Hollows and Rounds
Hollows and rounds are wooden molding planes used to create a variety of curved edge and surface treatments in architectural and furniture projects. Hollows and rounds typically cut an arc that is 1/6th or 60 degrees of a circle. A hollow has a concave surface, while a round has a convex surface.
Hollows and rounds are often found in numbered sizes, from No. 2 up to No. 16, with the majority of sizes representing 1/16th of an inch. Sizes larger than 3/4 inch often are sized in larger increments. A half-set of hollows and rounds consist of the even-numbered sizes in the range. If these are from varied makers, the set is said to be a harlequin set.
