Jerry,

It is a McNaughton Centre Saver. This is the first generation model that is about 15 years old now. I bought it from one of my club's former members who had not used it much and is scaling down his wood turning now. Here is a link to a video by one of your countrymen on the subject-

This shows one of the newer generations. I have only used it about 5 times and am always a bit nervous about where the end of the cutter is. Good operators can get multiple cores out but I think I am going well if I can just get the extra one, particularly in gnarly Ausralian hardwood like this blackbutt. (Eucalyptus pilularis)

Cheers,

Steve

Steve, a 520mm core is a good effort in anyone's money, especially if it's in something as tough as our hardwoods.

On the unwinding problem you get with large diameter pieces; if you have variable speed lathe you can dial it down slowly before you hit the stop button, but in your case without VS to slowly reduce the speed the piece will want to keep going when you hit the stop button and take a wander across the workshop. Locking the insert into the chuck doesn't prevent that. I found a rubber washer (made from tyre tubing) between the insert and the spindle shoulder reduced, but did not eliminate, the frequency of those 'moments of excitement'.

Jerry, I should have mentioned that when I told my wife of my new acquisition and that I would be able to get 2 or perhaps even 3 bowls from one blank her response was: "Does that mean that it is going to take 2 or 3 times as long to get through those piles of wood that are around the place?"

Cheers,

Steve, no need to send pictures of what your wife is describing, as I'm pretty sure it looks like my place. Hehehehe Miy wife asked the same thing.

I have a McNaughton center saver loaned to me by the local Woodcraft store here in Tucson. I asked about yours as it looks like the gate is not shown. Or is this the complete system?

I call it the Dictator as you have to follow the shape you end up with after coring.

I've started leaving my blanks straight on the sides, and start my coring about 1" down from the top edge. After cutting it off, I do the same on the next piece. If I'm lucky and planned it right and have enough material, I'll do another and then finish the last bowl still in the jaws. When done, I will have 3-4 bowls all the same OD. If I really knew what I was doing and could get larger blanks, I could get about 6 bowls from a 9" thick piece with the way I do it. I don't sell my stuff, so they just stack up. My table is shrinking.......

The way you started yours, your bowl diameters get smaller as you progress through. I tried that and failed miserably.................. Jerry (in Tucson)

Classic

Jerry,

As I mentioned it is a first generation McNaughton centre saver, pictures below showing complete unit. As you can see the support that fits into the banjo is not as solid as the newer ones. Also you will see that the cutting blade only has the tip forged out on one side for clearance. According to Robohippie in his YouTube clip the new ones with a solid support and clearance on both sides of the blade are superior.

However when I did my first large bank at my club they have a second generation unit and I tried it and gave it away as it was almost impossible to get started in the blackbutt. I reverted to my old version and while it still became stuck from time to time performed much better than the club's. I am working on a YouTube clip of my own so will let you know when it is up.

I had not thought of using your technique as I figure I can just cut thinner blanks with the chainsaw, but not as thin as yours obviously.

I sell most of my bowls at the local markets which is also a test of the quality and more importantly when I finished full time work last year and indicated to my wife that I would be able to do more turning she promptly said that I had better find an outlet as we could not afford to fill the house up. Having spend most of the last 29 years in inventory management I could not argue with her.

Cheers,

Steve

I rang him in SA at the Durden number that I do not have. Drillit.

Any joy on the bowl turning attachment and if so can I afford it?

Thanks
