GEARING. 21 It is evident that, as the teeth project beyond the pitch-cone, both it and the normal cone must beenlarged beyond the original dimensions. Thus FP must be extended till FD is equal to the ex-treme radius of the developed tooth, which is projected back upon it, and the blank for the wheelwill consist of a frustum of the cone D V H, joined to a frustum of the normal cone 1) FH. Thebottom of the space in the development is also projected back upon FP at F, and the top and bottomof the tooth will be bounded in the secti
