262059 | John Ruth <johnrruth@h...> | 2017‑03‑24 | BRAND NEW Hollow & Round Irons Available from Corradi SpA in Italy |
GG's Got any hollow or round molding plane bodies which lack irons? http://www.corradishop.com/index.php?main_page=product_info&products_id=53 Copied & Pasted from their website: "GOLD Molding Plane Irons CORRADI GOLD molding plane irons are manufactured according to sizes, sections and tolerances of the British tradition. They’re made using ledeburitic tool steel which provides a high edge retention and reduced brittleness, thanks to a heat treatment done according to the highest quality standards reached by Corradi SpA’s century old manufacturing know-how. They’re hardened and tempered up to 61-62 HRc and, despite their high hardness, they well work even on heavy duty applications on very hard or abrasive wood without chipping or breaking. The blade is hardened to a length of 30 mm from the cutting edge which allows, if necessary, further multiple resharpening. The blade is ground on both sides with classical tapering (blade thickness 1/8” – tang thickness 1/16”) and lapped on the cutting side as to obtain an excellent cutting edge. The irons are packed in carton boxes each containing a pair of blades (concave and convex) already shaped and sharpened, ready to use, with individual plastic protecting cap, each blade wrapped in wax paper. Each blade has its own number and the brand “CORRADI GOLD” stamped on the cutting side. Radius of the arc the iron cuts equals the above width of the blade and it’s calculated for 55° bedded planes. All the irons are individually checked before packaging to avoid any defects and ensure the correct coupling of the concave iron with the convex one. Raw material, design and manufacturing of the irons are completely made in Italy." Look at that, would ya! They even understand the need to taper the irons! They understand the issue of bedding angle! (IIRC, 55 Degrees is "York Pitch") Pricey, yes, but think of how much work this would be to make it yourself, with the taper. And, if you have the original wedge, it was probably made to match a tapered iron, so buying these tapered irons avoids re-working the wedge, which, in turn, preserves collectability of the plane. Wow. Just "Wow!" John Ruth Metuchen, NJ |

as those are sold in pairs, the price isn't even that bad... if you're going to spend the time to build a set of hollows and rounds, that might be a nice way to kit them out. a quick search on "ledeburitic tool steel" implies a powdered steel, though, with a working quality not dissimilar to D2...which might be fine, but it might be a real pain in the hoompah to sharpen. best, bill felton, ca |

I get my H&R blades from Lie Nielson. They are of excellent quality and considerably less expensive than the Corradi blades. They are blanks, however and must be shaped to fit your plane. Ken Shepard |

John Ruth pointed to a company making molding plane irons: http://www.corradishop.com/index.php?main_page=product_info&products_id=53 whose transcribed description includes: "CORRADI GOLD molding plane irons are .... made using ledeburitic tool steel which provides a high edge retention and reduced brittleness, thanks to a heat treatment done according to the highest quality standards reached by Corradi SpA?s century old manufacturing know-how...." Does anyone know what ledeburitic tool steel" is? The term isn't in Wikipedia or Wiktionary. Tom Conroy |
