OK I’ll stop
maybe.
so I’ve managed to make some dents into the neck piece to get it to flex enough l, for my not so thick neck to get through it l, and it worked.
I made more dents than I thought I would at first, but it allowed to redistribute the tension and avoid cracking.
Might be enough for today. The next part, which I didn’t think would be the more demanding, is getting the jaw piece to connect correctly.
