Looks good.
Split it down? although walnut can be twisty and doesnt splitting.
Shame its so short. We've been running walnut through the woodmizer when we have opportunity. I think everything so far was flatsawn - which I think is silly but its not my walnut. Hopefully someone ripped some 2x 6 for benches as their boss had asked. If not I'll try to get er done when I'm back up there.
Rambling now.. back on subject
A cheaper 'alaskan' chainsaw would get some boards. The type that runs on a 2x4.
