I created this unique combination triangle for entering into a tool making contest hosted by WoodCentral. I designed it accomplish three tasks that are common in my shop including accurate 45 and 90 degree angles, a ruler for measurements, and a marking knife for getting a precise line. The triangle is wide enough at 3/4” to stand up by itself so that it doesn’t need a third hand. The back of the triangle contains an elongated slot for storing the marking knife to protect the tip when not in use. A magnet is inset in the slot to keep the blade firmly in place. The knife was made from wenge and a polished reciprocating saw blade. Thin wenge wafers cover four ¾” magnets that are inset on the perpendicular sides of the triangle. The magnets allow the ruler to be interchanged as needed.

The ruler is quarter-sawn maple with macassar ebony inlays for each of the 113 individual markings at 1/16” intervals across the rulers length. A thin strip of the reciprocating saw blade is inlayed into the back of the ruler so that it can attach to the magnets in the triangle. The ruler was designed to be detachable so that it could swapped between two positions on the triangle or used independently.

All three corners of the triangle have paduak dowels that were specially turned on my lathe to provide added joint strength besides visual interest. Strips of 1/4” paduak were inlayed into the interior triangle edges for additional appeal.

All pieces are finished with a few coats of shellac followed up with spar varnish to provide UV protection and hopefully preserve the colors.

This is a wonderful project. Not only is it functional and useful but it looks good as well. I am sure that it gave you a lot of satisfaction in entering this in the contest.

Well done.

Beautiful. Might I suggest adding a hook to one end of the rule? You could then use one end to lay out inside and the hook end for outside mark out.
