CVI. Construyendo Un Monstruo Gigante Pero Amable Que Se Llama "Al"

Building a Giant But Friendly Monster Called "Al"

The small model is made of clay. One
of the first steps in this project was
determining the size of the finished
piece, and thus the scale ratio: 1:12.
For the past three months much of the free time I'd previously used to write in this blog has been spent in my recently renovated taller, or workshop.  I've been working on a large alebrije, a fantastical creature of a type popular here in Mexico. Once finished--and its completion date keeps getting rolled back--Al will go up on our rooftop where he'll lean over its parapet looking down at the street traffic below.

Progress has been much slower than anticipated for several reasons. I've been scaling up from a small model, and have never before attempted anything of this size and complexity. Deciding upon, and then finding, the materials and tools I need has taken a lot of time, due to fewer and different things being available, the language barrier and my lack of a car.

Big Al will primarily be painted turquoise, span over 4 feet
from hand to hand, and rise almost 3 feet above the parapet,
sticking several feet over its edge.
The primary medium I finally decided on is one-inch thick, pink polyurethane insulating foam in 4' X 8' sheets. It took awhile to find it. After some rigorous math to determine how much was needed I ordered ten sheets delivered from the nearest of five Guadalajara Home Depot stores found online. I would have preferred three-inch thick sheets like I've used in the States for carving, but insulation requirements here are not as severe as up north and this was lo más grueso (the thickest) available locally.

Some friends brought back a half dozen glue cartridges (cartuchos de pegemento) from Texas, but that was soon used up. Fortunately local ferreterias, AKA hardware stores, carry a similar product called No Más Clavos that seems up to the task of bonding the insulation sheets into a secure laminate. Likewise I bought a utility knife with a blade that can be extended far enough to be useful cutting multiple sheets. A cepillo de alambre (wire brush) has proved a very excellent tool for shaping the foam. Plus, toothpicks have been indispensable.

Now that a good deal of the sculpting is finished it doesn't seem like much of a big deal, but at each new step along the way I've been consumed by consideration of all the practicalities. The decisions about what needed doing next and how to do it originally assumed monumental proportions in my obsessive 3AM mind. As the work has progressed though--and of course I've made mistakes--each miscue has helped me loosen up a bit and realize that que sera, sera, which is Mexican for "No worries".

Creating the blocky laminate of Al's body and arms has mostly involved numerous measurements of the small model and an equal number of multiplications by twelve to achieve the same look at a bigger scale--all very left-brain type of activities. And then cutting to measure through many meters of foam taking care not slice off part of a finger.

The wire brush, upper right, is the primary tool for shaping the
foam. I got carried away and removed too much around where
the PVC shoulders jut out from the body. The channels around
the pipe were filled will spray foam and a 4" top added.
After I finished the body's laminate, and before attaching the arms, I used the wire brush to smooth the many overlapped edges and create the shape of Al's upper torso. Viewing the sinuous convex and concave lines was almost shamefully satisfying, but I soon discovered that I should have postponed this gratification until the entire figure was finished and looking like some kind of Lego creature. As it was, I took off too much foam so had to apply additional cuboids of polyurethane where the PVC armature attaches to the body.

I've just finished covering those arms with oblongs of foam sheet, each about the size of a large paperback book. This involved challenging calculations to determine the odd angles at which I needed to cut in order to accommodate the twists and turns of the arm "bones". And then actually making those cuts on cubes of foam. All that remains of this portion of the obra, or piece of work, is to complete the laminate for Al's elongated neck and head--about 1' X 2' X 3'. Then I can indulge myself shaping and smoothing the contours, creating the expressive details of the mouth, eyes, and hands.

This is about where I am now. Note the small model on top of
Big Al. Al's neck and head will be skewered by the protruding
PVC pipe.
When I'm satisfied with the sculpture and feel good about Al's size and look--including how he'll fit at the parapet--I'll try to figure out a coating for the water-resistant foam that will provide a good base to begin the painting part of the project. Alebrijes achieve much of their effect from intricately painted designs and wild colors as the one pictured below can attest. That will be a whole new and fun thing to learn and practice.

I figure the finished whole will weigh about fifty pounds. Hoisting it up to the roof will be done with block and tackle. I'm eagerly anticipating that event!


This is an carved wooden alebrije made by Antonio Mandarin from Arrozola, Oaxaca. I've had him for about twenty years.
He's about six inches tall.
