A question for other Easy builders. Peter wrote in his instructions that all corners must be filleted but I have not heard of anyone filleting the under side of the stringers before you roll the hulls. Has anyone done that and is it nessissary ?

Cheers, Dean

Hi Dean,
Just trying to remember what we did ...
A lot of the stringers end up being filleted by default, during the fit-out, as the structural shelves and benches are installed. Also, the underfloor areas that are fiberglassed, requires filleting to provide a radius for laying the glass.

In the areas where the stringers are exposed, we filleted the underside mostly because it looks much better.

Personly (other than the edge-mounted upper stringer) I don't think there is any structural purpose to do the undersides of the stringers, the 42mm surface area provides copious glue coverage, but other than adding a heap of time, I guess it couldn't hurt.

Hope you are well, and the build is progressing well.

Pete.
