Spokeshave Sharpening Jig

[ken hatch]

I just wanted to add that if you haven't used a bevel up spoke shave you are missing one of the true joys of handtools. Woodriver makes a metal bevel up that is pretty nice and at the price might be a good introduction but a good wood body shave like the ones Dave's Shaves makes will have you if not throwing away your bevel down shaves will cause them to gather a lot of dust.

In use the bevel down and bevel up spokeshaves seem to have different areas of use.

Though once my bevel up spokeshaves were purchased and put to work, it was a spokeshave epiphany.

Jim,

Ain't that the truth. Rainbows and Blue Birds singing.

My approach to sharpening spokeshaves follows the strategy I use for all blades (with the exception of high angle BU plane blades) - hollow grind at the desired bevel angle, and then it is simple to freehand sharpen on this. This becomes a repeatable method which does not require any set up. Maintaining a sharp edge is then straight forward.

The only jig - if one is needed - needed is one to present the blade to the bench grinder to create the hollow. With the exception of the narrow, tanged types shown by Ken, I have not found a jig necessary.

Derek,

I probably don't grind as much as you do but for most irons freehand is quick and easy, for me the secret is keeping the bevel flat. Once it goes out of flat, if it does, then I grind and start over. Like you posted the narrow tanged ones are another story. I'm still not sure a dog bone jig is the answer but it seems to work better than other ways.

Hi Ken

I suspect my post came across with the wrong emphasis. Apology. It should have clarified that most spokeshaves do not require a jig to sharpen, but the narrow ones (like yours) certainly benefit for one, whether to hone or grind. It is a lot like honing the narrow bevel of a knife - it comes down to the amount of practice one has in working narrow areas, and how important it is to develop the specific skill vs working with the tool.

I set my water stones on edge, and sharpen on the side (now up) of the stones. That gives the tangs plenty of room to hang down, if needed. The sides of the water stones can be flattened, just like the faces. This system also gets used for small cutters like router plane cutters, so as not to worry about gouging a face of a stone. I use those diamond paddles for a lot of things too, and that looks like a good system.

Derek,

No problem, I didn't take your post wrong. The way I read it I agree with, most irons do not need a jig, the exceptions are the ones like the dog bone jig is made for. BTW, I've done the using the side of the stone like Tom does and it works and I've used diamond paddles, they all work to a fashion but if a blade is even slightly damaged I want to be able to take it to a grinder. That is what the dog bone is for. Some times I post incomplete things. MsBubba says I start most sentences in the middle and she never knows what I'm talking about. I tend to post that way as well, thinking everyone knows the backstory and I can start at the chase .

I finished the jig by drilling holes on the small end to hold the short cutters and filing/sanding the edges. It is not pretty but it is functional, the best part it fits the Tormek holders so I can use it on either the bench grinder or the Tormek.

It would work for shaves as well.

Lowell,

Interesting video. However I see two major flaws in using a file to sharpen a tanged shave cutter. The first is it would leave too rough a face, That could be fixed on stones but if that is the case why not start there. The other is holding the work while using a file. Even if you figured out how to hold the cutter the tange would get in the way of filing the full bevel end to end. I would guess you could make it work but I think there are easier and better ways.

I might start with a file and finish with a stone. It works on spoke shaves.
