I want to have a two piece nosebowl for my homebuilt w/ Lyc O-235 L2C. I already have a standard Lyc nosebowl from ACS: http://www.aircraftspruce.com/catalog/appages/mc3a.php
The two piece nosebowl That ACS offers is very expensive and doesn't work for my application as it is set up for a 14" spinner and my spinner is 10" and that's what I need for my Sensenich 2EK composite ground adjustable prop. I would like to make a two piece nosebowl out of my one piece. It's easy enough to cut it across the middle of the air inlets. What would be missing is the "flange' that the other half must attach to.
To create this flange I am thinking I could add a fiberglass flange...or rivet on strips of aluminum, maybe .040 to accomplish the same thing. One of my concens about adding the fiberglass is that the flange wouldn't be an integral part of the existing fiberglass bowl and would essentially be a patch that is glassed in. I'm thinking aluminum might be stronger, either riveted in or attached with 8/32 nuts and bolts with a decent size washer on the the fiberglass side.
The actual areas that have to be flanged are not big, there are four locations across the air inlets, the biggest being 4 or 5" wide.
Has anyone made their own and if so how and how has it held up?
Any thoughts or comments on which of my methods might be better/stronger?
Or...a source for a two piece nosebowl that would work with an O-235 with a 10" spinner.
