Hello Reuben, Thanks for wolverine jig system problem comment and great questions. It is a must have for any turner. You have the sweet 16 and i am looking to get either the Wolverkne beauty or the sweet Robin Thompson. Perhaps a steady rest would be appropriate for a longer hollow form turning, but not bowls. I tried to round the wheels on my grinder with very little success. This is a great and necessary addition to any shop with a wood lathe.

I have always had a hard time getting a good edge on chisels, this makes it quick and easy. It is easy to set up and use. I don't have anything bad to say about it. Easily adjusts to any tool angle, keeping the grind exactly as it was, or can be easily adjusted to a new angle as your preferences change.

Great jig, couldn't sharpen without it. Takes a little time to set up, but it works as advertised. Perfect bowl grinds every time. Easy way to get a quick and repeatable sharp edge. This is a must have shop item if you use turning tools. Makes the sharping of your tools quick and easy, so you can spend more time on the lathe. Best jig available for sharpening chisels - especially woodturning chisels.

Simple to use and set up. A bit costly - you can make one yourself for little or no cost. However, this one will last and last, with no slippage or guesswork. Good quality construction. The tool is apparently designed for an 8" grinder as it has a tendency to catch and kick back when using it on a 6" wheel.

This is due to having to bring the cutting edge down low on the wheel to get the correct bevel. The platform jig works great for scrapers, etc. I use it to sharpen all my woodturning tools.

As for the vari grind, do not even think about grinding bowl and spindle gouges to fingernail, Elsworth or Celtic or whatever you want to call it with out this jig. These jigs are a must have unless you are that rare person with perfect hand and eye control every time. Very easy to setup and use. Makes sharpening turning tools very simple and easy. You get the same grind on the tool each time. A well designed product that does just what it claims to do.

Greatly simplifies the sharpening of turning tools. I use this jig for sharpening all of my woodturning tools. The platform is great for Scapers and my Spindle Roughing Gouge. The size of the platform is adequate but in a few instances I could wish for a larger one. It is very easy to adjust. The V arm will slide into either side as will the platform so if you have a preference you have an option. That isn't a problem though. The most important thing is to make sure the wheels are lined up directly over the center of the slide.

This keeps you grinding in the center of the wheel. A system designed to outlast three or four generations of woodworkers, BUT It is sorely lacking in installation instructions. There must be a practical way to set up the alignment with the grinding wheels.

Maybe a template of the Wolverine's footprint, adjustable to major grinder manufacturers. I'm just saying The jig has good instructions on how to setup and how to safely use. Once setup, it takes about 10 seconds to sharpen a tool and get back to work on your project. Highly recommend this product. The product set up easily and produced a consistently sharp turning tool. The video, which you can watch on YouTube, gives some clever hints on how to sharpen. Highly recommended. This is a great and necessary addition to any shop with a wood lathe.

The included attachment does a very professional job on gouges and parting tools while the also included "platform jig" allows you to grind bowel scrapers and skew chisels. It does seem a bit pricey but it is a very good quality tool. This product is well made and was easy to setup. As a beginner to turning this jig makes sharpening my turning tools quick and easy. Experienced turners make most things look much easier than they really are but this jig really is as easy to use as it looks.

It is a must have for any turner. Allows repeatable, quick, very sharp wood turning tools sharpening. Wolverine jig. This unit functions as advertised. All chisels were easily sharpened at the right angle. If any portion of the system is not set up correctly, there will be deviations.

The final resulting bowl gouge sharpening grinds can vary dramatically if the system is misconfigured. As I mentioned above, there are three variables we need to deal with when sharpening at the grinder using the Oneway Vari-Grind System: Tip extension, Angle, and Distance. The distance the bowl gouge extends from the face of the Wolverine Vari-Grind Jig is consistently two inches. Set it and forget it. We do need to be aware that if we are extensively grinding the bowl gouge tip, usually when first establishing an angle, we may need to reset the extension length to two inches because tool material removal may shorten the tip.

Under the Wolverine Vari-Grind Jig is a protruding leg. The angle of this leg is a critical variable in the bowl gouge bevel angle sharpening process. We will be using the adjustable wing nut on the leg extension to move between various marks. The marks are indicated when the top edge of the leg aligns with the flat edge of a particular mark.

When adjusting the Wolverine Vari-Grind Jig leg angle, the lower the numbered mark, the less sweep will be applied to the bowl gouge side wings. A gouge sharpened at the number one mark will produce a narrow, tight bevel edge along the cutting tip.

While a gouge sharpened at the number four mark will have long pulled back bevel wings. Again, I have found conflicting opinions about what the V-arm distance from the grinding wheel achieves.

It has been my experience that the V-arm distance from the grinding wheel controls the front bevel angle of the bowl gouge sharpening. By moving the V-arm closer or farther away, we can set the front desired angle on the bevel of the bowl gouge. When sharpening a bowl gouge with an already established bevel angle, start by placing the bowl gouge in the Wolverine Vari-Grind Jig and snug the hand screw.

Place the extending bowl gouge tip in the measuring jig to the predetermined two-inch depth and tighten the hand screw. Adjusting the leg extension angle on the Wolverine Vari-Grind Jig may take a little guessing at first.

If the gouge has swept back wings, try setting the angle somewhere around the third mark and tighten the leg extension thumb screw. For shorter wings, try a lower numbered mark.

With the grinder still off, place the end of the leg extension in the pocket at the end of the V-arm. Slide the V-arm until the surface of the bowl gouge sharpening bevel is flush with the grinding wheel.

Take your time and look closely from the side and make sure the bevel is flush to the wheel. Using a backlight here is very helpful to find any gaps. This magnetic mounted LED task light mounts perfectly to the center of the grinder housing. Turn on the grinder and gently rotate the bowl gouge in the center of the sharpening wheel. If even contact is made around the front and side wings of the gouge, the job of adjusting the Wolverine Vari-Grind Jig is complete.

If an area or areas of the bowl gouge sharpening are not being ground and sharpened, tweaks need to be made to the V-arm distance or the leg extension angle. Take your time and make a note of the best final result. Depending on how the original angle was created, an exact match may be impossible. This will only waste metal and reduce the life of the bowl gouge. Only a clean bevel at the cutting edge is needed.

A protractor is a critical measuring tool needed for this process and for checking the bevel angle of all bowl gouges. Here is a link to the protractor I use. Place the base of the half circle of the protractor in the flute of the bowl gouge and rotate the arm to determine the current bevel angle.

Then dial in the desired bevel angle and tighten the thumb screw. Look at the gap in the bowl gouge sharpening bevel angle. Bowl gouge material will need to be removed to make this new angle. Dial in the amount of side bevel wing desired with the first mark being the least and third or fourth marks being far swept side wings.

Position the leg extension of the Wolverine Vari-Grind Jig in the pocket of the V-arm and slide the gouge bevel up to the grinder wheel, with the grinder off. Visualize the material that needs to be removed to get to the desired final bevel angle.

Position the bowl gouge so that material is first contacting the grinding wheel. Grind until the desired angle is achieved.

Note that you may need to stop occasionally and readjust the extension distance of the V-arm as more material is removed. Please read my article about which bowl gouge angle is best , and you will get the whole picture.

It is incredibly important to understand why and how each bowl gouge bevel angle will affect your wood bowl turning. With all that being said, I will share with you how I sharpen my bowl gouges and why.

Again, this is how I do it, you have no obligation to sharpen your bowl gouges the same way. Do what works best for you. Look at this as a guide and a way to understand how the Wolverine Vari-Grind Jig works.

I prefer swept back angles that serve various purposes from removing lots of material quickly to creating scraping and shear-scraping finishing cuts. This particular configuration is a great all-purpose bowl gouge bevel angle. Actually, a large and medium version of bowl gouges with this grind is all that is needed to turn an entire bowl. The finishing bowl gouge is what you might think, the final tool to make the last cuts of the bowl. I reserve this tool for only the last couple passes which keeps its cutting edge and bevel fresh and ready.

The superpower of the micro-bevel bowl gouge is the ability to work in tight spaces. For the micro bevel bowl gouge, the leg extension is set to the first position, and the V-arm again slides forward until the face bevel is flush with the grinding wheel. I remove multiple passes of the heel to help this tool access tight steeper angled areas. With each bowl gouge angle described above, I will usually remove some of the heel to make the tool more flexible and easier to turn tighter curves.

If the heel is left intact it can, at times, get in the way and make undesirable burnish marks Massca Jig Hole System Journal on the wood that would otherwise turn perfectly smooth. To remove or reduce the heel area, merely slide the Kreg Jig Pocket Hole System Canada Pro V-arm forward until just the heel is in contact with the grinding wheel.

Rock the Wolverine Vari-Grind Jig left and right until a smooth curve replaces the harder angle of the heel. I never use the handle of the tool while sharpening. All control and attention needs to be focused at the bowl gouge tip. If the gouge tip or jig slip off the edge of the wheel, the gouge can be pulled down violently and potentially cause damage.

Use fluid motions to grind away material evenly as you rotate the tool from left wing across the nose and over to the other wing. Continue making light sharpening passes until the top cutting edge of the bevel is clean and smooth all the way around the bowl gouge tip. If many passes are needed to get the tool shape desired, stop frequently and quench the tooltip in a container of water, so it does not overheat. The Wolverine Vari-Grind Jig will not do all the work for us.

We still need to apply a smooth even grind to the bowl gouge while using the jig. If too much time is spent on the wings, an enlarged nose might appear. If too much time is spent on the nose, high walled wings may result. Occasionally a fluid motion will be interrupted, and the gouge tip might stay in one area a bit too long causing a flat spot.

Sharp tools are a must! I use the Wolverine with a slow speed grinder rpm and Oneway wheels for changing the angle on new gouges and anytime I need to remove a lot of metal quickly. It is also very useful for skews, parting tools and scrapers. I really like having both systems and use the heavy duty Wolverine base for many other grinding tasks. Good luck. Chris Wright. Both are decent I own both the Tru-Grind and the Wolverine.

Both have their benefits. Main complaint on the Tru-Grind is getting to the wing nut to tighten the slide base, but the new version solves this. The tru-grind does allow for more grinds with a single jig, but what that translates into is fewer parts good with more adjustments not good. If you really need a jig, go with the wolverine.

Or do what I did and learn to freehand grind and get the basic wolverine with 2 platform bases Gerry Meekins. I have the Wolverene and am happy with it. I see the Kelton has a platform that has adjustable height. Might be a bit better for scrapers. That is if you know anyone that uses scrapers. LOL Anybody out there have the Kelton? OK, I decided to order the wolverine system. I found a package deal at The Woodturners Catalog web site.

But they have two different packages two differnt packages. One has this wheel dresser and the other has this jig. They both come with the wolverine and vari-grind. The only difference is the type of wheel dresser. Mark Mandell. Dudley said:. Click to expand Steve Worcester Admin Emeritus. Mark Mandell said:. It will work in the Wolverine, but only after a few moditifations to the base mounting.

Steve Worcester said:. You can easily replicate the Ellsworth grind with the Wolverine system, it will just take some patience. In the how too section on my website are a few articles on doing so.

One covers that exact subject and another covers how to use the Tormec with the Wolverine. In addition, to make it even easier, Don Geiger has a gismo that fits in the Oneway system that allows you to adjust the vertical height of the jig by adding an adjustment on the rod to allow for up and down. He also has a diamond point dresser that works extremely well. The problem with all dressers is that they will face the wheel, but not take out the out of round because the dresser just follows the wheel.

The diamond points by Geiger and Oneway will solve that problem.
