I'm using a Bob Barrow's fiberglass nose bowl. This is a bit different than the Avipro but was made for use with the 13" CS splinner from Vans.
Drilled nosebowl for clecoes. Been struggling with how to hold the nosebowl halves together in the center, behind the spinner. Came across Bill D's (Bdflies) on the forum. Decided that would be my best chance for success. Stealing that good idea too. Basically the platenut is placed on the outside behind the spinner. A #8 hex head screw is accessed from the inside of the nosebowl with a socket srench. Thanks Bill!
Decided to mount the nosebowl to accommodate for future sag of the engine. Spinner to nosebowl clearance:
Top = 1/4" Center = 5/16" Bottom = 3/8"
Nosebowl was clamped in place with a shade to the high side for future engine sagging.
