Oil Pier - First attempt at airbrushing

Well, it definitely seems like the old days again! Fortunately I have more time for making models, and also upgraded my arsenal with some very important tools that were long overdue - a Dremel rotary tool and an airbrush are the top two recent acquisitions.

So when I started working on the oil pier, the focus was more on using the tolls as well as building the model! Hence there is not going to be a step by step construction post for this one because we simply didn't have the patience to take photos after every step - we were two excited to build it and then take it straight to the paint booth... I mean the cardboard carton that acted as the paint booth!

First, here is the in progress photo of the facilities of the oil pier. Given how small this pier is - there is basically nothing much in terms of operations. Small ships/barges unload oil that is stored in the 4 relatively small oil storage tanks. Then the the tanker cars are loaded and the oil is shipped to the local businesses. The oil storage tanks and the ships were built long ago, so I started with the tanker car loading platform and the small pump-house-cum-control room.

The material of choice however has changed considerably - except the base which is cardboard, everything else is either styrene or plastic. As per my trademark 'scrap-building', I have used some leftover parts from the ME trestle kit, as well as the sprue of the same kit used to make the piping.

My initial thought was to simply model a couple of hose pipes connected to the ship to simulate unloading, much like below.

However, when I started finding some prototype photos, I found that this is not really how the oil unloading happens - not even in the smallest of the ports. What they use is something like this, called the loading arms.

So I found a few drawings online, and decided on this one - simple enough for my tiny oil pier, but keeps is real and prototypical.

The material I used for the piping is also something very new to me - aluminium tubes. Though I have used them before, I have just cut them in straight sections. Given I did not have the L pipe joints in N scale, I had to use my new Dremel rotary tool to cut, bend and shape the pipes - sorry, no progress photos from here onward since we were building and discovering quite a few things at the same time, we didn't really think of taking progress shots.

So here is the final result - all weathered to match the tone of the rest of the layout - the only thing pending now is completing the mooring on the ship, and then this section of the layout is done.

Motorized Lighthouse

First project in the new apartment, again something that is long pending.

Though I made the lighthouse nearly 5 years back (Gosh! time flies!), I never got around to motorize it. While re-assembling the layout in the new apartment, I decided to start with this one since I already have all the materials needed to motorize the already built structure - it's just about attaching the lens housing (which was also made nearly 4 years back) to a slow motion motor.

The first step was to measure the space and clearance for the motor:

Then I'd cut a Masonite circular disk matching the inner diameter of the base of the lighthouse

The central hole was made to fit the motor bolt thread of the motor housing

The motor was then fixed to the board,

And then test fitted at the bottom of the lighthouse to check for clearance etc.

If you see the original construction details of the lighthouse (and many pictures thereafter), you would notice that the beacon housing already had a light installed. I just tested it's position and made sure everything is in it's place

Next step was to attach a shaft to the motor. Now this is where I again switched to 'scrap-building' mode. I didn't have a hollow shaft of suitable diameter with me - neither styrene, nor metal. So I went scrap hunting that can be made into a suitable hollow shaft, and I found a non-working pen. This was a gift from Brooklyn Locomotive Works, so I thought what could be a better place to utilize this than on an N scale Layout!

All the internal mechanism of the pen was removed - the tip side of the pen meshed nicely with the motor shaft, so I just secured it by drilling a through hole on the pen and securing it to the motor shaft using a pin (which was actually a part of a paper clip):

If you follow my work closely you would notice that one of my major focuses is always easier maintenance, because in my experience, things can go wrong at any time. So I decided not to permanently attach the lens housing to the shaft. So I created a removable section that tightly fits to the upper portion of the pen, but can be removed if required.

Now, if you are wondering how I found that lens - it is actually a contact lens packet! Some of the contact lens packaging have a perfect lens for model making - perfectly shaped, made of tough plastic and has very short focal length which is perfect for a lighthouse animation.

Here is the final shaft assembly with the lens:

And here is how the assembly looks when you 'cover' the shaft with the lighthouse structure. The light bulb hangs from the ceiling of the beacon housing and sit along the axis of the rotating, hollow lens housing.

And here is the lighthouse totally assembled:

Final test before installing on the layout

And that's how it looks when installed:

Here is a very short video to show it in action - Technically this is a 'fixed and flash' lighthouse with no eclipse:

All the photos and videos are with my phone, hoping to get a better composed video soon - may be after I finish some more work on the layout. :)

5th home for Wrightsville Port

When I'd set out to build this Model Railroad back in 2010, very little I knew about the road ahead of me. Well, you might say that you never really know the road ahead, but you have a general idea most of the time, you tend to follow a 'track' (Pun intended!) - you know where you are going, you know the 'stations' to come and you know the timetable. For me, it has always been more of a free flowing road trip for last 5 years - I worked in 4 different companies, all in very demanding jobs, moved to 5 different apartments and 3 different cities. Now, I had no idea back in 2010 that stability will be so hard to get - especially when we bought our own apartment back in Calcutta, but life had different things in store for me than what I'd thought, and things changed. Just to make it clear, it changed for better.

That's where I see the biggest success of Wrightsville Port - It stayed with me for last 6 years and never been a headache during all these movements! It was built as a portable layout, yes, but I never thought that it would travel to so many places (and I can assure you, it's not done yet!). Every new move also presents me with the opportunity of fixing and improving a few things. The layout is generally made clear of all buildings, ships and most of the details - they are removed, packed and shipped separately; only the permanently glued details and the main lights remain on the layout. This gives me the opportunity to work on the wiring when the layout is taken down (it takes 2 people to take down the baseboard - so far it has always been Mouli and I), so we did it this time too. However, this time I also took the opportunity to build a brand new acrylic dust cover for the layout. A dust cover was long over due, and 6 years of dust already made some damage despite my best efforts to clean the layout. I bought a sheet of 2mm clear acrylic, cut them in strips of 18" width and used a heat gun to shape according to the unique contour of the layout. The top is made of PVC foam in two halves. All in all, it takes about 60-90 seconds to remove them, and about 30 seconds more to assemble  - pretty acceptable before and after an operating session.

So, here is Wrightsville Port, happily settled in it's 5th home! This time even the dimension of the room is just made for the layout - 9' X 8' - gives snug fit to the layout and the staging-cum-bookshelf, with enough room for me to stand and operate.

This experience of working with acrylic sheets and PVC foam board is going to be important though, because I think I found my ideal material for modern benchwork that is far easy to work with and has many benefits over plywood - so the next project is definitely going to have these two as the base construction material - however, more on that later.

Some more detailing of the port

Well, despite having very less time for modeling, it seems I have renewed energy to see this project through somehow. Though nothing major, I added some more odd details around the layout, one of the major ones being installing over 20 bitts around the quay. Previously, I used various methods to make bitts, but this time I took to an easier path that can make really strong bitts - strong enough to take mooring line of size 8 threads anyway!

Couple of important aspect of my method is that firstly, my port surfaces are all cardboard. Secondly, underneath that cardboard throughout the edge of the port it's foam.

What I did first was painted a bunch of wooden toothpick burnt sienna. Notice those curving on top of the toothpicks and the big crevice right below the top 'blob' - that makes them natural selection for bitts.

I then drilled pair of holes in failry equal distanc at the edge of the port using #61 drill

I had then taken the pair of painted toothpicks and marked the required length to which they need to be trimmed to meet the required height.

Once the toothpicks are cut to size, I just pushed them through the holes that I just drilled

And finally when both are pushed all the way through, I got a pair of bitts

Once all the bitts are 'nailed' down, I did half the mooring for the largest ship on my layout Betelgeuse - just the bow line and one of the springers. The Stern line and the other springer will be moored in due time. The water level is pretty 'low' and looks pretty 'solid' to ensure that the stern of the ship doesn't start drifting towards the upcoming boat yard. After all, there hasn't been any serious accidnt in Wrightsville Port for last 5+ years though none of the boats had mooring on them all this while, so it is, truly, 'cosmetic'

Trying out my new camera!

This not really is an update on the layout as much it is about my new camera - Sony Nex 3 Mirror-less. With my astrophotography bug forcing me to do modifications in my Canon 1100D and making it virtually non-usable for anything else other than astrophotography, and my aging Fuji S2000HD, I desperately needed a reasonably priced option that caters to all my photography needs, including light astro-photography - hence Nex 3. Old enough to be reasonably priced, small enough for travel and casual photography, interchangeable lens to get the benefits of a DSLR - all in all a good deal for me.

Now enough about the camera intro - let's see what it can do in terms of model photography.

Here are some shots - taken real quick using the smart features of the camera and some with full manual settings. I might need a macro lens, but as a start, this camera definitely have the potential to take good miniature photos:

And then there was time to test the videos. Now this came to me as a complete surprise, but this camera's video features are better than many dedicated video cameras! Video is synched with the still photography mode (If you are taking still photos using smart setting, the same settings will apply to your videos, if you are using manual, then you can set your video settings as well), giving you a wide range of options to adjust aperture, ISO, gain and other setting. So here is a video of the layout taken with the same camera.

Now something about the sound - this is a Train Tech Sound Capsule installed as a over-sized load in the depressed flat car. This is a truly plug and play - battery operated and motion sensing. The sound sequence is pre-programmed, so you cannot really make it sound the way you want, but with a little practice and variation of speed, you can achieve decent sound simulation. This is a very good way to add sound to any DC layout - no wiring, expensive DC sound units or sound cars. For HO/OO this thing is very easy to conceal in any carriage (it actually is meant for OO scale), you have to be creative to make it fit in a N scale car - easiest way I found is to use it on top of a flat car as you can see in the video.

Grain Facility Continued

Had some progress made on the grain elevator in last couple of days. The conveyor belt is now complete, and all the components are now painted. The facility is more or less done, requires just a loading chute for the barges, some grain on the open part of the conveyor and a barge full of grain!

Grain Facility Contnd.

The next step was to add the shades at the end/joint of the each conveyor segment. I had simply cut the appropriate sizes of the corrugated sheets, painted them, and glued them using model cement. Given there are no removable parts, I just used the existing structure as reinforcements for these structures and didn't really waste any time creating reinforcements of their own - after all time is short!

The next phase was to create the hopper car loading facility. Here, I need to mention that like most of  my other structures, this one will also be removable to aide easier maintenance down the line. So, I made a simple structure using the corrugated styrene sheets and glued it to the edge of the concrete base of the coveyor structures using additional cardboard reinforcements and small ABS pillars - this structure doesn't really have a base and when moved will be held in place just by that one edge.

So, here are some photos. My aging Fuji camera is not really in best of its abilities but that's the one I had right on top of the layout - so, just took some quick shots - you have to excuse that extra noise.

The remaining pieces in this facility are the conveyor section to connect the HAC and the elevator tower, connecting the rail car loading section to the elevator tower and finally building the barge loading arm - and of course necessary painting and weathering. Given I will be on vacation the whole of next week, I am assuming this would take at least 2 more weeks to see completion.

Grain Facility - Contnd.

The next step in the conveyor belt portion was to add the 'stairway to heaven!' Pretty straight forward - glue the Plastruct stairs using model cement, and then add the railings. I have used small styrene pieces as the top floor and landings, and some spare parts from the trestle kit to support the first landing from the floor.

The next step was the time consuming painting! However, I have moved away from acrylic in this one (because my matt medium stock is over) and decided to use leftover paint from one of my airfix kits that I built a few days back (A Messerschmitt Bf109 for interested souls). As you can see the humbrol enamel paint does a fantastic job even without an airbrush. I have never achieved this finish with acrylic using paint brush.

as you can see, the wires for lights is in place as well (actual lights yet to be installed).

The Grain Facility

I finally forced myself to take some time out to engage in another intricate project. It's going to be 5 years in this November that I started with this layout, and now I really want to see this finished as early as possible. Well the fact that I have been saying that for last 3 years sort of indicates how realistic that is going to be! :)

Anyway, so among the major items that are still pending, I thought of taking up the grain facility as the first one - it's already half done, and is actually the biggest of all the facilities, so finishing it will be a major milestone.

So as you have been seeing for last about 3 years, the silos and the elevator tower is already in place, so is the small pneumatic unloader. To refresh your memories, here is the build description of the unloader:

Now, given the extremely constricted space available and the fact that the rail line goes in between the unloader and the elevator/silo, I decided to approach the model in a little different way - simulate the elevator tower just for the output to barge and hopper cars, and use conveyors for input to the silos.

This required a High Angle Conveyor, or commonly known as HAC. The operation can be visualized as the barges bringing in the grain will be unloaded by the pneumatic unloader, place on a horizontal open conveyor that takes it to HAC, HAC lifts it to the required height, and then another low angle usual conveyor takes it to the silos turning it nearly 180 degrees. The elevator mechanism required for loading barges and hoppers can be imagined to be inside the elevator tower.

Now leaving the technical pieces aside, here are some photos of the progress so far. Due to lack of time, I am not taking photos of each step, only building milestones. Here are a few photos of the HAC progress so far.

Materials are primarily styrene sheets (Yes, a change in my approach from paper for once) and left over runner material from my old trestle kit - after all, I had to use some scrap material to do justice to my approach!
