I was distracted and pulled a newby move. Glued up another trilam last night, shut off the oven at midnight. Pulled it out and started the clean-up and prep for grip glue up. My son, who is almost 9, says "dad, I think you goofed". I didn't see what he ment until he pointed out that what was meant to be boo/walnut/yew, in fact is boo/yew/walnut. Bloody hell! Guess I'll see what happens. Got more supplies to do it right yet. Adventures I guess.
