Chuck for Lathe.

The chuck shown will be handy for holding nuts to face off, or for that matter, a great variety of pieces to be turned. A can be made of cast iron with projection B to screw on spindle, or it can be made of wagon tire steel 3/8 x2 1/2" and a hexegon nut, B, welded on and afterward topped out to fit on lathe spindle. The sliding pieces, C, fit over edge of A, which is beveled and has a set screw. D, in one end to clamp to plate. The screws,

E, (of which there should be several lengths) give the grip which holds the piece to be turned. It is advised to use screws E as short as possible, so that they will project no further than necessary, as they are great "knuckle dusters."

A chuck of this kind has been in use several years and has been found very handy on many occasions, and is well worth the time consumed in making.

Chucks Made From Pipe Reducers.

These chucks are very handy, as a piece of wood can be screwed into the socket at A and turned to hold any special piece to be turned. The part C is for f" pipe size and should have a piece of round iron, B screwed in tight to be held in a self-centering chuck. All chucks should have same size at C, but the opening at A should be for 1 1/2, 2, 2 1/2 and 3" pipe size.

Drill Rest for Tail Spindle.

The holder A fits on a blank centre by hole B. Plate "C" is made with holes D of different sizes in this plate, as follows: 1/8, 1/4, 3/8, 1/2, 7/8, and 3/4". The plate is held by a spring pin, E, which enters a small hole in back of plate directly over hole opposite end of tail spindle. The construction of the plate is so plain that it hardly needs any description. This size is suitable for lathes from 6 to 9" swing. The entire plate is made of cast iron. Care should be used in forcing the holder A on the blank centre at B, as it is held by friction.
