Hello all,
O.K it would seem no one knows anything about those circles on the lower rudder. Somebody? As can be seen from the photos, Filling around the fillets and sanding back has given a nice smooth radius around the profiles where the appendages connect with the hull.
I then turned my attention to the further development of the missile deck top layer. As mentioned I will be placing a strip of Renshape on the top of the deck. This is where I will be putting most of the detail. There is very little detail on the sides of the missile deck. There are far less drainage holes and vents than on the Delta 3. I decided to make the strip about 5mm thick and so cut out a section from the block that I've got; I don't have a bandsaw or a circular saw that would make this job really easy. So I attacked it with a combination of Coping saw hacksaw and good old fashioned Tenon saws. Eventually separating the offending piece as needed. Once this was done I needed to sand the bottom side as smooth and as level as possible. The top or outer surface that was the outer surface of the block will become the top. It is machine cut and very flat.
Once cut out the profile needed to be cut and sanded. This featured a curved profile at the front as the front deck section narrows to meet the rear of the sail. The section also needs a curved surface with a pronounced chamfer as it moves down to meet the top structure that makes up the rest of the missile deck. I created a template by drawing the profile on both sides and then flipping to piece to check symmetry. anything that you can do to make symmetry checking easier. Do it. The first piece abruptly stops where the missile deck changes angle as it slowly slopes back and down towards the stern of the hull. A second piece being cut to create the Renshape bed that will run down to the stern.
One the Renshape tops had been sanded and made symmetrical, I started the development of the top details and also the missile door template. I started by making a template out of tracing paper off the original drawing. This would be made out of sheet brass. 1mm thick I would create it by cutting out the center and using an etching point around the inside of the template. Marking out the brass sheet I then drilled a series of holes around the inside of the piece and then once done took a fine file and smoothly made sure that the curves points created by drilling holes right next to each other were smoothed down until they complied with the profile of the template.
