The Build I Started in 1977

The movie Star Wars hit me with impact! It knocked me over! I've always loved Sci-Fi, but in this movie everything was perfect! I identified with Luke and his struggle, the story pulled me in, and the description of The Force was almost spot-on to what I value as religion. I've now seen episode IV literally, without exaggeration, thousands of times. (I had a bootlegged VHS tape and spent a couple of years one winter snowed in at Lake Tahoe.)

Early 1977 I got a book with a blueprint of R2 and thought, "Wow! I'll bet I could build one of these things!" R2 was my absolute favorite when it came to robots. But the prints had no dimensions!

Then, August 3, 1977, I heard that R2, 3PO and Darth Vader were going to be immortalized with their footprints in cement down at Grauman's Chinese Theater. Shortly after that I was down there with my calipers measuring the prints R2 left so I could scale the blueprints I had.

Remarkably, the measurements of an 18" diameter dome and body are incredibly close to what the R2 builders of today have standardized as proper measurements. With the new prints and measurements at my disposal it was easy to mark and roll a sheet of aluminum into an R2 unit's body with the help of a like-minded superintendent named Sherman Prosser.

I then found a trash can with the correct dimensions and made two half molds from the top, spliced them together, and did a polyester resin and fiberglass matt layup of the dome inside the mold.

I reinforced the edge of the dome with aircraft grade flexible foam and fiberglass.

Next I made a vacuum form mold and formed 3 plastic leg pieces with the help of a good friend "Hippie" Greg LeBlanc who ran the vacuum form machine.

I knew had to beef up the leg inside structure so I fabricated a frame but the first frame I fabbed was too flimsy.

I fabbed another frame and bonded the thicker aluminum plate to the back of the plastic choosing to reinforce the points that appeared would have the most stress.

The cutout in the back, as I look at it now, isn't to print OR any of the pictures I can find. I have no idea WHAT I was thinking! (After all, it was like over 30 freaking years ago!) Also at that time the interior of R2 was a mystery.

The little details like a piece from a heat gun vent, nozzles from airline interiors, toy racetrack for commutator strips to get electricity from body to dome without twisting wires together when the dome rotates -- I had a lot of little parts I had fabricated that have gotten lost throughout the years. Here are a few of what's left:

I was doing R&D on silicone air bladders to inflate inside the layup of a carbon composite ejection seat frame, so I could vacuum bag and oven cure the part. I quickly would use the excess silicone and spray it over a quick mold I made instead of throwing it out, and made a silicone mud-purge bladder shown after R2 gets spit out of the swamp on Dagoba.

I cut and fit the only access door, the only blue piece, on my dome so far for this.

The shoulder stand-off pieces (what I was calling them) were really easy! I built an 18" diameter curve into the bottom of a cylinder and filled it solid with high temp tooling resin and glass, then when cured ground where the legs join flat.

My shoulder horseshoes, I see from the better pictures available today, aren't the correct dimensions. Not sure what I was thinking because I see they aren't to print either. There are differences in the print and pictures I have too. The shoulder horseshoes are made from white tooling resin and fiberglass. The slots for the buttons and bar were pieces of wax I laid up around and dug our after cure.

I was beginning to become overwhelmed by all the doors, gadgets, and abilities that R2 had as each movie came out. Then, somewhere around 1988, I got laid off from the aerospace plant where I was working and R2 went into storage. I lugged the little droid - or rather the pieces of droid - around with me whenever I moved until present day.

Move ahead to 2011 - I met a girl named Leya Falcon who is a huge fan of Star Wars. (More about Leya below.) It got me thinking, and I dug down deep in the wreckage of my past and pulled out a bunch of dusty old parts and the ancient blueprints I used to fabricate them.

After careful consideration I've decided to put together what parts I have as a mock up for photographic purposes. (Leya wants to shoot with R2 and I need to have a visually viable prop.) Then, one piece at a time I can replace the mock-up parts with working pieces until I can complete my droid. I've begun researching the work done on standardizing measurements, improving materials, the stats for R2D2, and the rest of the work done by builders since the late 80s until now, and I'm impressed at what I see from those who have been building droids since Al Gore invented the Internet.

The overwhelming task (for me) of the electronics will be a lot easier with the assistance of the craftsmen in the R2 Builders Club and the R2 Builders Yahoo Group. Find the Yahoo group here:

As the economy gets better and I have more income I can spare for my old hobby, I look forward to getting back to the build I started nearly three decades ago. May the force be with me!

Leya Falcon
  • Leya Falcon is a brand new columnist at Adult Industry News (AINews.com), writing her first column for us soon after her very first scene.
  • Leya was referred to us by Bill "Papa Bear" Margold, who's advice sought to help her brand her name.
  • Leya's column is called "Falcon's Flight". She's been writing for us since December, 2011.
  • Read Leya's account of her experiences starting out as adult talent, behind the scenes stories, and sexual adventures. She is absolutely crazy. She is also an enormous fan of Star Wars.

CONTOUR SANDING

When you sand, use a flexible sanding block or spline board to keep the contour. Sand in a 45 degree alternate pattern. Hard to explain. I should learn how to make a YouTube video on this.

I use a bending spline board - a piece of flexible plastic about a foot by 3" and put fine sandpaper in the middle, and a paper shim the thickness of the sandpaper on the outside for the up-down contour. I would alternate up-down strokes at 45 degree angles. The side to side sanding I would use a full sheet of paper, strokes side to side alternating at 45 degrees. I'd also use a finer grit sandpaper than one would expect. If this is unclear, let me know. Also, if you glue little blocks of wood to the ends of the spline board they will act as handles. Bending a full sheet up is it's own handles.

For small pinholes use glazing. You can also "water down" Bondo with a few drops of liquid styrene. It sometimes pools in a gallon can of Bondo. I've also used a few drops of acetone to thin it down and can paint it on with an acid brush.

Composites was my specialty when I worked in aerospace. Oh, and put too little on rather than too much. You can build it up easier than sand it off. Practice on some scrap first if you've never done contour sanding.

It might be a good idea to invest in a cheap respirator. Harbor Freight or a paint store should have a good one. I'd also ask the sales rep if it filters out whatever fumes the materials you are using puts off if I can't find it listed on the box. I used to get bad headaches when my respirator wasn't seated properly and may be partly to blame on my poor memory!

Bonding Epoxy to Polyesther

Epoxy and polyester do not cross-link. HOWEVER, there is a trick to bonding a poly/epoxy lay-up by laying-up the glass and epoxy into the poly lay-up before the poly is completely cured. It must be gelled and still tacky. Though I became good at it, there's still a high probability of de-laminations.

Releasing Tooling

Also, use a good mold release; first buff out your mold with car wax, then apply a coat of Partall green wax and buff it out, then a spray coating of PVA (poly vinyl alcohol). I've even gently waxed a coat of PVA to get as many sheer planes as possible for complex molds.
