DM,
LMAO!!!
I finally shot the mold and two castings. The first was with just hydrocal. The second was tinted with Woodland Scenics Slate Gray. The gray is drying uneven which is perfect for the stone but, the tinting is showing ALL of the air bubbles. Even though I need to perfect my casting technique, I am quite proud of how this turned out. I've been chipping at the air bubbles with a pick to represent damage to the stones by the heavy tracked traffic over them. Creation by mistake usually works out rather nicely.

The AVRE to give some scale to the size of the casting.

Thank you for your patience with this build. Now with the road section casted, the base can now resume progress.
Cheers
Dave
