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!

Paul, DAMN you did a good job, and sharp tools and pictures, But now you can't blame your tools anymore G Yes a good grinder you need, try to find a good old used (or unused G) one, let it run, feel if it runs good, and you will have a better grinder and maybe even for a steal, if you have to buy a new one get a 8" or 10" 1700rpm one. You will never regret buying the best Have fun and take care Leo Van Der Loo Paul Kierstead wrote: So, my journey down learning-to-turn is still fun.

Paul
Great job and thanks for the remarks on the site. You are right. One of these days I have to upgrade the sharpening page. I have the stuff ready for grinder set up and need to do some better pics for the jig, but it is so simple that anyone can do it anyway. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |

This is great.
I would love to see more people challenged to aim for perfection at the cutting edge. I have recently returned from Australia where I demonstrated tool shaping and sharpening methods and challenged the club members to aim for a quality egde when sharpening. If it isnt happening at the tool sharpening center then it will never happen at the lathe. Go Paul "Paul Kierstead" wrote in message news So, my journey down learning-to-turn is still fun.

Hi Darrell
You have one off the most help full sites for all us turners, and I thank you for that, as you say its all so simple, yes when you know it's that but there are a lot of people that have made use of your straight forward advice, i made some of your angle wing and banana boat bowls, they where fun, took some as gifts for friends in holland, and were well received. Have fun and take care Leo Van Der Loo Darrell Feltmate wrote: Paul Great job and thanks for the remarks on the site. You are right. One of these days I have to upgrade the sharpening page.

Darrell - you are famous! I was in a lathe specialty shop (should probably remain anonomous) a while back. I explained I was a newbie and was having trouble with gouge sharpening. I got a pretty good demonstration from a salesperson on the Wolverine system and was impressed. Then, to my amazement, he said if I didn't want to spend the cash now, go to your site. Your home-built solution "did a fine job" He even pulled you up on the store computer. I was very pleased with the honesty but don't want this guy to get fired. |

Wow. I am flattered and a bit embarrassed. All I did for my jig was to look
at the old Ellsworth jig ideas before he got them pre-made, stare at a couple of commercial models, and picture the end of a gouge moving inside a projected cone. Then I built what would work. This is cool. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |
