Really nice Les.

 

Thats some 3D design to have all those textures.

 

Can I ask what method you have used to print the building. Is it FDM or Resin?

 

Regards

FDM. Needs a bit of fettling to get crisper detail. Total print time about 200 hours! The outer layers are printed very slowly to preserve the detail of the stonework.

Is the 4 bolt heads etch for the return crank, Seeing where they are on the etch, they have to be on the chassis some where and not for the body.

Found them on the top of the boiler behind the chimney. They are engraved on the boiler casting. I will leave them off as the thickness will be overscale and ruin the streamlined effect. Though you may be right about an overlay on the return crank and I will check the fit on the crank pin next time I work on them. Surprising there are no such etches in the non streamlined kits.

Loco profile no 37 has a works picture of 6225, with the caption commenting that the ventilation louvres were added to the 1938 batch of streamliners, and were therefore missing on 6220-4 (as built). So it depends what number you're modelling.

Just had a look at that. I am doing 6240 which would have the vent. I have already put the front steps on and the works plates!

The tale of three coronations continues. The third of my three Coronations is a streamlined version. I need a bit of help here. The model is a Model Loco kit and the etches contain two small rings with four bolt heads etched on.

The kit I am building has no instructions and I have no idea what these bits are or where they go. The full etch is for the streamlined version so I assume they will go somewhere. Anyone got any ideas, preferably with a photo? Also the picture of a streamliner shows a small vent. This is not part of the kit and I have a feeling an etch is available. Again anyone any ideas? The model is  00 scale EM gauge.

Are you using a single sugar cube or multiple cubes? We know the sound is coming from the tender rather than the loco but it is not obvious when viewing the train or layout as a whole. The larger speaker in the tender gives a better quality of sound. I did think of putting a single cube in the loco as an extra speaker but that means eight cables between loco and tender.

the duchesses and princesses fitted with sound for Carlisle have the dcc chip and speakers fitted in the frames. (sugar cubes fit easily and are fitted to "bounce the sound" down into the track.

 

Speakers in the tender means the tender is chuffing while the loco is silent...

A quick note -  when I try to access the video, YouTube reports it as "private". You probably need to tick a box or summat? 🤷‍♀️

Now public rather than private.

A short video of the very first test run of one of the three Coronations. Not all that smooth yet and I am not happy about the valve rod lifting a bit. Better running was achieved a few days later and will be even better when it is oiled after painting.

The last streamliner was City of Lancaster which wasn't rebuilt until 1949 and actually got its BR number, so well within your time frame.

We had Lancaster before in wartime black. I always fancied doing a lined version. City of Coventry was the last in red livery . That is layout license for us!

Very impressive but where did all the RG4's come from?

We had them in stock from way back!

The final update was to be a movie of the loco running on the test rollers. But is a 20Mb file and is over the limit for RmWeb and I have no way of reducing the file (Steve?). 

All three locos ran as good as can be expected at this stage. Since the roller test I have run them on the layout to assess the sound system. The speaker in the loco is probably the better location, but from a distance it doesn't make a lot of difference. The larger speaker in the tender produces a better sound quality in that the lower frequencies are better. At least with three pacifics the sound will be slightly different with the two speaker types.

For the record we are using Zimo decoders. The tender speaker is a chunky boom box from Youchoos, and the smaller speaker is a double sugar cube, again from Youchoos.

Next is the loco body building.
