McNaughton Centre Saver bowl coring system: demonstration by novice user

Demonstration of the McNaughton Centre Saver system; not a tutorial or instructional video, but an insight into the system in the hands of a novice user. My only training was watching the DVD by Mike Mahoney, which I purchased at the same time.
There are several coring systems on the market, and people often have questions about the McNaughton (usually around it being more 'free-hand', but in turn perhaps more versatile, than other coring systems). So this video is intentionally filmed in real-time and first take with no edits to give an honest overview of how the system works in the hands of a user with no training. The video shows only the third time coring a bowl; happy to say each attempt has been successful.
The lathe is a Union Graduate 'Short Bed', running a 1.5hp six-pole three-phase motor on VFD inverter. Blank is being held on a 110mm male tenon, held in 'Gripper' jaws of an Axminster 'Evolution' SK114 scroll chuck.
Important note: the McNaughton system requires minimum 74mm between top of banjo and centre height; the Graduate doesn't allow this as standard. To get round this, I cut a section from the top of the banjo. If you want any details of what I did (as it involves permanently modifying your machine) please feel free to ask in comments.

nice first try thanks for posting

[@yealife2947]

That was a very good first effort indeed.

Hi that’s a great bit of kit you have their ….do you need that type of bed for turning large bowls using a chuck or will the other type work.

[@longdriver2]

Every time I use this system I look at the bowl bottom wondering if I went too deep!

[@conzi119]

nice union graduate lathe

[@robohippy]

Well, by now, I would think that this core would take you maybe 5 minutes.... I do use a collar around the tool rest post so I don't have to fiddle to get the correct height every time, just put the tool rest in and go...

Great video! Could You tell me where You get 1.5hp six-pole 3ph motor? I got answer from Newton-tesla that 6-pole motor would not fit ..could You clarify this ?? Thanks in advance for help i want to buy motor and vfd asap!

[@mysticbravo]

Apologies for delay in replying. My motor + VFD/inverter was custom built by Haydock Converters in Blackburn, Lancashire. They know Graduate and many other lathes inside out, so will be able to advise. Hope this helps.

[@peterch6909]

Thanks i already got 2hp 4 pole motor i just lost one pulley on motor . I am building bed and tailstock( 4 morse taper) on my own . Thanks for Reply!!!

[@peterch6909]

Please share info this is really important for me :)

[@crackerjack3359]

Nice. Wach your fingers though. That thing will flatten them if they get caught.

[@NativeEarthlingAI]

So tentative

[@kc696969]

I do this for a living. I would have hogged out the inside in less than two minutes. time is money. this is not rare wood. Good effort, but waste of time. Also, I would never core into a bowl with screws in the face plate like this. You never know where the end of that cutter is.

[@williamswhistlepipes]

But surely the whole point is making as many bowls as you can out of one piece. Blanks of any type are expensive and cutting and seasoning the takes time. I agree the face plate should not be on
