Mistake!

I did get the pulping done but washing down the pressing boards with a caustic solution (125g per 5 litre) wasn't a good idea... I usually use a bleach solution, but as the boards (well most of 'em) were newly cut I thought a stronger agent would be better. What I hadn't reckoned for was the brown residue that would issue from the caustic soaked boards! May just be tannin from the hardwood, (I've only used beech- faced ply before...), but to be quite sure I've rinsed and rewashed and rinsed again until the rinse water stayed clear...
So at 9.15 last night I gave up on the pressing. At least all is ready for tonight...
something else could go wrong yet...
