Glass Cutter: Monce's Hardened Steel Wheel
S. G. Monce's glass cutter (US 91,150, 1869): a small hardened steel wheel, bevelled from both sides to a sharp edge, turning on its own journals in a riveted frame on a handle. Drawn across the glass under pressure it rolls and scores a fine line like a diamond's, for a tenth of a diamond's cost, and it needs less skill. It is the wheel cutter still used today.
The patent gives no sizes, steel grade or hardening method. The picture: the patent's drawing sheet.

Turn the steel wheel
Turn the steel wheel
Turn a steel roller smooth and round, with a solid journal (d) at each end. Its sides (a) run parallel for a short way, then bevel toward each other to meet about midway in the cutting edge (D). Each bevel (c) stands about 45° to the axis, so the two faces are near right angles, or a very little more obtuse. Ours: a hardenable carbon steel and the lathe.

Make the two-piece frame
Make the two-piece frame
Make the frame (B) in two halves. Near one end drill a bearing in each half for the journals. Keep each journal a little shorter than the thickness of the frame's sides (e), so a straightedge laid against the sides never touches the journal ends. Ours: steel strip, drill and file.

Score and break glass
Score and break glass
Draw the cutter quickly across the glass, pressing as you go, so the wheel rolls. It leaves a fine line like a diamond's. Guide it along a straightedge; the frame's sides ride on the edge. Break the glass along the line.
