D50 continued

A little while ago I posted some progress I made on a DJH 50 class chassis I was building, since then I’ve completed the chassis and assembled the bulk of the body leaving a few little detail parts and piping (really looking forward to this!!!) to complete. There were a few parts for the model I was not very keen on the main ones being the headlight, shunters step and smokebox door.

I was able to get some replacement parts that looked a lot nicer than the supplied parts from Casula Hobbies during my latest trip down to Canberra, those being a Classic brass shunters step, Ozzy brass loco headlight and a Kerroby models smoke box door handle. The original smoke box door handle I used previously on a 53 class kit never looked right, and when compared to the Data sheet it proved that I was right and it was under scale for the later versions of the loco but is fine for the earlier and flatter smoke box doors.

 The other two parts I replaced where a lot more fine and detailed than what came with the kit but other than that its not as noticeable a change as the smoke box door handle

Anyway now i guess I will need to get the motivation to do all the pipes and hand rails then fit a decoder and stay alive into the tender!


D50 and a Z19

For the last couple of weeks whenever I was doing a bit of modelling it had been on some R car sets and a L set and I decided that I needed to do something a bit different to have a bit of a break from them, The result was I dug out a D50 class DJH kit I had and then a Berg’s Z19 of my fathers which needed some work done to it.



This is my second build from a DJH kit and like my first (a 53 class) I’m fitting a Highlevel gearbox as per an article by Alan Templeman in AMRM #270. I must say after doing one previously this one is going together a lot nicer and will run smoother than my first attempt and I’d hope it would with the amount of hours I spend on the piston and connecting rods. Below are pictures of my progress the third one showing the Highlevel gearbox fitted to the chassis.

When I was painting the D50’s chassis ,I thought it was a good chance to test out a sandblasting chamber I made with my neigbour late last year. The Candidate was a Bergs 19 class of my fathers that had fallen to bits when the models protective paint job was stripped off many years ago. (most likely before I was even born!) It wasn’t in the best shape with bits fallen off and the brass itself being very tarnished, I should have taken some pictures of it before I started but I was just to keen to get in and have a go I forgot too.

The chamber worked really well and got the Z19 bits looking brand new almost, with the fitting of the parts that fell off It was a good time to replace the funnel and dome with a pair i’ve had for a couple of years that I got off John Sever who makes the Ezi Kits range. The ones that came with the bergs model are not the best the dome is slightly dis-formed in the center and the funnel looks just plain wrong (and isn’t the only thing that looks wrong on the model one more being the firebox extending into the cab to accommodate the motor).

Ive got a few more bits to fit back on to the loco, (compressor, headlight, whistle etc and some new buffers to replace the old ones) then I will give it a coat of primer and put it away for a little while until I get the Baldwin low sided tender to go behind it, I will number it as 1919 and it will make a good companion to the other Berg’s Z19 of my fathers the Thow cutaway cabbed 1957 which also had a low sided baldwin tender behind it.






400 class railmotor


In my previous posts I had been working on a 400 class and making a mech for it, The model is all assembled with the SMD’s fitted in the headlights and radiators fitted, it is ready for painting but as It has been back dated to around the 50’s so I can paint it Tuscan and Russet I need to make up some buff decals for it before I progress any further so until that happens its packed away safely.




and now for something different

Over the last two months I have not been able to get much modelling done apart from the 400 class mechanism, that being said I spent in total 4 weeks back down in Canberra casting up some bits and pieces. I was able to finally get some molds made up of some patterns my father has had up for around 6 months just waiting for me to get around to doing some casting.

along with these buildings my father was also working on some other patterns which included FR 1643 and BR 1719 which where the two R cars which where from converted elliptical roof dog box carriages and I was able to start on a pre production FR 1643 which I also fitted a pair of SJM compensated 2AA bogies.

Finally to do with my 400 class posts earlier I’ve decided to do it up in tuscan and russet when the time comes, which means that I will need to make up a solid pilot for the model as believe they where replaced with the strip metal pilot when they where painted indian red. Anyway I’ve been working on sculpting one up to try and get the proper shape which i’m finding it harder than I though but here is a picture of the progress.


slowly getting there, still alot of work to do


Making a mechanism for a NSWGR 400 class railmotor continued

Continuing from my last post with the mechanism almost completed I fitted the PCB and wired it up.

At this stage the wiring is a little bit crude but I will fix that up once I get a chance to drop into my local Jaycar store and get some better wire. Using a Bachmann doodlebug PCB board I had spare, I removed the globes that came attached to it and fitted some integrated sockets so when the surface mounted diodes are fitted to the body the mech can be removed. The board fitted straight over the motor which was convenient as I didn’t have to make any modifications to it and when fitted there was enough room in the body to accommodate it.

For the lighting which I decided to fit to the mech I used some 0603 surface mount diodes which I purchased a while back from a eBay store called bright components, surprisingly they are not that hard to wire up!! I have a jig that I use to hold them while they are soldered up without it the process would be much harder.


The SMD with 1K resistor soldered onto the + wire and fitted to a integrated socket

After the SMD was soldered up with some magnet wire I attached a small 1K resistor to the positive wire then fitted an integrated socket to the ends so it can plug into the PCB on the mech. I was able to get everything wired up and took the mech for a test run on my short section on test track and It preformed really well, now time to finish off the body so I can properly mount it.


Making a mechanism for a NSWGR 400 class railmotor

A little over two years ago I purchased a Bowser mechanism to have a go at modifying it for a railmotor as a good and relatively cheap alternative to using a SPUD to power one.

The original mechanism was a Bowser #125144 (mech for old Bowser brill) which needed to have the cast metal chassis cut up and the wheels replaced with ones of the right diameter and a bit narrower. For the chassis to fit properly the ends had to be removed to get the bogies closer to the ends of the body and also the trailing bogie section had to be removed to get the wheelbase right.

As the wheels where the wrong diameter for the 400 class they had to be replaced with more suitable ones, around the time I purchased the mech I also got some half-axle NWSL wheels (NWSL 37245-4 36″) which the old ones where swapped out with, as the old ones where also half axle wheels this was very easy to do.

Once I determined the spacing between the bogies I used a piece of K&S brass bar (105mm X 12.5mm X 1.5mm) to attach the seperated parts of the chassis together which will also help with fitting it to the body and have it easily removed if needed. It was fitted using 8ba screws through the motor holster mounting holes and also fitting a 8ba screw and nut through the trailing bogie along with superglue to help make a strong bond also epoxy would have been better.


The Mech fits snugly into the shell, the die cast chassis was the correct width and didn’t require and filing, now I just need to the the correct height and decide how to fit it.

Finally as I wish to fit directional lighting to the model I will modify a Bachmann doodlebug PCB which I had spare from another mechanism I modified for a Silver City Comet. This will probably just involve the replacing of the bulbs used in it with some surface mount diodes and maybe the resistors too but that will be done after Im happy with the fitting of the mech.
