We got the final go-ahead on today's job late yesterday. We got a call to make 4 wishbones for a shoot on Thursday, but they needed them by 5 pm today. Pretty tight deadline for sure! The saving grace was that we had made wishbones about 4 years ago, and still had the silicone mold for them. The original piece was made from a sculpted piece of 1/4" sintra and epoxy putty.
In order to make the rubber mold as easy as possible, the original was made curved in one direction only, while laying flat on it's back. If you de-mold the part a hair early, you can bend and twist it to a new shape, and it will harden in that new position
I also put a hairline stress crack in each of them to insure they would all break the same way every time. I'm sure this will be a quick and dirty shot, but it's good to know that our stuff won't be giving them any issues.
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.
