This badger beds at 20, which is what i'll try next, but I am going to modify the abutment on the right a little bit so that the abutment is closer to 90 degrees. That won't be hard to do on the wedge.
28 degrees is pretty extreme. I really should've done what I just described to the abutment, left it around 15 degrees instead of 28.
This was the least nice, or second least nice piece of wood out of my pile so I don't mind too much. I just wanted to try this style of panel raiser because it would look from above like a normal bench plane. If I add lean to the double iron like one would do on a badger plane and go with 20 degrees, and basically do what the donor plane had (it has held up fine, long enough to have erosion around the mouth), I can use the iron as is and do a job similar to this one and just have an extra 3/8th of width, or just literally make another badger plane and attach an adjustable fence.
I favored this design because it allows a wedged nicker, but there would've been a lot more to favor with a double iron that would've bedded with less skew. As you're implying, not much is needed to get a decent cross grain cut.
