Prepare necessary equipment and tools

Milling machine / Drill press - Make sure it's clean when you start the job and that the pitches have been calibrated.

Drill bits - Make sure they have been sharpened recently.

Ruler - Span ruler that is accurate to at least 1/16" - Having a post to secure it can be handy.

Bevel sander - We recommend putting on a new sanding disc for every ball you drill for consistency.

Grease pencils / pinpoint scriber - For drawing the reference lines on the ball. If you want to use a scriber, make sure it's ok with the customer.

Instant cure glue - For installing finger inserts, thumb inserts, thumb slugs and interchangeable thumbs.
