Wood Turning Tools Need Sharpening Regularly

Sharpening Jig for woodturning tools

For the beginning wood turner and unfortunately for many long time users of a wood turning lathe, sharpening is a mystery. Sharp tools make for great shavings, better surfaces off the tool, less sanding, and more fun. Turning wood with a dull tool is hard work and leaves a lot of work with lots and lots of sanding. wood turning sharpening image
First of all, what is sharpening not for the turner? It is not all those honing stones and sandpaper setups that the wood carvers and other wood workers use. A well tuned hand plane needs a finely honed blade to bring up a good shaving. Many of us are going to sharpen our planes and stones with a 1000 grit water stone or better and then guard the edge. wood turning sharpening image
That super fine edge simply will not last for us on thewood lathe. There are some who hone and strop a wood turning tool and claim that it out turns and out lasts a ground edge. Leave that argument to the blog. For now I am going to consider setting the grinder up as our lathe sharpener. Consider that you may be planing for a half hour. A good stroke for a hand plane is 18" and a steady pace is 1 second per stroke. So a plane blade covers 1/2 mile in 30 minutes;
(1.5'x 60 strokes per min x 60 min per hour x 1/2 hr / 5280')

while a wood turning tool addressing a 6" diameter log covers 10 1/4 miles in the same time if turning at 1200 rpm.

Plus we tend to be turning logs that still have the bark on them and a felled log is likely to have grit, stones and other edge dulling debris in it. A quickly dulled edge needs to be quickly sharpened and back to the lathe. green wood
My tool of choice for this task of sharpening wood turning tools is the typical mass market grinder set up simply for the turner. grinder abrasive wheel
