This piece was the most difficult to fit so I thought I would dedicate a post to how I was able to get this piece twisted into shape.
I used the same process that I described in the previous post to get a rough cut on the plywood.
I put a few screws in the bottom and the bow to hold the material in place. I used a series of clamps to be able to pull the material down closer to the Frames mid way down the sheet and towards the aft end. I couldnt get it all the way down but close. An old jib sheet was used too !!
Starting from the bow I used a series of different length screws to achieve the full twist. These were screwed into the lower 50mm stringer. Shorter screws to to the bow and up to a 150mm long #8 screw at the aft end.
Little by little, I keep slowly tightening up the screws to get the plywood closer to the frames. You can see the twist forming in the following photos.
The portside bow chine plywood was a bit easier because I could use clamps to pull the plywood down closer to the Frames because there wasnt any plywood covering that area.
I left the plywood full screwed down for 2 days to let it conform to its new shape. From there I unscrewed it and glued it down using the West System epoxy.
