Mounting Hardware on Panels, Chassis, etc.
It is almost inevitable that when you measure and drill holes in surfaces to mount motors etc., you never get things perfect.
The following procedure should give great results to get holes in the correct position.
-
Measure the hole locations needed for your motor, transfer these to a graph paper template
-
Use this template to make a rough pattern on a piece of scrap material
-
Make the holes in this pattern oversized with the motor still being able to be positioned as needed
-
Put the best fitting washers over motor mounting setscrews
-
Glue these washers in place with CA glue, use accelerator
-
Place the pattern on the final surface which the motor is to be mounted
-
Use transfer punches to mark the perfect centers of the washers
-
Drill holes in the final mounting surface
-
Attach the motor with washer and nuts
