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

Building the body

I've stated many times that we use 30 lb Precision Board exclusively in our shop. This is true when it pertains to CNC routing... but when we are hand sculpting high density urethane that will be coated with sculpting epoxy we sometimes use four pound foam. It is so soft I can practically carve it with my hands.

The rough armature for the robot body was a great place to use this less dense foam. It needed to be fit around the welded steel armature and then roughed into shape. I used there layers of 3" four pound foam. Since I was going to coat it in sculpting epoxy I wasn't concerned with gaps or rough edges. I used PB Bond fat set which cures in only one hour. I glued it up before I went to lunch and when I returned I was able to remove the clamps and get busy sculpting over the new form.



I used crumpled tinfoil to fill the gaps and holes and then pressed on a layer of sculpting epoxy. Once this had set I did another layer that was detailed. In a few hours I did the legs and the bulk of the front of the robot body. Rather than my usual rivets I opted to sculpt flat head screws for more of a retro feel. Tomorrow the bulk of the sculpt should be done. Stay tuned...
