Made a whole fighter wing of marking gauges when constructing the ones for the tool swap. The design is loosely based on David Barron's mini marking gauge. I did email David before using the design and he graciously gave permission to do so. The thing I like most is that it is very compact (about 3 inches each dimension) and fits easily in one hand. Woods used included curly bubinga, bloodwood, macacauba, pear and mineral streaked silver maple. The pear and maple were salvaged from my smoking wood pile and most of the rest was scrap from other projects.
The second picture is the two that were sent to shampeon as part of the swap. You can see that there are two different blade designs. One is made from a heavy bimetal recip blade. The harder cobalt steel is still at the tip, so it should stay sharp for a long time—if not, it can be resharpened several times. The other blade is ground from a pipe tubing cutter replacement wheel and has four cutting points so when one gets dull, the blade can be rotated to a sharp one.
The last pics are close-ups of the gauges. The two with maple fences and the brass wear strips in pic 3 were test runs for the swap design. Those two, as well as the maple and bubinga one in the last photo were kept in my shop for use—they either had design flaws or an error in building so that I wouldn’t feel right giving them to someone else. The remaining gauges have been or are going to be given out as thank you gifts to woodworkers that do demonstrations in the stores where I work.
