2018_03_25 A change is like a holiday?

2018_03_25  I'm just kidding I think....

Something different to break up the monotony (of rewiring)

 First of all, a Locomotive that was working on DCC well for a year or two, suddenly starting playing up. I opened it up and found these two devices used as suppressors under Aus law, were still connected. One had burns on it. I snipped them out and replaced the connections with plain wire (ends of resistors)  Problem resolved and engine performs well, probably better than it ever has. Moral of story? cut off these two suppressors and the capacity that sits between them when converting to DCC. The capacitor is removed and not bridged with plain wire.

Strange shorts  STILL!!

I was working on the layout and shunted a train away from where I was working. After the job was complete, I turned on the power and of course, I had another short, shutting down this whole area.
I immediately checked all my recent work, testing as I went. I removed all the plug in droppers but short persisted. I went inside and watched some TV. Several days later, I went back to problem solving. I noticed a new SDS guards van was blinking red lights, so I picked it up to look at it, and the short disappeared. It seems the van was sitting on a diamond crossing. Further when I sat the wagon on the main line it worked perfectly. But if I sat it on the diamond, it shorted out the command station once more. I spent an hour or two testing the circuits on the diamond, which were all good. 8 insulated rail joiners one rail each side to red and Black Bus! and two frogs connected to juicer which was showing appropriate lights. However they failed to change colour when an engine drove through.

Houston we got a problem! Anyway I decided to walk away for a while and look at the guards van. But then I noticed it was sitting on the Wodonga Coal siding SG  track not the crossover. So I placed it on the BG track and the short did not come back. Furthermore the diamond was connected to the SG bus, which should have been ok. I will connect it to the main through bus, and see if short goes away.

The SDS van now does not light up, so I decided to take a break and open it up, and see if I could get it working once again.... pictures?  I remembered to take some :)

CLICK PICS to enlarge

This is the SDS van. Its a beaut piece of work and I liked it enough to buy 4 of them.

Line door up with step to refit body

See two small square lugs? They have to be released to remove body.

On this photo almost to verandah see square attaching point on frame? This sits over lugs inside body!

I used 4 bread tabs to release lugs.

So here is the floor. I found two small screws that release weights sitting on top of circuit board.

The weights sit over the capacitor. The two small black cylinders (One under my thumb) have red LED's sitting inside and need to sit under light tubes for lights on body.

Great design. The steps are soft plastic that push aside without breaking.

However the body plastic is rigid, which means the end up rights are brittle. They have to sit outside the iron work and slot into holes in deck. Be gentle when putting it all back together.

Oh? near forgot the brass tabs fit on top of the bogie screws which are passed through the wheel pickups. The power then routes through the circuit board
 The right hand brass tab fell off, so a coincidence rather than a cause of the short. No sign of heat.

But I still am no closer to finding out why the guards van operates everywhere else, but causes a short circuit in the SG  parts of the Coal Siding :(


2018_03_22 Got some seats...but...

2018_03_22  Casula had some suitable seats for under $10 so I ordered them.....

Chop these up, and repaint them and they should look pretty good with a few behinds sitting in them and lights on top.. Speaking of...

Lighting the carriages stumbled a bit today :(

Unfortunately Jaycar cannot help me with the stuff I need, and I finished up having to go to AliBaba(whatever?) in China. Had to buy 100 minimum order as well ($32 free postage)
Worst part is I am rearing to go, but will be lucky to get the order here for a couple of months, and then I will be on something else, I guess.
According to Jaycar, nobody uses self latching reed switches these days. They wanted me to use an electronic relay instead. About $5 a part ( in lieu of the convenience of a magnet and a 32c reed switch.

As I intend to store my carriages in particular tracks. I thought I might be able to suspend a magnet over track that turns lights off as cars enter siding, or turns them on as they depart. Just noticing though that you might have to reverse magnet to change switch ?? Cross that bridge when I get to it, I think.


2018_03_21 Coach Lighting

2018_03_21 Bill from Dromana sent this to me, and I like the idea, Thank you, mate.

Certainly saves a lot of mucking about with
 wheel pick ups, doesn't it?
How many LED's will 3v light up, then?
Visit Jaycar tomorrow, if I get a chance..


2018_03_19-Little Jobs

2018_03_19 Sound into Class 45 and lights into Harris RM Trailer.

First the 45 Class Sound install. With the Auscision loco fitted  ready to plug in a 21 pin decoder, it was just a matter of plugging in the Wow decoder and wiring in the speaker a 10 minute job.
Remove the couplers and 4 screws, two each side of coupler. Plug it in, and solder speaker wires to tabs marked SP. Screw body back on and test run :D

45 Class takes a run on H.B.N.
Wondering how to fit lights and seats into a DRC and Trailer

I have an epoxy DRC and trailer and I want lights and seating fitted. I bought some seats from Casula Hobbies and they should turn up soon. 

 So the Harris MT car needs wipers for power as well as LED's
 The Trainbuilder bogies are all brass, so I am having problems thinking out how to fit wipers.
The wheel sets are fully insulated, which means the pickups have to touch the tops or sides of the insulated tyres. At the top is a thin brass plate. I could replace that with styrene, and use small plastic screws (presume they are metric and hopefully JAYCAR have the next size down which would allow me to insulate pick ups.

This insulated (nylon) screw is metric, but too large. Intend to replace brass plate with styrene spacer  which would replace small existing spacer used to lift car to correct height (shown in pic above)

Any suggestions to

2018_03_16 Playing with the B.E.

2018_03_16  laying asphalt :)

I got some thin foam from Office Works, and more from a dollar store at Birralea.
Added it on top to see if it looked like bitumen.

So this is what we started with. The white foam is about 2 mm thick and came in 5 sheets, all white.

The black sheet came in a pack of 5 different colours. Only one black sheet :(

 It nearly comes up to rail height. So a track cleaner gently rubbed should clean the head of the rail.

Started to chalk and rub with a cloth after white glue set. I will finish this off tomorrow. I am happy it will work. Also finish off covering the white with black.

Got a parcel from States. I just cannot find things like pallets, workshop machinery skips etc here, got them all in one box. A bit pricy though.

The Parcel?

 Fork lifts, Elevators Workshop machinery such as drill press and lathes Welders etc.

Skips and pallets and hand held pallet lifts. and milk churns for Depot as well as bicycles and stuff such as that.


2018_03_10 Another Sandown and yes I went again

😷 2018_03_10 My Mum saw the TV adds for Liverpool "Of course you will be visiting me then?"

So another promise broken (that is to never go to Sandown again)

Mind you Auscision made it all worthwhile. Meeting friends was another plus.
So others will show you pictures and talk about the layouts.
I will show you the specials I got..

Here is something I found for my mate Al :) Hope he likes it, as it operates traffic lights for crossroads, that is 4 directions using Australian system that is yellow> Red> Green> Yellow and back to red again. (optional bus or tram light to boot ;)

48 ft containers. A bit late for my era, but... I like them

A Alco Class 45 from the Auscision grab bin. Thanks guys, its quiet, complete and runs well DC.

A few more containers. Thanks Bruce Race :) You talked me into them, but I am happy :)

Was never going to pay what they were asking for these, however  they were caught with too many of the early paints, so I picked this one up very cheap!

And a few more cars :)

I also visited Kyneton on the Sunday...

Kyneton Exhibition 2018

One seller had some small packs of Chinese stuff at  good prices

 I will use these to light up the sheds. Paint inside white and top green. Try to remove posts and hang them from the rafters. If that does not work, I will write to the Chinese seller and see if he will make me the shades without the posts? Packs of 3 for$5

5 for $5 Pretty reasonable? includes 15 Led's and resistors.


2018_03_03 Weathering the rail and the B.E.

 2018_03_03  ok Graeme shows me his weathering methods and paints my rail. I continue with the B.E.

minimum masking and using an airgun.

The B.E.

 Its coming along and all I need is bits and pieces to hi light the scene. I have a parcel coming with most of these. Unfortunately the Mobillift crane looks like a scratch build, according to Owen of
