Sharpening Woodturning Bowl Gouges and Scrapers Tools. Fingernail Jig Grinder - #66
Вставка
- Опубліковано 13 вер 2024
- I've been talked into how I sharpen my woodturning bowl gouges and scraper tools on my bench grinder using a fingernail jig.
There are many other videos out there on sharpening, and this is my method.
Like the jig I use in the video? It's made in the UK and is available on eBay here:

Thank you for a good idea!👍
Well done mate, a lesson in the art of grinding, kept simple, but very informative. There is far too much "Dark Art", regarding sharpening, and you have shown that there needn't be. I have to say that I was extremely impressed with your technical terminology throughout, the "slidey stick thing" is a very effective piece of kit. Great video Martin,.
Cheers
Mike
Martin, you know we love you videos. I have 3 words (?) C B N wheels. They are completely balanced, NOT friable ...no bits/dust coming off and can not explode, no need for shielding, take VERY little metal off tools ( therefore last years longer), no heat produced, quiet, and last forever ...almost,........ no dressing, do not get smaller with use therefore never need adjusting, quick...one pass. That are a bit expensive but in the long term will save you money, work and produce a better edge. FYI love tech terms, slidey bit.....stick thingy......makes all the more watchable!!!! Thanks again Martin.
'Slidey in and out bit' - thank you for keeping it technical :) Seriously, thanks for sharing your methods. I always enjoy your videos.
I just bought this jig and it’s really good for me as a beginner!
Love the slidy in and out thingy... Also really good that your grinder is turn on and offable
Very useful video. Thanks. I’ve just bought the bowl attachment so I’ll be on it tomorrow!
Great video, I've just got the same system and didn't know how to use it.
Some good information there Martin! :) Thank you for sharing, these types of jigs and how to sharpen your tools is one of the most important lessons for beginner turners.
Yuval.
Perfect. Clear and concise. Thanks!
Great video, Martin. And a terrific grasp of the technical terminology . Cheers. Dave
Hi Martin I have just hand made out of scrap bits of metal in my garage (workshop) a bowl gouge sharpening jig but had no idea how to use it you have just put me right on that thank you so much.
Brilliant. well explained.
Nice video with great angles on the sharpening and your tips are great. Thanks for posting and I like the jig you have.
Hi Martin,
When I first took lessons on turning, I was told "if you want to learn how to turn, the first thing you have to learn is how to sharpen"
So I learned how to sharpen freehand. Jigs make things sooo much easier and repeatable, although a little slower. For a quick dressing I still do it freehand (I did bite the bullet and buy CBN wheels(much nicer)). For reshaping I use the jigs, mine are "Wolverine" just like your setup - with the slidy in an out thing.
Your fine wheel looks like a 2" wide - much easier to use than a 3/4" wide wheel.
Cheers Paul
Hey ty for this, this made alot more sense then others I watched. I actually took a leaf spring today, cut it all up made my own massive custom scraper. making the handle out of oak right now. but I may get some african paduk for it. Then as soon as its turned resin it, so it keeps that gorgeous yellowish / orange
Great video Martin. It's amazing how well slidey out things work :) I really must practice my sharpening skills!
Once again a very informative video well presented for us. I have enjoyed your all of your videos so far Martin.
Hi Martin, I've just this morning received that very sharpener, not the scraper one, from Mick Chambers, £34.00, so thanks for this video. I've also noticed a dark line on my wheel and you explained that as well. Cheers mate.
Dark line on your wheel usually means that spot has become engrained with dirt etc...use the dressing tool to take a bit off and give a fresh surface
Nice job Martin, kept simple & as 'M.W' said, no Dark Art involved. I have the same jig but I also have an Ellsworth gouge basket & use the 2",4",7" set up for my grinder with 6" wheels. Works for me. Thanks for following up the suggestion/s for doing this video.
Regards ....... Geof
Great video Martin. We have the same sharpening set-up in our little workshop, even sounds like we bought the slidey thingy jig from the same guy too. Simple, easy to use and does the job. AND it was affordable!
Hi Martin,
A very nice and concise video mate.
I also bought the exact same Gauge sharpening jig but not been able to fix it to my grinding table. I'm pretty excited now after seeing you use it. Sharp tool's at last lol... PERFICK mate 👍
Beautiful video, Martin.
I sharpen my turning tools as well.
That's right, Martin.
For stump tool = More power, greater risk of injury, the workpiece is unclean, may even fall out of the jaws.
Sharp tool for clean surface on the workpiece, faster work.
I am thinking whether I should get myself a CBN grinding wheel.
Greetings Günter
Refreshingly straight forward.........it ain't rocket science.
Thanks Martin, I agree with Mike ( who I also watch) I have seen lots of sharpening videos using verious Very expensive jigs but I need to sharpen by hand. Jimmy clewes turns some upside down and uses a sanding belt, so, like woodworking lots of different "styles" I have a similar grinder, and sharpen by hand so your instructions help.. many thanks
Been a subscriber for a while but so glad I found this video. I am just a beginner and have the same bench grinder and will be buying that jig, think I have found it (£65 for both setups). I am SUCH a beginner I only have a 2nd hand lathe and NO gouges yet as budget it tight, but I will be getting the sharpening and extraction in place first otherwise I’ll end up grinding with blunt tools in a dusty garage
When you were sharpening the scrapers it was clear to see dark areas on the grinding wheel. This is where metal has embedded in the wheel surface, thus ‘clogging’ up the available grinding surface. The use of the diamond dressing tool is to remove this embedded material to expose a uniform grinding surface across the width of the grinding wheel. I hope this adds a little bit of useful information to your demonstration. Regards from Tasmania Australia.
Good fixtures for sharpening. Like!
Summer, lost in the country. Good Luck To You Martin.
Eyup Martin I just watched this video as I have a few of your others. I had to laugh at the "removable err stick" Ihave the same unbranded system. I call it the sliding in and out thingy only I changed my tighteny up knob thing for an Allen key. Great and informative video buddy thanks. Stay safe.
Very helpful, Cheers
You can’t say it enough to beginners to get your chisels sharp...even sharpened enough to shave with......it makes turning an even better experience.....👍🏼😊
Great video Martin. I bought the self same jig from ebay, but I think it was a friday afternooner. The platform was lying out by over an eigth in the width and then I lost the slidy in and out thing. So I ended up with a trugrind, does the same thing just more expensively. But a good explanation and well filmed.
Drew
Very informative and helpful...thanks!
Haha nice tshirt xD
I take it for bowl gouges with a different angle of flare you would adjust the fingernail jig grip placement?
I'm awaiting arrival of a bench grinder and similar sharpening jig
Glad i've got the pro edge system, couldn't be doing the slidey in and out bit...
Martin,
I really like your videos. I’m just getting starting turning and your videos are very helpful. You explain the processes very well, it’s easy to grasp what your doing. I was very interested in your grinding and sharping video. I’m in the process of building one of my own. Is there anyway you could send me a full picture of the flat adjustable jig attachment for grinding the scrapers. Thanks for your help. I’ll be watching.

Hi I have the same setup as you but im going to order a CBN wheel this week from Woodturners Wonders from the US
Great video Martin.
I bought the hobby grinder for Axminster and not too happy with it so only been using the Credit Card which so far has done well. I also got the fingernail jig off ebay (retured engineer) so probably the same as you have. I found it fit sperfectly for the bowl gouge (still need to raised grinder by a little) but for my spindle gouge it doesn't seem to be right.
Certainly interested in the flat jig you have which I will now see if I can find.
Very nice and informative, do you have the measurements for the slide thing?
Great video do you always use a swept back grind or do you still use a traditional grind as well.
Why you don't use something like tormek? Thanks for sharing your technique
nice video Martin with your u-tube clout I am sure one of the CBN wheel manufactures will spout you a couple one 80 and one 180 grit you will be a amazed you have a good technique to your sharpening however a wheel from the CBN variety will never ware out and the edge is so good most advancement since HSS was invented for turners
sharpening is one of those things that if you ask 10 different turners, you'll probably get 10 different answers.... Don't think anyone can fault your methods here.
When I first learned in my grandfather's shop, we did them by hand with a file and stones.. :P it works, but it takes up a lot of time that would otherwise be spent turning!! The jigs are HUGE time savers and let you get reproducible results every time.
Great video Martin, I have the same jig and pleased to watch someone that knows how to use it! Haha
I need to work on the full fingernail as I must have quite a bit of material to get off first as it's just an Axminster standard grind bowl gouge. I have seen Robert Sorby do sell a fingernail shaped bowl gouge but I must be able to get mine down to that shape?
Thanks a lot, Reece!
+Martin Saban-Smith Thanks Martin that's great I'll have a go tonight! Take care
Hi Martin, nice video! You don't happen to have the details of where to purchase the jig! Looks great and as you say some of the other options are very expensive!
www.ebay.co.uk/itm/133182236355
Cool video Martin. Thanks for that. I'm sorry if I missed it, but what is the rpm on your grinder? All I have is a high speed grinder, and don't really want to buy another grinder, if I don't have to. Can I sharpen with a high speed grinder? I've read that it's not advisable because it can take off too much of the tool and heat the tool up too much. But then others say yes, just use VERY light touches. Do you have any advice?
I have the very grind and have it set at the 23 degree position,,but im having the hardest time with it,,it seems like from the tip to the back of the wings there is a dip in it,,,do you thing the ellsworth jig would do a better job
Hi Martin! Another really useful video! Do you have a way of "finishing" the edge, or of polishing off any micro-burrs that come with grinding a tool?
I only ask, as i was reading the Mrs P's whittling book and they were talking about grinding then finishing the knives and i wondered if there was a transfer across to lathe tools?
+Martin Saban-Smith thank you for getting back to me! You will have to get used to my silly, non-lathe owner questions haha!
My I ask what diameter your grinding wheels are? I have heard 6" will work, but it might leave some concavity in the bevel. 8" is preferred I hear, but a new 8" low speed grinder is not in the budget. :(
The grinder in this vid is 200 mm, i did hear some prefer the 150mm because they prefer the concave curve, this is the reason some dont like the Robert Sorby systems.... no curve.
The grinder in this video is 150mm, not 200.
