Tool Review: Arbortech Ball Gouge
By Jeff Fleisher

The Arbortech Ball Gouge is a carving tool that is designed to create small concave surfaces in wood. The head of the gouge has a 30mm diameter ring-shaped cutter that is just the right size for shaping small carvings, bowls, spoons and chair seats.

The ball gouge attaches to a 4 or 4-1/2” angle grinder which is perfect for free-hand shaping of wood or carving. I started out in the early 1990's as a wood carver and I found the ball gouge very easy to use after about 30 minutes of experimentation. Once you get the feel of using the ball gouge over various grain directions it becomes very comfortable to use.

The package comes with the ball gouge, an Ian Key and an instruction booklet. The Ian Key is used to loosen a screw at the tip of the cutter head in order to rotate the cutter blade so that you can use all portions of the blade.

The ball gouge has a ring shaped blade that you can rotate as one part gets dull and is eventually replaceable. It will mount on the 5/8” shaft of an angle grinder and can handle speeds up to 12,000 RPM. The blade is mounted at a 30 degree angle onto the inner head. The gouge is used at an angle such that the inner head prevents it from digging into the wood. Arbortech calls this their "Anti- Grab" Technology. Instead of digging in and grabbing the wood, it will bounce out of the cut.

The cutting action creates a chisel-like texture as if you were making the cuts by hand with a conventional gouge and mallet. It also makes small chips rather than sawdust. I recommend you still wear a dust mask when using the ball gouge but you won't be surrounded by a cloud of dust.

After about 30 minutes of practicing with the ball head and having it bounce around and tear up some cross grain wood I finally got the hang of using it and made some very nice looking depressions in a cherry board. In all seriousness, it takes about 30 minutes to get a feel for which part of the tool to use as you move with the grain and across the grain. Once you have the feel for the tool, you can draw boundary lines on a piece of wood and carve right up to the line under control. As I've mentioned earlier, the surface has a natural chisel-like texture, is very smooth and the blade cuts very quickly.

Once my cuts were looking good I decided it was time to put the ball gouge through its paces! As a woodturner I've turned a lot of bowls but on a recent cross-country trip I saw some very nice hand-cut oval shaped bowls. I thought it would be a very interesting shape to create using the ball gouge. I started out with a block of cedar and drew a rough outline for an oval bowl with an elongated rim on either end.

It took only a matter of minutes to nibble away the waste wood at each end and to start to give the bowl a rough shape. I started on the outside so I could create an overall look and could then hollow out the center guided by this shape.

Once I had the ends shaped I could literally start to 'draw' with the ball gouge and blend the ends and sides together. The gouge easily moved back and forth along the long grain direction and blended nicely into the end grain. If you were doing this by hand you would be continuously remounting the blank in the vise to be able to chop with or across the grain. Using the ball gouge, I could leave the blank mounted in the vise and easily move the grinder and gouge around to continuously refine the shape.

Once the outside was roughed in I turned my attention to the inside. By changing the angle of the ball gouge you can take either an aggressive cut or a lighter, smoother cut.

The ball gouge can go deep in the center and then blend that cut into the side walls to slowly work down to the proper depth and width. I could control the aggressiveness of the cut which allowed me to design and cut at the same time. After a few minutes I had my 'final' bowl. It could actually use some final touches but getting to this point was fun and easy!

I was very impressed with the Arbortech Ball Gouge. The surface it created looked like a hand-cut surface from a chisel and mallet and it had a very reasonable learning curve. You can easily sculpt a shape with a high degree of control. If you need a tool for small scale shaping and carving, the Arbortech Ball Gouge is for you and you won't be disappointed.
