This insert lets you align the center of your spindle with markings on your workpiece. You don't even have to remove the spindle! It's super easy & quick to make. Fingers are reasonably far away but you can plug out the spindle for the time of alignment if you don't feel comfortable.

3mm acrylic
20 cm of string (e.g. dental floss)
SO
3mm bit
V bit
Secure the piece with double-sided tape. The circle should have tape right underneath. There are 4 things to cut - start from the center. 1. Using the V bit only slightly mark the center point, e.g. 0,5mm. 2. + 3. Change to a 3mm bit. These are the holes for the string. 4. Outside cut using 3mm. Note: When attaching the string be sure to attach it in a way that the center point is on the bottom. The diameter works well for 3mm acrylic but it might have to be decreased if a thicker material is used.
