Oneway coring system

[kevin nee]

Hello, I have an opportunity to purchase a complete ONEWAY CORING SYSTEM it is for a 24 inch swing. I have the POWERMATIC 3520 with the 20 inch swing. The owner of the Deal says I can just cut down the post and start coring. Has anyone done this with success? Thanks in advance, Kevin

[Don McClure]

Your other option is to buy a new base that fits your lathe...I went from a 20 up to a 24" swing and got a new base...sold my old one.
I like the system a lot. They also now make carbide cutters for this system.

Kevin, you can modify almost anything with the right tools, but an advantage of buying a new base and not cutting anything is if you decide to sell it someday you will be able to offer it to a wider audience. If the bases are interchangable you might even be ably to sell the 24" base to someone who already has the system and moved to a 24" lathe.

But to your question. i do a lot of metal work but I've never looked at the Oneway. If it has a standard solid tool post that fits in a banjo, cutting that down is a 10 minute job - I just cut down a spare Robust tool rest to fit a smaller lathe. If the "post" that needs to be cut down is more complicated, say is a machined part with brackets and hardware to tighten it may require things like drilling, tapping, maybe welding. Maybe describe the design and show some photos. Or someone who has one might.

One of the clubs I belong to is going to be having a coring demo on 9/19, where the Oneway EasyCore, McNaughton, and my Woodcut BowlSaver Max 3 will be demonstrated all in one evening. I will be showing my system. It will be a great way to show our nearly 100 members the systems and their pluses/minuses. I can say that I am pretty happy with my WoodCut BowlSaver Max 3. It can adapt from 18-24" lathes. The earlier Bowlsaver could go from 14-20 if I recall correctly, which I may not be accurate on that, without looking it up.

That reminds me........I have to rough out a coring blank soon!

Roger, if you can use or know anyone who wants the McNaughton bowl saver DVD I have one and that I didn't find until after I sold my McNaughton. (And can't remember who bought it.) I'd be willing to trade it for a piece of wood or for the recipient to make a small donation to a local children's charity.

I think it's this one:

I don't have my oneway system in front of me, and I'm going by memory here, but that doesn't sound right.

The knives are shared between the different bases. They rest on something inside the tube. Presumably it's higher on the taller bases. Does it move up and down? Can you adjust the knives enough so they'll work if the tube is 2" shorter? I don't know. But I'd look at it very carefully before you buy it if that's your plan.

Also remember that you probably need a replacement for the bed gap bolt thing since I don't think they're the same.

[Leo Van Der Loo]

Kevin yes you can change the Easy core system, you will have to shorten the heavy base tubing and also the shafts from the knife sets.

On the bottom of the support finger and also on the knife bar shaft is an adjuster so you can adjust the set exactly for your lathe and have to do that only once

I will add a couple of pictures, so you can see this for your self, rather than having to go by all the talk of those that do not have one or even used or seen one.

A clamp block that fits your lathe is needed also, Oneway makes those in 15 different sizes, just measure the distance between your lathes bed ways,

[Bob Bouis]

Well, I looked at my set for 20" swing lathes and the pins inside the tubes that the knives actually ride on appear to be adjustable in height, or at least are removable with a set screw. So presumably you really can cut them down. Also if it was 2" taller, you'd only have to cut about an inch off one side and maybe 1.5" on the other. So very doable.

[David Delo]

Did you do anything on this Kevin? Buy a new base or modify the existing one meant for 24" swing?

[kevin nee]

The used deal fell thru, he decided to keep it. I bought a new one direct from ONEWAY with the two smaller knives.
i used it for the first time today. Very impressed. I got 3 bowls from a 13 inch Norway Maple Burl. Very user friendly.
ONEWAY told me you can just buy the Knife & Support tube for around $60

[David Delo]

Thanks for answering Kevin. In the same boat as you were, just trying to determine which route to pick.

[Reed Gray]

I had not heard of the carbide tipped cutters for the Oneway. Went to the web site and couldn't find it there, so I sent an e-mail. They said yes, the rumor is true, and gave me a part number, but I still could not find it. I asked if they could send a picture. Waiting....

The Oneway coring system is easy to modify. Mine was originally for a 16" swing, then I lengthened the tubes for a 24" swing and the last modification I shortened the tubes for a 18" swing. There is some adjustability with a set screw in the bottom of the shafts but it is more for fine tuning then making large adjustments.

Reed, Craft Supply has the carbide cutter listed on line for $50. https://www.woodturnerscatalog.com/p/134/6964/Oneway-Easy-Core-Carbide-Cutter?term=coring+systems

[John Spitters]

In order to have your Oneway easycore system fit the swing of your lathe you only need to buy the different length base tubes, not the whole base plate system. Oneway does not explain this on their website but if you call them they will let you know what is “only” needed to fit your system to a new swing. Apparently the cost is only approx. $50 Can. There is no need to cut down the existing tubes at that price.

[Reed Gray]

Hmm, it looks just like the standard one. I wonder what they do when it is time to sharpen it??? I will have to chat with them at the Portland Symposium. Honing perhaps?

I did get an e-mail back from them saying that the cutter is identical other than material. Sharpen by honing the surfaces on a diamond plate, and they did not think lapping fluid was necessary. That would leave no burr on the cutting edges, and to me, the burr is what cuts best. I told them we need to play at the Portland Symposium...

[Bob Bouis]

In theory I like the idea, but I have tried honing the regular oneway cutters. The result wasn't good. I say that with the caveat that I maybe don't know what I'm doing, of course. But for me they cut way better when sharpened with an 80-grit wheel than with a hone or a fine wheel.

Maybe you could use a $10 chinese diamond disc on a mandrel of some sort or a worksharp or the like.

[Leo Van Der Loo]

Carbide being a very hard and brittle material, I would expect a burr to be very difficult to achieve, and because it being brittle I would expect it to break away almost instantly.

HSS in all the different compositions, is more forgiving and tougher, a burr on that will last longer, even if that is a relatively short time.

Carbide does have to rely on its extra hard wearing material to stay sharp, maybe the best material when using it on wood with silica in it, where HSS does not keep an edge, just all IMO :)

[Peter Blair]

Kevin when you get your system set up you might like to take a quick look at what I did to ensure I no longer make funnels with my Oneway Coring Set.

It is especially useful for me as I use a multitude of different chucks, each is slightly different in as much as the distance they hold the piece from the headstock.

You can't put a bur on carbide cutters so that is why using a diamond plate the best way to put an edge on the cutters.

Tungsten carbide isn't a metal, it's a carbide (think silicon carbide grinding wheels). Tungsten carbide cutting tools are actually somewhat like a matrix grinding in the sense that tungsten carbide grains are mixed with other materials such as titanium carbide, tantalum carbide and niobium carbide to improve the properties of the material when cutting. The size of the grains is actually a fine powder ranging between about 0.5 micron to 10 microns depending on the desired grade. The "glue" that binds these materials together is powdered cobalt. The mixed powders are molded and heated to melt the cobalt "glue" to form the cutting tool.

[Reed Gray]

Well, I have yet to put that to a test, and have been told by many that it is impossible to put a burr on the carbides. I can turn a burr on stellite and tantung. I know the tantung is a cast particle metal similar to carbide, but don't know the exact differences. I will find a dull cutter eventually and give it a shot. Maybe at the AAW Symposium in Portland this year... I was told that I couldn't burnish a burr on M2 as well....

I don’t agree with that stellite or all tantung metals are like carbide, but here’s some info on it if you want to get up to speed on some of it, it is quite good.

Info on tantung at page 32 - 33

I think this will work

[Reed Gray]

Made my head hurt trying to sort that all out..... I do know how to grind that stuff though. Of interest to me, the micro photos of stellite, tantung, and carbide were all different magnifications, so hard to compare. For me, similar means they have similar properties as in stellite and tantung will both cut for about the same amount of time before I have to go back to the grinder. The stellite seems to take a finer edge, and the tangung is a bit more coarse. Neither are as hard as the carbide, but they can be easily resharpened. So, I guess that translates as some where between M42/V10, and carbide, though I don't know how to compare edge durability. I would consider it closer to carbide than to the others.

One interesting thing to me about the stellite is that is made up there in Canada. When I first contacted them, they sent me free samples. A year or three later I wanted to purchase some, and they would only sell the cast blocks which were around $2500, and I would have to process it myself. I asked if they could put me in touch with one of the people that bought those blocks from them and they said yes, but 'it won't be today.' That was a couple of years back.... No idea of Oneway considered stellite for their tips as it would be far easier to sharpen...

Great reference book, Leo.

Kevin,
I own a set of bases fir the 20" Powermatic. I had to buy taller bases to fit my present lathe. Send me a PM if you want to discuss them.
