Hi Jimmy,





You will have to move the track on the scenic section to the bottom of the board in order to line up with the bottom line on the sector plate. This will allow you to use all the tracks on the sector plate. If you leave it as you have it now you can't line up the bottom line of the sector plate to the 'in-road'. I learnt this from experience :roll:

PS A sliding sector plate is called a 'traverser' if you need to Google some more,

Ok so after working a set of night shifts where all i could think about was my layout and how to do the fiddle yard / sector plate / traverser....

after taking advice from the internet / magazines / Gary & Doug (dooferdog) i decided to go for a sector plate.

i spent most of the afternoon today after not a lot of sleep playing with cardboard cutouts. i have decided that with a sector plate i can shorten the fiddle yard increasing the scenic area.

i can just about fit in a end pivot sector plate so after spending hours with cardboard, string and pencils i decided what the hell, and this is what happened....... no going back now.........





if this does not work then i may hold Gary and Doug (dooferdog) responsible  :doublethumb

I'm sure it will and I'm sure once it's done, I will look at it and say "thats a bloody good idea"

I'm just doing some catching up Jimmy and I've got to here .......................

Love the Airfix jeep - great looking model, as is the rotten carriage.  As Mick said, 2 tanks on a bolster is 1 tank too many ............:roll::roll:  They're heavy beasties. ;-)

I'm glad you opted for the sector plate rather than a traverser.  Traversers can be a PITA to get them to work without any binding.  Sector plates are a piece of cake in comparison.

Looking at your baseboard, unless you add another cross beam, you don't have any option other than an end pivot.  To my mind, the only advantage of a centre pivot would be if you wanted to swing the thing through 180 deg. so it could be a "Ro-Ro" (roll on- roll off) configuration.

I was considering keeping the tanks as they were but I have decided that I would never be happy with them so I have a couple of well wagons to convert so will put one tank on each which I'm sure will look much better, (however it will be a lot of work)

With regards to the sector plate, I still have a lot of bracing to put on I have a bit to go across the front and another to go at the back. I don't ever want to swing the sector plate 180 which is why I decided on end pivot.

My next purchase will be some copper clad PCB so I can play with some track.

Good luck on it. Track making can be a bit fiddly.

I'm not that brave yet, although I do fancy building my own track.

What I require is pcb board to solder the track to at the joints of the sector plate.

i have also made a start at changing one of my boogie bolsters, the one with two tanks on it, i have come to the conclusion that in real life it would be well over weight and if i plan to exhibit the layout (my aim) its gotta be right!!

so purchased was two old bachmann LMS well wagons, load taken off and put into the box of spares for later if required.
the wheels are plastic and very crude so these will require changing.

also with the load gone i found them to be very light so using weights designed for wheels i have added some weight.

i will build a false floor and place one tank of each........ watch this space..........

Hi Jim

I love your modelling skills. The torpedo boat is a gem, as are the weathered bolsters, guns and the jeep. I feel a bit of a rivet counter, but if you are going to go for one tank on the bloster wagon, I would opt for either a Sherman, Churchill or a Cromwell from the Airfix range. These would fit the D-Day period of mid 1944. The Matilda Mark II was obsolete by 1943 and taken out of front line service. Whilst it was a tough little tank, it was too slow and the turret could only cope with a 2pdr gun. By this time most tanks in operational service had at least 75mm guns. Otherwise a great project, with some stunning modelling.

Bob

Thank you for the kind comments, I am learning as I go along with this build and it's quite a bit of trial and error.

I can't put a Churchill on the well wagon as its to wide so I will have a load of churchills sitting in the docks. I think I will have to stick with a little bit of modellers license when it comes to the use of the Matilda's

I have built something new which I will post on this thread tomorrow

so when i first came up with the idea of this layout i knew that with regards to the rolling stock i had to have some variety o keep interest as i do intend to exhibit the layout (if it is ever that good.) this also stretched to the LOCO's i decided that these needed to be something a little different and special. i think i need aout four or five LOCO's and that they need to run very well and very slow. and of course be DCC.

so off to the wonderful of the internet, i quickly discovered that during the war needs must which resulting in all manor of road vehicles being used for use on the rails in the most crude ways.

unfortunately the willy jeep is just small but looks amazing on rails.

i stumbled across the American GMC 6x6 truck. i found that these where used widely and more of interest to me for shunting and that they where very capable shunters being able to shunt four or five small wagons or one or two large wagons. (perfect the seed was sown.)

a bit more research and i found that most where constructed on old wagon chassis or reinforced girders  with a lot of ballast added to the rear to aid traction. as there seemed to be no rule and no two looked the same this meant that i can build something that looks good and works instead of a perfect replica. 

  hopefullyyou will agree what i have built looks as if it was was there working hard in the docks.

so i started off buying a old airfix GMC truck kit. i then found a couple of old ratio truck kits that i had built a long time ago.

i stripped the wagons to the chassis and merged two into one.

but what to use for traction, well this comes from a simple motor bogie which was converted for DCC use.





i quickly found that running as is the front wheels derailed on all bends and points. at this point i almost scrapped the project. but then decided to add a centre mounting point to the motor bogie seen in the picture which allowed the motor bogie to pivot in the chassis without it being visible,

next test run and perfect. i was happy again.

however quickly discovered that if i wanted to run at slow speeds or even shunt then this needed to have some weight. now it is finished if it was a boxer it would be in the heavy weight class. (she is very heavy).



in the back you can see the DCC decoder and some of the weight. more lead was added to the chassis so that the entire chassis from front to back is also lined with lead.







i only added a coupling to the front as that is the only end i will couple up to. the front wheel set is still the set i used for mock up i current have a 10.5mm disc wheel on back order which will look much better.

so what do you think??

the below video is final testing under load on my dads layout.

That does look good and it will be an excellent talking point during an exhibition. Thumbs up from me ! :thumbs

Cheers, Gary.

That's an excellent project Jimmy - imaginitive and a great talking point. :cheers

As it's such a good idea, a couple of suggestions if I may ...............:hmm

1.  Get rid of those dreadful TL couplings.  To me, they're the pits on exhibition layouts.  Either go for Kadees to allow for complete "hands free" operation or miniature 3 link couplings.

2.  Have a play with the CV's on the decoder.  I'm not sure if you intended to show any slow running or just the power of the beast, but with DCC, you should be able to go and cook a meal whilst it covers 6 inches of track.  To me, that was way too fast.

Just my observations but, given that the models themselves are so good, it would seem a pity to detract from them by less than perfect operations. :thumbs

I'm still learning when it comes to dcc and decoders I have had a little play with the cv's I have shushed the starting voltage the mid and the max just need to get play with the throttle curve. It will run so slow I will do another video on a bit of clean track to show you.

I am considering different couplings. The one on the front I don't like and was a sort of temp measure to see if it would pull the wagons.

I will look into different couplings but I'm still learning, it's like the sector plate I'm not sure what im doing but will give it a go.

Hi Jimmy,

That GMC truck looks amazing, great modelling.

Hi Peter,

looks to be only the ones at the beginning of the thread are missing. One pic of a prototype is showing on page 1 for me even when I log out and view as a guest. The pictures seem to start to show by page 5 (some on bottom of page 4 as well)

So they do Simon - I didn't go far enough ............:oops:

On a technical point - I note the Fordson Major has the rail drive connected to one half shaft only.  I don't think that would actually work on that particular tractor.  They were not fitted with a differential lock and therefore, putting a load on one half shaft (which would equate with locking up one wheel), would make the other shaft spin at twice the speed leaving the loaded shaft stationary.  I looked carefully but couldn't see any evidence of a means of locking up the free shaft.  Try it in your car.  Get one wheel stuck in mud and the other spins at double the speed via the diff. gearing.  That's how they work otherwise you wouldn't be able to turn corners without wrecking the drive train. ;-)
