Just one or two questions ;
What do you mean by 'carbon fill' ?
Is that some wood at the root ?

Brian,

Carbon fill is chopped carbon cloth, roving, whatever is too small to be used whole. I cut it about 1/8-1/4" lengths and mix it with epoxy to a thin peanut butter consistency. This mix is the fill. Some people will use glass here and that works okay too.

The mounting boxes or sockets if you will that house and support the struts at the fuse are made of a/c birch plywood. Once that's done, the sockets are wrapped with carbon roving to about 45K-60K filaments and allowed to cure. Then the sockets are fitted into the fuse holes with gear in place and pinned down to assure perfect fit, and epoxied with more carbon fill all around. The sockets are trimmed flush and painted to match the fuse.
