This is the marking gauge I made for the LJ Marking Gauge Tool Swap for fellow LJ JayT. This is my first time in an LJ Tool Swap, so my gauge is functional, but not as polished as the other fantastic tools made by other participants. The wood is purple heart, and it comes from my brother’s service in the US Army in Afghanistan. The wood was in the dumpster after having been used under outriggers on heavy machinery. He brought a couple of pieces back with him once his deployment was over.
I laminated a few pieces together, cross grained, for the fence. Since I used the captive wedge design, I included a 6 degree space in the laminations so it would be smooth. The practice gauge I made had an irregular face made via chiseling and filing, and I didn’t want my “real” gauge to have irregularities. I made the beam similarly with purple heart laminations. I sized the beam via hand planing, trying to avoid splintering. After the beam was sized, I marked the mortise in the fence, cut the bulk of the material out with a Forstner bit, then finished the mortise with hand chisels and/or filing.
I made two blades out of one jig saw blade, filing one to a point, and the other as a fingernail shape. The third blade was a full-length jigsaw blade shaped to a point. The blade is also held via a small wedge in the beam, also with a 6 degree angle. No finish applied to the gauge or wedges—only Johnson’s Paste Wax was used.
In the south Louisiana tradition of “lagniappe”, I included a spare purple heart wedge each for the beam wedge and the blade wedge.
I know I mentioned this in previous posts, but if you get a chance to participate in future LJ swaps, please seriously consider doing so. I found this marking gauge swap a great opportunity to challenge myself to try new skills. It was neat personalizing the gauge for JayT, and I am glad he found it useful.
EDIT: Thanks to JayT for providing the finished pictures. I forgot to take photos before I boxed it up and mailed it!
