Plotting the reverse curves..

As stated in the previous post, the planning for the extension of Victoria Street is now a work in progress. The issue is that I have some domestic obligations to abide by in regards to the extension, that is that the study/man cave has a boundary line, that I dare do not cross, as not to invoke the full force of the domestic authorities.

The reverse curves that I have planned for the extension are an example of the town planning that occurs when former Melbourne municipalities employed either different and/or incompetent surveyors to plot aligning streets/roads from one subdivision to another.

There are still to this day plenty of reverse curves of the Melbourne tramway system that obviously traverse within the boundaries of the former municipal authorities, these roads and the real estate were plotted and sub divided when small suburban councils were operated like personal fiefdoms. The tramways came along later, and had to fit the alignment.

Classic examples of these are the route 1 to East Coburg, that cranks from right to left from Lygon St  across and along a short section of Albion St into Holmes St, in East Brunswick.

Another less extreme example is the route 12 to St Kilda/Fitzroy & Park Streets, this deviates from Danks St across Mc Gregor St, to Patterson St, in Middle Park ( the eastern edge of the former City of South Melbourne).

My example, as plotted, forecast and basically dreamt up, is so far according to clearance testing seems to be a working proposition.

The two ends of the layout were plotted, (the railway station and the fiddle yard/new ammo factory) across the available space left in the study and the potential bench/layout area.

 

The faint pencil lines show the extent of the chicane

module, the ammo factory module to the lower left, the

railway station module to the top right, the three way point

leads into the (future) depot. A Peco set track point has been

plotted to feed the depot three way point.(all going well?)

 

The Ammo Factory/fiddle yard module will have another

commercial Y point fitted for the siding. I have done away
with building a single blade point for reliability.

 

 



 

The pencil lines show the overhang of the running boards,

as these are my longest/widest bogie trams, all others do fit inside the envelope.

 

 

There is enough room for everyone.

 

 

Enjoying taking things further than pencil and paper from under the wires,

Plotting the course.....for the new year.

Almost two years ago, I posted a punch list of things that I wanted to be done with the layout.

**Sunday, 3 February 2013

Time to get organised.

Several projects have been horribly neglected since becoming besotted with DCC, materials for other projects have stockpiled to the point that the domestic authorities are in the process of intervention.

PROJECTS THAT REQUIRE ATTENTION!!!

•  The illumination of Victoria Street, so far only one module has been completed, The Railway Station. The rest of the layout still resides in the dark ages.

• Project completed for Caulfield Exhibition.

 

• The animation of the crossing gates.

 

• Nailed it!

• The construction of several other classes of Melbourne trams, these will include the W2, X2, VR, PCC 1041 and a Z1/3, plus the reworking/painting of several existing models with the correct decals and the installation of DCC friendly lighting.

• Needs to improve, I have been distracted by other non Melbourne models, but this W2 from the dark arts of 3D printing looks very interesting. This year this will be the year.

• The construction of 2 to 3 more modules featuring back scenes such as residential, educational, and industrial to compliment the current retail, recreational and railway aspects, all with simple trackage to offer longer operational running.

• Planning in progress, intend to do clearance testing of chicane with flexitrack before committing to building module and depot. Watch this space.

• The updating of the track wiring for DCC, and the elimination of terminal strips in favour of plugs and sockets.

• Project completed for Caulfield Exhibition, with the ability to run DC

So there is the rundown of what I promised myself, and the results. The Blog not only chronicles the progress of the layout, but is also a reference to projects planned, attempted and executed. This also includes the spontaneous refit of the study that I did last year.

Some housekeeping has also been done, W5 800 which blew a motor at Caulfield has had a heart transplant and is now back in service.

The Bride's parents bought me some weathering pastels (Pan Pastels) for Christmas, I have few Bachmann Brill bodies to practice on before I grubby up my fleet, plus that I have been reliably informed that 'less is more' with this medium unless I want my models to resemble drag queens.

What will the new year will bring...

• Hopefully an extension to the layout.
• Some different Melbourne models to be built and modified.
• More DCC fit outs.
• Experiments with live overhead on DCC.

From under the wires with a new punch list.

Well, That was quick.

It is that time of the year again, another year done and dusted, The layout underwent a fair bit of work, rewiring for DCC, building and street lighting, the Caulfield Exhibition, then the installation of the animated gates. Fun times all round.

So as per usual, and somewhat late this year, the time honoured Victoria Street Christmas Card.

 

 

The season brings its annual wishes and hazards, above all be safe, enjoy/endure your family, reflect on the year, and try not to eat or drink too much.

 

 

From under the wires, and the LED Christmas lights that I will harvest later...

'Open Sesame'.........'creak, groan, clank'

Yes, I have done it! I have finally animated the crossing gates of Victoria Street. Another item has been ticked off the bucket list.

 

The finished product.

 

 

The gates are operated by a Tam Valley DCC servo decoder, the crossing lights are controlled by a six function decoder. The four crossing lights are LEDs mounted on the shafts of plastic provided by cotton buds, each LED has its own light feature, two are alternating strobe, one the Mars light function and the other the rotating beacon. This provides the prototypical mismatched sequence of rotating beacons that were installed at these crossings.

 

 Also the tram signals are operational, with a fibre optic thread running from LEDs using the other two functions (headlights). A LED is mounted on the facia in parallel of the tram signal to show its status.

 

An OFF/ON switch is fitted between the DCC bus and the servo decoder, plus the six function decoder in so to isolate the set up when running 'antique' DC rollingstock. 

 

 

 

Another dodgy video, but it works.

More on the Gates

Now the fun part of installing the mechanism/control for the gates to the module. Holes were drilled at the base of the pivot points of the base board when the module was built, in the hope at the time.

The servos are fitted on Brunel Hobby servo mounts in a way not envisaged by the designer, the servo is mounted upside and with the inner side of the mount missing to allow the sweep action of the servo crank. The pivot pin is made from copper wire soldered to a copper wire 'staple' that that is hot glued to the crank, the pins of the 'staple' lines up with the holes of the crank, and the pivot wire lines up with the centreline of the servo shaft. A clearance hole was drilled in each of the servo mounts for the pivot wire to protrude through.

 

One of the four servo assemblies.

 

 

The crossing gates are readily available, made by Peco, while British in origin, they have been kitbashed and details added to make them more like the older style gates that dotted the railway network prior to the more contemporary boom gates. These were drilled out with a pin vice with a 1mm drill bit, along the centre line of the hinge pin.

(The copper wire will 'give' in the event of impact,

the post is pressed fitted onto its base)

 

Before with the crossing lights.

 

 



Work in progress

(the servos are pinned with thumbtacks until final positioning)

 

 

The front of the module will be replaced with a perpex window so to keep an eye of the inner workings.

"Open up the gates!"

One of my many projects on this layout was to somehow animate the gates of the crossing square of Victoria Street, I do now believe that I am a step closer to fulfilment.

I have glanced over the possibility of using servo motors in the past, but had no real idea how to make it all happen, today I stumbled across the dark arts of Tam Valley Depot being offered by Brunel Hobbies at the Croydon Model Railway exhibition.

After parting with/investing some cash, I came home with a servo decoder and four servos, in the process of cooking the Sunday roast, I nutted out the how to put it together, then program this collection of components, and made it work as a proof of concept.

Some happy snaps...

 

 Blu Tak is a wonderful product.

 

 

The entertaining part will be fitting it under the module

and making it work.

 

Behold the wonder of technology.............(and dodgy video)

 

 

some tweaking will be required, but that's where the fun is.

My cup runneth over again..

 As per usual at this time of year I have engineered a week off to co-inside with the Melbourne Cup Carnival, and as per usual there is a punch list of stuff to do around the house that not only would choke a brown dog, but also a thoroughbred.

 While I am permitted to wander down to Flemington (with the bride) to catch up with mates, sample a few beverages, and give money to bookies, the off days include a burden of tasks to be completed to the satisfaction of the minister of war and finance.

 So here is my homage to the spring race season, traffic mayhem, punters everywhere,  unpredictable weather and trams.

 

 

 

Planning is in progress for the extension....
