In this video Ronald Kanne, woodturner in the Netherlands Shows you, in detail, his Mastodon. A huge bowl coring machine.
This video was previously shown at the woodturners worldwide symposium end of january 2022. Big blocks of wood, or even half logs can be mounted on the machine. The Mastodon is home made and not for sale... :-)
With a huge thank you to Jan Hovens.

About Ronald Kanne
Ronald is a wood turner in the Netherlands. He makes commissioned work and his own free work. And every week turns out to be a little too short to get all the work done... He also runs a webshop for other wood turners. It's called: www.dehoutdraaierij.nl. This webshop is in Dutch, English and German. The website that contains his own work is called www.ronaldkanne.nl. You will also find these links in the video.

Ronald great to see the machine in action after having turned bowls at your course that came off it. And very nice to hear you and Jan acknowledge the people who inspired you.

What an amazing design. The “Mastodon” is perfect for your business. Congratulations to your design insight and your friend’s engineering/manufacturing skills. I was just realizing that you offer woodturning classes in the Netherlands! So I thought, what a great opportunity to visit your country, meet you and your photographer (!!) and the opportunity for you to show me how I really am in need of mentoring regarding my turning skills (?) Could you forward a registration certificate for a course in the summer of 2024? Roger…from Pebble Beach, California. Thanks…you and your Channel (and photographer) give me great joy!

Awesome machine. Could you use a unidirectional pin/cam jam rather than a screw? Lise was definitely laughing. You really need to consider a “cricket box” protector - ideal height for pelvic area contact!!

Awesome machine! Also, very pleasing shape to the rough bowls. I've seen many times a very unpleasing shape after using a regular coring system.

Love to see homemade tools. I'm using a late 1800s wood lathe from my family's winery and cider mill operation that ended after prohibition in the late 1930s. It was used for many wooden spindles for the mill's operation. Back then, everything was made from wood. It has a 14" swing and can turn a spindle up to 8 feet long. I added a treadmill motor & all the controls so I could get variable speed, reverse, etc. I've been making many bowls and also use the Oneway coring system. I use the exact same cutter you use and I'm too cheap to buy the expensive holder sold by Hunter Tool Systems. It's hard to beat carbide especially when they cost about $1 USD. I can cut nearly 100 bowl cores with one cutter. I thought the Mastodon looked familiar. I've watched the coring videos from the Holland Mill and the Alaskan Mill. The one problem with these swing coring systems is that all the core shapes are very standard. I've thought about the McNaughton System but that looks like too much work. I sure would love to have a larger lathe. the Oneway 2036 or 2436 would be ideal. So glad I found this video. Awesome job with the build, the demo, and the explanation. Next up is to subscribe to your channel. I look forward to more videos about your woodturning. Regards, Greg

That is an amazing machine. The two of you did a great job building it, using inspiration is the way of the world and how we make progress. I wish I was nearby to buy some of the last cut small bowl blanks…. Thanks for the video. Canada. 🇨🇦 🇨🇦 🇨🇦

Awesome guys and Leis, ( I hope I spelled your name correctly)! That really appealed to the mad professor in me. I see the Mastodon as being a three way marriage of timber, steel, and ingenuity and I congratulate you guys on that from here in Australia where I’m just starting out wood turning. My first wood lathe I built myself and I was fortunate to escape with no injuries the first time I tried it out as it flew to pieces, jarring the bowl gouge from my grip and sending it spinning past my ear, ricocheting off the man cave wall and falling to the floor! The home made, and designed tool rest, landed on my foot, fortunately my work shoes prevented any damage. Ahh well! All part of being a mad professor, I guess.😅. I have since purchased a small second hand lathe.

Hallo Ronald ik leer een hoop van je video’s. De Mastadon heb ik op you tube ook met 3 messen gezien dus 3 schalen te gelijk draaien. Hoge productie dan. Eff. Aanpassen?

@elliottsimkins74 10 ай бұрын

The only problem I see, is that there is no way of attaching the bowl to the Oneway lathe! I guess you can use a glue block! I have a small coring machine, but it’s done in reverse! You have to put a tenon on the front, before you core the biggest piece, and then core the next larger piece!

Hi Elliot, I don't see the same problem. In this video I explain how I remount them on the lathe... kzbin.info/www/bejne/kInUiXiEjbOAq8U Is that the answer to your problem? or did you mean something else?

Wish I could talk to Jan about bowl/faceplate/knife geometry. Needs to remain proprietary info of course. I don't speak Dutch but have a 93 year old interpreter.

@JoelAllen-xj4cg Жыл бұрын

I wonder if the screw is part of the main spindle or part of faceplate?

@ronaldkanne Жыл бұрын

The screw is welded to the faceplate and the faceplate is screwed to the spindle...

I viewed your video with great interest and found it fascinating. Thank you. I do have two question: 1) In your video you mention that your cutter is a CCGT06 carbide insert from the metal machining world. Would you please let me know the complete identification code for the carbide insert which describes additional properties such as the hole, chip breaker, etc? 2) Is your carbide insert mounted such that it enters the wood at a negative rake angle so as to possibly reduce catches? If you use a negative rake angle, approximately what is the angle? My intent is to use carbide inserts on the McNaughton Center Saver knives. Looking forward to you response, Peter Toch, Virginia, USA

Ronald. Is it possible you can find a person who can make CAD drawings of this machine? I can pay for the services. Our Turning Club would love to own one like yours. KC

@ronaldkanne 2 жыл бұрын

I don't know anybody willing to do that KC. But it is not that difficult. Heavy machine with spindle. The thing to watch carefully is the design of the knives. They must have the exact same radius horizontally and verrically. And the pivot point of the knife must be in the middle of the spindle..

Do you think it would help to use wax on the mounting threads to make it easier to unscrew the remaining wood ?

@ronaldkanne 2 жыл бұрын

I don't think so Cecil. The remaining wood is pressed on the screw harder and harder every time i core a bowl... and i also need that friction for coring...
