Hi everybody,

I would like to construct the farmbuilding on the picture below and I would like to show the stony texture of it. Does anyone have suggestions which materials to use to make this in 1/72 scale?



Thanks!

Jelger

Hi there,

Cork is the way to go......(oftewel...gebruik kurken onderzetters van de AH die je plakt op karton)

In 1/72 I'd go with a plaster.
I'd make a mold out of coffee stir sticks and a thin layer of plaster. As it dries I would dab it with a sponge to push some texture into it. Then I would use a scribing tool and etch in the brick work.

Also simple glue can be used for this. I saw this technique in a great build-log by Claude Joachim

Hi

Because you are at 1/72 scale you'll find a lot of model railway stuff will fit the bill when looking for diorama supplies. One company Slaters make embossed sheets called Plastikard. Check out railway hobby shops near you.

Here is their web page

Everybody thanks for their quick replies. A question about the plaster, is a thin layer of plaster strong enough? The front wall of the building will be 8cm x 20cm.



Jelger

You can either pour a fairly thick layer of plaster or you can glue the plaster to a piece of plastic card (you could even use a scrap piece from a piece of packaging from a 'blister pack').
You can also embedd strands of wire in the plaster extra stir sticks to give it more strength.

Hi everybody,

I chose to go for the plaster and try with a fine sponge to make some texture in it. Tonight I started to make the mold. When I proceed to the pouring of the plaster I will make some progress pictures of it, which will I post over here.

Thanks again for your advice!

Hi everybody,

here are some pics of the results I achieved with the plaster:

This is the simple mold I made according to the reference picture:



Here is the result with the plaster poured in:



The next step will be the removal of the mold, together with the wooden sticks. I don't know for sure to scribe in any stonework. I have a bit of a feeling that the current result will work too, but please give your opinion. The next step will be cleaning up the wall. After that I will put on some modelglue to cover the wall as cleaning up will probably result in some rough areas were the plaster is broken and with glue I hope to get an even surface. With the glue I also hope to have a good basis for acrylics to spray on.

Every bit of advice is always welcome so please shoot!

Hi Jelger,

This is well done, doing this small one without breaken it is already an achievement.
Pay attention to always have a flat surface under it, otherwise you will break it in a nanosecond.
I don't think it's worth scribbing in stonework.
You will anyway have big problems doing so because of the danger of breaking it and the irregular surface it as now. If so, you should not have done the sponge pattern.
You need to pay attention regarding scale. The elevations of your pattern may already be out of scale. A 1 cm granualrity in real life (and that's a lot ) is only 0.72 mm in your scale.
My advice: Work on it until you are satisfied, whatever pattern is in at this moment.

Regarding the surface to paint. I am sometimes using a sealer for plaster but also acrylic paint. Apply a basecoat of diluted acrylic paint (Buff/Deck Tan) , this is a good enough seal for the next coats . Glue will make you a flat and shiny cover difficult to work on.

Cheers

Claude, thanks for your reply and advice,

Yesterday i removed the mold and yes, the wall broke in two pieces. Fortunately, the breakline was quite clean. From the mold i made a supportive structure which is glued with superglue to the wall. I will use some diluted plaster to improve the wall and to clean up the roughest parts. After that I will add the wooden frames of the doors and windows. Sealing with diluted acrylic paint will be done after the wall is made to my satisfaction. I will post pics of my
progress.

slaters are o.k but wills are far superior in any case if using model railway plasticard items the scale you require is refered to in 3 ways HO , OO or 4mm

heres a link for wills they also supply items like windows etc for scratch building
