Step 12: Glue spline in place
Using more of the same epoxy, glue the spline into position on top of the magnets. This will hold all the magnets in position forever.
Apply clamps and let the epoxy set. I used masking tape to protect my clamp heads so that they wouldn't become epoxied in place from any squeeze out that might occur.
Once the epoxy has set, remove the clamps and sand off any glue marks.
