FILENAMES: tooling-1.jpg tooling-2.jpg DESCRIPTION: These are pictures of an unknown type of turret lathe tool posted by Tim Leech . Tim provided the following description: ========================================================================= The item depicted came with a small lathe capstan (turret) assembly I bought recently; I don't know a lot about turret tooling, and am mystified by this one. It consists of a backplate on a 5/8 inch shank, with about 3/8 inch bore. There is an arm, pivoted about the pin at the left of the pictures. This is spring loaded away from the centre, by a small coil spring within the backplate, with a small pin through the arm bearing on the spring. Screw 'A' adjusts the travel on the spring. 'B' is a hole in the backplate, which can be used to insert a small rod to hold the arm in its closest position to the centre. In this position (shown in the labelled photo) the *lower* face of the toolholder is approximately radial to the centre. 'C' is a screw running through to the centre hole, presumably to secure a bushing. 'D' is the securing screw for whatever tool this is designed to carry. Screw 'E' is threaded right through the arm, with a locking nut at the other end. I can see no function for this at all, unless there is something missing. 'F' I would guess to be a tool depth adjusting screw. The other photo shows the arm at the outer end of its travel. The arm is stamped 'B&S Mfg.Co., Prov. R.I. U.S.A. No 00S' My best guess is that the working position is with the arm held down using hole 'B', this being released for passing back along the workpiece. I can't see, with the range of tool positions, how it could be used for conventional turning operations.
