Mid-Cornwall Lines - 1950s Western Region in 00

I have no idea what a "sausage sizzle" is, but I want one.

It's a tradition at Bunnings, which is our equivalent of B&Q or such like. At weekend lunchtimes, different charities or community organisations run a BBQ as a fundraiser. The standard serving is a sausage, sliced lengthways, with two pieces of ordinary white bread and (optional) onions. All for $2.50, no extra charge for red sauce, brown sauce or mustard. Not exactly gourmet fare and to maximise their returns most of the organisations use the cheapest ingredients they can find (and why not?).

Yesterday the LM2596 regulated voltage power supply unit arrived, so I stuck the tiny heat sink on to the chip, as recommended, and tested it on the bench.

 

Using the actual 12V dc wall wart that I use for the signal power supply, I adjusted the open circuit output to 1.30V as measured on my very cheap multimeter then measured the voltage across a 5.6 ohm resistor, which was 1.33V.

I then adjusted the voltage under the same load to 1.30V...

...which corresponded to an open circuit voltage of 1.28V.

Finally, without changing the setting, I tried it with an actuator, when the voltage was again 1.30V (all values rounded).

 

It does everything that the supplier said (although I haven't tried it at maximum current yet) so I'm now a very happy chappie again. This has given me the confidence to remove the individual current regulators from the signal power modules and leave them just as relay modules supplied at 1.3V dc instead of 12V dc.

To clarify, the ingredients of the feast are provided by Bunnings, which will explain the remarkable similarity of the offerings irrespective of the community group present.

Thanks, I didn't know that. It must be on a store-by-store basis, as there is some slight variation. On Saturday, for example, we were offered a choice of white or wholemeal bread!

 but I'm never there at a time when hotdog eating seems appropriate

 

 

G'Day Folks

 

With me working shift on the Railways and other jobs in my working career, I can eat any thing at any time, Trifle for breakfast or Sardine sandwiches at 4am, without any bother. Hot Dogs are a 24 hour fare, just like Hamburgers.

That's interesting. When I worked shifts, which admittedly wasn't for very long, I used to eat breakfast-type food after I woke up, lunch-type food during my mid-shift break and a proper dinner-type meal after the shift ended before I went to bed.

A choice of bread?!   Some people obviously have access to a better class of Bunnings than the rest of us!

An old sailing colleague of mine always claimed that his yacht had an adjustable yardarm, so that the sun was always over it.

An enjoyable non-work day today, which I made the most of.

 

This morning I went round to see Rob @RosiesBoss for a look at his extensive collection of scratchbuilt, kit-built and kit-bashed locos, coaches and wagons. Most of these represent something from the Welsh Valleys in the 1930s although he has modelled some other equipment too - not least a kit-bashed Kitmaster 8-car WR Blue Pullman. I was especially interested in his use of such things as Tri-ang Nellie, Bachmann (US) and Athearn chassis for motorising his locos. Thanks Rob.

 

After lunch, Charles @RudderC popped round - the first visitor to the Mid-Cornwall Lines since March. I started with a show-and-tell of the work I've done since our last running session in January and then we decided, of course, to run some trains. Charles chose to work Porthmellyn Road signal box for the first time, which he picked up fairly quickly, while I did everything else - so the gaps between trains were in some cases prototypically long... We ran through some of the sequence, starting from train 79 where we left off in January. By omitting repeat moves for the china-clay trains and the railbus, we finished the Friday sequence (appropriately) by the end of the afternoon.

 

There were a few glitches but overall things went pretty well. It was good to see trains running again and also good to see Charles enjoying a different role from his usual choice of Penzance yardmaster.

 

Back to the banner signal now - I've started painting the signal and fitted the actuator, so I hope to get it finished soon.

 

I'll also be installing the new signal power supply over the weekend - not before time, because another current regulator failed today. I don't think it burnt out the actuator though.

Today I fitted the new signal power supply unit.

I needed to mount it on a backboard with connectors before mounting it on the layout.

 

Next I converted all the existing signal power modules to just relay modules.

These are a lot simpler and tidier now.

 

The only trouble was that some of the signals still didn't work. That's when I discovered that the jack plugs and sockets are only a loose fit to each other and therefore only making intermittent contact. I'll have to replace them with something else, possibly a miniature connector as used by radio control modellers. I'll see what I can find. A bit annoying really.

Some searching suggests that JST RCY connectors might be an economical alternative - any thoughts or experiences to share?

Apparently not!

 

I think I'll order a few to try - they're only $0.74 a set from the same people who do the signal power supply. I'll also see what's in the radio control section of our local model shop later in the week. In the meantime, having had a good walk this morning and planning to watch the Bl00dyslow Cup this afternoon, the most I'm likely to get done modelling-wise today is to finish the banner repeater.

With nothing to do on the existing signals until some decent connectors arrive, and with it being a work day anyway, there was nothing for it but to start another batch - three more ground discs this time (32, 34 and 47), which will complete the main line signals at the Down end. No photos, as it's just the same as last time apart from priming and painting ten etched discs - a full Scalelink fret's worth.
