Why spend $100 on this jig? Print one yourself! If you have to ask what this is, then it probably isn't for you. But I'll be nice, it's a jig to put a fingernail grind on a bowl gouge. Please, those who do know, do not laugh at my horrible gouge, that's what 6 months of free hand sharpening a gouge will do to it. Hence, why I made this thing.

I'd have a pic of it in use, but I'm still building the rest of the sharpening jig.

Based upon Marius Hornberger's video on his (wooden) shop built jig (https://youtu.be/sfmIv0iXjis). I made some minor changes, based on the medium used, but the parts are directly copied from his plans. I'm using a washer held in place by a nut, in the "wrong" order, to hold the gouge in place. Works fine for my 3/8"(?) gouge, but a larger gouge may require something like a threaded washer, as the nut takes up too much space.

Print the arm with solid infill. I printed mine at 25%, and it's a bit flimsy. Usable, but I'd rather have a more solid arm. And since, ya know, if you need this jig, you probably have access to a bandsaw, so I'd recommend making the arm out of 1/4" ply. If you do, just note the holes are space exactly 2" apart on mine. The original (included pdf) was a bit different.

(Note: in assembled.stl, the nut is shown on the top of the block, it actually goes on the bottom. The topassembly.stl file corrects this. The assembled file was just a mock up to make sure everything lined )

IF YOU ARE HAVING ISSUES WITH SIZING: The M6 knob is metric, but every other file is in imperial, Inches. The M6 Knob is from a different project, and it's close enough to use for a 1/4" bolt, so I didn't think it would be needed to change the units. IMPORT ALL THE OTHER FILES IN IMPERIAL.

IF THE MODELS ARE TOO SMALL, SCALE UP BY 2540%.

March 2023 Update: I've added a shortened version of the top assembly for smaller turning tools. I have not tested it and it may or may not work, or even be assemble-able.
