While I am gathering my materials to post a tutorial thread as requested, I am once again posting photos of a project that have never been seen in their entirety before. This project came about four years ago with the intention of competing for the top prize at a local IPMS competition. We had already been commissioned to build a large scale B-52 that year, and we knew that if we wanted to bring this project to fruition, we would have to start building several months before the competition. R2D2 Astromech: Build time 4 months, over 1400 cans required to complete. Here we go. The first step was building the body from the plans we had enlarged at a local printer. The inner structure would be layers upon layers of can finally culminating with a white Pepsi which would be the final color. The body of the droid starts to take shape: After a few more weeks it starts to look like a R2 series Astromech instead of a domed garbage can: Next we start working on the two main legs. Again these are made with an initial outer structure folded into shape then reinforced with layer upon layer of can. Here you can see the layers of Coke being covered with layers of Pepsi: Now the finer details are added. We follow the highly accurate paper model pattern to a T and add in all of the parts enlarged to the 1:1 scale: Then at about 3 months in, R2 stands for the first time He isn't quite finished yet and there's still a long way to go: The dome needs a lot of work and the detailing work on the body begins Here we use specialized colored tapes purchased from an industrial supply store to create the details on R2's body: With the detailing complete, we start work on perhaps the most important detail, R2D2's dome: The inner structure of the dome is all can while the outer skin is aluminum foil tape. I opted for this since it showed better results than just painting over the can and it gave it the polished metal with a tad bit of a weathered look that I was going for. The colored areas are simply colored duct tapes purchased at a Hardware store: Finally, at 4 months in and over 1400 cans R2 stands in full 1:1 scale on the dining room table: We enter the local IPMS competition in the Miscellaneous other than plastic category and to my surprise and shock, soda can R2 took home the top prize of best of show, beating out some very tough competition that year. The final tally was 4 months build time and well over 1400 cans of all makes and sizes. R2 has Root Beer, Coke, Pepsi and Shasta Cola layers built into him. R2 on display at the show where he took top prize: After this build, I had no fingerprints for weeks due to the superglue residue, but that along with the multiple cuts, and glue incidents where worth it when kids and fans of all ages heard R2's built in Mp3 player with soundbites start chirping that familiar tone throughout the building. It was an honor to compete against paper, plastic and resin modelers and to also take home the Best Of show award in 2013!
