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 with what I saw 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 and LOTS of hands-on practice I quickly found out that my MultiCam router was capable of just about anything imaginable.This journal will chronicle that journey to date and continue each week with two or three entries as I continue to explore just what is possible with this wonderful tool... -dan

Gnome pub sign step by step - part 3

Each time we create a hanging sign we think of a number of things. The first is that we want to create a bracket that fits perfectly with the sign design, and not merely an afterthought. Our second thoughts are about strength. Precision Board, even the heavy 30 lb density has little structural strength. We have to design that in from the start. The fact that this hanging sign is to go into a pub means we have to design in a little more in case some tough guy who's had a few too many decides to do a chin-up. 

It starts with the internal frame inside the sign. We opted for 1.5 inch square tubing in this case - plenty strong for the task. I laid out a vector which is 1.6" wide - which allows a little extra wiggle room. These rectangles were combined and formed the cut path for the internal welded steel frame. The brackets will weld to this frame.


I then laid out the 3/8" thick angle brackets we would fabricate for three corners of the sign. The fancy bracket was then drawn around these mounting points using EnRoute drawing tools.


I then duplicated and flipped these vectors for the bottom portion of the bracket.



The wall mounting flange was built using a variety of arranged shapes which I then combined. Adding the bolting holes finished this piece off.






To create the welded 3/8" plate angle brackets I created a 4x5" reciting;e and then added an oval. This would cut out leaving room for the 5/8" round rod that would go through them.


I also rounded the outside corners using the chamfer drawing tool.


The files were then ready to send to the plasma cutter.  I'll cut these while the router whittles out the sign faces. I can hardly wait to assemble this little beauty and see how it all looks together. Stay tuned...
