Fairing Keel, fitting Centre Board & Sanding Hull

It's been 10 days since I last posted and I have been working most days since......and it's difficult to see the progress.  Sanding and fairing is a slow process.  I had no major issues to fair, other than the tail of the lead keel was veering to starboard slightly, so I made a plastic shuttering and filled with wood flour thickened epoxy.
That left a remarkably glass like finish.

I took several passes of creating a smooth radius fillet between the hull and keel with fairing epoxy, using a variety of sized tubes to create the radius and the sanding with the same tubes covered in 180 and 240 grit paper.  Eventually  I got a passable result.

Next  I went about installing the centreboard.  I measured carefully from the plans where to drill the pivot pins hole in the lead.  I clamped the trunk cap onto the trunk with a 30mm piece of timber in the slot so that the CB would rest in the truck at the planned level, when it is fully hoisted.
I took lines form the existing hole in the CB and extended them to the bottom of the CB where I could see them in order to line up with where I needed to drill the lead.

Armed with my trusty auger bit and brace, Siobhan helped my sight up the bit so that I drilled a reasonably straight and level hole across the lead.  When I first fitted the CB, it was inclined to sit proud from the lead, at a point 20" from the pivot point, where is was sufficiently recessed.
So I had drilled the hole at the correct depth, but for some reason which I haven't quite figured, the knuckle on the CB was hitting the inside of the keel preventing it coming up (or down depending on your perspective).  I had to relieve some 1/2" from the knuckle of the CB which then allowed it sit home safely contained below the bottom of the lead.

A delivery arrived from Classic Marine UK today which contained my standing and running rigging gear.  I'm really looking forward to fitting all these goodies!  But first I need to push ahead with painting the hull.  I spent most of Saturday vacuuming around the shop and yesterday Brian and I did a final sanding then hung light polythene as a tent over the boat.

So tonight, I took the plunge and having tacked the entire hull, put on a thinned coat of underwater Hempel primer.  It's like a silver paint and dried fairly quickly,  I just painted the hull below the water line, as I have a separate primer for above the waterline.  I'm not sure whether I am over complicating the matter with two different primers on the exterior of the hull - if anyone has any suggestions please comment below.

  1. Paul,
    She is looking superb with a coat of primer.
    The pics are really helpful to me, particularly the close up of the deadwood on the keel, which plan to attack next.
    I have spent a long time 'reading' the plans for the deadwood. I appears John left out one of the sizes for the deadwood timber as he says six pieces and only lists sizes for five.
    As a consequence of this and because of the time I seam to waste looking for drawings and details of a particular part for the boat, I have made a spreadsheet of every item and have columns showing what page of the Specifications & Parts it can be found and all drawings that show it. You can then sort by Part No, Name, Specifications etc. Makes find info a breeze.
    It's probably a bit late for you, but if you would like a copy I am happy to email it to you.

    Pete.

  2. Pete,

    Thanks for the kind comments!

    I sent you a separate email on how I managed to make the deadwood - which is in an earlier post.

    Regarding the spreadsheet - i'd welcome a copy - I still have quite a bit to do, so it could be very useful.

    I have since put on an initial top coat, but I'm disappointed with the number of runs with the first cost - especially at the bow where the laps get finer at the gains - the paint seemed more inclined to run from one plank to the next. I will have to wait until it's dry and sand it back and try again!

    All the best


    Paul
