Reply to "Continuing Saga …"

Spent almost two hours carving the first of many rock formations that will line the ravines using green insulation foam. I have to find a faster way to do this. I'm sure it will get faster as I go up the learning curve. I was thinking of making a mold and then casting them out of Hydrostone, but quickly realized that they each must be custom fitted to the contours of the ravines and that means carving each one separately. It got fast as I was progressing down the column since I scribed the overall contour on the outside and then use the Tippi hot foam cutter to chop away what didn't look like Kentucky Rock formations.

Ravine Carving 01Not having thick foam, I layered the pieces together using low temp hot melt. Here's some progressive pics showing how it shaped up. The picture of the rocks overhanging the Kentucky River is in the background and that's what I'm using as a guide.

 Four layers of foam to get a decent thickness.

 One down and a gazillon to go!

 

I'll glue them to the plaster with Loctite foam adhesive and then use Spackle to fill in any gaps. I think I'll primer paint them before gluing them to the substrate.
