Tongue and groove

Now the cabinet carcass is mostly finished, I've been accumulating piles of dimensioned lumber for the door, the drawers and the back. That's just boring stuff of course, but today I had a nice little job. Adding tongue and groove to the pine boards for the back. I had some old pine shelfs with an almost ideal dimension. This old pine is lovely stuff, very tight grain, and a nice butter color.

The tongue and groove was a great excuse to show off my set of match planes from Ary den Hengst, a planemaker working in Rotterdam in the 18th century. The planes are made for thin boards, 8 to 9 mm thick, so ideal for a job like this. They still work perfectly well.
