I have and use an LV bu jack, jointer and smoother. I use them almost exclusively. I have cambered an iron and mostly use it in the jack but I can use it in the smoother if I want a shorter plane or in the jointer if I choose to. The cambered iron looks a bit strange when compared to a BD plane. It works fine however. I can’t remember the exact angle I put on it. It was a 25* iron and I think I went to about 30*. It’s a PMV 11 iron as a jack it isn’t sharpened often. I do have 2 Bailey #5’s I could use but prefer the LV. It’s not for everyone. I prefer the center of effort, as described well by Derek Cohen, because of severe back problems I have to deal with. If you have a good grinder it’s no big deal to camber an iron.
