Hi all. Are the offsets in FF1 to the outside of the stringers or the outside of the frames?

Hi! I got the book Fuselage Frame Boats and started going over the offsets for Curlew.

The illustration of how to draw the frame shows the stringers flush with the outside edge of the frames but the photos all show the stringers proud of the frames by 1/8" or so.

So do you make the stringers bigger or the notches shallower? Or do the offsets show the outside of the stringers and the frames get trimmed back? This is separate from the relief curves cut for the skin bowing in, that part is clear and not critical to the lines.

 

Thanks for your help!!

Neither.

 

You just make sure the frame corners are either flush or slightly lower than the face of the stringers.
