How To
I ran the 4V cordless rotary tool kit for this — light, easy to hold steady on a round jar. The 282-piece bit set had the small diamond tip I needed for a fine line.
The 200W corded tool with the flex shaft was the right call — the shaft takes the motor weight off my hand so I could hover one fret at a time. The 230-piece set had the fret polish cone.
The 8-inch caliper with the large LCD is what I use for wide boards — the big readout saves squinting across the bench. The wide-range caliper covers the long case pieces.
I used the 180W corded rotary tool with 153 accessories because corded holds speed under load — on a big flat face the bit doesn't slow and leave ripples. The 230-piece bit set had the flap wheel I finished with.
The stainless steel caliper lives in my tool roll because it's tough enough for the garage, and the rechargeable caliper is the one I grab when the light's bad.
