the exact position of the cowling screws are determined to ensure even
spacing.
g) Dont trim or fix the scuttle to the door pillars just yet as some final adjustment
will be required to ensure perfect alignment of cowlings and spinner,. Hold it in
position for now with some tape and clamps in the position shown below
Figure 191 scuttle positioning
– dont trim overlap yet, and clamp in position with upper edge
around 500mm from top of door pillar tube (TU34 (note
– some sanding of top edge of scuttle
may be encessary to acheive a symettrical measurement
– and may not be exactly 500mm).
h) Firewall halves can be rivetted in position now (short 4mm bolts can
alternatively be used if desired), and the small closure panels can be rivetted
in position now or left until engine ancillaries are all fitted
– dont forget them!

this early stage or applied near to finish of build. Further sealing grommets can
be fitted if desired as in fig above

leather etc.
