I have just added a feature written by Adrian Nyffenegger about how he made a cobble stone street for a diorama.

Please take a look at Adrians technique here

Great feature.

The only thing I a worried about: I heard that the lentices have the habbit of succking up the moisture and then swell up and/or rotten?

I had the problem with them swelling on my first diorama. It was odd though as I coated the cobbled surfaces with 50/50 glue and water and that didnt make them swell, it was when I rubbed the wall spackle between them that made them swell. This technique should do away with that. Cheers Kevin

Adrian,
cheap, easy and effective!!! Thanks for sharing.
Ciao

Wonderful information.... give us an update in 6 weeks about the condition of the beans!

i believe that 1-2 coats of a hard floor 2 parts varnish that dries in a minute will do the work and seal them for drinkin water !!!!

Hello guys

Thanks for your coments.
The diorama is now eight weeks old and the lentils looks like new ones. They didn't swell up.

well now all we can do is try it by ourselfs... But is with out a doubt a fine tecnique...

See yaaa

When I was a lad we used to bake "conkers" to make them hard. Very low heat and a very long time. It dried the horse chestnuts out completely.
Just a thought...maybe the lentils could be treated the same way and when coated with varnishes it may help prevent swelling?
Or once baked spray them with the varnish prior to assembly...??
They look too good to be ignored.
Cheers

Great feature !

Let us know how the lentices do in a couple of weeks. I don't think they will cause a problem, but I would like to know for sure.

Hai Danny,
I have used on my dio lentils for about two years ago. I filled the space between the lentils with plaster of paris. Verry wet stuff. Then i airbrushed them, drybrushed them.
There is still nothing to see of rotting or something else.

I have tried my self a couple of lentis/cobblestone with success but: I an not sure they in 1:35 scale! I have seen many, both round and square, cobblestone pavements and usually you have about two or three cobbles under your feet. I then saerched for children pasta and found a small cilinder size type. I builted a container with cardboard stripes (the size of my road) and filled with the pasta. Then I laied on top a stripe of (white) pre-glued paper: very, very gently! then pressed the paper. After it dryied I turned it up side downs and put in place.
I rubbed the surface with a thin layer of plaster and painted. To me it looks more like in scale! dedox.

Another method that i have tried that does excellent scale is BRASS "BB's".... like the kind you would use for an air rifle. Spread them out on a sheet of sponge tape, press them into place, When everything is dry, I hit them with a coat of white flat primer, and then fill the gaps with spackle. Once everything is dry, i come pack and do my washes and touchup paint.

The scale seems quite perfect (smaller stones than lentils), and you never have to worry about anything! Cheap too!

The lentil method looks great, but I've got an alternate suggestion that might work also. Check out "Drywall for modeling" on the Scratchbuilder's Forum.

Thanx,

Very nice! Now where can I use that? Maybe on my next Sherman project. Thanks for the tips!

I did the lentil trick here at home..my first try. Here is how it went. No shellac/varnish. I had a bag of dried lentils from the market. I layed the lentils on a 100% white glue "mastic". Then I over washed them with a sandy/acrylic tinted 50/50 white glue/water "grout". At this point, the thin shell of the lentils shriveled up, some simply popping off, most shriveling. I used a damp scrubby sponge (scotchbrite) and scrubbed 75% of the wrinkled shells off. The rest I could not remove. I overwashed acrylics with assorted techniques to bring back color. As of this point, 1 week, all is well.

Now a bit wiser, I would suggest a long low heat to dry them completely, then possibly "shuck" them somehow. Hairspray them, the hairspray acts as a varnish, and should probably be sprayed on the beans before they are placed. Shellac is also a good idea because it is alchohol based, and can be painted with water based paints. I definitely will shellac them before I "grout" next time.

There was an article similar to this on Doc´s dios. Looked really well when done. I tried it, but used the lentils with skin on them. Needless to say when the wet grout hit them, it softened the skins and they lifted. After placing maybe 1000 lentils on double sided sticky tape, I was a tad upset, to say the least. So remember ... use the skinless type.
I have a smaller vignette where I used this method again. After 1.5 years it still looks perfect. Even if the lentils rot ... the plaster and paint layers keep them contained and shouldn´t be subjected to the abuse that would break them in.
Good article Adrian. This subject has come up several times and now theres a well explained article to show folks. The dio turned out stunning as well!

Hello guys
Thanks for your interests on my feature. The dio is now 3 months old and the lentils looks still good. I think, it will be stay like this.
