TRNS

Its been 10 days since I last posted and I have been working most days since......and its 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 havent 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.
