I wasn’t too impressed with the spindle that came with the stock Shapeoko 2, and I initially bought a Dremel 3000 to replace it. The Dremel had all the necessary power but … 1)I want the Dremel for other things, and 2)Its tapered body made it difficult to mount securely and square to the table. So I decided to add a trim router because of its pure cylindrical shape but that meant new mounts. Thanks to Matthew at Targ’s Workshop I had a starter file to modify to fit my needs.
