At 16:20 ish I can see a shadow just underneath the aluminium bar that runs against the slab. It sort of bows down. Is this the bar bowing on the precious cut and if so do all of your slabs suffer from this with having such a long bar? Thanks
That's normal. For wood this wide and long, it will twist a bit anyway when drying, so that little bow is insignificant. During the finishing process it will all get straighten out, hence why the slabs are cut extra thick.
