It is hard to believe that it was almost ten 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 of these machines - but I just knew it could do fantastic stuff.

Along with the CNC router I discovered the wonderful material called Precision Board and the glues, primers and other companion products they offer. Since then we have gone through many tons of the material using it in most signs and projects we tackle. This journal will chronicle our many adventures both past, present and future. I'll talk from the perspective of someone who pushes these products to the creative limit on a daily basis. I'll be adding to the stories two or three times each week. -dan

Runaway Mine Train sign part 3

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.
