Skew problems
I'm still having difficulty with skew chisels. I seem to get far too many
catches, despite being very careful and keeping the bevel rubbing whenever possible. I've even taken to honing them after sharpening. My question: my skews are fairly short and light in weight. Could this be a problem? Would longer, heavier skews improve my chances of not catching, or simply make the catches more painful? Any suggestions will be appreciated. Thanks, Max |

Our club chairman suggested that I start using the skew as much as possible, particularly for things like roughing and gross shaping. There seems to be a special kind of nervousness that goes with the critical finishing cuts, that makes the skew more treacherous. You will not be good with the skew are able to relax--until you are able to concentrate on the shape, letting your "muscle memory" take care of the mechanical part. It's a lot like learning to drive, or play music. |

Skew problems
you might want to try Alan Lacer's video The skew, the dark side the
sweet side. He goes into allot of things that may help. I like the dead center as a driver. You can slip the work depending on how tight you make the tail stock. If you can grab the work a catch is not going to be that bad. Bruce Maxprop wrote: I'm still having difficulty with skew chisels.

Skew problems
Max, I was having terrible catches with the skew when I first started turning. An experienced woodturner watched me turn and looked at my skew, and said it was not sharp. This does not seem to be your problem. Another problem I was having was the top and bottom of my skew was digging into the wood as I tried to use it. He suggested I grind back those spots, I did that and have had no more problems. Since then (5 years ago) I have bought a new skew and now use it without grinding down the edges. The skew is one of the tools I use the most now. I use heavy and light skews for different jobs, but the heavy ones the most often. Glenn Nashville, GA |

There is some good advice above. Also make sure you are cutting down
hill - meaning do not cut into the end-grain, instead cut away from the end grain. Even with great technique, you can get catches if you cut into the grain. I learned the skew from a Brian Clifford article he has on the web. I do not have the link at hand, but you cn find it on the links page on my web site. Brad HardingPens.com |

Skew problems (this long post may add to the problem)
Hi Max, I think one problem occurs when cutting a straight shoulder or
coved surface with a flat straight edged tool (skew) applied nearly perpendicular to the turning axis. The more perpendicular the cut the less edge contact and less bevel rubbing the wood's surface is allowed before the tool skids into a spiral or the point digs in. When truly perpendicular only the skew's point is allowed. Solution: When skewing at wide angles to the axis, keep most of the edge and all of the bevel off the wood. ie. stay on the point. Another problem occurs when a flat edged tool is moved parallel to the turning axis. Here the bevel and the edge between the points isn't the enemy; it's the points that cause the trouble so keep them away from the wood by keeping the edge-wood contact area small and well between the skew's points. Also keep the shaft-toolrest contact area firmly & directly below the edge-wood contact area and don't wave the skew about. Peeling is another skewing action, but it doesn't seem to be a problem. *********************************************** Now forget all the above, you don't learn to skew by reading and it may or may not be true anyway. Like learning to canoe by deliberately upsetting and falling out, one way to learn how to skew wood is to make many deliberate skids & digs (try the opposite of above advice) on soft timber at slow speed with a devil may care attitude yet observing what happened. Keep on & on until like upsetting a canoe, the fear is gone, skewing is second nature and it takes an effort to make a deliberate mistake. In keeping with my obvious tendency toward brief posts, I'll add an analogy. Once I had to train some prim volunteers to do VD interviews. To desensitize them to fear & embarrassment, I had them look at pornographic movies all day long for two days. They soon became inured, very bored and fell asleep.

I taught myself to use the skew w/o fear by using the only skew I had at the time, a 1/2" Sorby mini tool, to reduce pieces of 8" diameter firewood to shavings, over and over again, from rough to finish. It's really just a matter of getting comfortable with where to hold the tool, how to hold the tool and what you can and can't ask of it.

Simply put, the bevel on one side, the other flat. For the same reason that a bevel chisel digs in when you use the flat side down, a skew will do the same. Also better to use a beading tool - narrow straight chisel - for cutting beads, in my experience. Saves you from yourself, and the tendency to cut only inward, forgetting that there comes a point (no pun intended) where the projecting part grabs and throws you out as it catches what you had not cut down upon. |

Would longer, heavier skews improve my chances of not catching, or simply make the catches more painful? Any suggestions will be appreciated. This is a really difficult problem to diagnose at a distance. But 'whenever possible' is not good enough. I can think of very few instances when the skew is safely used without bevel support. The most likely tool size issue is the width of the blade. Assuming that you are talking about cutting with the edge rather than either of the points, a blade which is too narrow will make it difficult to keep the cut away from the point. Larger diameter work (ie the surface is much flatter than small diameter work) calls for a larger tool. FWIW I do nearly all my work with a 3/4" oval skew. Standing in the right place before starting to roll a bead is very important. Before you turn the lathe on, make a few pretend cuts, making sure that you can comfortably move the tool from its starting position with the bevel parallel to the lathe axis, to its finishing position with the tool handle perpendicular to the lathe axis. A common problem for novices is to stand in a comfortable position to start the cut, but then quickly find they are off balance by the time the skew is cutting into endgrain. It is at this point that the wood requires more force to cut, and the turner looses control. Wrist action is important too. You need to be able to roll the tool comfortably through 90 degrees. I hold the tool handle with the thumb along the handle and in line with the top of the blade. I find this puts my hand in a comfortable and controlled position throughout the cut. Another common problem is trying to cut beads which are too small. The problem here is that the skew still needs to swing and rotate through the same wide arc, but on a small bead it has to do so over very little forward movement. This requires considerable coordination. I normally start students on beads about 1 inch diameter, and certainly between 1/2" and 1 1/2" diameter. Practice in softwood to begin with where the forces involved are less. I find 2x4 spruce studs to be good, ripped up into square stock and just using pieces that are straight grained and knot free. Beware of anything that suddenly changes the forces on the cutting edge. Most common is letting the cut move from the cutting edge to the point. While a bead can be cut in either position, the way the cut is made and the forces on the tool are quite different. Switching from one to the other part way through a cut is a recipe for disaster, though it can be done with care. Other common problems like this are allowing the depth of cut to get too big, or not being ready for the extra force required to cut through the endgrain. If you loose the cut part way through a bead, take care. Do not drag the cutting edge back up the cut surface as this will cause a catch if the edge contacts the wood without bevel support. Until you are very familiar with the tool, I recommend consciously removing the tool from the wood, then rubbing the bevel and carefully reintroducing the cutting edge just behind where you left off. If at anytime the cutting edge contacts the wood without bevel support and the turner having full control of the tool, then a catch is almost certain. Those are most of the common problems I see with beginners. If you can be more specific about the problem, like exactly what you are trying to do, and the conditions under which the catch occurs, please provide more information and I will try to help. Hands on instruction is a much more effective solution though. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com http://chipshop.blogspot.com - a blog for my customers http://www.seafoamwoodturning.com/TheToolrest/ - a blog for woodturners |

Skew problems
If you are having problems using skew chisels.......that probably just means
you are fairly normal in motor skill development, likely well-adjusted and happy in most other aspects of your life.......and much like a whole lot of other woodturners. I'm certainly no expert with the skew, myself. Personally, I find that larger (longer cutting edge) skews, say the 1" size or larger, are usually less prone to catches. I like the heavier traditional skews (rectangular cross section) rather than the newer and lighter weight oval skews. I doubt the length of your skew chisels has any bearing on their propensity for "catches". Watch you cut and make sure you are doing the cutting with the lower one-third of the cutting edge. There is a DVD by Alan Lacer, entitled "The Skew Chisel" that you might find useful. Watch the DVD, then find some cheap wood and practice, practice, practice. If that doesn't help, avoidance might. If you switch to turning bowls and hollow vessels, you'll rarely have need for a skew chisel. Good luck. Barry "Maxprop" wrote in message link.net... I'm still having difficulty with skew chisels.

I feel very fortunate to have access to such a talented and experienced group of turners all in one place. Throughout your answers I detected more than a few mistakes I've been making, and I've just spent several hours implementing quite a bit of the advice given. I ripped four 16" sections of 2x4s and turned all eight 2x2 sections into shavings and dust, and I'm happy to report that toward the end the catches were few and far between. Progress is being made, thanks to you folks. Please give yourselves a pat on the back from me--you deserve it. And my wife is grateful to hear less epithet-laden language emanating from the basement. Alan Lacer's DVD is my next purchase, as is a Stebcenter drive center and a 3/4" skew. I hope to have this problem licked soon. Thanks again, Max |

Skew problems
Hi Max, Glad you have skewered the epithets.
I agree with the Lacer CD and 3/4" skew, but why do you need a Steb center? I've read the ads, but I've never used one as it seems to me to be an expensive device that like a cheaper dead center tends to perpetuate instead of improve poor tool work and it fills some other needs that most hobbyists don't have. Other's opinions will differ and I'm willing to learn. Turn to Safety, Arch Fortiter http://community.webtv.net/almcc/MacsMusings |

But I was hoping a Stebcenter might be a good device to use while learning the taming of the skew (sorry). I don't own a dead center--my lathe came only with a live one plus some drive centers--so I shopped for a center that would allow slippage, but couldn't find a dead center offered. At least the Craft Supplies catalog doesn't seem to have them. I'm sure they've got to be cheaper than a Stebcenter, so I'm all ears if you think they'll work as well for less money. As for poor tool work, I believe that is my middle name, but I'm improving. Max |

Skew problems
Max, instead of using a skew, use a round nose scraper, freshly sharpened,
tilted up at about a 45 degree angle, with the bevel rubbing. Guess what? It cuts well, will not catch. However, it really doesn't work well for long straight sections, as the handle is at a 60-75 degree angle to the surface. But for plankwise open bowls, it is great to do the last pass (inside and out) to leave a very clean cut. Try it, you will like it!! James Johnson "Maxprop" wrote in message link.net...

If you take the bevel back even farther, you can get more to guide on what is surely an extreme Lacer grind. |

James Johnson I have a heavy (1/2" thick) round-nose scraper which should work well, but I'm unsure as to how to use via your method to cut beads and coves. It does, however, leave a very smooth, chatter-free surface on bowls, as you've implied. Max |

Skew problems
Max, another forgiving tool for smoothing a spindle surface can be made
by removing the bevel and grinding a new one on the flute side of a shallow 3/4" or larger gouge. Held upside down & flat on the rest and pulled at an angle, the wings prevent rotation and 'slam-downs' while the fixed tangent of curved gouge to curved wood helps control the chip width and 'dig-ins'. Find the sweet-angle and it works quite well. If you have an unused old carbon steel gouge you may want to try it. Not condescending to you, but a true beginner should remember to use a dead _ring_ center, not a dead 60deg. center as a clutch. Maybe I've forgotten how to 'double clutch' , but a dead ring center drive is a pain to me. It either slips too easily or it needs too much tailstock pressure.

It's the special alloys and tool steels that cost a lot of money- but the carbon steel ones have thier place as well (They take an edge like nothing else, it just doesn't stay keen as long, and is prone to rusting) |

Amazingly they aren't all that bad, but I doubt if the steel is M2. They hold an edge reasonably well, and I don't worry about ruining them while trying different grinds on the Wolverine jig. In fact, I've taken my 3/4" skew and put a Lacer-type gentle radius on it. That certainly made it more user-friendly--I have yet to get a catch with it after altering the edge profile. I also want to report that since implementing some of the suggestions made by those who responded to my original plea for help, I'm now enjoying my skews tremendously, having almost no catches, and definitely getting better results. Thanks to everyone who contributed. Max |

I'm not sure I need one any longer--spent my spare time the past two days turning pine 2x2s and so far nary a catch. In fact, I'm discovering just how much fun a skew can be when used properly. I'm still not rolling nice beads yet, but my surface quality has improved 100%. Thanks to the help from posters here (and some time spent with one of Raffan's books), my learning curve is steepening.

... In fact, I'm
discovering just how much fun a skew can be when used properly. I'm still not rolling nice beads yet, but my surface quality has improved 100%. Thanks to the help from posters here (and some time spent with one of Raffan's books), my learning curve is steepening. Glad to hear that you are making progress! Several things will help with improving the form of the shapes you create. First is the ability to look at the shape you make and identify exactly what is wrong with it. This is quite a skill in itself so don't be afraid to spend time taking a good long look at your work. A piece of black card held behind the work can help you to see the profile more clearly, but it is still up to you to decide what is good and bad about it, and what wood you can remove to correct it. Many novices have trouble deciding where to start cutting. Always remember that you can only remove so much wood with a single cut. To turn a square profile in to a circle, start at the corners with a small cut and work towards your goal by making successive cuts parallel to the desired result. Another approach is to take the corners off to create an octagonal profile, then take a little off of each of the resulting corners. This can be done very quickly with the short point of the skew. When you are close to a circle you can make one fine cut all the way around to leave a nice circle. All the time of course you need to be watching the shape you are creating. Remember that with a subtractive process like woodturning, once you have cut a piece of wood off, you can't put it back on You can either stop and look at the profile after each cut, or you can take your eyes off the tool and watch the profile as you cut. This latter approach has the benefit of teaching you turn by feel, a very important skill which requires considerable empathy with the tools and the wood. Keep at. Your perseverance will pay off. -- Derek Andrews, woodturner http://www.seafoamwoodturning.com http://chipshop.blogspot.com - a blog for my customers http://www.seafoamwoodturning.com/TheToolrest/ - a blog for woodturners |

Skew problems
"Derek Andrews" wrote in message ... ... In fact, I'm discovering just how much fun a skew can be when used properly. I'm still not rolling nice beads yet, but my surface quality has improved 100%. Thanks to the help from posters here (and some time spent with one of Raffan's books), my learning curve is steepening. Glad to hear that you are making progress! Several things will help with improving the form of the shapes you create. First is the ability to look at the shape you make and identify exactly what is wrong with it. This is quite a skill in itself so don't be afraid to spend time taking a good long look at your work. A piece of black card held behind the work can help you to see the profile more clearly, but it is still up to you to decide what is good and bad about it, and what wood you can remove to correct it. Many novices have trouble deciding where to start cutting. Always remember that you can only remove so much wood with a single cut. To turn a square profile in to a circle, start at the corners with a small cut and work towards your goal by making successive cuts parallel to the desired result. Another approach is to take the corners off to create an octagonal profile, then take a little off of each of the resulting corners. This can be done very quickly with the short point of the skew. When you are close to a circle you can make one fine cut all the way around to leave a nice circle. All the time of course you need to be watching the shape you are creating. Remember that with a subtractive process like woodturning, once you have cut a piece of wood off, you can't put it back on You can either stop and look at the profile after each cut, or you can take your eyes off the tool and watch the profile as you cut. This latter approach has the benefit of teaching you turn by feel, a very important skill which requires considerable empathy with the tools and the wood. Keep at. Your perseverance will pay off. My problem is with small, narrow beads, not the larger ones. I seem to be able to make wider curves, but the tiny two or three part beads, like those decorating bowl rims, etc., are the ones I can't seem to create well. They are harder to visualize, but that doesn't seem to be an issue. What is a problem is my ability to roll the skew smoothly to round a, say, 1mm bead. I'm wondering if a skew with rolled edges might help. I can actually do slightly better with a fine detail gouge, but I'd really like to get these things down with a skew. I guess I'm just pedantic enough to want to be competent with every tool. Thanks for the advice, Derek. Max |

More clearance in narrow quarters, no nose to catch with the beading, and all plane real well. Don't have to buy one, as you probably have a couple cheap scrapers you can convert. The best tool for any job is the one that does it best in your hands. |

The best tool for any job is the one that does it best in your hands. Funny, but after posting my last response to Derek, I chatted with a friend in California--a long-term woodturner--who said the same thing--"use a beading tool, fer cryin' out loud." After almost 30 years of turning, he claims he still cannot make decent mini-beads with a skew. I guess I shouldn't feel so bad. I do have some cheap scrapers, including one narrow one I never use, that I'll try to convert. Now I face the problem of being able to make a nice set of half-coves on the tool with a small ledge in between. OR, Robert Sorby has one for not too awfully much money, if I fail. Max |

I am confused. to me a beading, or rather beading/parting tool, is a square or rectangular tool used either as a parting or as a beading tool. The idea is to use the narrow edge of your tool in a similar manner to a skew. For instance, you wish to turn those 1mm beads on the edge of the bowl, as you were discussing . Use the point formed by the conjunction of the two sides of the parting tool to make a v cut leaving your 1mm ridge. Round the ridge with the point formed by that conjunction in a similar manner to a skew. However, in this case the skew is 1/8" wide and much easier to maneuver. Those other beading tools are dedicated scrapers and likely work well but this is more versatile. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |

What is often called a "beading tool" today is a scraper. The tool traditionally referred to a beading tool was a chisel with a fairly long bevel. Provides clearance on the non-bevel side to keep down those annoying heel bruises caused by impacting the bevel on the opposite side. As I posted earlier in this thread, skews used to come in left and right flavors too. That way as you went to a steeper angle to cut and begin the peel, you weren't butting up against the opposite bevel. Think of it as a low-angle plane. I'll pop a picture of mine and put it up tomorrow if the bright sunshine calling me outside doesn't get in the way. |

Actually, to turn a bead on a bowl I would use a three point tool which only
has one point but three cutting edges. Why is the darned thing not called a pyramid tool? Whichever the name, it cuts well and is great for this application. By the way, to grind a radius into a scraper, mount a drill based grinding wheel into your drill press, radius the edge with a grinding wheel dresser, rig a table to stabilize the tool being presented, and grind the radius. Do not make it complicated. -- God bless and safe turning Darrell Feltmate Truro, NS Canada www.aroundthewoods.com |

Tiny beads are really hard. I made a special tool out of a very small
1/4" square shaft spindle gouge which I rarely if ever used...re-ground it so it now makes perfect beads as a scraper with a U shaped grind. |

Do you really mean 1mm? I could hardly see a bead that small, let alone turn one! I saw a local turner's works last summer, and several of his pieces had lovely tiny beads decorating the rims or occasionally on the throat of a hollow form vase. I should have asked him how he did them. They seemed to be around 1mm in size, but measured from valley to valley, I suspect they were larger. As you say 1mm is really small. As for decorating a bowl rim, I would use a spindle gouge every time. I wouldn't go near a bowl with a skew chisel. Probably good advice for me, especially since I'm not that adept yet with a skew. And while on the subject, will a skew cut endgrain smoothly? I've never tried. I keep a small spindle gouge for turning small beads, both on spindles and bowls. It has a very long side grind and an acute sharpening angle. This allows it to make a quite narrow V-groove between adjacent beads to cast a deep shadow and give a nice crisp look. But if you are getting anywhere near being able to turn a 1 mm bead with a skew, keep at it. I would say that you are truly pushing your skill level and will make a great turner. I'm far from there at this point, but it would be nice to be able to do some finer detail work that might help distinguish my work in the future. I have a small detail gouge with which I'm getting better. I can do far better beads with it than with a skew. It's really a great little tool, and I'm sure I'll be inclined to use it instead of the skew if I'm doing some piece for keeps. Your advice is greatly appreciated, Derek. Max |
