How many lathe tools are enough?

[Webb Willmott]

Like this. Many sets of the HSS look this way.

I know that I have given away well over a hundred turning tools. I have sold probably 25 or so. If I were to count what are in all the drawers and cupboards I'm sure it would be north of 250, the majority of which are Hunter and Thompson. I had a box of Craftsman turning tools (I think there were 18) that were brand new. They were all black and smooth. I do not know if I still have them or if I gave them away. If I find them I'll post a picture.

Looked for them yesterday and I cannot find them so they were probably given away.

 

[Steve Tiedman]

In 1995, when I naively bought the POS Craftsman monotube bed lathe, I also bought their 4-piece tool set (small skew, diamond parting, small scraper, and something that one could mistake for a spindle-ish gouge sorta shape that in reality is just a tent stake).

I think the skew and scraper are still in a drawer. The gouge got thrown away when I bought a real spindle gouge a few months in. If I ever become king of the world, I'll outlaw all diamond profile parting tools, freeing turners everywhere from their miserable, misguided design and "benefits" of use (I'll stop at that), same with oval skews... what the "H" were they thinking? Anyway, What was I ranting about...? (You kids, get off my lawn!)

Interesting how our experiences differ. Parting tools: I use two fluted, one flat (Thompson) and four diamond cross-section (one large), and several micro parting tools. As I mentioned, the diamonds are my favorite for most things. But we each work differently.

I did have a student who had trouble with a diamond parting tool until I gently explained again and again how to use it. I do use a custom grind which makes the tool more useful than any of the stock grinds.

I will graciously accept donations of any “diamond” parting tools from unsatisfied owners. I could regrind them and the turning lives of several friends and students would be enriched.

And no attempt to be contrary: I keep and often use two oval skews, one I bought, the other I think given to me by someone who didn’t use a skew. They are more difficult to sharpen free-hand on a platform than flat-sided skews, but otherwise no different in use.

We can agree, however, on the monotube lathe! Mine was the Ridgid (copied or licensed) of the craftsman. It’s only redeeming feature was the excellent beginning turning course in the back of the lathe manual The Craftsnman 6-piece tool set was great and I still use it: wide skew, forged shallow spindle gouge, “continental” roughing gouge, round-nose scraper, parting tool, and can’t remember the other.

There have been many valid reasons for having a large quantity of tools, particularly for those that are teaching.

While my own stash is in the 50-60 range, I don't do that much teaching these days. What I did observe was that scale and complexity of the various turning projects will dictate to some degree the special tool design to achieve the intended results. Examples below all required different tools, many being specifically ground.

 

[robo hippy]

Hmm, which tools do I use most???? Well, as a bowl turner, once turned, I use scrapers for all of my heavy roughing, specifically the Big Ugly tool. I use a 40/40 grind for the outside of a bowl, and the 40/40 on the inside down to the transition, and then a BOB/bottom of bowl tool for the transition and across the bottom of the bowl. My favorite is a spindle detail gouge with a ) shape nose and a 70 degree bevel. I have a number of shear scrapers, a spear point for the outside and a couple of round nose or ) nose shape for the inside of the bowl. I have a number of NRSs/negative rake scrapers for the inside and outside of the bowls, but they work better on dry wood which I almost never turn. That covers my bowl tools, almost.....

Ooo - it would be interesting to see the set of tools you use to make each one of those, especially the special grinds (unless they are carefully guarded secrets!) Might be an eye-opener for some and spur some new experimentation and interests!

I also grind some custom tools but only a few are unique to a particular project. I once hand to grind a tool to carefully cut the string drive grooves when making take-up spools on a friend's spinning wheel. Her spinning wheel came with just one spool.

For those who'd like to make a little money with turning, contact your local hand spinners guild. There are ALWAYS people to need wooden replacement parts for spinning wheels. Some want drop spindles for spinning by hand, easy to make. These allow making yarn from fibers anywhere. I even made a special "supported" spindle a friend wanted for spinning while riding on a bus.

Many drop spindles available cheaply and crudely made. We know someone who sold them from wooden wheels made for toys, fitted a dowel rod for the shaft, spray painted with colors. One made from good wood with some style is prized.

Bloodwood and maple.


There is a world-wide community of fiber-arts enthusiasts - shearing, carding, spinning, felting, needle-felting, knitting, crocheting. When you have camelids, you meet many who want to buy fiber, especially alpaca. I could sell all the yarn bowls I could make. (but I don't sell)

Strange as it may seem, I like my diamond parting tool and oval skews. I can understand why you don't like them if you don't have a Tormek. There was a special Tormek fixture for holding both of those tools. Unfortunately, Tormek revised the fixture so it no longer works as well with the diamond parting tool.

 

[John K Jordan]

I like my ... oval skews. Tormek revised the fixture so it no longer works as well with the diamond parting tool.

I've sharpened the oval skews on the Tormek but never the diamond parting tools. For that I use the platform on the Wolverine. When I get a moment I plan to machine a jig to hold the tool perpendicular to the wheel. Sometimes I accidentally introduce a slight angle on the cutting edge and have to regrind.

But since I bought all the original jigs that Tormek had (back at the birth of Tormek, I think) and later bought a second (used) Tormek that came with more jigs, I looked through jig drawer and found the SVS-50 which looks like it could have been designed for the oval skew. Inside it has "V"s on either side to hold the edges and a lip that slides along the Tormek.

Long time ago I made an adapter to hold an extra Tormek tool guide bar so I could use it with a bench grinder AND not interfere with the Woverine/Varigrind use. I had to special order the bracket that holds the bar, made the mount of of white oak, cut away to clear the Wolverine handle.

I locked the oval skew into the Vs, set the angle to match what I'd ground by hand, set the bar distance for the bevel angle and with 30 seconds of sharpening on the 600 grit wheel plus a few seconds stropping had a perfect shaving-sharp edge. If not for your post I may have continued forever in my fumbling inefficient ways. Thanks!
I ALMOST remember using the jig for these skews a long time ago but forgot. (worthless memory...)



I do love the oval skews, find them easy to control, great for planing cuts.

Now, do you remember which jig will hold the parting tools? Maybe I'm using the revised version.

I like my diamond parting tool ...

BTW, this is my gradual evolution towards the perfect diamond parting tool grind. It's getting closer but needs another go. By having the upper bevel curve to nearly horizontal as it meets the widest part of the tool it works more like a skew peeling cut. For me, this angle cuts quite well. The only thing I do with the bottom bevel is hone it lightly to resharpen a bit before going back to the grinder. I find the diamond cross-section shape perfect for clearance on the sides, especially if I very slightly twist the tool back and forth around the tool axis during the cutting, may just a couple of degrees in each direction.

Another reason I like this parting tool is the width of the cut is PERFECT for sizing with the kind of calipers I often use.

I was looking at some old Craftsman tools and the finish on the steel looked like orange peel paint or a rusted tool that was painted black. Then I looked at fleebay and all the sets looked that way. There must be a reason Craftsman lathe tools were finished that way. Why?

I pulled out all of my old HSS Craftsman tools. While the sides of the tools are not polished, they don't have the orange-peal surfaces you showed. I couldn't find the spindle roughing gouge, prob gave it away.



Could some over-zealous worker have had too much fun spraying? Is it a coating that will scrape off?

The problem, by it's design, is that for a diamond parting tool to work properly by limiting tool contact within the kerf (its advertised benefit), the cutting edge has to be dead-on at the widest line of the cross section. If not, the wide section is not able to get into the relatively narrow kerf. In John's close-up image of the parting tool, the edge is below the widest point. Then, as John points out, you have to swing the handle left and right to widen the kerf to clear the widest cross section. But, with a normal, uniform width parting tool, one should swing the handle slightly left and right anyway (a fraction of a degree, hardly noticable in practice) to create clearance for the tool sides within the kerf. And placement of the edge on the height of the tool is not critical at all with a normal parting tool. So that begs the question, what is the point of the diamond parting tool if it takes more care and deliberate practice to keep it sharp?

Same for the oval skew, essentially the same shape as the diamond parting tool, but lacking the hard angles. Rounding the sharp corners of a rectangular section skew gets it to not beat up the tool rest, but with Sorby bringing the oval to market to solve the same issue, they went too far and removed a lot of steel from the tool. Completely unnecessary, and making it difficult to sharpen without complex jigs. 20+ years ago the discussion boards of the day were constantly criticizing oval skews.

Diamond parting tools and oval skew chisels, two tools trying to offer solutions to problems that never existed.

@John K Jordan You probably didn't know that @Webb Willmott also builds airplanes so may be overloaded with aeronautical tools but still working on turning tools.

I know I have 28 wood planes but no idea how many turning tools. Most definitely more than the number of planes.

I use four. 1/2" bowl gouge, skew, parting tool and interior bowl scraper.

I just saw this. I usually don't swing the tool handle from side to side. That would be a problem for a deep parting/sizing cut. I find it better to gently twist the tool handle, left and right (counterclockwise then clockwise), an entirely different motion:

"I find the diamond cross-section shape perfect for clearance on the sides, especially if I very slightly twist the tool back and forth around the tool axis during the cutting, may just a couple of degrees in each direction."

I reiterate: I love the diamond parting tool. I like the tapered fluted ones too, use two different sizes, but the diamond gives a nice flat bottom for perfect sizes where that's critical.

You are correct, good sir, you did not say "swing". Sorry about that.

I still think diamond parting tools and oval skews should be dumped into the middle of the ocean! Okay, a bit harsh. Take them to the scrap yard. Or, use them to pop weeds out of the lawn, there we go!

If HSS, you can always grind them into some custom tool. I do that.

Better yet, send them all to me. I and other turners I know will use them.

Thanks for the offer, John, but I already re-ground the diamond parting tool many years ago, and I own no oval skews.

I didn't grind the diamond profile completely flat to make a rectangular tool, but I flattened it a good 1/4" or more on each side, and now the cutting edge does not need to land critically on the widest part of the diamond rib dimension. Including the top and bottom flats, the cross section is now a rectangular-shaped octogon (i.e. does not have 8 equal sides) rather than a hexagon. If this would have been the original intent of Sorby et al, the tool would have always worked just fine. But as a diamond profile, one needs to have critical placement of the cutting edge right on the very widest line of the diamond shape for the tool to work. If not, the tool will not enter the kerf; it will not cut at all.

Yes, of course, shouldn't need to be said to keep the cutting edge at the max width. I've started grinding my diamond parting tools this way, they cut well (and also never bind if used properly):


I've experimented with different grind profiles. The one at the bottom is my favorite so far.
It does make them "one side always up" tools. I had to put a red "X" and a blue dot on the bottom and top of the handle of one to remind a student!

Note that the parting tool that Doug Thompson makes is entirely rectangular in shape, machined from 1/2" round bar stock. It also works well.
Don't have to worry about having to understand the evil width of the diamond parting tool.

Note that for decades people have ground thin parting tools from kitchen butter and other knives. John Lucas made one from a drywall saw blade. He also made one for his miniatures from a kitchen paring knife with a tapered blade. A google search will show lots of options.

One thing to remember about parting tools in general - if making a very deep cut with any parting tool, say deep sizing or even parting off a box or bowl, it's helpful to make clearance cuts on one side of the groove. A clearance cut doesn't have to take off much, just a "whisper" is enough.

Another thing I always do when using one to part off the work is never cut all the way to the middle. This will avoid breaking the last little bit and the risk of pulling fibers from wood, likely making holes difficult to repair. Instead, I part until the piece is held by just a very thin cylinder, then stop the lathe and use a thin saw to cut the last little bit. I clean up the nub by hand with a sharp skew.

This video might be helpful. Dick Sing mentions right off the bat that parting tools are often misunderstood. He shows a variety, with his favorites made from flat bar stock 1/8" and 1/16" thick. He also mentions the importance of a sharp parting tool! Duh. (They are cutting tools, not scraping tools.) Some of his grinds are interesting. He illustrates the movements needed for a deep cut, the same curve you would use when making deep peeling cuts with a skew. He points out the importance of grinding a diamond parting tool so the cutting edge is at the widest point.

My favorite it a standard rectangular, 1/8" wide, about 3/4" tall, that I bought from Packard a bunch of years ago. I think it is a Crown, maybe a Taylor, regular ol' M2 HSS.

The concave/slightly convex in John's photo, a pro that demo'ed here in MN 20-some years ago showed that profile, and I went right home and did that to my diamond tool, right after I flattened the diamond profile. Works well as a result of the more acute bevel angle at the edge.

 

[Bill Boehme]

I've sharpened the oval skews on the Tormek but never the diamond parting tools. For that I use the platform on the Wolverine.

I was confused about the diamond parting tool. Actually, the Tormek jig has not changed. The Sorby sizing tool is the thing that has changed. It no longer has a notch for holding the diamond parting tool.

I usually get old turning tools from other woodturners I know. Sometimes they get new tools and have more sense then me and give away or sell the old tools. At one demo I mentioned how much I liked a particular parting too - the next meeting someone gave me his!

Our club has a Silent Auction every Dec at the Christmas party that benefits the club - lots of times people bring and donate tools, maybe some they don't use anymore, sometimes they don't understand what they have, and others don't see the value. I got an brand new Grex random orbital sander this way a few years back for $30 - it normally sells for over $125. I take tools there too - last one was a massive scraper I hadn't used in forever. Sometimes people donate tools to our annual wood auction.

Sometimes people give me tools they don't use much since they know I sometimes teach and send some students home with tools.

I haven't been to a yard sale since can't remember when.

On that note, may I introduce you all to the work of Golding Fiber Tools. Golding’s RingSpindles are likely the most immediately relevant to this audience. But you’re really, really missing out if you skip their Spinning Wheels. Was turning involved? Almost certainly… but. The spindles are stunning, but the wheels are the true passion projects.

Incredible! I've never seen any that fancy!

I've turned replacement parts to fix my own spinning wheels and those of friends.

The hardest was making some extra bobbins for a girl with an old spinning wheel and just one bobbin. I had to grind a point tool with a special tip to change the taper at the tip. A straight v-groove wasn't ideal since the string might bind in the pulley. Fortunately I had the original bobbin to copy!

[Kevin Jenness]

I have a few dozen tools, some of them rarely used, but I do use just about all of them. I use a Thompson 5/8" V bowl gouge the most. That plus a shaped scraper for jaw shoulders, a Thompson 1/2" spindle gouge, a pair of 1/2" thick negative rake scrapers and my Jamieson hollowing bar are in regular use, probably 90% of the time. If I were only turning bowls I could get by just fine with the gouges and scrapers mentioned.

 

[Bill Blasic]

Kevin the first tool I got from Doug Thompson was a 5/8 V and that has been my go to tool ever since. I probably have 8 backups in the drawer. For years early on Thompsons were the only tools I used but when I discovered Hunter carbide I found tools that sometimes replaced a Thompson in use and they also allowed me to get rid of more than a few of my hollowing tools. I met Randy Privett early on so I have both (captured and articulated) Monster hollowing systems of which I use the articulated almost a 100% of the time anymore. I have a drawer full of Kelton Hollowers that I should think about getting rid of as they get very little use anymore.
