The Rocket cowl nosebowls are all moulded slightly out of alignment, so I measured the clearance from the spinner and built the lower area up by another 7mm. I added a number of countersunk brass screws to ensure the epoxy and Aerosil has something substantial to key to. Trimming the screws to length doubled as a support for a plastic board used to flatten and even the front-facing surface. I took the opportunity to improve the match of the air intake fitment as well.
