So, I used some hilariously low quality wood on the frame. In several spots it's split. Or cracked.
This does not worry me as the frame very efficiently transfers stress to other slats if one breaks. However, I would like to repair those broken, or weak slats. The method I'm choosing to do this, is superglue, and splint slats.
I bought the glue, and 900 yards of thread today. Hopefully I'll get to use both.
