The keel will be 150mm wide hardwood, the most important holes are the ones in frame nine and ten which will pass each side of the fibreglass tube the propeller shaft will run through.
Below is a picture of the fibreglass tube, 50mm external circumference:
Also made up a template of the keel, I am thinking steel keel box filled with lead ingots at this stage:
Took some deep breaths, used a square and the frames to try and get the holes as vertical as possible and drilled them. Ones at the front and where the keel will go are 10mm, down the aft 8mm.
Frame 2 10mm hole:
The stem was laminated at the start of the build and incorporated into the hull with stringers and finally planking. Now that the sides are done it was time to cover it with hardwood and continue it up over the bottom where it will meet the keel. I got 90mm wide strips delivered, plan called for 5 x 5mm but my supplier could only do 8mm. Final result is still 24mm or just short of an inch thick so I think it will be okay.
A piece of hardwood was needed to fill in a space where the ply bottom finished (had to meet a hardwood cross piece at the other end of it).
Nails were removed once dry, the front (left as you look) planed down to an angle. Managed to plane a bit off the end of my finger but only minor. Made me pay attention though, it has been a while since I used the electric plane. Then the first layer went on. Started to pull down the high end to the right angle, snapped it in half at the bend. After a panic attack I realised I would have to use the snapped piece in the middle of the three. I had previously seen on the woodenboat forum (where I get all my boat building advice from!) about bending wood. Marked each end of the curved area, wrapped it in a hand towel and poured boiling water over each side and let it sit. After a few minutes while still hot bent it around the curve, screwed in place and left it for the epoxy/glue powder to set. Worked a treat.
Cut a fill in piece of hardwood to fit on top of the first to support the cap, pulled it down with a strap and the second layer went on in two bits, join is about half way so that the curve and top is one piece. Wrapped some cling wrap over where it will be layered into the keel, you will understand later.
Then the final piece:
And in close up, note the extra hardwood packing piece:
Filled the screw holes (screws were removed once each layer had set and re used so there are no screws in the cap anywhere) and blended the hull join with filler powder. Checked my drawings and plans, and cut off the cap. After a bit of sanding and clean up this is the result:
Close up, the cut out bit is where I had the cling wrap so the first and second layer would not stick together:
Cap to hull filled and sanded:
And looking back along the hull. Don't worry about the lean on the back threaded rods, it is 8mm rod in 10mm holes so there is a lot of movement. The first one is 10mm rod in 10mm hole and is standing nearly perfectly. I am sure they are not perfectly level each direction though I must admit.
