Gato Torpedo Door - Revell

[Scott T]

Here is an idea for activating the doors on the Revell Gato model.

Doors in closed position. Needs a little tweaking.


Upper tube door open.

Doors mounted to paper arms.
These will be made from plastic with some type of hinge at folds



Center door opened by pulling arm to rear.
This arm mechanism pulls down the centerline.

I like it! Very simple and easy to implement!

Some progress.

Made a back plate to guide the arms.




Made ramp to attach to door with holes to accept silicone glue.

Put holes in back surface of door to
glue into.

Taped door into position to align for glueing.

Door glued to pivot ramp.

Found out ramp position did not work correctly.
So I modified the ramp as seen in last picture then reinstalled.
Door shown in closed then open position.

So the plan is to activate the door in this motion which also will allow the addition of
the torpedo tube door. If this does not pan out then I can use the idea already posted.
This site also has accurized spoon and square doors.

Hmm! Rather than use a stiff board to pull the door in and out ---
Why not a weak spring to keep it out, and a string to pull it in. There would need to be a vertical rod for the string to go round. This would be placed in the center of the boat vertically. Both port and starboard strings could go round this pole/rod and straight to the servo.

Or you could extend the length of the door forward, and then use a ram to shut it. Have the door pivot on a rod at the extension. The ram rod would go straight to the breach, so as it slid, the door opened.

I like these ideas. Maybe a combination of the ideas the hinge secured at the back and
a string over the rod to pull it forward. So Kazzer what did you use to draw your illustrations?
