8F progress

I’ve been working slowly on the “motion bracket” and the slidebars and crosshead assembly, toghether with some of the valve gear.

Here are some pictures of the progress so far:

A few notes of explanation.  The first shot shows the laminated rods, with bifurcated ends to allow joints with other pieces of valve gear: see the union link in the fourth picture (parallel to and below the cylinder slidebars); the expansion link is the curved piece through which the radius arm travels.  In most models the radius arm is left in a neutral position, thoguh the centre of the expansion link.  This is convenient, as the centre of the expansion link is the pivot about which it moves forward and back, but for the radius arm to be there is to have the model always in neutral gear.  So instead I am making my model in a forward gear, with the radius rod just below the central expansion link.  The radius arm will move forwards and back a very small amount as a consequence, but the construction should be able to be done reasonably easily (I think).

It’s possible to see this in the pictures if you look closely.  I had to create a pivot for the radius arm just below the central pivot of the expansion link.

The whole construction is made to come off the frames for ease of maintenance and building.

Not complete, of course.

 

Melbourne

I’ve been in Melbourne this week, at the World Congess of Cardiology.

Melbourne was cold and windy, as you might expect.  There are some mitigating features: trams, passenger trains hauled by locomotives (even if they are all Diesels), and I was once again struck by how much room and space there appears to be in near-Central Melbourne, compared with Sydney.

However there is also the casino.  This is truly horrible.  As well as the casino itself, there are at least four huge self-proclaimed luxury hotels attached to them, and they are all glitzy and to my mind deeply unattractive.  Even if you like “glitz and glam”, the concept of exploiting people’s complete lack of sense is morally dubious, to say the least.  No-one who has the slightest appreciation of the arithmetic of statistics can fail to understand that casinos or poker machines (aka One-armed Bandits) are a simple way for owners of casinos or clubs to make huge amounts of money from the gullible public.  The whole industry that has been allowed to grow up around this exploitation is appalling.  I understand that ideologically people should be allowed to make their own choices.  Nevertheless this transfer of wealth from the poor (who do most of the gambling) to the rich (who own the clubs and gambling houses), without even a decent amount of government taxation to reclaim some of the revenue to the state is definitely a case for government intervention.

The conference was good.

Autumn in Mount Riverview

It is a lovely autumn morning here in Mount Riverview.  Easter Friday, in fact, and so it is very quiet also: much less movement.  Almost no sound except the birds in the bush.

Website Mt Riverview 3

The sun was shining in almost horizontally as I entered the Middle Room.  So I went out with the camera into the back garden.

Cockatoos screeching, rozellas piping, kookaburras laughing.  it was lovely and quiet (!)

 

 

A couple of pictures looking back up at the house:

Website Red and Blue Polos 2When I went around to the front, the garage doors were open.  We had to get different coloured cars, so that we could tell them apart ….

 

 

Website Red and Blue Polos 1

Actually not so really: one is Diesel-powered, the other petrol-powered, and they are quite different to drive.  Andrew and Nick both drive the Diesel more, and much prefer it – I think it is easier to drive at low speeds around the town, because it has so much more power (torque?) at low engine speeds.  Better for learner-drivers like Andrew, certainly.

Stanier 8F in Scale Seven – first post

I have started to build a model Stanier 8F locomotive in 7mm scale, 33 mm gauge – Scale Seven.  It is a Modern Outline Kits model, and Dave Sharp, of MOK, is being very helpful: it is a kit made for “0-Gauge”, and he is making a special conversion kit, to allow construction in 33mm gauge (a prerequisite of S7) with widened frames (29mm outside width).

Frames in construction: the spacers between the frames have been soldered to one frame only.

Frames in construction: the spacers between the frames have been soldered to one frame only.

So far, the kit seems extremely well thought-through.  The conversion kit works well so far, also.  Correct frame width in 7mm scale would be 30mm O/D, but in discussion with DS, he and I agreed that to do this would leave so little room for manoevre that it would make the kit very difficult if not impossible to make.  This kit appears to have the girders and plates between the frames made to scale as far as possible.

There is an elaborate method of “compensation” – a mechanism to alow the axles a limited amount of up-and-down movement.

 

 

Frames together: if you look carefully you can see the blobs of solder on the nearer frame.

These are the frames put together, all “squared-up”, but so far with solder only on the one frame (just visible as blobs on the outside of the nearer frame – I will have carefully to flatten them after construction, and there will be only about as millimeter between the frame and the inside of the wheels.

The kit clearly has the potential to make a superb model of this freight locomotive.

Medical Students

Hmmmm.

Nick has been a medical student for a few weeks now.  This has had numerous expected and unexpected consequences.  As a result of him being a student at UWS in Campelltown, he has to drive about 3/4 of an hour to get there.  Public transport is not really an option: he’d have to go Blaxland-to-Granville (about an hour) then Granville-to-Cambelltown (also about an hour).  So he has been taking the blue Polo.  For his first two weeks at Uni., I rode to work every day, and decided to make a virtue out of necessity by setting myself a challenge.   All ten working days I rode on my bicycle all the way up the Old Bathurst Road without getting off!

However the consequence of Nick having to drive to work was this:Red Polo small 1

 

 

 

Yes our diesel Polo is blue.

I decided that we had to have a third car.  Nick can use the diesel Polo (about 5.1 litres/100km) whilst I will part-time drive to the hospital in the new car.  I looked at a Hyundai, a Subaru, etc., but VW had a special deal on the Polo, so we bought the cheapest Polo that you can get in Aus.: a 1.4litre petrol-powered one.  It still drives nicely and is nice and quiet.

 

Just for amusement Nick took it to Uni., and one of his friends said “I could have sworn that your car was blue ….”

What is more important is that Nick seems to have settled down well.  There’s a lot of work, and it’s very different from school, but he seems to be coping OK.  There’s a lot else going on, and he is making the most of it, I think, which is good also.

 

Japan and Korea

SMALL Hanazono

We have just returned from what has become our annual trip to Japan – to Niseko in Hokkaido, to go skiing.  We also went to Korea on this occasion.

 

Japan first.

 

Here are a couple of clips of Andrew and Nick skiing:

<.avi files> – Andrew skiing  : Nick skiing.            …… Double-click.

<.wmv files> – Andrew skiing 2  :  Nick skiing

We were in Niseko, as previous years.

SMALL View from Shiki Niseko 3Over 2 metres of snow fell whilst we were there.  The skiing was good, therefore, but the visibility poor.  Some great times, though.  Great restaurant meals and good family time.  Andrew came up with a good new description of the way our family runs: “Our family is a democracy, but Mum has three votes, and decides on all ties”.

SMALL Meal in Iki Restaurant

 

Great food, some superb restaurants, including “Kamumura” and “Iki”

 

 

 

 

Previously I have known little of Korea.  A little from M*A*S*H, a little from other sources, but really not much.  Now I know a lot more, and have a great appreciation for the Korean overall.  A culture which seems to blend the best of Chinese and Japanese, although Koreans might say that they were the originals, with some justification.

SMALL Gyeongbokgung Palace front gateway.

There are many old buildings found even in the centre of Seoul, as this view (of Gyeongbokgung Palace front gateway) shows.

 

 

 

The history and culture are terrific, and the scenery beautiful even in the middle of winter.  This view was taken in the Suwon Hwaseong Fortress, a day outing from Seoul, and an UNESCO World Heritage Site.

SMALL DMZ family picture 2

 

We also visited the “DMZ”, or Demilitarized Zone, between North and South Korea, and learned how 85% of all Koreans want re-unification (although at least 20% want some adjustment of economic status first!).

 

SMALL DMZ Steam Loco

 

The scars are still raw, it appears.  This is a steam locomotive stranded in the DMZ at the cessation of hostilities.  Actually there are over a thousand bullet marks in it from before firing ended, and I think it is unlikely to move again under its own power ….

Christmas and Birthdays

david, andrew, mark, nicholas and sue at blackbutt circle

We have, this year, nearly had all the family together for Christmas: in early December the two “uncles” were in NSW [Mark and John], seen here in the courtyard at 33 Blackbutt Circle.

 

 

David Andrew Mark John Nick at 33BBC

This meant  that all five of the male Coulsheds who feature regularly on this website were together for the first time in several years.

We had a form of Christmas Dinner together, using the Royal Worcester Evesham dining set that had been collected by Olive Coulshed in Liverpool, and now is kept in Australia!

Christmas at MtRiv

However the real Christmas Dinner was held with the Nicklin Grandparents, on Christmas Day – although we used the Evesham on this occasion also.

 

 

Andrews birthday 2013This has also been the season for birthdays, of course.  Andrew’s was first.  Here he is, lighting all the 16 candles, with a catering blowtorch (of course).

 

 

Nicks 18th birthday 2013

Nick’s was a larger party.  Not surprising, given that it was his 18th Birthday Party.

We are lucky: our house, especially the “Middle Room”, is just made for entertaining!

Mark and John in Australia

John and Mark in BM National Park 2

John and Mark in Blue Mountains National Park (near Glenbrook, NSW)

Mark and John have recently been with us in NSW, having spent the previous three weeks in New Zealand.

The first couple of pictures were taken on the day when we visited the Blue Mountains National Park, which is less than 10km from our house in Mount Riverview.  We went to Euroka Clearing, hoping to see kangaroos in the wild, but they weren’t there (apparently this clearing is becoming too busy with tourists camping overnight there, and they are not as commonly seen as they once were).

Mind you, M&J had seen the wallaby which comes to visit our garden sometimes in the early morning, so at least they saw some native fauna in the wild.

Garratt at Canberra

The fully-restored NSW Garratt at Canberra Railway Station

We also visited Canberra – Mark, John and myself.  Being train enthusiasts, we went to the  NSW train museum on the way down (at Thirlmere) and then visited the Canberra Railway station, where they have restored to working order a standard-gauge 4-8-4+4-8-4 Garratt.  A truly gigantic angine, which will be such a magnificent sight when pulling trains once more.  Actually it is magnificent just standing there ….

Wildfires

There have been lots of bushfires in NSW recently, including one which could have come right up to our house.  Fortunately it did not, and the danger is now largely passed.

In fact we are well-prepared, with a system set up with a pump to spread water through a sprinkling system all over the house.  We have worked out what to take if the fires really require an evacuation, and we have put shutters over the more exposed windows.  The pump would be set going and left going after we drove away.

Firemen in the back garden

Four days ago the wind was strong, and could have blown the fire in our direction.  Since then there has been relatively little wind, and the local fire service has undertaken a “hazard reduction burn”, which means they set a fire going, with lots of firemen around to control it.  They have largely burned away the undergrowth and leaf-litter around our valley (the valley behind our house).

This will greatly reduce the likelihood of a wildfire reaching our house, so it is really good news.

Sue and I were approached by a reporter/presenter from Al-Jazeera – the 24-hour news channel run from the UAE.  Sue gave a “live feed” intereview, and they recorded a short segment for a later broadcast.  It’s on their site, so here is the link: …………………………………………………..

The two people in the “crew” spent several hours on their Apple Mac-Books at our dining table after taking the film, editing it all to make just a 2 min. “clip”.

After the controlled burn

This picture shows the area of bush just below our garden the following day.

The area of bushland looks devastated, but it isn’t as bad as after a spontaneous bushfire, because the trees above about 3m aren’t burned.
