a question for those who realized the Sentinel :
I would like to see a photo of the hatch equipped with the davit .... I mean the hatch full featured removed from the aft deck
Is it easy to remove it with the aft deck handrails and the davit ?
If somebody could show me a picture just of the hatch to have an idea.
Thank you
-
These pics any good? Best I can do at short notice.
-
Chris67,
Any good
C-3PO
-
Thank you C-3PO and dougal99
Beautifull works !!!
But can you lift off the hatch from the aft deck as shown at the notice book Fig 4 and Fig 7 (Deck, Bulwarks and Hatch)
From yours photos, I imagine all the rear deck is fixed !
-
Yes the rear hatch lifts off. I use the vent to pick it up, I haven't got a good picture and the model is not readily available to photograph unfortunately. This photo is not very good but shows the rear hatch removed (at the top of the photo).
-
Thank you dougal99
I can get an idea of the layout of elements on the rear deck.
-
Hello !
New pictures ....
Fitting with waterjet and a new platform diving (stronger)
Painting of the various parts before their installation.
-
What do you think about colour in spray "green Nato" from TAMIYA for the deck compared to "Mat green 78" Humbrol proposed by Model Slipway ?
Humbrol leaves tracks of brush .......
If you have another kind of green to propose ?
Thank's
-
Concerning colours for the green, I made photos with the 2 shades of green
Photo one : green Nato (Tamiya) on the flying deck
Photo two : a sample green with green Nato (on the right) compared to Mat green 78 Humbrol
You will notice the green Nato on photo 1 has the same shade as mat green on photo 2 : problem of luminosity in the room
Photo 3 : I put the sample on the flying deck to have an idea !
-
The Nato one is much richer and would probably weather down to the Humbrol86over time, but I do like the Nato green.
-
I used the Humbrol green on my model, my reason being that Model Slipway would have done their research and recommended the appropriate colour.
Peter.

The real deal c/o Vospers.
BTW If 3CPO's RIB pictures aren't of my original plank-on-frame Nellie then someone has done an incredible job of copying it. I sanded those RIB side stringers from 0.8mm ply one Boxing Day morning, with the most tremendous hangover......

Vestdavit in Norway supplied the ones for the Armidales which are similar.
They have details on their web site of various types.
-
Very nice build Chris, :-))
John
-
Thanks Brian,
Thought they looked familiar.
I work at Austal Ships and was on the Armidale Project from the start, also the Cape Class, which use Vestdavit equipment as well, a very good product. Talking to the Reps who come over to commission their gear, the Davits on the Armidales are their most used system in terms of number of launches/recoveries per week/month/year. Bearing in mind that they also supply equipment to many Navies, including the USN for the Nimitz Class Carriers!
The Armidale davits are rated to 4.5t, and the Capes 6.5t.
Nige
-
I can confirm that it is a VEST davit with a 6.5M RIB. I wonder if they managed to sell her and how much they got? Liz told me it was just a bit too big for Sawley Marina......
