Reply To: Squaring bevel on tapered plane iron

If it was me, I’d start by assembling the blade in to the plane again, so that it looks central (same gap on either side at the bottom near the mouth, then advance the blade through the mouth until the full width is projecting out above the sole. Then have a look at how the lateral adjust affects the projection. If you can get the blade edge parallel across the sole of the plane this way, then back the blade out again, and try it out. If it takes nice wide shavings, then great.
If you can’t get the blade edge parallel, then mark a line across the blade a little bit below the lowest corner and then disassemble the blade and start to sharpen away again until you are closer to parallel to the line. Then retest the plane function again. That should get you where you need to be.
