This tool is used for transferring the contours of one shape onto another. This is what makes it an ideal log scribe, but it also makes it an excellent carpenter's scribe. It can translate that not-so-straight 100 year old wall profile onto a cabinet panel, letting you get a perfect match. The photographs show the very tight fits that are standard when using it as a transfer scribe.
With a maximum capacity of 12", it is calibrated so that any opening can be used once the double bubbles are set for a given pin and pencil projection. The rotatable double-level post can be adjusted and locked in any position on either axis.
The pointed end of the steel pin is for compass work - the blunt curved end is non-marring for transfer scribing. Other components are non-corroding brass and zinc aluminium alloy. Usable with any standard pencil, it comes with a purple indelible pencil that marks well with light pressure.
