Honing a Spindle Gouge
Nov 3rd, 2018 at 1:41pm
 
Do you bother? Ive never done it myself but I recently saw this Alan Lacer video.

Im wondering if it might be good to do this for final cuts on a piece?
Ive seen folks honing stuff on a MDF disc loaded with compound, would this be a good option for turning tools?

Your thoughts Gentlemen. Smiley

I clean off the inside burr on my gouges after sharpening but the rest is wasted effort IMO.

Using a flat card to hone something ground with a round wheel is a pain in the ..., all you end up doing is hitting the two highest points. One changes the cutting edge angle and the other smooths off the heel. The center of the bevel doesn't usually get touched, if it did, why use a grinder in the first place.  Undecided

I'm of the school that "over-sharpening" is fruitless.
Sharpening to 800 and on up will be dulled down almost immediately, depending on the wood, the speed and all the factors involved. You may get only one or two revolutions before your tool reaches it working sharp edge, the place where it cuts the best the longest, I don't see the point in sharpening much higher than that. Different tool steels will have different qualities as far as cutting edge sharpness and longevity of said edge.

Just my two cents

This is an image  (exaggerated) of a hollow grind with the tow flats.
One on the cutting tip (bottom left), creating a micro bevel and on the heel.
As you can see, these two flats are aligned as you would get from honing with a flat card.

Not sure if it makes a difference ie; honing or not honing, but increasing numbers of turners here in the UK dont hollow grind turning tools any more.

Old Delta 12" 46-701 in great condition. Had it about 20+ years and turned 1 part.

May be a crazy way to do it, but I hand sharpen my tools on the Side of the wheel hence a flat grind rather than concave. Also a slower surface speed on the wheel and less chance to burn the tool. Dates back to my mold making days. Smiley

My first question about the video was how old was it. About 5 or so years ago. I would bet he is using CBN wheels now. As for honing, I was never very successful with the hand held cards. They always still left a burr. With our choices for wheel grits greatly expanded, the hand honing is a minimal requirement, and most of the time not needed, except for the skew chisel, which is a beast I am still learning. It works best with no burr at all, and the only way I can get that type of edge is with the honing wheel on my Tormek. As for honing most turning tools, not necessary other than very rarely for one of those difficult pieces of wood, which means wild and crazy grain and/or punky. Most of the time, it can be tamed with a 600 grit wheel. If that doesn't work, then I would try the honing wheel. We do tend to grind rather than sharpen, and the harder you grind, the worse the burr is. The very fine edges are great for finish cuts, but lousy for heavy roughing cuts because they go dull so quickly.

Personally I would prefer a platter type grinder with a planetary motion and a CBN surface.

Ed, I wonder if anyone has adapted a WORKSHARP type grinder?  I wouldn't like buying belts all the time for a belt sander, but maybe with the light grinding done they would last a long time.

This may be a better or at least easier to visualize image of what flat honing does to a hollow ground edge.

If one does wish to hone, a hollow ground bevel is desirable because less metal has to be removed to hone the cutting edge.  I will sometimes hone a skew or diamond parting tool, but I've never bothered to hone any gouge.
