Framed terrain carving of Mourne and Cooley Mountains, Ireland and Northern Ireland

Here is another terrain carving of my local mountains that I love to hike around on. I got 30m resolution this time, using TouchTerrain. I have documented the process in photos and a couple of videos of my Portable Primo MPCNC in action:

How long did the carving take, and what are the overall measurements?

I set up a 18x36 carve of the region in Wales were I was born and my dad grew up, covering a few hundred square miles. Carving time using a 1/8 rough and a 0.5mm ball but was estimating at 43 hours…

That is great! I really want to do something like that.

I love how the lamination adhesive highlights the contours, and that frame finish it off nicely. I also like how the epoxy flow gives the feel of waves and current moving around.

The roughing pass took 1:15, and 4:45 for the finishing pass. The carving is 423 x 290 mm, and 35mm thick at its thickest.

I put some comments and details in the Info window for each photo on Google Photos. Be sure to click on the i with a circle around it if you don’t see them

Thanks Kev, me too! It was a happy accident that the frame’s colour matches the plywood glue colour perfectly after I sprayed it with varnish.

The miniature Irish Sea has a mind of its own…you can see the flows and patterns revealed by mica changed a lot as the resin set. It was a chilly night in the garage, so it took hours to set.

I also like how both the sea and the birch ply terrain look totally different depending on which angle the light comes from.

Here is a short movie showing that:


The speed of your CNC is incredible. Or did you speed the video up? :slight_smile:

No video editing, those are actual speeds. Here is a summary of things I did to speed it up:


See the details now- thanks for adding that. It’s a ton of useful info.

Watching that 1/4” 3 flute go 75mm/s at 2mm DOC is something! Fastest I’ve pushed mine is 40 at 1.5 and figured it still had some oomph left.

Fantastic job, it turned out looking so real. Looks exactly like a satellite photo but better.

I have made a detailed tutorial on terrain carving for Instructables. See my post about that here.
