41:33 - Scenery modeling - more rock cut techniques (2012)

Expert modeler Mike Confalone demos more techniques for modeling terrain with rock cuts. Mike starts with cleaning up the base area by adding ground cover, then moves on to adding rock rip-rap and modeling evidence of blasting in a rock cut. Includes 3 video segments in all.

For the previous video segments on casting rocks done to prepare for these steps, see Casting, blending, and coloring rocks

Part of the Scenery Modeling Outside the Box DVD, volume 2.

•Doing a ground cover base (17:09)

•Adding rip-rap to a rock cut area (9:54)

•Modeling evidence of blasting in a rock cut (14:30)

This HIGH DEFINITION version of our STD-DEF DVD content is available free to TMTV members (HD version costs extra to purchase and is only available as a download).

All the Allagash quarry project segments in this series include:


Mike's also put his entire Allagash layout story in writing in his comprehensive 4-volume eBook series containing over 400 pages and hundreds of photos illustrating his points. Learn more about the Allagash Story eBook here.


Picked up that you use Rit dye and alcohol for your washes. What differences would you get if you used India Ink or black acrylic paint and alcohol for your washes?

India ink is generally only one color - black. Rit dye is available in many colors, and since it's a fabric dye it's colorfast (designed to not fade over time and there's more quality control over color from the factory), plus it thins well with alcohol. Cheap acrylic paint may not be colorfast, nor are color batches guaranteed to be consistent from the factory (same color of paint bought at different times may vary slightly in color). Also, many acrylic polymers react with alcohol and gel up, forming globs in your wash.

A better thinnner if you want to use acrylics is Armor All auto glass cleaner. It is clear (not blue like a lot of window cleaners) and it breaks the surface tension to flow very well like alcohol, but doesn't react with most water-based acrylic polymers.

I was glad to see you added a small but relevent detail in the "blasting evidence" video segment.  I had written a comment somewhere about possibly modeling the vertical grooves in a blasted rock face, something I had observed in northern NJ along the interstates, but mostly absent in the modeling of a similar site. The grooves indicate where the rock was drilled into, and the blasting charge(s) set. Not a big deal, but it's a neat touch of realism if it's there. As always, Mike, great videos and superb modeling - a joy to watch, and learn from!

Top job on colouring the blasted rock face .The colour really jumps out . All quarrys usually work on a bench system . I myself would have left the top bench as it was .As all the machinery drill from the top of the bench  to the depth of the working level .     Smokey   Dawson       Australia
