The Line Tool Model 128 will produce movements in the X-Y planes and a partial rotary movement. The travel of the slides is 1/2 inch. The movement of the rotary platen is plus or minus 10 degrees for a total of 20 degrees of travel. The rotary motion is not calibrated. The platen has a 1/2 inch diameter hole through it, which extends through the entire unit. The rotary platen has four #4-40 tapped holes in it.
The rotary motion is achieved by using a 40 pitch screw, which rotates the platen. One turn of the 40 pitch screw moves the platen 2-1/2 degrees.
For fastening, the lower slide is moved to one end of the travel to expose 2 counterbored holes and then moved to the other end of the travel to expose the other 2 counterbored holes. Model 128 weighs 2 pounds 7 ounces.
