Hi David…
I know what you’re talking about. I use that method sometimes. I’ll use my skill saw to free the outside runners. This leaves me with boards that are about 3" shorter and still attached to the middle runner. Now, if I’m very careful, I can rock each board and get enough gap for the recip or the osolater saw. The point is, when they build the pallets, the blunt, spiral nails will split the wood on the outer ends because there is only about 3/4" of wood to the end. However, the nails in the middle runner have enough meat around them to avoid splits. Hope this makes sense.
