Here are the steps of my bridge work for my last diorama 1/35 scale which I'm building for the "seeing red" campaign.
The bridge is from plaster. First of all I decided how big it would be. Then I build a box using cardboard which will be the mold for the bridge. For the aperture of the bridge I used a tube. A deodorant tube also works.

I gently oiled the tube for isolation. Otherwise the tube will cling the plaster, and when you pull it away the plaster will be harmed.
When the plaster is set I saw that it would be nice to have parapets on both sides of the bridge. It would be easier to arrange this before pouring the plaster. But modelling was much more fun

The next step is marking the stones with a pencil. I recommend you to have a reference picture neerby.

Excellent step by step.....the bridge looks great as well as the groundwork. inspitation for the future..and probably much cheaper and more satisfying than buying a ready made one.

Alguhan, truly impressive - the 'mould' idea is a really good and simple one... Some really solid ideas here, thaks for shaing it!..Jim

A very nice, simple step by step with photos.....
Thanks for sharing and showing us it.

Nice job - straight forward and simple.

Simple? LOL I wish I could do the same thing haha. I'm not very good in this sort of things.

Looks really cool! Great job!

Thanks for sharing Alguhan

Must try this too one day

Alguhan, very nice idea! I have been wanting to build a stone bridge for sometime. You have just simplified it for me. Thanks for sharing!!!! Kevin

You make it look easy, interesting, and even fun, with an excellent result. Thanks for sharing!

Wow, very cool, what an idea! Great job, I like, I like! (and everything else in the scene looks great too!)

Good idea Alguhan, simple and efective I like also the nature around the river.

Outstanding and way cool! What did you use to keep the plaster from sticking to the cardboard box you used as a mold?

Great, plasterwork looks more real than the resins, what kind of paints did you use? I guess you started with a grey ground and finished with white shades. I would suggest some more weathering.

Great step-by-step Alguhan. You make it look so simple!

Great job. Thanks for sharing your technique.

Very simple and beautiful. I like the technique. I already bookmarked it.

What are the dimensions of the stones...or how wide should they be?

I'm going to use your technique on a vignette I've been planning...a Panther stopping on a bridge while the crewmen are pointing up (I think the crewmen are from Dragon).

Thanks for the informative and excellent SBS Wampum. It'll definitely be a great guide to anyone wanting to do a stone bridge.

Hi friends,
Thanks a lot for your comments Here come the answers to your questions:

Actually the cardboard ý used, had a shiny coat which didn't adhere very much to the plaster. I throw it away when the plaster was set and still wet.

First of all I used a cheap acrilic wall paint, dark grey colored. The plaster sucks every kind of paint at this first step. Then I drybrushed with oils. It will be weathered with enamels and pastel chalks.

Depends on your reference picture Angela. I didn't measure mine. I'm working with plaster for a long time and I think my hands automeasures every thing at 1/35 when making this kind of objects from plaster It will be enough to compare yor stones dimensions with your figures or vehicles.

cheers

Thank you.

By the way, I forgot to ask you one thing. What kind of plaster did you use? In my experience, plaster of Paris dries too quickly.

Thank you.

No problem Angela
This plaster is bought from a hardware magazine. It is greyish white and I think it is what you call plaster of paris.

hi brother,
Great step by step article especially for the plaster of paris lovers like me. thanks for posting it to general forums too.

Alguhan, I am seriously impresses by this. I tried myself some time ago to make a bridge for a dio from scratch, and in the end I dumped it. I might try again now after seeing yours, it looks really good. Thanks for sharing!

Wow, impressed with your idea's simplicity. Thanks for showing us.
