    I recently picked up a vintage Stanley router plane in great shape with two irons at a garage sale. The problem is, someone did a poor job of sharpening the irons at some point (the top bevel isn't even, and there appears to be a secondary bevel on the cutting edges), and I would like to fix that and get the plane usable again. Does anyone here have any experience doing this that could provide some input/tips on doing this?

    Sharpen them as you would a chisel. Shouldn't take too long with a stone. joe

    Set your stone on a block of wood so that the 90* “tail” on the iron clears the bench and push the bevel sideways across the edge of the stone. Place your index finger on top of the tip of the iron to keep the bevel flat against the stone and square to the edge of the bevel. Use an appropriate honing fluid.

    I wouldn't worry about it being a little out of square.

    This is where it pays to learn how to sharpen freehand, if you don't already. I'd just take it to a coarse diamond or India stone and grind it down to the geometry I want, putting pressure on any high spots.

    As has been stated above, it's like sharpening a chisel. If need be, you might need to refine the angle of the iron at a grinder - remember to do it slow, cool in water often! Once the initial bevel is set, using stones is not hard. Here are two folks who might help...

    If you want the iron OCD sharp and done, send it to me and I will do it. I am a Carpenter and I have the Tormek T7 sharpening system and you will be able to see yourself in the edge.

    Thank you for all the suggestions. I have done chisels before, but I try not to let them get too bad before touching them up. @Sawdustdave I will look at the videos, and give it a shot this week. @roadwarrior, I will keep that in mind if my hand sharpening doesn't go as planned.

    I'd recommend just getting a coarse diamond stone. 150-300 grit. It'll make tool restoration a whole lot easier. I've ground 1/8" (several millimeters) off of chisels with just my #150 diamond stone, and even made a few tools from (unsoftened) files for metal working. It's superbly useful to have around, and a lot smaller, safer, and less noisy than a grinder or belt sander.

    I will have to look into that. I usually just use sand paper on a granite block

    I managed to get them cleaned up acceptably last night. They were pretty far off, so I ended up using a disk sander, and going real slow and cooling them frequently. They still need a little work on a stone, but they at least cut and the edges are straight.
