My seven year old came out the other day while was doing a bit of clean up and asked if he could turn a pen. How does dad resist? This was not his first pen, but dad let him do a bit more of the turning on his own. Yep, we had to use 5 blanks to get 2 barrels, but that's ok. It is worth a bunch more blanks if he'll catch the bug. Anyway, he's pretty proud of his pen and dad's pretty proud of his boy.
