Reflatten a Stanley Transitional Plane?

Either way using a plane or jointer will possibly make the throat area wider on your plane . This should be fine unless a great amount of wood has to be removed.

-- Jim from Heirloom Woodshop Southern Oregon

If it was me I would probably opt for the sand paper, like you would do with a metal plane.

-- A hammer dangling from a wall will bang and sound like work when the wind blows the right way.

Use Sandpaper…

However, be aware that you’ll also be widening the mouth of the plane as you take off material. You might have to make a mouth piece to close up the gap…

If your looking for information on how to close the gap check out the following book.

Just put some sandpaper on a flat surface and go to town on it by running it back and forth till it’s flat. The throat can always be cut out and made smaller by inlaying a new piece of wood and making the opening the size you want. I saw a tutorial on this process but I can’t remember where I saw it.

Some more info here on the process.

i would have to agree that sand paper would be the best way to go, but do you really plan on using this plane, if not it may be nicer to give it a good home on the shelf. just my 2 cents. have fun.

Another way to do it is using a jointer plane upside down in a bench vice….

Retire the old brute, give it a nice wax job and a place of honor in the shop and admire it (I’ve got a #32 doing just that duty). Ya got a jointer right? It cost alot of money right? Its accurate right? Use that.
