The Nautilus originally went to sea with twin 5-blade screws in 1958, by the mid-1960s she had been converted to utilize 2 x 7-blade screws following the "Blade Count" findings discovered during Skipjack development. These replace the impossible-to-assemble etched-brass blades you're somehow supposed to attach to the screw bosses mounted on the rear horizontal fins. I haven't printed a shaft on these, and the idea is to cut off the molded-in screw boss on the Mikro-Mir part and then pop these on the end. My glue of choice for these would be simple white glue, a small dab on the end, as I see these as a final-item-to-add part and I've seen superglue blush paint work.Instructions on how to remove the screw from the sprue:Given the thin section of the screw blades, some care will need to be taken when removing the screw from the sprue. The resin is by nature brittle, but the sprue is thinnest where it attaches to the screw blade as it attaches at a point, by design. The best practice is to place your flush cut pliers flush up against the bottom of the screw blade, at the point where the sprue attaches, and trim there. Do not trim from the bottom, larger diameter end of the sprue. I've found that the shock of shearing the larger diameter sprue at the bottom can ping the propeller blades right off the screw boss. Work outboard to inboard, that is, trim the outboard sprues first, and then the inboard. As the outboard sprues can obscure the inboard ones, after I've detached it from the screw blade, I then trim it off the base to allow access to the sprues deeper in. Patience and care needs to be taken. Once trimmed, you'll often have a small residual sprue-nub on each propeller blade. I then use a very narrow sanding stick to carefully sand the nub down (I use the flexible/soft and narrow sanding sticks that can be purchased at just about any Hobby Lobby in the U.S.). Why do I sell 2 units as the minimum quantity? Because ultimately the material is brittle and if care is not taken then you can break the parts. Now, this resin is toughened for sure and I've been pleasantly surprised at how much battering (ooops, dropped it on the floor, ooops, slipped) it can take. But it isn't necessarily about the material as many are familiar with resin kits and this is little different. It's more about how thin these sections have been printed. And as modeling is about enjoyment, I'd hate for someone to purchase these as 1 unit and immediately break the parts and be back to square one. I think having 2 available at least gives you a much better shot. And if you only need 1, share the other with a friend! I will combine shipping!
