With wolverine jig system yupoo Vari-Grind Attachment you will properly shape and maintain the edge on standard bowl gouges, the modern side grind and the traditional fingernail shape for spindle work detailing. Loose magnets will jump up and attach to a CBN wheel. The platform jig works great for scrapers, etc. Position the bowl gouge so that material is first contacting the grinding wheel. I was skeptical when I purchased this sharpening system, but I needed my lathe tools sharpened. I have more of a question wolverine jig system yupoo a comment. I agree about the need for a video and I will be producing such a video.

On purchasing this item I have been able to sharpen my chisels and they have stayed sharper longer because I have been able to sharpen my tools properly. I believe this is a wonderful piece of kit. Comments On Apr 24, This skew jig does a good job but there is a catch.

Due to the style of the jig, this will slightly change the angle you're grinding at. To learn more about the process I use to sharpen Massca Pocket Hole Jig Vs Kreg System my bowl gouges, read this article next. Remember, once the bevel angle is established, the whole process of sharpening the bowl gouge should only take a few seconds, and a couple passes back and forth. The ultimate goal, once a bevel angle is acquired, is to reestablish a sharp cutting edge, not grind metal away.

The Wolverine Vari-Grind Jig is an investment that will quickly pay off in saved bowl gouge metal and reduced frustration by maintaining consistent sharpening experiences.

If you do, what would you add to this conversation? Please leave me a comment below. PS — How would you like to help me out and make this site even more useful?

Leave a comment below and let me know what you would like to know more about when it comes to wood bowl turning. I have not, but I guess you could use that range possibly for detail spindle gouges, as long as the bevel is up near the top of the wheel. There would be little or Wolverine Jig System no support against a catch and the tool could easily be slammed downward. I have more of a question than a comment.

I do enjoy your teaching ability, you have taught me a lot. In this article you are changing the angle of the nose or cutting surface of your gouge by adjusting the setting of the extension leg. For a 55Deg nose you set the leg at 3 , then for a 45 Deg nose you set the leg at 2 which makes sense to me the leg is closer to the shank of the tool decreasing the angle.

But then to get a 65 deg nose you move the leg to 1 position which is closer to the shank than 3 55 Deg or 2 45 Deg position but making an increased angle on the nose? I must be missing something. Please explain this to a novice. Thank you a gain for teaching the world how to turn a bowl and keep your tools sharp. Great question. The nose bevel angle is controlled by the in and out position of the V-arm.

The Vari-grind jig leg angle controls the amount of wings on the bowl gouge. I usually use a 3 or 4 position for my swept-back bowl gouge which makes the wings long and swept back. The micro-bevel, on the other hand, is sharpened on the 1 leg position and has a bevel that wraps around the edge of the flute and does not have swept-back wings.

Hopefully that helps a bit. Do your setting recommendations for the Vari-grind also apply to the Vari-grind 2? Also, does your sharpening e-course include the Vari-grind 2? Yes, the settings are the same. But do not switch jigs on a gouge, as the profile might change a touch. Hi Wolverine Jig System Problem Ken great review, i have an unrelated question about your lathe.

You have the sweet 16 and i am looking to get either the American beauty or the sweet My concern is the ability to use a bowl stead rest for large bowl. Are you able to use a bowl steady rest on the sweet 16 with rail removed for large bowl? I do not use a steady rest nor would I for bowl turning. Perhaps a steady rest would be appropriate for a longer hollow form turning, but not bowls. If this is something you want to use, I think the American Beauty might be your answer because of the taller swing.

Many thanks, Kent. I have recently set up the Vari-Grind and have been experimenting on how best to shape some old gouges I received in conjunction with a second hand lathe I bought. This is because, I strongly believe, your instructions will provide me with a much shorter learning route to better shape and sharpen my gouges. Great article. One of the firsts I can find that properly adresses the angles of the vari grind jig. I have to questions. What is the difference, when it comes to sharpening, between the iris and ellsworth grinds.

Vari grind angles? And how do you sharpen a spindle gouge and what angles works for what applications for the spindle gouge. I rarely see an article on spindle gouge sharpening. The Irish and Ellsworth grinds are very similar. The Ellsworth grind is a bit longer-winged and the wings have a slight convex curve to them. Sharpening a spindle gouge is an elusive topic.

You are right! Perhaps, I need to do an article on that subject. I think it is elusive because there are a few ways to go about sharpening a spindle gouge. I use a detail or longer, more pointed spindle gouge to undercut my dovetail angles on my tenons. There are turners that use the Oneway sharpening system to grind the main bevel on a spindle gouge.

It seems there are many different custom shapes possible when sharpening a spindle gouge. But the main principle that the bevel needs to be clean and smooth right up to the top cutting edge applies to every different style.

Hello Kent, I have been turning for over 50 years. I have systematically upgraded my systems and processes using the best technology and techniques available. I, of course, had to wade through a quagmire of information…mostly opinions…and a lot of technology that I had to assimilate. I have only recently discovered your…I suppose it is called a blog these days…and find it totally validating. Your explanations simplify a lot of technical information so that the average person can understand.

Bravo to you…!! In other articles you caution against that practice Wolverine Jig System 70 with HSS…which I agree with. Thanks for making woodturning understandable in such a congenial manner. Thank you for taking the time to share your kind words. I especially appreciate your insight based on your turning experience and background. That is why I put the time into this site to make everything as clear as possible for as many as possible.

I want to write an article about the subject, but finding definitive information is difficult. Even tool manufacturers, that I have contacted have varying ideas.

However, if the tool discolors, the colored area should be ground off. It would be nice to know for sure which bevel angle is optimum for what part of the bowl. For instance a 40 degree angle might be optimum for the push cut from the bowl edge down the inside of the bowl since it would position the tool handle roughly parallel to the lathe bed assuming a 5 to 10 degree bowl side taper.

Would a 40 degree bevel facilitate use of the tailstock without interference with the the tool handle when push cutting the bowl side compared to a greater degree tool bevel?

The 55 degree might be optimum for the curve between the inner side and the inside bottom of the bowl and the 65 degree bevel might be best for the inside bottom of the bowl. Does it matter what bevel is used on your shearing bowl gouge? I understand how a longer slightly convex sweep might be optimum for shearing cuts outside the bowl. Would that be a negative rake scrapper tilted for a shear cut? Can the bowl gouge be used for shearing inside the bowl by using a high angle closed tool pull of some sort?

When rough turning green wood is it typical to leave a spigot big enough to be captured by your chuck after shrinkage in the center inside bowl? A round jam chuck would touch on only two sides of the dried bowl due to shrinkage. First off, the bevel angle is a personal preference, but some physics do start taking over at times. Read this article — Bowl Gouge Sharpening Angle for starters.

I will use a Micro Bevel bowl gouge for deep bowls or inset inward tilted rims. You really want a sweptback winged bowl gouge to execute shear scraping passes. Read this article about Shear Scraping. There is an infographic which illustrates which gouges work best for shear scraping. Occasionally I need to fine-tune an inside curve with a Round Nose Scraper, see this article.

Green wood twice-turning does require you to make the tenon oversized initially. When the first rough turned piece dries, then you can turn a true tenon to the correct size and continue finishing the bowl.

I use a plywood plate with padding to brace the twice turned bowl during the second turning. I have a detailed article on twice turning coming out soon. Stay tuned. Question, when reshaping a bowl gouge does the top angle from above the top sides of the flute to the tip get ground separately to form the slope or does this happen naturally as a function of sharpening the wings?

My concern is that I have not seen a guide include this as a step, so I wonder if sharpening the wings simply results in this happening naturally. Yes, you are spot on. The best way to grind the top back first is to match the angle you desire of another gouge you have on hand. Making that top grind first reduces the amount of grinding needed for the sides. If you decide not to grind the top, the sides will naturally form but they will take a bit longer. Clear and concise. Thank you, Randy!

I agree about the need for a video and I will be producing such a video. As they say, stay tuned. Username or Email Address. Remember Me. So how do you adjust the Wolverine Vari-Grind Jig? Have you experimented with the vary grind leg angle 5,6, or 7 with regards to the wings. Hello, Kent! Thank you! Gary, Thank you very much!

Happy Turning, Kent. Hello Kim, Thank you for the comment. And yes, I will have videos coming soon to enhance content throughout my site.
