March 20th, 2006: Progress has continued well on this model. I got access to my new shop about three weeks ago, and since then I have begun working on this model in earnest (let's say from the beginning of March).
I began by deepening the longitudinal scribe lines in the hull which were supposed to depict the demarkation of the hull and fibreglass deck of the actual sub. The hull, as shipped, has a simple thin line. I wanted something far more realistic and separate looking. I began by running a small piece of hacksaw blade along the line (very carefully) until I had chewed into the gelcoat to the point where the blade was not so prone to slipping. After that, I angled the blade to the proper pitch (upwards and along the hull circumference). I then deepened the line until I'd cut almost through the entire thickness of the hull. From there, I used sandpaper on a piece of wooden paint stick dowelling to sand the lower edge until it was faired into the hull. The result? A nice, realistic demarkation between pressure hull and deck!
After that, I cut the forward section of hull from the lower hull, and the stern section from the upper. I will later bond each piece to their opposite mate to create a "Z-cut" hull. This should preserve the details along the front of the sub, and along the lower stern section once it is complete. NextI laid out the interior components to see how they would sit.
From there, I proceeded to work on the forward dive planes. They are connected with a single shaft just forward of the main drive battery. I mounted several pieces of the internals to the hull. In one of the pictures below, you can see a styrofoam blank that I created for the ballast tank. Since then, I located some 4.5" diameter plastic storm drain pipe that is close enough that it will work in my application and save me the hassle of having to build my own tank.
 I then concentrated on the rear planes and linkages. The solid rear planes were cut at the scribed lines. The leading edges of the planes themselves were rounded with by bench sander, and the accpeting edge of the plane housings were also rounded with my Dremel. The result is a smooth finish reminiscent of the original.
Each of the two planes were connected with a length of brass rods to ensure alignment while the glue set up. I'll simply leave this alignment brass inside when the model is buttoned up. Plans at this point are to run two separate linkages forwards to a single shaft that the servo will actuate, leaving the center of the hull clear for the drive shaft.
