Moving on to the front 4 brackets on the horizontal split line.
I countersunk the brackets and the lower cowl #40 attach holes. After that I cleaned and primed the brackets.
As I head to wait some time for the parts to dry, I used the time to cleanup and smoothen the inner spinner ring. on the top cowl.
After the brackets had dried, rivetted them on the lower cowling. The front bracket is quite close to the air cooling ring and will be partly covered in epoxy as I will install the rings but there is enough space to clear the receptacle. The closer to the front the fastener is, the better it will be in my humble opinion.
