Friend Robert called me a couple days ago. His planer was broken, and parts were on backorder so he needed to use mine to plane a dozen pieces of walnut for a Christmas project he's working on.
Anyway, he brought it over, and we ran it through my 15" planer - just took a few minutes, since it only took a couple passes per piece.
As 'payment', sorta, he brought me a really nice piece of rough cut maple. It was 1½" thick, 14" wide, and a bit over 10 feet in length, but had a slight twist pretty much right in the middle. To make it usable/planable, I cut it into two five footers, and ran it through the planer. Since it had been sawed with on a circular mill, it was pretty rough, and I lost not quite a quarter inch in smoothing it out, but it came out great! Take a look:
