Y axis stepper motor mount
I have been glassing a lot lately, and the opportunity to work on my “back burner” project once again felt like a breath of fresh air. So, I decided to put away the fiberglass for the day in favor of machining aluminum.
Today I made another electric stepper motor mount. The motor will drive the Y axis of the mill once the CNC conversion is completed. The process looked a lot like making the X axis mount, so I’ll let the pictures do the talking.

| Using an edge finder to locate the origin (X=0, Y=0) of our coordinates system |

| Using the X and Y readouts to locate and center-drill features on the plate |
 |
| Drilling all the holes out to 1/4" (6.35 mm) |
 |
| Counterboring the plate-to-mill mounting holes to 3/8" (9.52 mm) |
 |
| Enlarging the center hole to 3/4" (19.05 mm) |
 |
| Countersinking the plate-to-standoffs holes on the back side of the Y plate |
