How does that work when you use a cast head, do you simply file it up the way it comes or does a person have to anneal it and then harden/temper when your done? I like those chests you make. Where do you get those locks, are they the type that when you close the lid it automatically locks? If you lived closer to me I would give you all the pine you ever needed for chests for the rest of your life, I have piles and piles of really wide clear 5/4 white pine. Honestly, I don't know what I will ever do with the stuff. Regards, TC
