Hi, just wondering how people are getting more than 4 bowls out of a blank with the easy core system. Seems like you'd need to use each knife more than once, and its a lot of moving the base around? I have seen Chris Ramsey mentioned in a couple threads for his ability to get 9 (!!) bowls out of a blank. How?

getting 4+ bowls with the oneway easy core system.

The only way I can think of is to put the Oneway back on the shelf and pull out the McNaughton.

The radius of each cutter is fixed, but you do have some control over diameter and depth by where you bolt the base to the ways.
Unless I'm going for a nested set, I never get more than 3 or 4. Primarily I go for the money bowls. Getting four or even 6 bowls is easy. Getting nine would take too much planning.
He got nine bowls very easily out of the burl he had. I think if he wanted he could have gotten 3 more. I spent a few days with Chris and I wanted to see him core first and foremost. Here are 2 photos roughed and finished. At one time Chris had posted a written explanation of how to use the Oneway Coring System on WoW but I wanted to see it done. He did not disappoint and I am not sorry that I got rid of the other two systems I had. And now with the availability of the Hunter Core Pro which makes the Oneway system 200% better I am a happy coring camper.

The Hunter KorPro for the Oneway Coring System is SO good......that it can. be scary in a softer hardwood such as green/fresh cut silver maple and similar. I wish I could find the 3-second video clip that I sent to Mike Hunter of me coring Flame Box Elder using ONE FINGER to gently apply pressure on the handle of the Oneway coring handle. The sharpness of the diamond-shaped cutter is unbelievable in this application. Expensive little bugger and WORTH IT. Mike also retro-fits the McNaughton coring blades to accept his KorPro cartridge.
Hey Tim. I can’t believe the difference either! Did you make any height adjustments to the rig, or are you cutting right on center?
So what do you do to get 6? Mind explaining your process a bit?
How many bowls you can get from one coring blank depends as much on the size of the blank as it does on the turner. For a 6 inch deep by 14 inch standard bowl blank, I will get 2 cores, so 3 bowls total. That last little bowl usually isn't worth the effort. One figure you can use might be 1 bowl per inch of thickness. That 9 bowl set above comes from a burl cap, which is domed rather than flat, so you can get more blanks from a piece like that.

John - dead on center or a HAIR above.....buy not any more than that seems to be the sweet spot. I wish we could convince more turners to try the Hunter KorPro. I do not make a dime nor do I receive and benefit from pushing it. It is just that I was amazed at the difference in ease of coring it creates with a known system - the Oneway.
For sure! It doesn’t even compare to the original cutter. Can’t even say night and day, because it’s more profound than that! People balk at the “expense” of it, but when you can run through 50 bowls without even turning the cutter? C’mon! It doesn’t get any easier than that!
I know John- It really is the best single improvement in coring that I have personally used or seen. And I hope Mike is planning on retro-fitting the new Woodcut 4 coring system. It can core up to 18".......Otherwise it seems very similar to the Oneway.
I will have to try some minor adjustments - maybe raise the rig to get the cutter just a squeak above center. Every once in a while I get wicked friction and it takes more pressure than seems reasonable to advance the cut. Maybe I’m a shade too low.
Did you buy multiple cutters, or do you swap one from rig to rig?
Did you buy multiple cutters, or do you swap one from rig to rig?
John - I tried 1. The price point shivers..... And that 1 I swap between cutters. but the future clearly is that I will buy more, they make too much sense to not have them on more blades.
I bought a couple more from Mike in Chattanooga so I don't have to move the cutters. I should have bought 3 and had them for all my cutters but I only use the biggest cutters once in a while, next time. I know people look at the price and say Wow but I cannot state in words the difference the KorPro makes, you really don't know its worth until you've tried it. I don't know what Robo Hippy is talking about above that it is a burl cap that is domed. If you saw the piece before it was started it looked like any piece that you would core flat across the top. The Oneway Coring System is a lot more versatile than people give it credit for being. You are not limited in just one shape.
Can the KorPro be sharpened?
No, it is a “cupped” cutter design like some of the other Hunter products. It is a diamond shaped version of those. But you will get a lot of mileage from 1 cutter.
I have several Hunter products and they all have the cupped cutter and can’t be sharpened or honed, but their cutting action is so much like a gouge that you can’t really think of them like other carbide tools. Very smooth, very friendly, very versatile. Yes, they are expensive at first, but do the math on how long until your traditional gouge will be a nub and compare that to the mileage from a Hunter “carbide” tool and the gap closes remarkably (speaking of the other line of tools, maybe not so much the Korpro, but that Korpro is so smooth and fast it is worth it). IMHO for whatever it’s worth!
I know John Lucas did some experiments with resharpening carbide tools, including the cups. The cups did chip, which basically makes attempts to get a new edge on them useless. DMT makes lapping plates in 4000, and 8000 grit. I wonder if they may work better for touching up a cupped carbide cutter.

I’d have to look it up, but I think replacement cutters for the Osprey and Hercules are under $50 (CAD). Not bad for the thousands of miles of cutting they do.
Actually, the #1 cutter for the Osprey is only $26 CAD, so there ya go.
I just posted a link to a 10 second video clip of me using ONE finger to core with the Hunter Korpro on the Oneway Coring system
No link here.
I just requested access to view on Dropbox.
Just saw that in my e.mail. Thought it was a public file. I approved your request and will try to figure iut how to change the settings in Dropbox
Thanks

That’s amazing. Are you lined up so the top of the cutter is on center?
That is correct. If anything you want tot be AT center, or a hair above - but ONLY a hair.
