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

Building the tank turret

The next part of the tank we are building is the main turret.  It is pretty simple but it uses tools in ways not often done. The turret is built in two pieces - an upper and a lower half.

The first step is the create a relief using the bevel tool, but we'll do it with a twist. That is to use the limit to height tool which effectively flattens the top with a nice bevel around the edge.

The gun barrel mounts to the front of the turret and so we needed to build a box on the front. This is done as a separate relief. I made this 0.8" tall - just like each half of the turret.

The gun mount relief were then combined with the turret reliefs.

The two halves of the turret then got a round modification by using the ADD TO RELIEF command using the two circles as masks. These reliefs were created separately and then merged highest with their respective halves of the turret. The large circle is the top portion. We'll build a hatch onto it shortly.

That's all I can fit on this post but next time we'll build the final bits to get this ready for routing.
