Mike recently stopped in at our local historical salvage yard and picked up some 200 year old white pine boards for a few floor repairs in the main house. They had been subfloor or sheathing boards in their previous life, so were rough finished. And as such, they are not as uniformly high quality as original floor boards.
Jack Crane, the craftsman who built our front entry and our new (old) windows invited Mike to his workshop to run the boards through the planer (as he was getting ready to change his cutters in the planer and so was not worried about damage). The result is quite dramatic.
Here is a side by side comparison before and after planing. Some of the boards turned out in better shape than others, but we'll be able to piece together the repairs with the aged wood. This will be our best chance at reasonably matching the similarly aged boards that are in the house already.
Now the replacement boards are ready to be installed.
