Covering Boards continued. 5.
I have tried to make the length of covering board to what I think would be possible in real life so the longest boards are around 20 feet long and from material that is not very wide the boards with a lot of curvature are shorter but wider.
A couple of problems have arisen, the first one I noticed a few weeks ago, this being that there is a gap between covering board and stringer because of the deck camber, bit of an oversight on my behalf. I had a few ideas one was to use filler to build up this area though I think it better to use strips of wood glued down then fared with a file or sanding block.
The other problem is how to make the tug stern this presents some challenges along with a rethink of build procedure, I originally thought I would make and fit the stanchions + covering boards then plank the bulwarks and lastly plank the deck, this has been scrapped and currently I am thinking of fitting covering boards and deck planking then fit stanchions and lastly plank the bulwarks, subject to change.
One reason for this is the aft stanchions lean inboard considerably therefore cannot be done the same way as the rest, if I tried to I would drill a hole through the hull not a good idea, some of these stanchions also have knees that straddle the covering board and a bit of the deck planking so as in real practice according to Ted Frost’s book the deck needs to be laid first.
In Ted Frost’s book he says the stern covering boards were made from 4” thick Oak due to this area being subjected to large amounts of pressure at times when going up to or in port, this being the whole reason for the tug stern.
I made a card template of the 3 last covering boards and glued them together to form one.
Then cut my interpretation of the scarf joint that joins the 3 pieces together, I am not sure if it is right though I think this joint might help prevent the pieces moving inwards if pushed from the outside.
I made a former to steam bend the center section on.
At the end of the day I had cut and pinned the 3 pieces in position though there is still some material to remove, better to sneak up on the final shape.
One thing that has been troubling me is the difference in thickness between most of the covering boards and these beefy stern boards, my main concern being how did the deck sit up against the thick boards was it flush?
The plans show a raised stern piece.
I was going to simply put a chamfer on to blend the two together, then while packing up for the day I looked at one of the sketches in Teds book and to my horror/surprise the thicker boards remain at deck level the extra 1.5 inches being let into the hull. Why hadn't I noticed this earlier, the only concession is nothing is glued in place yet.
From old photos earlier in the build, ( I had forgotten what I had done ) I should be able to remove some material without compromising the strength.
That’s it for the moment, thanks for having a look.
I welcome any helpful comments and suggestions.
Cheers,
Stephen.
