Cuddy cabin cowling and anchor well

People who know me well are not surprised that I have decided to build the cuddy cabin main hull.  It's faster, cheaper and very fashionable with the large cockpit and ultra modern racing rig.  What finally closed the deal for me was the wonderful pictures of Loyd Crisp's (and his family) 'Stick Shift' in action.  Then,  as a testiment to the fact that you cannot make a good designer a manufacturing engineer for long (for the production F22),  there was the release of Ian Farrier's concept for the F32SR, which looks to me very much like a stretch F22.  

So, as I am  committed to getting this project completed before someone can build a F32SR, I moved forward this week by starting the cabin cowling and the anchor well parts for the main hull.  I do believe that after these are finished, I just have to review, inspect and finish the remaining flat panels.  Then, the next step is to cut the form frames for the main hull.

Above are the form frames for the blister cowling.  No battens to be used here.  But you say, 'what is a blister cowling?'  It's a removable shield that is placed over the cuddy cabin main hatch, so that spray and rain does not enter the cabin, as well as offer a bit more headroom.  I simply have to panel this shape with foam and fiberglass it.  No problem, eh!  

Above is the form frame for the anchor well.  This one looks fairly straight forward, although the one bend looks like I will have to use a heat gun for the first time.  

The above two pictures show my attempt at planking the cowling.  I took the designers advice to keep some of the strips to 25mm in width.  This is not for bending along the longitudinal axis but rather so the strip can flex transversely. Wider strips will not allow this.

I now plan to use my polyurethane construction glue to bond the strips together.  I'm hoping that the glue will drip through, lock to the frames below and allow me to remove all the screws for fairing and laminating.  This will be a matter for next weeks post.
