Huge round molding plane
I've been playing around with some mujingfang rosewood hollows and rounds lately, and have been having a lot of fun. One thing that I realized though, is that I can't cut very large coves. Even with the largest size they offer, I'm only getting a 1 1/4 inch plane. I could cut a cove that's a fair bit wider than that, but I've seen some huge cove moldings that I don't think I could even approach.
So I had a thought - what would happen if bought a cheap old wooden bodied jack plane, shaped the sole into a round, and then ground the iron to match it?
I feel like this could get me a 2" wide round plane for pretty cheap. Only thing I can't picture is what the mouth of the plane would look like after this operation. I may have to close up the mouth somehow in order to have a usable plane. Definitely couldn't make the sweep of too small a radius, or I'd risk removing too much of the material that holds the blade in place, I'd think. But a fairly large radius wouldn't remove the much material, and would allow me to make quite a large cove in thinner stock.
Right? Anyone ever tried something like this?
