It's been a busy couple of weeks. I've been all over the place with this build. I finished up a center foot and began the dreaded main feet. I actually am building them second time. There's a trick to getting the motors and wheels working in the foot frame. I also worked on ways to secure many of the electronics, the battery, and various greeblies in the body. And I painted out all the blue pieces. There's an amazing number of small persnickety jobs that can eat up your time. I'm pressing on though. Here's a random smattering of photos. I know, not a great build log but it shows some milestones. More soon.
I do have a build log there, but it's not much more detailed than this post. Honestly, I don't feel like I have much to contribute that dozens of other guys have not already. I'm sure I'm doing a few things differently. I am sharing some key milestones though.
The plastic was from a local supplier. But you can order it from Tap Plastic. The motors are from the e100 razor scooters. They are frequently on eBay.
Okay, massive photo update ... I've been busy and have now essentially completed the build portion of Artoo. I've also done final paint and assembly on the legs and feet. All motors and wiring installed. Today I did final paint and assembly on the dome. No electronics yet ... but Artoo has his head
One thing I wanted to share is my experience with silver paint. I bought many brands to find the ones I wanted to use.
I ended up using essentially two for my silver parts:
• Krylon MXX Silver Metallic (I only found this at Wal-mart)
• Rustoleum Silver Bright Coat Metallic Finish
The Rustoleum is a typical SHINEY chrome finish. It;s best when it's applied thick and left to dry for many days, if not weeks. It's temperamental and fingerprints easily. I'm using it for some key resin pieces I want to look like polished "machined" aluminum – Like the detail parts on the legs and shoulders.
The Krylon is a nice satin aluminum finish that dries fast and doesn't rub off. I'm using that in most places on my droid where I want silver. It's much less shine, but is super durable.
I like to combine these two in interesting ways. My one-piece resin holoprojectors are the satin aluminum with the chrome in the inner surface to add some depth.
For my dome I tried several tests of products on test sheets before committing to using the Krylov Maxx. I use Rub N Buff on other props, but I just didn't dig how it was looking here. The Krylov went on super smooth, then I stuck the dome on the Rockler and used a Scotchbrite pad to spin some lines in it. I'm really happy with the results.
This morning I glued the blue panels onto the dome with E6000.
Okay ... almost 6 months to the day I started R2 is built. Well, the structural build. This is the first time he's been completely together on on his wheels. I do have all his electronics installed ... just not wired. I'll get some pics on the inside tomorrow.
