Now that I have arched my back, I find that I have a hairline gap between the halves in the bottom 3 1/2 inches . Which, I guess means that I had some shrinkage. I originally glued this in July (75%+ humidity) and arched it last week February (40% humidity). Is that enough? I re-glued - clamped but,,, it popped open (same length).
Top is fine, glued the same time.
I expect it is better to open now, re-plane and re-glue but I thought I'd ask first. Is that correct? Or should I rough-out the inside first?
Thanks,
Regis
