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.

We only did small glue fillets either side of the stringer, except for stringers that were used for floors, cupboards or shelves. Additionally, we lined many visual (ie not in the cupboards) internal sides with 6mm (well resined the sealed cavities). Ensure that you keep it as clean and smooth inside as you can, cleaning up any resin runs etc as soon as they occur. It will save you hours of prep later...😤.
