The AT-AT project -- THE AVERAGE JOE EDITION --

Beautiful! It's Starting to look Menacing!

DAY 5: Assembling the four legs and attaching the feet. (5 H)

Putting the top and bottom leg together is easy, but I suggest you get someone to hold the peices together while you drill the holes.

Attaching the foot is the hard part. Once I figured out that the drawings were not to scale, it all made sence. As I later noticed in the instructions "NOTE: These drawings are NOT to scale". Reading the instructions helps everyonce and a while.

Once the wish bone was attached to the foot, I had to make the ball joint mechanism for the left/right foot movement. I looked at the bible....the movie, and noticed it differed from what was in the instructions. I realized all I had to do was invert all the supplied peices (ball joint males and females) to acheive the look I wanted. The brass tubes slide into one another. It's quite a nice movement.

All that was missing was something to hold the leg and the foot together. That Something, was not supplied with the kit. So I sanded a peice of MDF to the right shape and glUed it into position.

VOILA!!!

A finished set of legs. Next step, attaching the legs to the body. this should be FUN...

DAY 6: Attaching the legs to the body, detailing the legs, and detailing the ass. (6H)

When I attached the legs to the body, the hips didn't want to stay in place. They had a tendancy of sagging from the weight of the body. I didn't want to over tighten the screw, nor glue it in place. I told myself I need more friction....Then rubbed my scuffy face.....SAND PAPER!!!!

EDIT: The sand paper disks (150 grit) are glued into place. IE: I glued a disk on the harrier engine and the other on the hip plate. Once the glue was set, I screwed the two peices together. Friction O'max.

As for hiding the bolt heads, I decided to use what seemed to be the quickest solution. Styrene plates hollowed out in the back, giving some room for the bolt head to hide. stuck on with double face tape, incase I ever need to undo the legs.

The slot I mention in the pictures was an after thought. I looked at the movie and noticed how the slots were used, quite cool. It's too late for me to apply, but would be a great detail for anyone else.

Mommy and baby together, side by side. This isn't the kit I remember as a kid!!!

Any comments, I'd love to hear what I should change before I paint this sucker.

Lookin' good!

So the ball joints come with the kit? I haven't opened up all the baggies, yet...

Oh, and what is MDF?
 
Looks SOOOO COOOOOOL! Awesome work my man!
Since I'm building the same kit myself there's one question I would like to ask. Do you feel that the styrene hips are able to hold the weight of the kit without any problems? I was thinking of having them made from aluminum for added strenght since I'm building a inner structure for the body of metal sheets.

As for what is MDF....It's the greatest material on this planet!!!. It stands for Medium Density Fibre. It's wood dust glued together at high temp. Poster laminations are made with it. It's perfectly flat has no vains running through it, so it's great for sculpting. I call it really hard plasticine. I sculpt everything with it.

The supplied styrene hips are quite strong enough.

The weak point is where the hip meets the harrier engine. the weight of the whole body pushes down on the hips, making the hips pivot upwards, I realized there wasn't enought friction. Like I show in one of my pictures, I added sand paper between the hip and the harrier engine to add more friction, avoiding the sagging problem. It's a great solution and quick to make.


If I think it could be made in aluminium, sure, but it has it's good and bad points. You'd be able to mill the groove into the hip, But adding a thin sheet of styrene would do the same effect.

The problem if you choose to make the hip out of aluminium is that it's too rigid. I'm not sure if the harrier engines are too narrow or the feet are too big, but the feet bump into each other in certain positions. I personally would stay with the styrene. It's more flexible and can twist a bit, which allows you to get the AT-AT into some funkier poses.

If you want I can send you some pic to show you what I mean.

I know exactly what you're reffering to. That wont be a problem for me though since I'm actually building the entire inner structure (including the hip mounting points) like the studio model. I'm using real Harrier parts for my engines and the mounting points for the hips will be able to move side ways.

It's kind of hard to explain what I'm talking about!

The real models only used the Harrier engine to cover the hip mounting system and didn't attach to the Harrier engines.

My concern though is that styrene might be to brittle to hold the weight of the walker.

Originally, Ron was going to cast the hip peices out of resin. I told him the resin would break or warp with time. He opted with supplying the styrene for the hips instead.

Lookin great Pat! I was actually considering painting the pieces before I assemble them. I had one of those baby AT-AT's myself, when I was a kid. I was gonna search ebay for a new one, but discovered the ATATRON instead.

I believe I even have some of those sandpaper circles in my dremal kit, great tip.

Also, two things, 1) do you have any more of those MDF pieces? 2) I don't have any of those speaker grill bits, so if you still have extra please contact me.

Thanks
 
MDF can be had at most any hardware store. I'm sure you could score scraps from when they've had to trim sheets for customers.

Excellent work on the ATAT, Pat!
 
Hi guys

I forgot to post a picture of my ass. Here it is. It's not screen accurate, but it's average joe edition.

After recieving some helpful comments. I will be adding more details on the ass and the feet.

Keep those comments coming.
Pat
 
PLEASE NOTE I have edited the sand paper editiorial with additional info. Refer to top of page.

As for the MDF issue, my hardware store Home Depot sells MDF in smaller cut sheets. So what I've done is that I dought all the thicknesses they offer in 2 foot squares, just to have a cheap veriaty. 1/8 1/4 3/8 1/2 5/8 3/4 7/8 1" . Now I'm ready for any project.
