release the support. When operating the drill press, ensure that the head support collar lock handle is tight at all times. As you face the drill press, the tilting table lock handle is located at the right-rear side of the tilting table  bracket.  The  lockpin  secures  the  table  at  a horizontal or 45° angle. This allows you to move the table  to  the  side,  out  of  the  way  for  long  pieces  of wood. The table support collar (8) allows you to raise or lower the table. Turn the tilting table lock handle counterclockwise to release the tilting table bracket so it can be moved up and down or around the bench column. Lock the tilting table assembly at the desired height  by  turning  the  lock  handle  clockwise.  When operating  the  drill  press,  ensure  that  the  tilting  table lock handle is tight at all times. The  adjustable  locknut  (14)  is  located  on  the depth gauge rod (17). The purpose of the adjustable locknut  is  to  regulate  depth  drilling.  Turn  the adjustable   locknut   clockwise   to   decrease   the downward travel of the spindle. The locknut must be secured against the depth pointer (13) when operating the drill press. The depth of the hole is shown on the depth  scale  (15). Observe  the  following  safety  precautions  when operating a drill press: Make  sure  that  the  drill  is  properly  secured  in the  chuck  (12)  and  that  the  chuck  key  (9)  is removed before starting the drill press. Make sure your material is properly secured. Operate the feed handle with a slow, steady pressure to make sure you don’t break the drill bit or cause the V-belt to slip. Make sure all locking handles are tight and that the V-belt is not slipping. Make  sure  the  electric  cord  is  securely connected  and  in  good  shape. Make  sure  you  are  not  wearing  hanging  or loose clothing. Listen  for  any  sounds  that  may  be trouble. After  you  have  finished  operating press, make sure the area is clean. signs  of the drill Woodworking  Lathe The woodworking lathe is, without question, the oldest  of  all  woodworking  machines. In its early form,  it  consisted  of  two  holding  centers  with  the suspended stock being rotated by an endless rope belt. It was operated by having one person pull on the rope hand  over  hand  while  the  cutting  was  done  by  a second person holding crude hand lathe tools on an improvised  beam  rest. The actual operations of woodturning performed on a modern lathe are still done to a great degree with woodturner’s  hand  tools.  However,  machine  lathe work  is  coming  more  and  more  into  use  with  the introduction  of  newly  designed  lathes  for  that purpose. The  lathe  is  used  in  turning  or  shaping  round drums,  disks,  and  any  object  that  requires  a  true diameter.  The  size  of  a  lathe  is  determined  by  the maximum diameter of the work it can swing over its bed. There are various sizes and types of wood lathes, ranging  from  very  small  sizes  for  delicate  work  to large surface or bull lathes that can swing jobs 15 feet in  diameter. Figure 3-5 illustrates a type of lathe that you may find in your shop. It is made in three sizes to swing 16-, 20-, and 24-inch diameter stock. The lathe has four major parts: bed, headstock, tailstock, and tool rest. The lathe shown in figure 3-5 has an iron bed and comes in assorted lengths. The bed is a broad, flat surface that supports the other parts of the machine. The headstock is mounted on the left end of the lathe  bed.  All  power  for  the  lathe  is  transmitted through the headstock. It has a fully enclosed motor that  gives  variable  spindle  speed.  The  spindle  is threaded at the front end to receive the faceplates. A faceplate attachment to the motor spindle is furnished to hold or mount small jobs having large diameters. There is also a flange on the rear end of the spindle to receive large faceplates, which are held securely by four stud bolts. The tailstock is located on the right end of the lathe and is movable along the length of the bed. It supports one end of the work while the other end is being turned by the headstock spur. The tail center can be removed from the stock by simply backing the screw. The  shank  is  tapered  to  center  the  point automatically. 3-6
