Roll your own sharpening jig (I did it!)
So, my journey down learning-to-turn is still fun. Sharpening has been
kinda ... variable would be kind. I was having some odd catches with the spindle gouge (haven't tried bowls yet) and a close examination of the edge proved to show it a disaster. I decided that free-hand sharpening was a lovely goal but I need to learn one thing at a time. Alas, money is short, beside I have resolved to quit buying gadgets and Sorby's comes in at C$115 or so. Off to search for jig plans. Ah, still one of my favorite newbie resources, Mr. Feltmate has a page on his jig: http://www.aroundthewoods.com/sharp.shtml Now, I will admit that "plans" is used loosely here, but still, it look so simple compared to some others I found, and highly functional. So I built one: Basic station: http://homepage.mac.com/paulkierstead/tmp/station.jpg Anchored using 1/4-20 inserts in the table top, off-set holder to work around issues with this grinder wheel. I first put it to use on a roughing gouge; results: http://homepage.mac.com/paulkierstea...ughing_tip.jpg Worked pretty well; *Very* even grind. Mind you, the roughing gouge was not in that hard of shape. Still, impressively easy to use. Next up was to do a spindle gouge, a much more complex grind. First of, gotta make a holder: http://homepage.mac.com/paulkierstead/tmp/holder.jpg And then the results: http://homepage.mac.com/paulkierstea...pindle_tip.jpg Marvy stuff; ok, totally awesome result. Some lessons learned: - Those white fine grit wheels really suck for removing a lot of HSS steel. I wore a groove in it in record time. Grinding out the spindle gouge required re-truing the wheel 3 times, and I am not talking about being picky here; we are talking major tracks in the wheel. One of these days I have to get a real grinder with a hard coarse wheel on one side. - you don't need intricate plans. this was one of my most ad-hoc things I have done and has been a hard lesson for me: Just do it! - Home-made jigs do not have to be second class; this works amazingly well. - If I can smack this togather out of some shop scraps, anyone can!
