📐 Spring Divider Caliper Compass: Achieving Precision and Flatness Review

They seem solid and well made, but you can't use the turning screw for fine adjustment as the bead hangs on the screw part. So you unscrew it and the calipers don't move with the pivot bolt until you pull it in and then lock it.

This is exactly what I needed to send the exact measurements. The needles are long and sharp, so find a thick block of foam to rest between uses. The adjustment screw has a very fine pitch, which is great for fine work but tedious when you want to open or close the dividers quickly.
