Re-usable, just put it in hot water.

Interesting! I might give it a try. Intriguing to see the Fringlish translation - makes a change from Chinglish

Had a first attempt at creating a plaster cast sheep load. I suppose it might look OK from several metres with eyes half closed. I might try another one with the sheep bunched more closely together - ie mostly backs and heads with minimal gaps between the sheep. This is actually quite tricky as when a new sheep is pressed into the moulding medium (ie PlayDoh), it squashes the impressions which have been made previously and they become mishapen and I end up with humpty backed sheep. However, for a first effort .......

The casting - don't look too closely at their faces - a bit scary! .
The load inserted. I suppose it looks a bit better inside the wagon .

Good try Rik, but they do rather look as though they are swimming in a mobile sheep-dip tank!
I think you're right though, there aren't enough of them.

...... or swimming in something worse .....

Does anyone have an Accucraft sheep wagon handy? A chap on another forum has offered to produce resin case loads of sheep backs to fill them if I pass on the dimensions. I've given him the dimensions of the IP Engineering wagon, but it strikes me that the Accucraft wagon is the more likely candidate for loads of sheep.

The latest on this. Yesterday, I received a parcel from Philipy containing three clusters of 3D printed sheep. .
Before sending him a series of photos taken from various angles, I had arranged them on a baseplate of corruflute which was exactly 1/3 of the area of the wagon. Unfortunately, I didn't notice that some of their snouts and bums were overlapping the baseplate and so Philip had to reduce them in size slightly so they would fit. He even printed one set in reverse to try and overcome the regimented layout. The threesome fit nicely in the wagon, with a little bit of spare capacity for another couple of sheep. .
Of course, they need painting which will make the baseplates 'disappear', but I am delighted with the outcome. A lot more realistic than my blobby plaster cast version. .

Just the ticket Rik, and well done Phillipy for coming to the rescue!
I have become a 3D print addict, although not clever enough to be able to do it myself it has opened up endless possibilities for us model makers.

They don't look too bad in the wagon, Rik, I'm looking forward to seeing the painted versions.

For anyone interested, Rik sent me 50 pictures of the one group of sheep, taken from all angles, and I then used some free photogrammetry software to create a 3D virtual model in the computer. This was then transferred into Blender to do a file format conversion, then into Sketchup to tidy it up, then into the Slicer program, and then in to the printer!

What a great team effort. Well done to both of you, that the end result of a series of photo's is this remarkable solid end product is amazing. Peter's right 3D printing has certainly changed the face of modelling.

And me...

Just wish I was the same though Peter. I just get lost with all the tech involved with 3D printing. Brilliant job done from both Rik and Phillipy.

Very nice indeed - I'm very impressed! Well done both of you!

Say what now???
Tis magic Baldrick - let's not worry our pretty little heads over it.

I've now painted the 3D printed sheep which Philip kindly did for me. I think they look pretty convincing.... . .
I also decided to see if I could improve on my plaster casting - I bought a kilo of plaster and I'd hate to see it go to waste. . . .
I bunched these more closely together and I think it's an improvement. But I don't think I can match the 3D printed ones.

Rik

I like the paint jobs, all very realistic to my non-agricultural mind.

Your plaster ones look Ok but a bit too regular in arrangement, I think.

The next batch are in the works!

The printed ones are better but when running on your railway they are likely to go unnoticed, especially from a distance. A huge improvement over running empty wagons which might show no obvious purpose.

I know nothing about transporting sheep, but would you expect them to stand distinctly, because they're soft and fluffy would they not merge into one big white mass with multiple heads?

Sheep would have been almost totally wedged in to stop them moving around too much while being transported, they do tend to look like a woolly mass with a load of heads (my best mate is a sheep farmer)
