WELCOME!

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

Assemblymen;ling the Copper Crown Sign


We formed the pieces for the crown using our roller and also by hand as necessary.



Then everything was welded up into once assembly.




While we could have routed the end pieces it was easier and faster the do it by hand. We formed some pencil rod in the shape we wanted and then attached some metal lath. 





The ring around the crown was cut from a piece of 16" diameter pipe. The Curved flat bar was hand shaped and formed in pieces. It was then welded together to form one bracket that perfectly matched the shape of the scroll. We then hand sculpted the curls using sculpting epoxy. The plasma cut curlicues were then welded into place



A coat of sculpting epoxy was hand formed over thee plasma cut steel to formed a beveled form.




As with all of our work it got three base coats of colour and then blends and blazes to make it come alive.


Copper Crown - part one

 The second inn sign to go into production is the Copper Crown. To do this sign did we tried something new. The scroll would be routed, flipped and routed once more. We had a five inch thick piece of Precision Board which we'd been saving for something special.


We traced the vectors over the original concept drawing. To make the lettering curve to fit the scroll we used the transform tool called patch distort. The scroll was copied, flipped and then the lettering for the back of the scroll was done using the patch distort tool once again.




The fancy scroll work needed to be a little thinner so we could use sculpting epoxy to make it profiled. To do this we used the offset tool.



The bracket ended a mounting plate. We used some of the same elements of the scroll in it's design.


The cutting file for the crown was also designed in EnRoute. The upper pieces were copied and duplicated.


The scroll relief.was created using sweep two rails function. The vectors were curved in both dimensions. To start We made a zero height relief. The relief was then modified using the curved vectors and the sweep to rails command.







We only had once chance to route the file in a single piece as we only had one piece of 5" thick Precision Board. We marked out the spoil board and screwed some blocks onto it so we could flip the piece and then route the second side. The goal was to have everything line up perfectly. It did.


Once the routing was done We went over the scroll with the die grinder to add texture. We cleaned up the edges at the same time. From here on this sign was about assembly and hand finishing. I'll cover that in the next post.

North Star assembly

We tool pathed the North Star sign and then sent it off to the MultiCam. We routed it from 30 lb Precision Board.



There was still a little work to do in EnRoute. The piece below was cut from 0.1 steel plate. It would be the ring around the star and also act as structure between it and the front piece. To do this we needed to route a pocket for it.






Once we routed it this is how it went together.


Once we glued up the pieces we did a little hand work with the die grinder and added some small details with Sculpting Epoxy including the rivets and barnacles.






We then painted on three coats of paint before layering on further blends and glazes to bring the sign to life.

Building the vectors and reliefs for the North Star sign

The inn signs are now in full production and looking good. In the next series of emails I'll be taking you through the steps we took to create them. This will be a little different than most of my posts because Peter and I jointly worked on these files and he uses a slightly different path to production that I might. The thing with EnRoute is the the program is so powerful there are most often multiple ways to do a task. As we were designing and building with ourselves as a client we also changed things on the fly to make it better. We enjoyed even more freedom than we normally do plus all family members were weighing in along the way. It was even more collaborative than usual. We would show around the design and the person we showed it to would say 'That's cool but what would it look like if we did...'  As every member of our team is ver talented and has years of experienceThings changed a fair amount along the way.

The first version of the design hit the mark but it looked a little static. Someone suggested rotating the anchor and this necessitated a change to the scroll. Then the design was deemed production ready.


I imported the design into EnRoute and did a quick trace of thee main elements primarily to establish scale and proportions. I didn't have to be fussy as I was going to redraw everything anyways.



Using that original trace drawing as a guide I did a cleaner version.


Peter produced this version of the anchor vectors. The lower anchor portion was duplicated, mirrored and then combined.



At this point Peter designed the fancy little plasma cut bracket we would insert into the cut Precision Board pieces. It is one more level of detail that would help take this sign over the top when we were done.



The compass star is an element that needs a little explanation. If you make a star shape and then use the bevel tool to create a relief you get a funny shaped bevel. The higher the bevel the more pronounced this shape becomes. The image on the right is that shape. To get a true compass star the points are build individually and then combined. This is the method we used.


Because the star points are uneven in length lining them us is a little trick but as always there is an easy solution. The first step is too create a rectangle and then two lines through them.  Make sure the lines are longer than the longest point. These are centered using the alignment centering tool. I then duplicated the rectangle and adjusted  the length of the rectangles for each point. When I was done I again centered the lined in the rectangles.

I then selected the snap to intersection and drew out the compass points. When I was done I deleted the rectangles and grouped each star point with the intersecting lines.


I then rotated each point in 45 degree increments. 


Each segment was then ungrouped and the lines were deleted.


The ring around the compass star would be plasma cut from 1/8" steel plate. To build this vector I created a circle and then used the offset tool to create the inner circles. I then built double lines, duplicated and rotated them to form the segments. I then used the jigsaw tool to create the many rounded segments. Once I had all of the vector pieces formed I deleted the double lines and inner circles to leave the lines I needed. I then used the transform/distort/noise distortion tool to make the lines a little distorted. This will instant age to the cut pieces.



I then created a slightly larger offset of the compass rose and combined this with the segmented circle vector.


We opted to route the scroll in layers and then assemble them later with a little hand work to finish things off. It was a simple matter to build the pieces of the scroll using the draw tools in EnRoute. We then imported the lettering vectors. I used the transform/distort tool/warp tool to shape the letters to the scroll.


The vectors were now complete and we were ready to begin building the reliefs.



First up was the compass star. Peter used the bevel tool to create the star segments. He then combined them to form one relief. As an added level of detail he added a custom texture bitmap to the centres of each segment.


The banner was next up. The banner was built as flat reliefs which were then modified using various ovals. The lettering was subtracted from the base banner relief. It automatically followed the shape of the domed banner.





Peter opted to use the chamfer tool to modify the flat relief of the anchor bits. This created an interesting profile.





The triangle shaped ends of the anchor were created as a flat relief and then modified using the dome tool and a circle around them as a mask. The top ring was also created using the dome tool.



The top crossbar of the anchor was created as a mesh. This allowed us to build a complicated shape in one go. We used the revolve function.



The mesh was merged to a zero height relief.




This finished off the building of all of the files we needed for this sign. Next time I'll show the process of building and assembling everything. Stay tuned...
