It is hard to believe that it was only seven years ago I witnessed a CNC router in action for the very first time. I was fascinated and simply had to have one! Although I had been in the creative end of the three dimensional sign business for most of my life I didn't really know what I would do with one - but I just knew it could do fantastic stuff.

Through extensive research I quickly found out that with the relative simplicity of EnRoute, CNC routers were capable of just about anything imaginable. This journal will chronicle that journey to date and continue each week with two or three entries as we continue to explore just what is possible with this wonderful software... -dan

Runaway Mine Train sign - Part three

Once I had the parts all routed it was a simple matter of gluing up the three layers with the welded steel framework encased inside. Two tubular arms stuck out the back for mounting to the building structure. I used the die grinder to even out the edges, purposely leaving a little texture of course. This same texture was done to the back of the sign as well. Bits of it will show through the timber frame building when it is mounted.

We then filled in the screw holes with Abracadabra Sculpting Epoxy. I used the same epoxy sculpt to the railway ties and beam and pressed in some wood grain. This epoxy is about one eighth of an inch thick. Then I added the join plate on the rails and the anchor plates and spikes to each tie.

I used my jig saw to cut some scrap block of Precision Board for the mine car frames. The wheels were them mounted to the frame using some quarter inch steel rods for axles. Some laminated blocks will form the armature for the cars and then it will be time for some more sculpting. Stay tuned for the next installment.
