Ain't that funny we both read the same post and get two different versions of how he made that slot, after re-reading it, does sound like he did the dangerous plunge cut, if I used a chainsaw to make a saw holder, I would've cut through the side then add a piece of wood back on.I think he meant that he did a plunge cut with the chainsaw where he pushed the bar straight into the end of the 2x6 and let it carve it's own pocket.
