The
Allard's monocoque was manufactured in upper and lower outer sections,
and upper and lower inner sections. So in essence you had
molded
surfaces inside and outside. This contrasts with the usual
method
of a female mold which results in an un-molded inner surface
finish. All
four monocoque pieces were then bonded
into one. This is a photo looking at the bottom of the male form for
the
lower inner monocoque section with the upper half in place. |
This (right)
is the completed lower inner monocoque prior to assembly (taken off the
male mold form in the image above). The upper
inner skin was simply the inner panel above the driver's legs. |
Prior
to the assembly of the monocoque, the steel roll over hoop was bolted
to
the lower inner tub section and then the upper and lower outer halves
were
assembled, capturing the roll over hoop and making for a
particularly
strong and homogenous chassis. |
