Universal Indicating Attachments

Precision set-ups with speed and accuracy demanded by modern machine work, is now possible by using on or another of these interchangeable attachments. With this wiggler, you can indicate from toolmakers buttons or holes, ground blocks, the side of round 
How to use the BALL SHAFT

PRECISION BALL the ball applied to surfaces is hardened and ground to an exact diameter of .25".  In the making measurements, taking half its diameter, or .125", gives a precise center.

Indicating from ground or machined surfaces, gauge blocks, etc.

The ball shaft is used for set-ups where locations are to be made from ground or machined surfaces, gauge blocks, or sides of round work. This attachment is the one you will use most frequently, as you will find that it simplifies many difficult indicatin
Bent shaft holds ALL INDICATORS

This indicator shaft is used with an indicator to locate from tool-

STEP 1

Insert the large ball of attachment into the spring chuck. With the spindle turning, make the ball run true by holding any blunt object against it. Apply a thin coating of layout blue on the ball and feed the work up to it until the blue is barley wiped.

STEP 2

Lower the table and move it .125" (half the diameter of the ball) to bring the reference surface (S) directly under the spindle center. By using the micrometer collar on the lead screw, any desired distance from the original position can then be located.

Shafts snap into the Spring Chuck

Locating TRUE vertical center lines of round bars

STEP 1 Apply layout blue to the upper surface of the work. Then, with the ball shaft running true raise the table gradually wile moving it slightly back and forth until the blue is barely wiped by the precision ball. This locates the height of the upper s
STEP 2 Next, with spindle running, move the work away form the spindle and raise it a distance of one-half the known diameter of the work plus .125" (one-half the diameter of the precision ball). This places the centerline of the ball and the work in the 
STEP 3 Now you can locate the spindle center precisely where the vertical center line of the work by lowering the table and moving it toward the spindle one-half the diameter of the work plus .125" (one-half the diameter of the precision ball.)

84-P Needle Point

The "NEEDLE-POINT" shaft

The sharp, slender point is used to find center and for truing to layout lines. It insures accuracy and is readily replaceable.

The "Needle-Point" is held in a rigid friction grind. To replace with new point, merely use pliers. If grinding is needed - the shaft retains its original length. It is the same precision used on other "Needle Point" tools.
