Now that we are waiting for the epoxy to dry, there are a few things we can do now.  If you want to make the 3"/50 CAL Gun Turret turn by radio control there are a few things you will have to do now. 

  Find Frame 6.  If you wish to make the 3"/50 CAL Gun Turret turn by radio control you will need to make an "access" hole in Frame 6.   This access hole not only allows you to hook up a linkage to the turret, but it also allows you to add ballast in the bay between Frame 5 and Frame 6 if needed.

  Now, trace an outline of a center cutout on Frame 6.  Use the other frames as an

 

example.   After you have traced the  center cutout, cutout and remove the center material.  Save the removed plywood. (Doesn't have to be perfect)

Measure across the tops of frames 1 through 14 and make a mark at the exact center of the top of each frame.
