Deep Water on a Round Base

[CreganTur]

Searching around hasn't yielded any results, so I'm asking for a bit of help.

I'm working on an ambitious project that involves a large diorama on a round wooden base. I'm going to be adding water effects to create a river that's going to be 1-2" deep (depth is controlled/determined by how high different areas of the river bed are).

I know I've seen a tutorial where someone did a water base on a round socket, but I cannot find it anywhere. By biggest concerns are:
1) making the mold around the base water tight and strong enough to hold in the product
2) looking for products that work in a single deep pour- someone used a product that wasn't a typical clear resin and they were able to do a very deep base in a single pour.

Anyone have links to resources like this?

Most "water effect" pourable plastics are quite a bit thicker then water,.. so I would say that you won't have to worry about much it running where you don't want. All you'll need to do is build your form in whatever shape you want it to be, mash a bit of putty around the lower outside edge (just in case - be sure the seam is sealed), then pour and let settle. Also, a good time to add any coloring to the water if you want it blue-ish or murky brown or whatever,.. before you pour. Woodland scenics makes some water efeect stuff. I'd probably start there first.

Do you have a picture of the size/shape of the area to be poured? It might help to determine a final solution for your problem.

I did one similar. It's not so hard.

use this:

And really I just used the masking tape on the sides approach from here:

Hope that helps give you some direction. Also TEST A FEW TIMES BEFORE RUINING YOUR PROJECT!!!!

Another tip that might be of note here is that 'clingfilm' is designed to only stick to itself as such this function is pretty useful for lining any mould used for water effects with a view to the removal (obviously this only really applies to large undetailed areas but for example coating the inside of a cardboard tube lined with clingfilm then filled with resin once hard simply cut cardboard and peel off film = job done)
