Mortise Gauge Self Locking

<p>Firstly, I completely stole the locking pin idea from a Paul Sellers video on YT. He made his tool out of timber but I thought I'd see if it would work from a 3d printer and it works really well. Full credit for the idea goes to Paul, all I did was draw it up. Go check out his video to see how the locking mechanism works.</p><figure class="media"><oembed url="https://www.youtube.com/watch?v=2P4PhF-poJY"></oembed></figure><p>Some tolerance has been built in but actual fitment will depend on your printer and settings. For speed, I printed mine at 0.3 layer height with a 0.6 line width on a 0.4 nozzle so not the greatest quality settings. The locking pin was a little tight but after a light sand and some paste wax it was good to go.&nbsp;</p><p>Clip the head off a nail, jam it in a drill and sharpen the end to a point. Glue that sucker in the hole at the end of the shaft. Rinse and repeat and you're all set.</p><p>Optional: Push the locking pin cap to the end after it's all installed and working for an even cohesive look. Mine didn't need glue, they were a nice tight fit. YMMV.&nbsp;</p><p>Check out my other files for a single pin marking gauge using the same locking pin idea, as seen in the photo.&nbsp;</p>
