A well thought out solution to a tricky section of the train.
Looking great Charlie.
Cheers
Trev.

Almost at the end.
Just remember that under the bunker is water space. The railways tried to carry as much water as possible, sacrificing coal space.
Are you going to have coal in the bunker, or have it empty as per the museum?
Keep up the great work.

Hi Kevin,
Thanks.
Still a bit to do - the tracks, ballast, etc
Was going to add coal, but make it a solidified mass so I can remove it. (I will make a form the same shape as the hopper and then saturate my "coal" with 50% PVA glue 50% water - will take a number of days to dry solid incorrect shape) The base beneath the coal where the water tank is located it going to be a switch box for my "fire".
Will be sad when the D4 finishes but really looking forward to the "K" Class. It will be a long but enjoyable build I reckon.
(I will have to start looking for space to store it - but will have 12 to 18 months I suppose)
Regards
Keith

Train is looking fantastic.
Job a good one Keith. Do you need to do the same for the sides of the bunker if so use the same set up but do both at the same time screwing each at 180deg to each other will stop the out of balance problem which will mean you can speed the lathe up and get a better cut. That is if you want advice from a novice.

Thanks Derek,
Hadn't thought of a counterweight - stupid me. No I don't need the sides the bunker has straight up sides so that makes it fairly easy. There is still a small vertical section that goes above the curve at the back. I will handle that with dowels into the moulding and the MDF.
Will use the sides to support the back "odd" shapes (thanks for suggestion Trev). Happy with how it's progressing.
That bowl you have just posted in General Woodturning is pretty good for a "novice" Derek - Top stuff
Regards
Keith

Keith, here is an idea. Rather than having the coal bunker full (which will block the windows), have the coal below the top of the bunker, so you still have some there but it has been used so the bunker is not full.
There are times when the crew will empty, or almost empty the bunker in a shift so there is nothing wrong with having the level down. Just remember that coal is not round so it goes down first where the door in the cab is.
"...looking forward to the "K" Class. It will be a long but enjoyable build I reckon." Yes, compared to the D4 it will be a long build. Longer in length if you keep the same scale, time wise depends on what happens.

Hi Kev,
Good idea about the coal. Yes - will do that. I was going to keep the same scale with the "K" Class. but need to consider how I can transport.
The tender is pretty long so that will be removable. Really should have bought a transit van as part of model making equipment
Regards
Keith

Hi All,
Can't believe how long it took to get the framework square so I can then add the rear and sides of the bunker.
Wanted to get the sides relatively correct before I do the angled base of the bunker. Still a lot of filing and sanding to get done on the verticals of the bunker, but I'm pretty happy how it's coming together. Only clamped at this stage. Will pull apart again and the do a bit of work on the interior of the coal bunker.
(You will probably notice that the number 268 is not exactly level. At the moment only held there by double sided tape)
There is still quite a lot of detail to go into the coal bunker. Lots of internal rivets, external handrails, running lights and then the buffers and the coupling assembly. There is also a retaining guard to be added to the top of the bunker so any loose coal won't fall out.
Regards
Keith

"...retaining guard to be added to the top of the bunker ..." - hungry bar or hungry boards. Used to increase the capacity of the coal bunker. This could be due to operational requirements but more likely due to a decrease in quality of coal so more is required to cover the same distance. The Na engines used by Puffing Billy were originally built without hungry bars. Over the years more were added, by the 1960's the rear windows were removed and more bars added so coal could be built up even higher.
You workmanship continues to impress.
