The Oneway Wolverine is a modular jig system that mounts on any standard bench grinder and holds turning tools at precise, repeatable angles. The base system costs $104 and covers most tools. Adding the Vari-Grind 2 attachment ($127) enables consistent fingernail and swept-back profiles on bowl and spindle gouges. It’s sold at Woodcraft and Craft Supplies USA, and is manufactured by Oneway Manufacturing in Canada.

The Wolverine does not replace a bench grinder. It is a jig that rides on the grinder you already own or buy separately. That distinction matters for the total-cost calculation: a “complete Wolverine setup” means the jig plus a compatible grinder, not just the $104 base kit on its own.

The base kit is the starting point. The Vari-Grind 2 is the upgrade most bowl turners add immediately. The Skew Jig is for dedicated skew chisel work.

Bundle note: The Woodturning Store has periodically sold a Wolverine plus Vari-Grind 2 bundle for approximately $180. When in stock, that pricing beats buying the components separately.

What the base kit does

The 4-piece base kit gives you two mounting hardware pieces (one per wheel on your grinder), a V-arm support, and a platform.

The V-arm holds a tool at a fixed height above the platform. You set the tool in a pocket on the arm, adjust the arm’s height for the bevel angle you want, and grind. The geometry repeats consistently because the height is set rather than eyeballed. This handles roughing gouges, parting tools, spindle gouges (basic grinds), and most flat-bevel tools.

The platform handles scrapers, flat chisels, and any tool that benefits from a flat register against the wheel face. It’s 3 by 5 inches of quarter-inch steel plate.

Both attach to the bases with a cam-lock mechanism Oneway describes as a 10-second process. You can move the bases to a second grinder or store them flat with minimal effort.

The Vari-Grind 2: why bowl turners buy it

The base V-arm produces flat-bevel grinds efficiently. What it cannot do is hold a gouge at a consistent rotation angle while you bring it across the wheel, which is the motion required for a fingernail grind or swept-back profile on a bowl gouge or spindle gouge.

The Vari-Grind 2 is the attachment that solves this. It cradles the gouge body in a V-block mounted on the arm, sets the flute rotation angle with a set screw, and allows you to swing the gouge through the grind arc while the arm holds the presentation angle. The result is a reproducible fingernail or swept-back profile every time.

Without the Vari-Grind 2, you’re either grinding the bowl gouge profile freehand (which is a skill that takes significant practice to make consistent) or accepting a simpler flat-bevel grind that limits the gouge’s range of cut. For turners doing serious bowl work, the Vari-Grind 2 is not optional; it’s the component the jig was designed around.

Setup note: The Vari-Grind 2 arm projection (how far the gouge nose protrudes beyond the arm) determines the bevel angle. Oneway’s documentation and the Turn a Wood Bowl setup guides cover the typical projection settings for 45-degree, 55-degree, and 65-degree grinds. The initial calibration takes one session; after that, setup is repeatable.

Grinder requirements

The Wolverine works on any 6-, 7-, or 8-inch bench or pedestal grinder. Most turners use an 8-inch machine because larger wheels give more surface area for consistent grinding and dissipate heat better.

Compatibility relies on the grinder’s arbor height being approximately 6 to 6.5 inches above the mounting surface, so the bases fit below the wheel shroud. Virtually all standard bench grinders in the 6- to 8-inch class meet this dimension.

Speed recommendation: Slow-speed grinders (1,750 RPM) are preferred over standard-speed grinders (3,450 RPM). At lower wheel speed, there is more time per pass to feel the angle, and less heat accumulates in the tool steel. The difference matters most when reshaping a gouge significantly, the kind of work where several passes are needed. Standard-speed grinders work with careful technique; slow-speed grinders are more forgiving.

The wheel upgrade: The stock aluminum oxide wheels that come with most bench grinders work adequately with the Wolverine. CBN (cubic boron nitride) wheels are a meaningful upgrade: they cut faster, generate less heat, and do not require dressing. The AAW community consistently recommends switching to CBN wheels as soon as budget allows.

Total setup cost

The base kit and a compatible grinder are the required components. Everything else is optional in sequence:

StageComponentsApproximate cost
BeginnerWolverine base kit + Rikon 80-805 (1/2 HP)$239
Bowl turnerAdd Vari-Grind 2$127 more / $366 total
Serious setupRikon 80-808 (1 HP) instead of 80-805+$155 / $521 total
Upgraded wheelsCBN wheel pair (60/80 grit)+$80-120 / ~$600 total

For comparison, a Tormek T-4 wet grinder (grinder, jig, wheel) runs approximately $620 to $700 as a complete unit. The Wolverine at the “serious setup” tier lands in the same range and is faster for reshaping profiles, at the cost of slightly more operator attention to avoid overheating.

Wolverine versus Tormek

The Tormek produces a finer edge from its slow, water-cooled stone wheel. The edge from the Tormek lasts slightly longer between sharpenings. It is also cleaner to use because the wet process keeps grinding dust down.

The Wolverine is faster. Reshaping a bowl gouge from a worn profile back to a proper fingernail takes 5 to 10 minutes on a dry grinder. The same operation on a Tormek takes 15 to 20 minutes or more because the fine stone removes material slowly. For a production turner who reshapes gouges multiple times per session, the Wolverine’s speed is the practical advantage.

Many serious turners run both: a Wolverine setup for reshaping and heavy work, a Tormek or fine leather strop for final edge refinement before a finishing cut. The sharpening setup guide covers how these two approaches fit together in a complete station.

Owner feedback

The AAW and LumberJocks communities are the primary owner feedback source for the Wolverine, and the consensus is consistent: it works as documented, the setup investment pays off quickly, and once dialed in, most turners do not consider replacing it.

The most common complaint is the learning curve on the initial Vari-Grind 2 calibration. Getting the arm projection set correctly for your preferred bowl gouge geometry takes experimentation. Once set, it stays set and reproduces reliably.

One repeated observation: having a dedicated setup for each gouge you use regularly (your bowl gouge at your preferred projection, your spindle gouge at its projection) eliminates most of the per-session setup time. Many turners mark the arm positions with a Sharpie.

Who the Wolverine is for

Every woodturner who does more than occasional turning will eventually need a jig system. The Wolverine is the system that most AAW chapter members use, which has a practical advantage beyond its own merits: other turners can help you set it up correctly, videos covering its setup are widely available, and the institutional knowledge around it is extensive.

For tool setup context: the first turning tools guide covers what goes on the tool rest, and the Rikon low-speed grinder review covers the grinder half of the sharpening station. The Jet JWL-1221VS review and Nova G3 chuck review complete the picture of a fully equipped turning setup at the midi-lathe tier.

Frequently asked questions

What is included in the Oneway Wolverine base kit?

The Wolverine base kit (4-piece set, $104) includes two grinding bases that mount below each wheel on your grinder, a V-arm support arm (27.5 inches long), and a platform assembly (3 by 5 inches of quarter-inch steel). The V-arm and platform cover most tools. The kit does NOT include a bench grinder, the Vari-Grind 2 attachment, or the Skew Jig; those are sold separately. You must own or purchase a compatible 6- to 8-inch bench grinder before the Wolverine can be used.

Do I need the Vari-Grind 2 attachment for the Wolverine?

If you turn bowls, yes. The V-arm in the base kit handles roughing gouges, parting tools, and basic spindle work, but it cannot reliably produce the consistent fingernail or swept-back grinds that bowl and spindle gouges need for curved-cut work. The Vari-Grind 2 ($127 at Woodcraft) holds the gouge body at a fixed angle while you rotate it, producing the same flute geometry every time. Without it, you're freehand-grinding the profile, which works but takes more practice and produces less consistent results.

Will the Oneway Wolverine work with my existing bench grinder?

It works on any 6-, 7-, or 8-inch bench or pedestal grinder. The only requirement is that the grinder's arbor shaft sits approximately 6 to 6.5 inches above the mounting surface, so the Wolverine bases can fit below the wheel shrouds. Standard bench grinders in this size range almost universally meet that dimension. It will NOT work on angle grinders. The Wolverine bases attach with a cam-lock mechanism that Oneway describes as requiring about 10 seconds to mount or remove.

How does the Oneway Wolverine compare to the Tormek system?

The Wolverine is a dry-grinding jig; the Tormek is a wet-grinding system with a slow, water-cooled stone wheel. The Wolverine is faster for reshaping tool profiles (5 to 10 minutes on a dry grinder versus 15 to 20 minutes on the Tormek's fine stone). The Tormek produces a slightly finer, longer-lasting edge due to its fine-grit stone and water cooling. Total cost is roughly $430 to $530 for a Wolverine plus grinder versus $600 or more for a Tormek T-4. Many experienced turners use both: Wolverine for reshaping, Tormek or a leather strop for final edge refinement.

What is the total cost of a complete Wolverine sharpening setup?

Base Wolverine kit ($104), Vari-Grind 2 ($127), and a Rikon 80-808 bench grinder ($290) comes to approximately $521. Replacing the stock aluminum oxide wheels with CBN wheels adds $60 to $120 depending on the supplier. A complete Wolverine sharpening station for a serious turner runs $500 to $650. For a casual beginner, the Wolverine base kit on a Rikon 80-805 (half horsepower, $135) is $239 and covers basic sharpening needs before adding the Vari-Grind 2.
