I need a little assistance. I've read reviews on the Delta 23-700 on
Amazon, I've read about the Woodcraft horizontal WetStone grinder, I've slobbered over the Tormek although I don't know why, I've looked at a few other Delta models, a Jet model, I've read and researched old threads on Google as to this subject. Basically I need to sharpen my turning tools. I've been turning for a week now and needless to say I'm hooked. I'm making plans to create all of my Christmas gifts on the lathe, but I know I'll be doing a lot of sharpening as well. So the question becomes, what do I get? A horizontal wet stone, a bench grinder, a slow speed grinder, jigs to hold the tools (I think this is a must). I had a guy at the local woodcraft recommend a 1" belt sander with fine belts. Really? I talked to him about the various choices but he wasn't much help. I do know I'll need to get some different wheels of varying grit. I do all kinds of woodworking, I'd prefer something I can sharpen my chisels and jointer knives on as well. Thanks in advance for any and all advice. -- Mike |

There's grinding, which reshapes your tool, sharpening, which creates an
edge, and honing, which refines what a lot of turners consider a "good enough." Belt sanders can handle all three, with appropriate belts, but are not kind to carbon steels found in chisels, planes and so forth. High speed grinders suffer from a bit of the same problem. A coarse wheel and a careless hand can take a big chunk off of a chisel quickly. Some tradeoff is possible with the "friable" soft bond grinding wheels, where the wheel disappears faster than the steel. So, if you're going to have just one to do everything, I think it's tough to beat a low-speed setup, which grinds your mower blades with cheap stones, your plane irons and turning tools with more expensive, but still not ridiculously soft, and your carving tools with the softest. You can have both speeds if you get a good mandrel and two pulleys for your motor, but I'm betting you'll stick with slow. Wet or dry? If you think having water around in the shop all the time is fine, get one. I don't, but I still hone my flat edges on the Makita, which does a superb job. Just remember to drain it before you spill it. As far as jigs go, they give you a repeatable grind, which, if you like to tailor your turning style to your tools, is fine. I have a large number of tools acquired over the years, and they are ground at many angles which allow me many options in the way I cut. The jig is the bevel, which I sharpen as if I were turning, laying the tool on the rest, the heel on the slow stone, and moving the handle until contact is made on the entire bevel, then following it as if I were taking a cut on the lathe. I don't normally hone turning tools, but when I do, it's with diamond slips/stones which can be used dry. "Mike Rinken" wrote in message news:LhO3d.473885$%_6.207928@attbi_s01...

I agree with Peter. I have a high speed 8" grinder and a Woodcraft 8" slow
speed plus a Tormek. The Tormek never gets used with the turning tools. Too much prep and maintenance, plus too slow. In fact, I use the high speed grinder the most because I haven't ever moved my Wolverine setup over to it. I have a couple of homemade setups on the slow speed that mimic some of the Wolverine, but are harder to adjust. So they are fixed for certain grinds. Very fast to sharpen my tools, just turn around from the lathe, flick the switch, tool on the wheel, switch off, back to turning. No water container to clean and keep refilled. Tormek is very nice for an extremely sharp edge, but that's not the most important thing in woodturning. -- Rusty Myers Austin, TX "Peter Teubel" wrote in message ...

Kingspor has a grinder that runs 1720 rpm's with white wheels, one 60 grit
and the other 120. With the Wolverine system that is all you will ever need. Tim "Mike Rinken" wrote in message news:LhO3d.473885$%_6.207928@attbi_s01... I need a little assistance.

And I agree with Rusty. Get a high-speed grinder (I use a 7" Baldor) and the Oneway jig
system. Then have someone show you how to use them -- it will save you a lot of time and steel. The slow speed grinder may help at first but as you get better at using it it will become a frustration -- too slow -- and you will not grind when you really should. Also, for your primary bowl gouges, I like a removable handle which comes off easily. That allows me to turn with a very heavy tool, remove the handle quickly, and grind with just the light gouge so that I can get the feel of what I'm doing. Tormek is a waste of money for turners, I think. The Oneway balancing kit is a really nice- to-have also. Another thing, don't buy wheels which are too fine. For most of us, 100 grit is plenty fine. I use a 36 on one side and an 80 on the other. Buy white wheels as a minimum. There are some premium blue wheels which are also very nice to have. Bill In article , says... I agree with Peter.

Ditto to Bill and Rusty.
I uesed a Delta vertical wet wheel for about a year for all my sharpening. I then took a class from John Jordan who showed me the correct way to use a regular 3450 rpm grinder. I bought an 8" JET the next week and a Wolverine system. I drained the pond on the wet wheel and shelved it. I never looked back. The additional benefit for having the fast wheel is that if you ever go to someone else's shop or do a club demo, you will be ready to grind in the most "difficult" situation - a fast, dry wheel. As for grinders, Baldor is the standard, but pricy. Deltas can work, but I've seen a number of them that vibrate excessively. You may end up returning them for another or buying a wheel balancing system. For what it is worth, my JET 8" is heavy-rock solid with no vibration. It cost about $175. The 8" Baldor approaches $500.

My personal feeling is that anybody selling a Tormek to a turner is either not a turner or
working on commission. It just isn't appropriate for us. Turning a 1' diameter form at 250 rpm and we are cutting 785'/minute. That glass-like edge may even last several seconds. I roughed out a sweet gum bowl(not my favorite wood but the log has been taking up space in my garage) and reground at least 6 times because it was quick and easy and I knew that the tool would cut better after it was ground.

I won't belabor folks with the details as anyone who wants them can find
them by searching on my name and Tormek, Sharpening, or Grinders. And in a couple of months you will be able to read an extensive comparative article discussing all the principle means of sharpening woodturning tools: HS grinder, LS grinder, Belt Sander, and Tormek. I have the choice of them all, use them all, and find a place for them all in the maintenance of my turning tools. I will just note that I am a woodturner,have been for a long time, am not on commission nor attempting to sell anything, but my findings based on critical experience with all the many sharpening methods is that the Tormek is one of the very best methods of maintaining the edge of ones turning tools, particularly gouges. I find it gives a meaningfully sharper edge than any tool used straight off a dry grinder, provides for more time between grindings, results in less steel being removed which of course leads to longer tool life, and is safe, easy and predictable to use. These are not just my findings, but are consistent with the many professional turners who have been very pleased with the Tormek (Steve Russell being a very good example of someone who very rigorously evaluates any tool that he puts to use and lauds the Tormek), or have long advocated that for anything other than roughing out, honing with a fine abrasive should follow dry grinding (Jerry Glaser, Alan Lacer, Rude Osolnick,Bob Stocksdale and Del Stubs is just a short list of the prominent). Some of the folks at the cutting edge of investigating sharpening techniques (Bill Tindall being a good example) have found the superiority of a finely honed edge for woodturning (he uses diamond slurries). So while folks have every right to be satisfied with whatever level of sharpness that meets their needs and sensibilities, a blanket statement that the Tormek or finely honed edges "just isn't appropriate for us" is simply not supported by the findings and practices of a substantial body of knowledgable and respected turners.

Sharp is as sharp does, Mike. Let your shavings guide you, not your
grinding jig. Tool presentation is the most important part of removing wood gracefully. 1) "Ride" the toolrest. 2) Meet the piece with the heel of the bevel. 3) Gain the cutting angle by moving the handle of the tool until the desired shaving is produced. The work should slide on the bevel, not the other way 'round, and a properly cut shaving should fall, not shoot away.

When good people who are good turners disagree re a technique, a tool
edge, a descriptive term, or blondes vs redheads, it probably means that there is no clearly superior answer no matter how tenaciously held or expertly promoted. Sometimes one size doesn't fit all; meaning that there is not a perfect single solution. Probably differing opinions depend upon personal attitudes and competencies. Politics and religion are probably unimportant in the pathogenesis of these important debates. Genetics, el nino and environmental conditions are iffy, but may occasionally play a small role. I have no hope that this helps to (en)lighten the load. ![]() Fortiter, http://community.webtv.net/almcc/MacsMusings |

Lyn,
I'll be anxious to read your comparative article. My experience with the Tormek puts it in the class of - "sharpens tools very well, maybe the best of the grinders out there" , but requires enough extra time using it to make it just a bit irritating!.( the motor start up even lags) I'm looking forward to your article.

Sharpening aids & jigs are certainly useful and are employed instead of

I have been using the Woverine Jig, and the Woodcraft 1750 speed grinder to
sharpen my turning gouges for about 4 years. Nashville, Ga. |

Or, more likely, there are multiple superior answers, but which one is superior for YOU depends on what YOU want. Me, for example, I got a Torkmek with all the accessories. Why would a woodturner want an axe sharpening jig? Because I own an axe, of course. Would all woodturners benefit from an axe sharpening jig? Of course not. But because of my situation and personal needs, the Tormek is the obviously correct choice for ME - I sharpen my own axes, chisels, planes, jointer and planer knives, scissors[1], and turning tools. I have time to put a fine edge on gouges when the job would benefit from it. I have no talent when it comes to free-handing on the grinder. So, a Tormek is perfect for me. My backup is a 6" high speed grinder for rough shaping. Would that be right for everyone? No, it wouldn't. On the other hand, a year ago at the Craftsmen's Fair, I brought my cheap 6" grinder - well tuned of course - for sharpening at our demo tent. One of the pros from the other tent would show up each day and zip zip zip hand sharpen his gouges for the day. A Tormek would be all wrong for him. Geesh! Didn't mean to start a huge discussion here but all great opinions. I've been a woodworker for about 8 years now and have never owned a grinder. I've always used other methods to sharpen my tools (chisels are sharpened using the scary sharp method) and figured it was time to add a grinder, but wanted to wait and see other uses for it until I did. Purchasing the lathe (which is a Jet Mini Lathe I got on Ebay for $80) drove me to make a decision, but with anything else I do before I buy I research. Someday I might end up getting a Tormek but at this point, I don't know if I'll be a serious or casual turner so the dual speed Woodcraft grinder seemed like the best decision. I did splurge on the Wolverine jig, which is specifically for the turning tools, nothing else I can think of. But once again the most (I believe) underused piece of the internet (usenet) comes through with flying colors. Thanks again to all for your advice and opinions. I'll be asking about chucks next! ![]() Mike |

You could do what I did - get the cheapest grinder you can find (probably a high speed 6") and a set of $32 chinese turning tools, and practice. You'll learn to have a LIGHT hand, which is what you need to keep the tools from losing their temper. Then, when you get frustrated and splurge on something with jigs and such, you won't feel so bad about spending all that money ;-) (and you'll still have a cheap grinder for rough jobs) |

Arch,
I agree that it is a skill to a point. There are people that can run sub 4 miles, but I will never get there despite years of training. In other words, I suppose there are people that have insufficient dexterity to successfully and repeatably freehand grind. I also think this number is very small. On the flip side, you can make terrible grinds with a jig too. The jig is not a cure-all, just a help. The most important thing for successful grinding is knowing what a correctly ground edge is shaped like and when you don't have it.

Well, you captured me on this one.
Actually, its an interesting question. First, I have no doubt that almost any good jigging system will offer more consistent repeatability of grind than hand honing. The issue here is how precise is necessary and desirable. With regards to the necessary part, well, anyone who has looked at some of the gouges Richard Raffan has ground will know that in the hands of a skilled turner (and perhaps a lot of lesser turners as well) one can have multiple irregular facets and do just fine. As for desirable, I remain convinced that jigging systems will allow the least steel to be removed to obtain an effective new edge. So if tool life is a big deal (and with the price of some of the exotic alloy gouges, it is), then choosing a system that will prolong tool life is desirable. But more to your point, are their reasons to assume that some turners will have less physical ability to free hand sharpen than others, and I think this is an unequivocal yes. However, the very things that would detract from one's ability to sharpen would dertract from one's ability to obtain good gouge cuts. Still making turnings can involve more than sensitive use of a gouge or skew (40 grit sandpaper can do wonders) while minus a jig, their are fewer alternatives with sharpening. So what might interfere with hand held sharpening. Well three come immediatly to mind: 1, reduced fine motor coordination; 2, reduced tactile/proprioceptive feedback; 3, poor visual acuity and reduced contrast sensitivity. All of these circumstances are not that uncommon in folks as they get older, particularly if they are diabetic and have developed a bit of peripheral neuropathy. Of course there is just natural variation in eye-hand coordination, regardless of age. I know you know these things, but I rose to your bait because I do think the point is significant. Anyone who follows sports, among other things, knows there are is a range of natural abilities, and that some will be able to accomplish things even the most motivated of others cannot. There is no reason to assume that the skills involved in unassisted precision sharpening are any less vulnerable to natural variation than any other activity requiring manual skills.

Or any less effective, especially as you can gain assistance by using the
tool as its own "jig" when sharpening or honing. Follow the existing grind by laying it on the wheel heel first, and raising to the edge. Slow speed and fine wheels seem capable of renewing the edge in a single pass, or at best a full R to L and L to R. Think of it as a powered hone. Of course, there's always the problem of bi or trifocal lines for us old fellows. "Lyn J. Mangiameli" wrote in message nk.net...

One thing is that when cutting with a gouge you use full body motions
without significantly rotating the tool. Sharpening involves more hand movement and rotation of the tool, making it more difficult. |

Y'think? I sharpen as I cut, personally, with a fixed point on the grinder
rest and movement of a gouge handle pretty much equating (lead half) to how I set a cut on the convex work surface, with a opposite follow-through equating to how I set a cut on a concave surface for the trailing half. Those sharpening with a bevel self-jig should not move that anchor hand, but keep it as the fulcrum for body or hand movements of greater degree on the long side of the lever which correspond to minor movement on the short side. In short, pretty much as if you were turning the stone. Did I mention that the center of my grinder is at the same height as the center on the lathe? "Derek Hartzell" wrote in message ...

Hi Folks,
If you have both a system and a jig which allows quick "brainless" sharpening, you are then more likely to improve your turning since you will sharpen as soon as you think you need it rather than waiting for a good time! I am able to sharpen a parting tool and 2 gouges in around 2 minutes time and resharpen a single gouge in less than 30 seconds with the Big Tree Tools sharpening system (belt sander) and the Packard bowl gouge jig. My turning has improved immensely since I purchased these items. George "Joe Fleming" wrote in message om... Arch, I agree that it is a skill to a point.

George,
No doubt, jigs help a turner get and repeat a good edge for their tools. My point, however, is that you can still "screw it up" even with a jig if you don't learn the fundamentals of grinding and tool geometry. Please allow me to turn up the contrast a bit. On most bowl gouge jigs, the tool is held in the correct position as it is swept across the grinder or belt sander. If, however, while the tool is still in the jig, you were to simply place the nose of your tool against the belt/wheel and leave it there for an extended length of time, you will seriously alter the geometry for the worse. While turners won't do that, over time the sweeping motion that you use could have you taking progressively more metal from the nose than from the wings. Over time, you may end up with a nose ground too much even with the jig. This is why a turner needs to understand the basic shape that is desired so that they can correct their use of the jig when needed.

I agree with Lyn as long as you assume that the turner knows how to
sharpen in the first place. You may not have the dexterity to sharpen (and all that other stuff Lyn said), but you must know what a correct edge is like for your tool. Jigs, fine motor skills, e\X-ray vision and everything else can't make up for a lack of knowledge adout what a correctly-ground gouge should look like.

Hi Joe,
I am making the assumption that the turner will select a basic shape that they think will work for them. I found that once I was able to continuously return to that shape, I really began to experience improvements in "predictive turning". To me that is the essence of "fast brainless jig sharpening". Works for me, but others may find different approaches more satisfying. George "Joe Fleming" wrote in message m... George, No doubt, jigs help a turner get and repeat a good edge for their tools.
