Part 3 - Propeller Shrouds

These are the beginnings of the propeller shrouds, and because they´re part of the outside hull I decided to include them here. The scale shrouds will eventually be 2½" in diameter X 1½" in depth with a 2 1/8" hole in the middle. I cut 8 pieces of Celtec 3 inches square and then cut a 2" hole in the center (or almost center) of each. I had to cut them individually because my hole drill wouldn't go through 4 pieces at a time, and the sheet metal bit heats up pretty quickly. I didn´t want to melt the Celtec and ruin the holes. Anyway, after drilling the pieces they were glued together with CA glue and clamped until dry.
	I just happened to have an old hand drill grinding wheel measuring just over 2" in diameter. I used it to even the inside hole before cutting the shroud outline on the band saw. The next step in this process will be to file and smooth the inner hole to 2 1/8´ diameter providing for my 2" Raboesch Brass 6-Blade Propellers (B-Type). I'll include a pic of that and the final shaping of the outside shroud later!
But, before final shaping I have to manufacture several more parts for the stern. Here you can see the piece that will connect the shrouds together and be used to mount the entire structure to the hull. The rounded, rectangular hole in the middle will allow access to the stern plane linkage.
	I´m not real sure what the technical name for these are, but for now I´ll call them stern fins. They will eventually be permanently attached to the propeller shrouds and hull, and they will also house the stern plane hinge mechanism. As with all of the other parts, they were cut from a piece of Celtec (did I tell you how much I love this stuff?)
This pic is a little blurry, but you can still see that I´ve shaped and sanded the shrouds.
	I´ve temporarily bolted the shrouds to the hull to hold them in place while connecting the fins. I plan to use another bolt/nut to secure the bottom. Additionally, there will be a hole drilled into the hull to accommodate the stern plane servo rod.
Ok, the shrouds have been bolted to the hull and everything is now in place. I installed another bolt/nut to secure the bottom of the shroud unit, and I drilled an additional hole into the hull to accommodate the stern plane servo rod.
	Bondo® ... sanding ... Bondo® ... sanding ... Bondo® ... sanding ... to fill in the gaps and contour the corners. I will probably do so more Bondo® ... sanding ... before final painting, but I wanted to test the finish by spraying a coat of primer on first. Next Step - Part 4 - Rudders and associated hardware
