This blog is here to document my latest 2009 project, an extensive recreation of the Disney 1954 movie 20,000 Leagues Under The Sea through a series of detailed miniature dioramas, all contained under my model railroad table. This will be a "crawl-thru" type attraction (What is a crawl-thru? Read about it here).

Like Disney, I usually tend to keep everything under-wraps until I unveil the final product at the end. However, by keeping everything a secret, I end up not taking any photos of my projects and it is often disappointing to not have any documentation in the end showing how everything worked and was constructed. This time, however, I will document every step in the process of the creation of the project with photos and drawings (and maybe some video) illustrating each leg of the construction. Even though the posts here will be chock-full of spoilers, it will show the amount of work that goes into this and other projects--which is often under-appreciated.

This blog includes weekly updates that consisted of notes, ideas, photos, and maybe some video of what was worked on each week up until the estimated completion date of December 2009. (It was officially finished on December 10th, 2009).

10/26/09--Squid Construction, doors

Brief update this week. The squid is complete, just as I had hoped. I didn't get around to the crew members battling it, but that that will be the focus this week as well as finishing up the entire scene.

Last week I showed the first tentacle made for the squid and soon after that, 6 more were made. I'm only going for 7 tentacles out of 10 at this point, though I might add more later on. The reason for that is that I wasn't sure if you were going to see them all during the flashes of lightning. After a few tests, it turns out that you can!

Once the tentacles were baked and hardened, all the joints and gaps were filled with self-hardening clay. Forgetting that is has that quality, the clay cracked like crazy when it dried because of the rigid structure. So I filled in the cracked and joints with epoxy putty. (Which results in the different shades in the picture below).

Once the joints hardened, more details like the eye and mouth were made out of sculpey and glued on. Below is a shot of the squid just before painting. The rough texture was achieved by torching the surface of the putty, which actually works in this situation.

The color of the squid in the movie is really hard to determine. After some studying of the dark film footage, and some consideration of my own preference, I decided to paint the squid a dark purple. I've always associated the squid with being a red color, after seeing the "sunset squid" lost footage. I compromised that image by darkening it and I got purple. The reason also having it purple is so the viewer can distinguish the squid from the backdrop a tad easier because of the difference in hues. Just for fun, I also painted the eye with glow-in-the-dark paint!

The squid is currently being installed and at some point I should get started on the characters. After that installation of the effects will go in and some "Mod Podge Water" will be drenched all over the set.

Since the entire scene is static, I've come up with a way of giving the illusion of movement during the lightning flashes. In a couple of tests that I did, I rigged two strobe lights, turned on and off by a motorized cam, on two opposite sides of the squid. I set them at different flash speeds and the results create a striking look (no pun intended). The rapid change between the light sources looks incredible and it gives it the slight illusion of movement.

In addition to working on the squid, I've also finally finished my first door to the attraction. My original entrances to the table attractions have always been strips of trashbag. While they worked for their time, they don't seem to last that long and aren't the most stremlined and slick looking "doors". This time I've devised operation sliding doors (I was originally going to employ a set of double doors, only to find that they take up a lot of room). Once I had a smooth working door, I figured out how to make it run on it's own. The goal was to have the door open at the push of a button, stay open at time interval, and close all automatically on it's own. However, the propulsion of the door was the hardest part. I went through 3-4 versions of a motor set up and the best one was loud, noisy, jerky, and broke really easily. That doesn't help when I need smooth and quiet operating doors. Basically I had the sliding door on a track being pulled by fishing line by two motors. A timer relay would turn either motor on, opening or closing the door.

I later compromised and not have the entire door motorized. To put it in simpler terms, the sliding door is on a counterweight, push the door open and the weight pulls it closed. However, I added a little more to it. Once the door is open via a line pulled by the viewer entering or exiting, the cable operating the door has a catch that comes in contact with a latch, like a zip-tie. A motor allows this contact to happen because the latch was lowered by the motor once a reed switch triggered the relay powering the motor. Once the timer expires, the motor power is cut allowing a lever to drop, raising the latch and releasing the cable catch allowing the door to close via gravity on the counterweight. It sounds pretty confusing without and visual reference, but I might do a video demonstrating the door since it is a clever piece of mechanics that I've done.

This kind of operation is virtually silent and it's actually safer since the door can be stopped from closing easily because it's only on a counterweight; while if I had the old motorized door, the door would close whether or not someone was in the doorway.

Your crawl-thru is progressing really well. I'm kind surprised that you didn't animate the squid tentacles, but your description of the strobe light sounds wonderful and fine. The color for the squid should be real fun, and it's good that it's a different color from the b.g. I like that you used a counterweight for the door. I'd be concerned if you motorized a door to open and close without some sort of sensor for the humans. Can't wait for your next post! Oh, and i hope you saw various halloween shows. I always get inspired from other's shows.

Thanks! I appreciate the feedback.

Everything that is modified and changed is done for a reason!

gerG said...

Yeah! And i like that process of modification and change. It's growth and it makes the project live. It's wonderful to see your thoughts and process.

Hey, will you have a crawl-thru party? Will people be able to see your work in person sometime?


Sam Towler said...

That's one of the reasons why I'm documenting every step because it is pretty interesting to see the growth of it and have it go off in different directions at the same time.

I will have some sort of "crawl-thru party", but only for our relatives and close friends as a tie in for an annual Christmas party. I will document the entire project the best that I can when I'm finished so that the internet folks can get a very similar experience of "crawling through". (I'm also experimenting with Quicktime VR's which might be kind of neat).

It'll be great to see that christmas post! Look forward to it, and good luck on your project.
