This is the best video on setup of the OneWay Coring system that I have seen. Thank you!
Wow, thanks!
Thanks. BTW, I have a Oneway finger- twisted from being grabbed. So now I use a small paint brush to knock away chips.
That's a great idea!
This has to be a required tool for anyone who regularly turns large bowl blanks. Thank you for sharing. Have a great day and stay safe.🙂🙂
Well done Mike and John. Set up is important and delighted that you took some extra time to explain the set up process.
Thanks, Mike. See you in Louisville.
Perfect timing! I'm looking around at my options for getting into coring. Thanks for showing the KorPro bit, too. It looks like a real game-changer...
He also makes a tenon to hold the first blank! So I am not the only one advocating that! 😎
OneWay is IMHO the best coring system on the market. Thnx for this Mike!
It looks like the korpro cutter is the way to go with a coring system Mike. Thanks for the video.
Very interesting process …. Thanks for sharing Mike🇨🇱🤠
Excellent and interesting video. Thanks!
Thanks, Mike!
Wow! Well done you two! So many Qs! 1. With the Hunter bit, might it have helped blowing air in continuously from the opposite side? The Hunter cutter is definitely more efficient, but it therefore generates chips much faster. 2. How are the inner bowls then chucked up to form a tenon for a foot? Mike, would love to see a video of you doing that!
I will make one!
Great video, Mike! Question: Would the thickness still need to be 1.5 inches if you were coring a dry blank? Thanks... V
No. It would need to be thick enough for minor movement from removing stresses when hollowing and truing up when reversing, and for any design considerations like beads or texturing.
I found with korpro cutter works great on the #1 and # 2 knife but jams up more with #3 and #4 knife. I think the Oneway cutters work best with the bigger knife.
Thanks, that is useful feedback.
Great video! A few comments-
1. The Oneway has an angled top edge which self ejects chips better than the flat top of the Hunter. If you cut slow and steady the chips will continue to flow steadily and not clog and you only have to pull out to clear chips every minute or two instead of every 10 seconds like they were doing in the video. So it may be that cutting slower and clearing less may be about as fast. If Hunter had angled their bit at an angle it might have cleared shavings better, but don't know, maybe they tried something like that.
2. The carbide Oneway cutters ($50 per cutter) are absolutlely a huge advantage over the HSS. I had a hard time sharpening the HSS even with the jig. Sharpening carbide on a CBN wheel like John did is an iffy proposition- I'm not sure I could get a good edge.
3.The Hunter cartridge is $190 for one knife. You are going to be out a lot of bucks, for three or four knives, or having some downtime to change the cartridge from knife to knife, which I strongly recommend doing in a shaving-free region of your shop, on a clean bench with good lighting and, with my eyes, under magnification. 0$ (HSS supplied) vs $50 (carbide upgrade, pretty darn good) vs $190 (some better, maybe much better carbide) is a hard choice. But, in my view,, not the supplied HSS, one of the carbides, depending on your price sensitivity.
I appreciate your comments, Wes. I do not have enough experience corring to draw any conclusions. John prefers the Oneway carbide cutter. I only have one knife as I do not plan to core really big pieces so switching out won't be a problem for me. I spoke with a production bowl turner who just could not say enough good things about the Korpro. He was getting 30 or more cores before having to turn the cutter around to use the other side. I am looking forward to getting some experience with the Korpro. Like every thing in turning one size does not fit all. I can see changing the cartridge on each knife might take a few moments and buying 3 could be cost prohibitive. John gave me Oneway sharpening jig for my HSS cutter. I have so many other projects that coring bowls is not a high priority and I know if I do not do a bunch at a time, it will be hard for me to come up with a meaningful comparison.
I have the same korpo cutter,cuts great,but man,it is way over priced
