INSTALLATION
Place the shaper on a rigid foundation and level it lengthwise and crosswise. If the base does not touch evenly at all points on the bed, place shims where necessary. Fasten down with bolts.
Before operating the shaper, clean the rustproof coating from all bearing surfaces, such as ram table slide, column ways, etc.. with a cloth soaked in parafin, then wipe off with a dry clean cloth.
Before commencing to operate the machine, thoroughly lubricate all points shown on the lubricating chart on page 24.
CARE IN OPERATION
As with all machines, there is a certain amount of danger during operation, and although the Acorntools shaper is fitted with adequate safety guards, it may be as well to mention that the chief danger point is the tool feed control. It is sometimes necessary for the hand to be on this handle whilst the ram is in motion, and care should be excercised.
Always shut off the power supply before making any adjustments to the ram stroke, ram position, the cross feed or belts. The switch is conveniently placed for instant use.
Care must be taken to see that the tool head clears the column on the back stroke, and it is best to test this by operating the ram by hand through one complete stroke before turning on the power. To operate by hand, turn the four step pulley on the countershaft.
Be sure the direction of rotation is in accordance with the arrow on the large single-step counter-shaft pulley.
CONTROLS
The Acorntools Shaping Machine has four different stroke speeds. These are obtained by shifting the belt on the 4-step cone pulleys. Select the proper ram speed in feet per minute. See table of ram speeds on page 5.
The motor is controlled by an ON-OFF switch mounted in the main column. |
Starting and stopping the ram is controlled entirely by the ball handled lever. This lever should always be down when starting the motor. On the oposite end of the lever is a brake block which fits into the groove in a pulley on the countershaft. When the lever is let down, the tension on both belts is releived and the brake applied.
After stating the motor (with belts in the correct position) lift the ball handled lever until the ram starts to move. A little practice will enable the operator to move the ram along by inches to any point desired. When the operator becomes familiar with the movements, the machine can be set for work. The ram stroke and position should be such that the tool will clear the work by about 1/4" at the start end of the cut and about 1/8" at the finish end.
RAM POSITION
Make sure the ram will move its entire length of stroke and return without striking the tool head on the column. Ram position is adjusted by turning the shaft in the rear top of the ram with the crank handle after loosening the clamping handle located at the top. It is important that this handle is tightened securely before taking a cut, otherwise serious damage may result to the ram adjusting screw and its component parts.
RAM STROKE LENGTH
To adjust the stroke length, place the crank handle on the square-end shaft inside the large hand nut with the left hand and turn the crank handle half a turn to the right. This will free the shaft to adjust the length of stroke. (The ram must be at the extreme return end of the stroke.) Turn the crank handle and watch the pointer and scale at the side of the ram. The reading shows length of sroke directly in inches. Then hold the crank handle and trun the hand nut to the right until it stops. Lock by holding the hand nut and turning the crank handle to the left. Never strike the hand nut.
