securing the half barrel section of fuselage to a track such that a concavity of the half barrel section faces a factory floor, and bearing edges of the half barrel section contact the track;
a drive unit micropulsing the half barrel section along the track in a process direction;
enforcing an inner mold line and an outer mold line on a piecewise portion of the half barrel section via:
a first arch comprising first wheels extending from the first arch enforcing a desired contour upon the inner mold line; and
a second arch further comprising second wheels descending from the second arch and enforcing a desired contour upon the outer mold line to define a desired contour for the half barrel section; and

performing work on the piecewise portion of the half barrel section while the inner mold line and outer mold line are enforced.
