Diorama Dilemma - Opinions Requested

[PHPaul]

In order to facilitate getting it out of my basement if and when that becomes necessary, my diorama is built in two 2x4 foot sections.

I didn't plan ahead for growth and now I want/need to pour a stream right at the joint between the two sections, but still be able to separate them.

My initial thought is  to line the front (finished) half of the stream with Saran wrap, use a little silicone to seal the bottom gap, clamp the two sections together, build dams where needed and pour that way.  My thinking is that the Saran wrap will allow the epoxy to conform to the shape of the bank on the finished side and still allow it to release so I can separate the halves.

Think that will work?

Better ideas?

I don't think I've ever seen a farm with a stream anywhere near the buildings. Sometimes a pond, but if a stream were connected it could be off in a direction away from the section where the buildings are concentrated.

1.  There's a county drain that runs within 10 feet of the NW corner of my house, so it's not unprecedented.

2.  As far as the pour goes, the Saran wrap and dams worked fine.  I'll need to give it 24 hours before I try separating the halves, epoxy cures REALLY slow in a 60° basement.

Houston, we have separation!  

Worked perfectly, just needed to trim a little "flash" where capillary action pulled the epoxy up some folds in the Saran wrap.  A little clear gloss where I sanded some sharp edges and we're good.

Nicely done, Paul...... your carefully thought out plan has paid dividends!
