Hollow and round planes are hot thanks to the massive efforts set into the Musings from Big Pink blog. Hollow and rounds complete the possibilities offered by my Stanley 13-050 Combination Plane, so it is interesting to look further into the possibilities of these planes.
With my Stanley 13-050 I have already a (skated) rabbet plane, and besides that I also have unfenced wooden rabbets.
The next step is cleaning and sharpening. Matt Bickford demonstrates handheld sharpening with flat oilstones, two slipstones for hollows and some leather. A more thorough approach would be viewing the Sharpening Profiled Hand Tools DVD by long time expert Larry Williams.
And planing? Using wooden profile planes is fun, more than a skated Stanley 050 or a router. Being precise with them is probably a different story.
