Quarter Pounding...

Well, after I completed all the wheels and axles, it was time to quarter them.  I made two jigs.  The jig to quarter the axles came from J. Nelson's "So you want to build a ...".  I stamped a "1" on top of one side, rotated it 90 degrees then flipped it over end over end and stamped a "2" on the top. This would eliminate mistakes when flipping it around when machining.  It looked like this.

 

The jig for the drivers was made out of a 1/4" plate steel with a pin (broached) the size of the axle welded to the center.  I then securely clamped the jig to the milling table.  After carefully centering it, I moved the mill table/jig exactly 2" (half the stroke).  I then mounted the driver and drilled the eccentric hole using increasingly larger drills.  Once I got close to the size needed, I milled it with the special end mill/cutter shown.  This setup insured that all the drivers were machined the same.
