"If you are going to take your precious free time for months and build something, there is no excuse for second-rate work. You cannot claim client deadlines or lousy budget, since you have control over both of them.

"The opportunities to do the great defining pieces of your career come around once every couple of years. Are you going to waste those rare chances on a less-than-grand endeavor?"

Kim’s recommendations

Sculpting supplies

I use "Le Beau Touche" modeling clay from Chavant. This plasticine goes for approximately $4/pound. It is mid-level hardness, formulated for northern climates.

I make molds using these materials from Smooth-On corporation:

Mold Max 30 high-tear-strength silicone rubber
Plasti-Paste Trowelable Plastic
Thi-Vex II Silicone Thickener (thixotropic agent)

My supplier here in Washington state is Far West Materials.

(By the way, Smooth-On's site offers amazing must-see moldmaking video instructions. I wish I'd had these when I was starting out!)

I strengthen the mold rubber by adding small amounts of Fibermesh 150 e3 polypropylene multifilament fiber (often called "stealth fiber"), sold by concrete suppliers . Here in Seattle I use Glacier Northwest.

Glue gun

My hot glue gun, the 3M Scotch-Weld Hot Melt Applicator TC, costs about $100-140 and is well worth it. I’ve burned up seven ordinary $25 glue guns in the past two years. This orange beast can effortlessly put out several pounds of glue a minute. It requires specific shaped glue sticks available in 11-pound boxes. You can find great deals on the web.

Mounting the small parts

Posted by Allen | Technique | Tuesday 6 January 2009 8:34 pm

The small parts — fingers, ears, and fin bases — all get their own molds. We use cheap chopsticks to anchor them to sheets of 3/4-inch plywood.

Specific techniques after the jump.

Drive the chopsticks about an inch into the clay part, then cut the exposed remainder 3″ from the clay.

Drill holes in the plywood with a 13/64″ bit. This is just slightly smaller than the sticks; it makes for a really strong fit. Push the sticks aggressively into the holes. For the heavier parts, use three or more sticks.

Also, instead of using one large ungainly sheet of plywood, use a bunch of smaller ones (16×12″-ish). These are easier to handle in a limited space, and more people can work on individual “sets.”
