<u>Step 8</u>: (continued)

Use your microballoons mixture to start filling in areas with sharp, compound curves; narrow, hard to get to areas; and to radius those corners.

Now I'm begining to work on the fuses. Pictured below, is me filling in the sharp angles around the tail section of my P-39.

The first picture shows both halves of the mold. Note the sharp angles and compound curves around the recessed stab in my mold on the left side, and how I am able to fill in and smooth them out on the right side.

The second picture shows how I use the curvature of the end of a popsicle stick to form a smooth radius in the corners. If you want a bigger radius, use a tongue depresser, rounded rubber squeegee, or similar relatively soft material. Note that I am gently scraping the sides of the mold. Had I not putthat thinnedlayer of epoxy down, I'd be scraping up my PVA now. See, there <u>IS</u> a method to my madness!

The third picture shows the "trail" of filler left at each side of the radius that will need to be cleaned up or smoothed out; or this could cause trouble with getting the F.G. (fiberglass) cloth to lie down cleanly.
