I decided to purchase the Woodcraft 8” slow speed grinder on sale for $90 a few weeks back. I finally got around to finishing the table/extra storage for it as well as the basic grinding jig to do bowl/spindle gouges. Previously, I was using my worksharp 3000. I said it was good enough on these forums for lathe tools, but I knew I was actually in denial lol.

Don’t get me wrong, the worksharp 3000 did a great job at flat chisels and the likes, but for gouges it wasn’t the easiest to keep a consistent grinding angle, nor was it the fastest for sharpening them. I also always wanted fingernail grinds on my gouges but that is way too much material to take off with that. So I decided at $90 I couldn’t pass up this grinder. I’d make the jigs myself to save money over the wolverine ones thanks to some help in the forums, http://lumberjocks.com/topics/28920, and fine woodworking… http://www.finewoodworking.com/pdf/ShopBuiltJig.pdf
The cost of my “wolverine” jig and fingernail profile jig was around $10 thanks to scraps. The cost was mainly for the thumb screws and tnuts.

The clamp on the end is because I just glued this piece on, it was removed shortly after these pics.

I still have the fingernail profile jig to make, but haven’t gotten around to it, although I do have all the t-nuts and screws and dowels required. It sits in the dimple of this jig. The dimple sits 4 inches up from bottom of wheel and will be 7 inches out for that grind. For normal grinds though you just place it in the v groove of this piece and rotate. I was amazed at how incredibly easy it was to grind with it.

And here is the beautiful grind on it. I remembered to keep some water nearby and frequently dip in it even though it was high speed steel(from HF) it did turn blue on the tip pretty quick so I had to remove that bit but used water from that point on and it was perfect.

Hopefully I’ll have time to use my newly sharpened gouges this weekend to turn the pizza cutter from Rockler I purchased this past weekend, as well as two bottle stoppers and a bottle opener. I also need to finish up that bowl now that I have a working chuck :)

That is a beautiful bevel, Eric. Puts my freehand ‘multi-bevels’ to shame. Great job on the bench with storage- though a warning: stuff will expand to fill however much storage you have.

Thank you Donna. I’m sure your freehand bevels would put my freehand ones to shame though.

As a software engineer, I’m always think about scalability and ways to future proof so you’re absolutely right on warning me about it lol, but I appreciate it.

I have seen those kinds of jigs for turning tools but I have been afraid of them. They look like a recipe to have the tool wedge into the wheel. Is this unfounded?

I really like the lathe stand. I have been thinking about doing something similar with mine. (same lathe)

David, before I used it I would have thought the same thing. It is adjustable so you can get the correct bevel angle required, and no, there is no pressure against it like there is on the lathe while cutting. I’m able to very lightly hold the tool and touch it to the wheel after it reaches speed. The tool is just rubbing against the wheel, make sure the angle leaves some room to not dig in the tip though initially.

Btw, looking at the blank space for the drill press, don’t make the mistake I made. Get one where the table can raise and lower with a crank. For wood, it is much more usable. Less important with metal since most metal will be thinner.

Nice setup!!

I especially like the idea of having it so close to the lathe. It sure will save time and steps.

Thanks for posting this Eric. I was wondering how well it worked and I might get one now.
Great looking bevels on the tools.

Well, Thanks for the post Eric. Vicky and I had been thinking of getting a PSI jig for her lathe tools, especially after I really botched them up trying to sharpen them by hand. This saved the day, she was really starting to get mad at how long the pens were taking to turn. For about $10 in materials, I redeemed myself and can have her tools sharp and up and running again soon. Definitely worth spending the afternoon today making it for her. Especially since now—- I DON’T HAVE TO SHARPEN THEM FOR HER!
I owe you a beer the next time we go out!
