Lathe Gouge Tool Sharpening Jig

I am new to wood turning and was frustrated with how inadequately I was able to sharpen my knives freehand so I designed and made this jig that rotates on its axis and gives a smooth facet at the cut for my gouges and a few scrapers. The jig adjusts for various lengths and angles. There is a micro-adjustment at the end for advancing the gouge towards the grinding wheel. The walnut holder locks the gouge and is the part that rotates. There is a rubber tip on the hold down screw that protects the gouge.

Thanks! I’m pleased so far. It is going to be an expandable modular sharpening system capable of sharpening a wide range of knife blades. I will post those as they are finished.

Thanks! I’m sure there will be a few more that I’ll need to add as I expand it and add options but for right now it seems to work well. It’s a big improvement over what I was doing before.

Great shop idea! I hate spending $$$ on overpriced sharpening attachments. Will add this to my favorites.

Thanks Hutch. More to come as I am creating modular attachments for other blade types.

Really nice! I like it.
I’d love to see more photos of how you built it. (How is the chisel holder attached to the base, for example?)

Thanks! The lower holder is dovetailed and glued. The upper maple chisel holder is simply glued to the base. If I feel that there will be more stress than I had anticipated I will reinforce it with screws.

The walnut chisel holder is oversized to accommodate a larger chisel hence the PVC shim used to bring the chisel up to the correct height on the axis. It simply rotates freely in the upper maple chisel base when grinding.

The walnut handle has a 1/4” threaded rod tapped into the handle and it screws into a brass threaded insert in the walnut hub.

This is great! Kudos on an orginal design! I have searched high and low on the internet for all the possible DIY sharpening jigs for turning tools, I ended up making a replica of a Wolverine system that works pretty good, but I have always thought there could be some real improvements. Id love to see this jig in action, in like a short video if you have one. Just to see how it actually works. Thank you for posting.
