The couple times I’ve made scales I used this guy with my Dremel. I avoided having to buy a whole new tool and was able to use the dremel I was already using.

That’s what I use too. Dremel with a cut off wheel to cut out the scales, then switch to a sanding drum to shape. Lots of hand sanding. Then back to the dremel press for the holes.
