Newbie ? Rolling beads
Greetings- I am turning some table legs of dry walnut
about 1 -1/2 in Dia. I have read Raffin's book, watched his video, and practiced for a day or two. When it comes to tuning beads about 1/4 wide I use a 1/2" skew chisel with the point down and have pretty good success. However, when I attempt it with the point up the tool skates down the work. Is there a cure for this? Perhaps the tool has to be perfectly perpendicualr to the axis? Or, do I have to cut a small groove to contain the tool edge? Thanks, Jim Oh, I hold my hand over the tool blade and hold it securely to the tool rest. |

Saw a comment in one of my new books that a common "new turner" mistake
is "insufficient forward thrust" when turning beads. Since I just had a few accidents in the last two hours and tried the advice -- I now think it might be true. ROTFL. Why do we never trust expert advice till we wreck something eh? So, starting with the skew at a 45 deg. angle -- tip pointing up and to your left -- forward thrust as you roll to the right -- with the skew ending up vertical and the centre of the edge NOT below the centre line of the turned piece. AT least that's what just worked. :-) I could scan and post that one page on my web site if it would help... But probably someone who knows what they are doing could help more...

Thanks Will, I will try it as soon as the Doctors office opens. Jim

There are several ways of rolling beads which do not use a skew.
A 3/8" beading and parting tool is the tool of choice for many of the UK turners. I've watched Martin Pidgen who turns thousands of lamp pulls a year with thousands of beads use it and decided to try it myself. That is the way I do it now. The French use a Bedan. I've tried this also but find it somewhat awkward. On the other hand, I've never had the chance to watch it being used up close as with Martin. The skew is hard to use -- maybe it is the wrong tool for the job? Bill Jim L. wrote: Thanks Will, I will try it as soon as the Doctors office opens. Jim "Will" wrote in message ...

Jim, if you are new to rolling beads with a scew you might consider
putting a dead cup center in the headstock rather than a prong center , that way the work can slip if you get a catch. tom |

"Will" wrote in message ... Saw a comment in one of my new books that a common "new turner" mistake is "insufficient forward thrust" when turning beads. Best way of describing it I've heard. Since moving downward faster than forward with a skew chisel puts the upper portion in contact with the piece, that causes the skate. However I have to say that I think the skew, a wonderful tool for running planing cuts, is not the tool for beading. Bill mentions a couple of options - beading tool, which is a double-bevel straight chisel, and a Bedan, which is a single bevel. Super options. Beading tools generally have to be made at home, though. Other option some use is grinding the skew into a convex profile, so you can lag farther behind in forward thrust without the relieved upper edge engaging the work. |

I found the Two Books in one By Phil Irons has a reference to using a
Spindle Gouge (3/8 inch?).... Page 58-59 in Techniques. -- start reference -- Quote... (Paraphrase actually) Hold the bevel against the work and slowly raise the handle while rotating to the right. The tool should finish with the flute facing away from the bead. Do the cutting with the right hand half of the edge and finish up with the tip against the wood. .... Reverse steps for left hand edge... I have the Darlow book, Fundamentals of Woodturning as well - beads are cut using the skew... Pages 84-99 Good explanations - takes practice as you can tell from my spindle - see below :-) -- end reference -- I was able to do them (sort of) with the skew... see here... http://woodwork.pmccl.com/Business/p...urnedwood.html But it was troublesome for rusty skills. Think I will fall in love with a spindle gouge. :-) ... and reserve my skew for smoothing. Bill Rubenstein wrote: There are several ways of rolling beads which do not use a skew.

I recommend beginners start their skew work with larger beads of at least one inch diameter. The reason is that when you roll a bead with the skew, the bevel has to swing through close to 90 degrees and the handle has to make a correspondingly large movement. The difficulty comes when this large swing has to be coordinated with a small forward movement in a small bead. It is much easier to get the swing right if it can be done over a longer curve. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com http://chipshop.blogspot.com http://groups.yahoo.com/group/toolrest/ |

Nice web site Derek. Like the turnings you have posted. Interesting bowls.
I think there must be something about the east cost that causes wood turning. Is it a virus or a congenital condition out there? (Probably can't be cured -- eh?) Yeah -- I had that feeling when I was turning the spindle on my web page. Even the small skew just didn't work for the fine stuff - so I will take your advice to heart. It was definitely easier on the left side (of the spindle) with the skew.

Here's another idea if you promise not to tell...
When turning very small beads (such as on the handle of a top) I use a 1/8" plain parting tool -- not a diamond shaped one. I use a corner, roll the tool as if it were a skew and it works just fine. When making tops from one piece of wood, I reduce the thickness for the handle with peeling cuts with the parting tool, it is already in my hand, so... I also have two round skews, a 1/4" and a 3/8" which were home-made from drill rod. These are used more to make small v cuts than for beads. Bill Will wrote: Nice web site Derek.

Thanks to all for the information. I tried using my 1/2 inch spindle gouge
and it worked fine. I again tried the double bevel skew tool with the cutting edge down and it scares hell out of me so I will abandon that until some mentor gives me a demo. I will fabricate some of the other suggested tool shapes. Again, thanks, Jim. "Jim L." wrote in message ... Greetings- I am turning some table legs of dry walnut about 1 -1/2 in Dia.

I'll bet you a nickle to nothing that you will always come back to the spindle gouge for beads, once you have got the hang of it. Bjarte |

Just very small. :-) I will try this ADRSN (any day real soon now) -- Like next time I put a spindle on. It's more like a bedan than a skew, only not so wide. The sharpening angle is much greater than a skew, and the cutting edge isn't skewed. Because of the larger sharpening angle you won't be able to get such a full bead if it is adjacent to another bead or some other feature. It will be fine if the bead is standing proud of the surrounding wood, but not if it is to be inset. The other thing to consider is that you are using the corner of the tool to make the cut. Now, there are two ways to cut a bead with the skew. One is with the edge, typically about one third of the way along the edge from the short point (heel). The other method is to cut on the short point itself, which is more akin to the cutting action of the bedan. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com http://chipshop.blogspot.com http://groups.yahoo.com/group/toolrest/ |
