Step 1: Stem Lashings
Here's how the stringers are lashed to the stem.
I trimmed the end of each stringer to lay against the stem with my pullsaw and knife.
Then I drilled two holes above and below each one. I lashed around each pair of stringers with 7 or 8 turns of polyester twine. I shoved a loop of wire under the lashing and pulled the loose ends through to finish the lashing.
I wasn't planning to do anything at all to the ends of the stringers.
I was going to leave them hanging out in space and not lash down the tips.
It felt like they'd break before they bent enough to reach the stem.
But I tied them bent and went away for a month. When I came back they bent to the stem easily.
So went ahead and lashed them to the stem.
Don't agonize over this part of the boat. You'll see when we stretch the skin over the frame it won't even touch the stringers here. And if it does, this part of the boat is above the waterline most of the time anyway.
