mizoganna 溝鉋 | ||||||
KEY WORD : architecture / tools | ||||||
Also known as shakuriganna 决鉋. A plane used exclusively for making grooves in a doorsill or lintel. If the width of the groove is 7 bu 分, or approximately 21mm, then the plane and cutting blade also measures 7 bu. The plane is narrow, but its elevation from the sole, daizura 台面, is high enough to ensure that the cutting blade fits securely , and make the plane easier to hold. The wood shavings are ejected from a semi-circular opening in the side of the plane stock. Unlike the *anazukikanna 穴突鉋, which is also used to make grooves and has a special blade known as wakibari 脇針 for planing the sides of the groove, the mizoganna has no wakibari. Thus, a side-shaving plane wakiganna 脇鉋, is used to shave the sides of the groove. | ||||||
A) Opening for the ejection of shaving. B) Capping iron. C) Cutting blade. The cutting blade and capping iron are fitted into the sole. |
