ppt of milling attachment of lathe
BY CLEVERLY stacking cold-rolled flat stock together, T-slots and slide for this lathe milling attachment are made without costly machinery. In fact, only two tools, a drill press and lathe, are needed to make the attachment.
Shown mounted on the cross slide of a lathe ,the attachment features a swivel baseand tilting slide which has T-slots for clampingthe work securely in place. Although this attachment was made for a 7-in. Atlas lathe, the
overall dimensions could be increased 25% for use with a 9 or 10-in lathe. Start by cutting the stock size cold-rolled flat stock for T-slot pieces A, B, C and D to 3-in. lengths. Then lay out and drill the #21 holes. Pieces A and B, and C and D can be clamped together when drilling so that they will line up properly when assembling later. Next,
hacksaw the slide plate E to shape and trim up the cut edges with a file. Lay out and scribe lines on the slide plate for locating pieces B and D. Be sure these lines are square with the sides of the slide plate. Clamp the B and D
pieces to the slide plate and drill the 12 #21 holes. Then open the holes with a #9 drill and countersink the holes on the back of the slide plate to sink 10-32 fh screws just below the surface. Tap the #21 holes in pieces A and C
with 10-32 NF threads.
