Rocking and rollin’ away on this Seawolf...We’re starting to get a nice pace on her. Not breakneck, but not nothing like before, lol!
A full day and a half was spent on plug surface preparation getting it ready for intermediate moulding. No detailing has been applied as it’s much easier to polish the plug if you don’t have to worry about wrecking that stuff. The same procedure was used here as was used multiple times on the Permit/Jack project.
Now because I want to do intermediate mould-work at the same time I am working hard on the sail. Probably one of the more complex shapes on this submarine is the fillet on the front of the sail that serves as streamlining and helps counter the snap roll phenomenon.
I use the same technique as before with the basic shape:
I glue the side view part of the plan to a carefully squared up piece of Renshape. I’ll cut the bottom, back and front off carefully using the scroll saw on slow, then hot melt it all back together.
I then glue the top profile of the fillet on – care was taken to get it perfectly aligned with the side profile location.
Now I have the basic shape...
On to enabling myself to fit this part properly. I’ll adhere the top-down profile to some cereal box cardboard, and then the bottom of the side profile to some very thick, rigid cardboard. I love cardboard; it’s cheap and plentiful building material. I liked using it as a kid to make laminated finger skateboards and cardboard half pipes to sell them for exorbitant prices to my friends!
The sail Is hot melted to the top-down profile, and then this is hot melted to the bottom profile. Remember, the sail will not be perfectly flat against the round hull. Only when it is hollow will it fit right, therefore the bottom will have a kind of funny look to it for now.
The fit of the fillet was pretty good right off the get-go. Only a little sanding was needed to get the fit right.
Once fit, I taped off the line that will represent the slight demarcation between the sail and the fillet. Tamiya tape was used here, cut into very thin slices.
Looking at lots of pictures of the fillet shape for reference, I simply used sandpaper to sculpt the rough shape.
More to come,
