Old fence rails shaved down to be legs for the trestle table.
Twenty six passes gives a reasonably flat surface, so I flip it over to work on the opposing side. The peak has been lopped off with a hatchet.
Many passes with the plane gets that surface reasonable. Now I'm debating if I want to try to get two legs out of this..
It's three inches wide which would make it One and a half, minus the kerf. The holes in the too pieces are one and a quarter, so that doesn't leave much margin for cleaning up the sawn face. And it wouldn't leave much for the legs to be rectangular...
