Here are some pictures of a cast iron shifter repair.  The shifter fits in the headstock of a 
round dial Monarch 10EE.  The shifter is controlled by the Thread Left/Feed/Thread 
Right selector knob on the front of the headstock.  This was a finding in my restoration of 
a 1942 basket case 10EE I am attempting to restore.

The casting was repaired by burying #10-24 socket head screws inside the casting arms.  
I counterbored with a 5/16” endmill for the socket head, drilled the base 13/64” for 
clearance, and then the #25 drill into the end piece of the arm before tapping.  A spotting 
drill was used to establish the drill center in each case.

As much as I hate to say it, this was all basically done by calibrated eyeball and a magic 
marker…fine point sharpie.  I had no way to fixture both the parts as I drilled them, 
hence the clearance hole in the base part of the casting.

We shall see how it works in actual operation.
