Hi Harv. The main question I would have is how long has that log been laying around. A long time I hope. If not you'll start getting movement and shrinkage as soon as you cut it. Probably not too big a deal with blocks, but you will get checking, cracks that can open up pretty good in black walnut. I wouldn't be concerned with the child chewing on the black walnut as much as I would be concerned about chewing on whatever finish you put on them. I'm assuming you are planning on some kind of oil. I'd go with mineral oil or what they call salad bowl finish (also an oil). By the way, black walnut tastes really bad. /forums/images/graemlins/tongue.gif
The only thing that comes to mind about your pin and holes idea is swelling from humidity or even the possibility of getting wet from rain or some other source. Speaking of moisture, if it were me, I would definitely raise the grain on every surface of every block. Just dampen them with water, let them dry and then sand. They will look nicer in the first place and they will definitely wear better. Nothing shoots a nicely started "patina" than a little moisture to raise the grain.
Overall, your ideas have appeal. I might also suggest getting some of the log slabbed out thicker than 2'. Good luck if you decide to proceed.
