Slightly off topic, but I'm always fascinated by watching this chaps work. ... . I wouldn't have thought work that fine could be done in Oak ... Amazed : MichaelG. He does bigger stuff too; I can remember him commenting on Facebook a while ago; He'd had a quote accepted, and the customer asked what CNC lathe he was using. When he said he did it all by eye, the customer cancelled the order as they wanted all the spindles to be the same. ( He's "The Woodturners" on Facebook if you want to follow his occasional videos.) |

Thanks, Bill ... but I am still resisting Facebook We did, however, watch the YouTube video of him hand-turning a pretty good sphere. ... Very impressed: MichaelG. |

I have found the Diamond Tool Cutter from Eccentric Engineering is excellent for turning wood, particularly if you use a round rather than a square tool. I have attached a couple of pictures showing the finish I got on the end grain of a piece of Kanuka wood. The finish is as good as that from a skew chisel but is of course dead flat. I use a similar cutter arrangement in my ball turner. There is very little sanding required after turning. |

Thanks to all. I've found what I needed at "AZCarbide", they have a range of inserts designed for/suitable for woodturning. Nathan. What did you buy and how much was the postage? |

[Can't seem to get out of quote mode!] Interesting points. It occurs to me that the tangential cutting action of the cutter in your ball turner is the same as that in J A Radford's design. Kanuka sounds as though it might come from NZ, too. |

Vic, at those prices I was never going to buy! I just wanted the range of shapes and am now looking for the full geometry of each insert. There must be a "near enough" Alan, that is also of interest, can you tell me if you modified from metal cutting angles to wood cutting angles? All good info and many thanks. Nathan

157 forum posts 26 photos | Hi ega, Yes, Kanuka is a bigger version of Manuka (as per the honey). Hi Nathan, The tool angle on the ball turner is the same as on the diamond tool holder and the tool was ground using the jig which came with the holder. I don't suppose it's surprising the setup works well with wood as it's similar to how a gouge is presented to the work on a woodworking lathe. The wood peels off the work without tearing, even on end grain which makes it ideal for ball turning. Regards, Alan |

![]() 7468 forum posts 230 photos | For turning wooden balls, get a bit of steel tube and make sure the cutting end is square and sharpen it like a leather punch with the taper on the outside, use this tool after you have roughed out the ball using the whole front edge to cut. To get a number of uniform sized balls, just make then the size of the bore of the tube, when the ball is to size it just pops into the tube. Turning wood in the metal lathe with metal turning tools, hard, fine grain wood is good(mature Rimu in NZ), just don't use soft new Radiata Pine, you'll have a real hard job even on a wood lathe with the sharpest tools.

Ian S C That looks like a pretty good way to do it - do you mean feed the tube-tool in square to the axis, from the side? I managed *sort of * OK with my hand-gouge on Zebrano for Saturn:- But sticking a caliper across it a few ways will expose its out-of-roundness pretty mercilessly... |

3453 forum posts 23 photos | Probably not viable if you’re only making one or two but ball turning jigs are available for wood turning Lathes and you get a perfect result every time, and much quicker. How long a piece of wood will stay that way is anyone guess though! |

To get a number of uniform sized balls, just make then the size of the bore of the tube, when the ball is to size it just pops into the tube. Good point. GHT covers this procedure in his Manual where he mentions that the method was used for turning billiard balls. That reminds me that there is a specialised trade in the manufacture and maintenance of cues; I wonder if they employ hand turning. |

2805 forum posts 219 photos | KWIL and Vic: Excellent video - thank you. My impression is that only the splice is planed; there was a shot of what looked like a lathe near the start. Some interesting similarities with metalworking: seasoning the stock and rolling on surface plate to check for straightness. |

3453 forum posts 23 photos | For some reason my earlier post has the wrong link. It should be this one. It clearly shows the hand planning process. Edited By Vic on 24/10/2018 17:59:12 |

![]() 1009 forum posts 305 photos | With tools held in a metal lathe the finish is not always too good as hand held woodturning tools you rub the bevel before cutting the wood so in effect are planing the wood. Ball are easy to do by hand if only doing small quantities as some of the jigs can be expensive. This was done free hand and is near as possible a perfect sphere it did require the sharpening of the tool quite a bit as ply knocks off the edge very quick. The sphere is 4" diameter. This came third in the last woodworking show at Alexander palace some years ago |
