Transitional planes are the pariahs of the woodworking world. The tool collectors don’t want them. Patrick Leach burns them in a funeral pyre. I’ve had a few over the years I got for a song and kept in the shop mostly for decoration.
As I got more into timber framing and working with green timbers it dawned on me that these transitional planes — at least in the jack and jointer sizes might be useful for cleaning up timbers. The large wooden sole doesn’t rust the way a metal plane would when exposed to wet wood for long periods of time and you have a more or less modern Bailey style mechanism. The one annoying thing about the mechanism on a transitional plane is the blade advancement wheel spins the opposite way a metal plane works, but after a few minutes you get used to it.
For some timber frames I need to clean up and remove all the large circular saw or bandsaw marks. In a workshop or outbuilding being fresh from the mill is fine, but in a house all those rough surfaces can be a dust magnet or source of splinters.
On my jack plane I’ve ground a camber appropriate to a jack plane and take a reasonably heavy shaving. The work goes fast and I admit its fun to make a 25′ foot long shaving on some of the largest timbers.
At first I felt bad about using a plane from the 1870s for this sort of work, but if properly maintained it will have a surprisingly long life and I’d rather see this plane get used as opposed to being in a pyre or on a shelf.
At the end of the day I make sure to remove the iron and wipe it down with oil so it does not rust and I’ll usually give the sole a little more wax.
I can usually find these planes in surprisingly good shape for $10-35. If you’re willing to take one with more rust on the mechanism or a replacement sole you can likely get it for even less or even free from some dealers if you buy a few other items. The next time you are at a tool swap you may want to take a second look at a transitional plane and score yourself a good deal on a solid workhorse for your own timber framing or green woodworking projects.
