Before cutting the cowls, I begin by countersinking and scalloping the camlock support strips.



And the result after quite some time at the bench grinder.



Then I begin the lower cowl installation. The picture shows the first cut made yesterday on the lower cowl and it allows to insert the upper cowl.



Then the cutting goes in with first the lower parts and then the sides. Some tweaking to be done before I'm satisfied.



The picture shows a problem that appeared after the lower cowl was installed. The gap between the cowl and the spinner bulkhead is not constant and is at minimum.
The bulkhead is not really flat which is part of the problem but I might also slide the upper cowl slightly back before adjusting the lower cowl.
