to keep you entertained : how I glued the bow halves together.
Both halves are a bit warped but I need to line up the weld lines.
what to do ?
I drilled small holes next to each other, in each hull halve. insert steel wire
and turn the ends of the steel wire. this gave a solid fit, with which I could now
continue with the polyester.
Due to my ineptness both hull halves vary a lot in thickness along the bow.
And I learned that that means air pockets when applying
the glass mat.
So, I mixed the poly, then added loose 5mm strands (I have a bag full of that stuff) until the mix was fairly dry.
This mix was put in the bow and thumped into submission with a paintbrush.
Then I covered the whole inside of the bow (I had the hull positioned under an angle so the bow was level) with an old plastic bag (a ziploc bag where the glass cloth had been sold in). on the bag some sand to distribute the pressure, and on that a large flagstone.
The result was a smooth and solid layer of poly in the bow.
I had the outside of the bow taped off, so the surplus resin has filled the gaps between the hull halves nicely
I'll now be working my way back to the tail, getting the hull halves to match...
<edit> gravel in the ziploc bag also works nicely to compress the poly.
