I ordered some mold making supplies from: http://www.smooth-on.com/ . I then cut out the flat parts of the pillar and trimmed them up so they would interlock. I made a small box and contact cemented the pcs to the bottom face up. I mixed up the mold making liquid and poured it in. After it set for a day (today) I pulled out the new mold, removed the masters, flipped the mold face up in the box to maintain the shape and poured in some Hydrocal Plaster .Here are the results.
I'll be using these all over my layout. It was a fast and useful project that I hope you can use too!
