Re: Do you profile your cap irons?

The plane is capable of putting the cap iron below the sole, though it will likely cause feeding problems.

The reality is, you'll never push the plane with the cap iron projected below the sole, or even at the sole itself.

Next time you're in the shop with a fore plane, set the cap iron at 5 thousandths and take a 7 thousandth thick shaving (which will represent about 5 thousandths of cut depth). That will be the cap iron set equal with the sole.

The cap iron doesn't need to match anything but the sole of the plane because you'll never use the plane with the cap iron below the sole, regardless of whether or not it can physically be moved to a position like that when it's not cutting.

That's precisely why matching a cap iron (or clipping the corners, or whatever you'd like to call it) isn't necessary. There is, perhaps, a chance that nicholson and others liked just having the corners clipped because it would lessen the chance of a feeding problem in a plane that has a setup problem. But in terms of tearout reduction of functionality, it doesn't matter how much the cap iron overlaps the corners of a cambered iron because you'll never be able to push the plane with the cap iron even with the sole. You might, perhaps, be able to do it with a 2 thousandth shaving, but that's not going to happen on an iron with much radius.

Give it a try.

Kato and Kawai is a bad illustration of what can be done hand planing because it doesn't give you an optimal set for hand tool work, and because the power of the machine results in things being shown that are not done with hand tools. That's OK for the video, though, because it was intended to help with the development of the super surfacer.
