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

Wagon wheel sign glued

The wagon wheel sign pieces have gathered dust for almost a month as we were so busy with other things. Today the shop was quiet and I finally got the chance to do some assembling. First I had to create a file and cut the center layer to accommodate the steel frame. This frame would be welded up segments of 5/8" steel rod and a piece of horizontal 1.5" square tubing. The slots for the 5/8" tubing would be cut into the material. The square tubing slot was to be cut as part of the offset outline milling.

Here's the shot of the tool paths ready to be sent to the MultiCam.

Once I had cut the piece from 30 lb Precision Board it was ready to assemble with the rest. I cut and laid the steel into the slots and then tacked it in place using the actual wheel as a jig. The pieces were then removed and welded solid.

I then used PB Bond 240 glue, a one part adhesive made by Coastal Enterprises to fasten the components. I also used plenty of screws to clamp things together and keep them in line. These screws will stay in place.

The project had six layers in all which makes for a pretty beefy sign!

Once the glue has set up I'll start in on the hand work and then we'll sculpt the prairie dog that will be perched on top. Stay tuned for more progress...
