When I lent my services to a collegue who was working on a film about 12 years ago, I was introduced to the world of cnc. I remember watching this huge machining centre milling out a slab of mdf and turning it into a fantastic set of gears. I knew that it would have taken me hours to achieve the same thing with traditional power tools. I decided then that I would invest in a cnc router for my own business Oxenham Design. At that time I could turn on a computer, but even to check email seemed like a crazy set of operations. I persevered and learned every piece of relevant software I could get my hands on. I am now fortunate enough to be using Vectric's ASPIRE software, and Techno cnc routers, which has helped us to create some amazing projects, both in part, or in full. I thought that this blog would be a great place to share "behind the scenes" adventures with the software, materials and equipment we use, as well as the projects we build.

My Friends Nut!

The last step in the modelling process was to use a basic cylinder, and subtract it from the base peanut mesh. This cavity will get the half-round shelves glued in for displaying the product. Finally, I scaled it up to the 6 foot height requirement.
I exported the model out to STL Slicer to begin the final cuts for Larry's cnc.

The very top and bottom got sliced off. Larry wanted to cut this as 3 pieces. The mid section above would be a combination of rotary CNC and hotwire,

 while the top and bottom would get single sided machined with a 1 inch ballnose cutter.
Here's Larry's cnc chewing out the giant peanut! Keep in mind, that's a 1 inch ballnose cutter in the collet. Pretty big peanut!


I think it came out great! Good job Larry! I might have to hire that guy.........maybe! :)
I think he was going to send some pictures when his client had finished the painting. If he does, I'll update the post!

I Like Big Nuts and I Cannot Lie, You Other Brothers Can't Deny......

A big part of our work is just at the computer end of things. Either 2d graphics, 3d modelling, and sometimes product and set rendering.
The last job was for a friend and college of mine. Larry Ryan is a guy I met a few years ago on a job, and we seem to have just hit it off! His company does mostly extra large styrofoam stuff. If I need a 2 part hardcoat sprayed, or the project is too big for our equipment, Larry is who I call. He actually cut our oversized Cadbury egg last year because of our time constraints!

Due to his time constraints this time, and overflow of work, he asked if I could model a 3-dimensional peanut, that would eventually become a set of display shelves for some kind of promotion. All I have to do is model, and slice it, then upload the files. He'll cut it on his oversized 4 axis cnc router and hotwire cutter.

 The order of the day was to get the base shape of the peanut modeled. This was done in Hexagon as a simple sub-d surface. I pondered how to build this as all a single mesh model, but in the end decided to make it as 2 separate meshes. And as a cnc router doesn't care if a mesh is watertight, it made modeling this way a little easier!
Once the base shape had been created, I used a few online reference images to tackle the raised texture portions of the shell. I decided to model this a little more stylized than a real peanut. There will certainly be no mistaking exactly what it is from a distance!
I rendered out the two meshes, and sent the drawing for approval. Everyone seemed quite happy with it, so the next step was to prep the model for fabrication.

Nuit Blanche..........The Environmental Aftermath.......

The crew call time for the removal of the Nuit-Blanche display was 7 am Sunday.
 WHAT?!?!
You heard me!

This meant setting the alarm for 4 am. Not exactly my idea of Sunday morning, but it's all part of the gig. This is what the scene looked like when we arrived. All the water in the fountain was a horrible colour of dark muddy brown, kinda gross. This meant that it went perfectly according to plan! There was scoady brown foam floating on top, and the fountains were running with the goop no coming out of them! It was perfect! I wish we had gotten to see the whole event unfold, but we just couldn't be there for the show.

 I snapped this picture as the sun was coming up, after we had the riser cladding removed. The planned graffiti on the tanks was certainly a work art in it's own right!

This was a great project to be involved with! Jody and I had a great time, the whole way through! We met some really great people from the FX team, as well as the City!

A special thanks to Trevor Highland at the City of Toronto for getting us involved!
