Leg Rehab, Day 6

One final day (I hope) of finishing the legs before trying to paint again. Just a little light touch-up and sanding on the legs, and I think they are good to go. I'm keeping my fingers crossed.

Leg Rehab, Day 5

More of the same (I realize this is getting boring, it's no party here either).

I cleaned up a bit of the work I did yesterday. I hit the white leg's ankle slot with a spot of primer to get an idea of how it was turning out.



Then I continued sanding, Bondo, lather, rinse, repeat. One more day of this (I hope).

Leg Rehab, Day 4

I did some more work on the legs this evening. I sanded the top edge of the right (painted) shoulder, in an effort to get it smoother. I also sanded down the Bondo from yesterday's under shoulder detail pocket repair.

Later, I finished placing the paper plate cutouts and Bondo into the final pocket slot (it looks just like yesterday's entry). I'll sand that down tomorrow.

I also applied Bondo to the ankle slot on the right leg. I'll sand that down tomorrow too. I may need to make one more pass with the Bondo, we'll see how it looks first.



I'm trying to finish up the repairs by Friday night, so I can go back to Mike's for final painting Saturday.

Leg Rehab, Day 3

Work on fixing up the legs continues. I sanded the mess on the white leg. I also concentrated on making the curve at the top of the leg as even as possible, using a block of wood with sand paper wrapped around it. I originally used a hard rubber sanding block, but I think that had a tendency to round the corners. Lesson learned.

The paint scheme reminds me of a Holstein cow. That would be an interesting R2 pattern. Moo.



I also applied some more paper plate cutouts and Bondo to the under shoulder detail area. Of course, I'll sand this down tomorrow. One more to do.



I finished up by filling in a small thin line on each of the ankle cylinder holders with Bondo.

Leg Rehab Day 2, Sanded Cylinder Holders

More work on the legs, and this will probably continue throughout the week.

There is a slight curve along the edges of the legs, so I used some sandpaper wrapped around a flat piece of scrap wood to sand the edges flat. I'm not done yet, but I made decent progress. I also worked on another pocket for the under shoulder details. I used Bondo again to affix paper plate cutouts to the top and bottom edges, and filled gaps with Bondo. I'll sand the mess down soon.



Speaking of sanding, I sanded the primer on the ankle cylinder holders. They are pretty smooth, but I need to fill in a thin line that I accidentally made when I was sanding against the pipe in the vise.

Leg Rehabilitation Begins at Mike's

"You can repair him, can't you? You must repair him!"

I've danced around some problems with the legs for a long time, and it was time to face my demons.

First off, the armpits for the under shoulder details are hideous on my legs. So hideous that I rarely post pictures of them. Second, I did a poor job in implementing Alan's well suggested and well explained styrene channel for the slots in the ankles. So, in all embarrassment for my inability to execute, here's the ugly truth.




Mike Senna kindly offered to help me do some repairs. Starting with sandpaper and Bondo, we started smoothing and filling gaps in the armpits and slots. Keep in mind that I've never purchased Bondo before today, let alone used it. I've heard of it ("that car's body is over half Bondo"), but that's about it. Bondo is my new friend now.



We used paper plates (you read correctly) cut to the proper size and shape to smooth out the edging on the armpits and legs, with Bondo between the paper plate snippets and the wood. Paper is wood, right? It can be glued, primed, painted, etc.



When we were done, the areas we worked on looked much, much better.




Sure, there's a little work left to be done, but this was a big boost.

I also still need to sand down the leg I painted white last weekend, I'll work on that during the week. Hopefully next weekend the legs will be ready for another try at a final painting. Stay tuned...

Started Ankle Brackets

I started working on the ankle brackets today.

I'm making these out of PVC, once again following Mike's example. I'm also going to deviate slightly from the blueprints. Where the blueprints have the booster covers sitting completely on top of the ankle bracket, I am going to have them go through the ankle bracket, by cutting a hole in the bracket where the booster will fit.

I started off by cutting a 12"x24"x1/8" sheet of gray PVC roughly to size. First I cut the length, then the width.



Next, I traced the outline of the bracket shape onto the PVC, using a pin and an aluminum bracket that I'm not going to end up using on this droid.



After that, I rough-cut the curve using the Dremel cut-off wheel attachment. This was like a knife through butter, but don't breath the fumes!



I cleaned up the curve with the Dremel drum sander attachment.



I also spent a little more time working on the cylinder holders (more primer) and tried sanding the unpainted coin slots to get them to fit through my skins. They still don't fit, I may have to try cutting the one row of six slots into two pairs of three. Or even just cut them each out individually. We'll see.

Started Cylinder Holder Primer

I started spraying primer on the ankle cylinder holders. I did not use wood filler on these first, and I may end up regretting that. I sanded the primer in the evening, and will apply some more tomorrow. If that does not hide the grain sufficiently, I may have to sand down to the wood and apply putty.



Hmm, I need to start taking better care of my yard.

Unmasked Ankle Cylinders, Prepped Cylinder Holders for Painting

Yeehaw, I painted something right on the first try! The ankle cylinders appear to have turned out okay.



I also prepped the ankle cylinder holders for primer/painting by drilling a hole on the holder side, so they can sit upside-down on top of the same rods that the cylinders were mounted on. Hopefully I'll start the process tomorrow.

Finished Painting Ankle Cylinders, More Cylinder Holder Sanding

This afternoon I applied the blue paint to the middle section of the ankle cylinders. It was the usual process -- mask off everything but the middle section, then apply purple, blue and clearcoat. I was able to do all four cylinders. Hopefully when the tape comes off it will all look correct.



I also put in a little more time sanding the ankle cylinder holders, they should be just about done.

The PVC sheets I ordered yesterday from McMaster-Carr for the ankle bracelets arrived today too. I ordered two 12"x24"x1/8" sheets.

Sanded Ankle Cylinders Holders

The fun never stops here.

All I did tonight was work on the curve at the top of the holders that the ankle cylinders sit in. I wrapped some 60 grit sandpaper around some spare 1" pipe that connects the legs together, and sanded for a while. Care must be taken during sanding, or else a warped curve results.



I'm not sure if I'm done yet. The holder hangs over the edges of the leg by a small amount (less than 1/8" on each side). Depending on how lazy I am, I may or may not sand these down some more.

I'm glad these are optional on the middle leg.

Touched-Up Booster Cover, Ankle Detail Blue Paint

After consulting with Mike Senna, I'm going to hold off on painting the left leg, and Mike and I will get together next weekend to try to get the paint on the legs right.

All I got done today was some touch-up work on the blue paint on one of the booster covers, and ankle details. I used the pie tin again as a palette, first applying primer, then purple, then blue. The areas touched up were so small I didn't feel the need for clearcoat.

Tried Painting Right Leg, Received Front Logics, Painted Middle Ankle Cylinders

More misadventures in painting.

It would seem simple enough, just point spray can at leg and spray, right?



So, how did I manage to do this?



I seem to be self-cursed when it comes to painting. I may or may not try painting the left leg tomorrow. What's the point if it's just going to end up like the right one? In the meantime, I guess I'm going to have to sand that mess down. Maybe I should go into the texture coating business.

On the good side, my pre-assembled front logic displays from Ben and Jason arrived today, and they work great.



I also painted in the middle leg's ankle cylinders silver today.

Started Painting Ankle Cylinders, Fitted Dome Bump Switches

This evening I painted the outer legs' ankle cylinders.



I also sanded the threads on the dome bump switches to fit inside the corresponding holes in the dome. I am strongly leaning toward painting these blue later.

Ankle Cylinder Primer, Prepped Legs for Painting

Nothing too exciting today.

After taking the day off from building yesterday, I applied primer to the resin ankle cylinders this evening.



I also tried using rubbing compound on one my resin ankle details, where some silver paint ran into the blue, with mixed results. I may repaint that piece.

Finally, in preparation for hopefully painting the legs this weekend, I applied some final touches of wood putty to them.

Painted Under Shoulder Details, Ankle Details, Worked on Dome Bumps

Today I painted the resin under shoulder details and the rest of the ankle details silver/chrome. Unfortunately, even though I masked the already-painted blue area of the ankle details, somehow a bit of silver paint leaked onto the blue. I may try rubbing compound to see if I can get the silver out, before I resort to repainting (again).



I also purchased a pair of rocker switches from Radio Shack, that will double as dome bumps and on/off switches for the dome electronics. These switches have a square bezel, so I spent time filing them into a circle. I may paint them blue, I haven't decided yet.

Under Shoulder Detail Primer

Not much building activity to report today. The R2 Builders Club hats that I ordered from Tom arrived, they look sharp. I applied some primer to the under shoulder details, and I plan to paint them silver tomorrow. I also removed the masking tape from the ankle details, and I may paint the rest of those silver tomorrow too, if I think the blue paint has dried enough on them to handle masking tape. I'm going to take a shot at making my own PSIs, so I went to Radio Shack and bought most of the components. Perhaps I can celebrate the Fourth of July by blowing up a board...

Repainted Booster Cover Tops

As is becoming somewhat of a tradition with me, I repainted yet another part. This time it was the booster cover tops. Hopefully this is the last time I'll have to do that for a while.

One Year of Building

Today marks my one year anniversary of my first building activity.

I suppose I'm just about where I would expect to be. I figured it would take between one and two years to complete this droid, targeting completion at one and-a-half years (i.e. end of this year).

The number of mistakes I've made is too numerous to count (similar to the dollars spent), but I have to say I have learned a lot along the way. I keep a "lessons learned" document in case I am crazy enough to ever try this again.

Once again, I have to thank folks like Mike Senna, Alan Wolfson, Calvin Thomas and pixelFiend for helping to get me this far along, without their help and encouragement, no droid for Victor. And thanks to my dad and Kelvin Miyake for letting me borrow a boatload of tools, and to Kelvin again for helping with some of the more challenging cuts for me. And let's not forget the R2 Builders Group in general!

Okay, enough with the acceptance speech. I ain't done yet by a long shot. Back to building!

Stripped Paint and Reprimed Booster Cover Tops, Painted Ankle Details & Wedges Blue, Touched Up Horseshoes

The first thing I did today was make a run to Ace Hardware in Corona, to pick up six more cans of Rustoleum Deep Purple Metallic. That should last me a good long while. It was 101 degrees Fahrenheit when I arrived there in the morning.

Later in the day, I stripped the paint off the booster cover tops, since I messed them up yesterday. I just used acetone-soaked paper towels to scrub off the paint.



The original primer was left mostly intact, but I later recoated a couple of times, and will sand and reprime again tomorrow.

Next, I painted the blue portions of the ankle details, and the cylinder wedges.



Finally, I touched up the holes where the buttons and hydraulics live in the horseshoes. I didn't get complete coverage with the spray paint, so I sprayed some of the same paint into a pie tin, and used a small paint brush to touch up those areas.
