Turn Your Router Boss into a Router Lathe
Now you can turn tapered table legs then add decorative details with this powerful new accessory for your Router Boss. Just chuck square stock and start milling as the blank spins between the supplied head and tailstock. With just a few step cuts, the square will be turned round. Tapering is automatically achieved when the bed rails that mount to the Router Boss are positioned at a slight angle.

But That's Only Part of the Story
The versatile Router Boss was designed to provide control of the cutter along the 3 axes of X (length), Y (width) and Z (depth) making many types of joinery possible. The new 4th Axis Work Holder adds a rotary axis where the cutter is positioned by turning the work piece. This is also called the A-axis. By controlling the cutter path simultaneously in the X, Y, Z and A axes, a whole additional range of production work becomes possible.

2 Modes
Our 4th Axis Work Holder can be used either in an “indexing” mode or in a “continuous” mode. In indexing mode, the stock is milled while locked at some fixed degree increment. By contrast, in continuous” mode cutting happens as the part is being rotated.

Indexing
Inlay
You may wonder why you’d ever want anything but continuous machining, but plenty of work (perhaps even the majority of 4th axis work) is done simply with indexing. With the indexing head set and locked into position, routing operations can be made along the X (or length) axis. In the video below we cut lengthwise flutes in a spindle leg. The tool indexes each cut position in increments as small as 5° around the 360° rotation. For 9 flutes the stock is rotated every 40° then the cutter makes the flute cuts.

It’s very powerful. Gerry Kmack of Cave Creek Woodworks uses the 4th Axis Work Holder index capabilities to create blanks of multi-colored wood which he then turns on his lathe into colorful ornaments. Click here to view Gerry's work.

Contouring
Magnate Bits
However, 4th Axis continuous machining is the more fancy stuff, which is also referred to as “4th Axis Contouring”. With continuous machining, you can machine shapes on Router Boss that would otherwise be impossible or very difficult such as work normally requiring a lathe. In our video we shape a round tapered spindle leg from a square blank. You can also add variety to your work with plunge-style router bits up to 2-1/4" diameter from Magnate that were designed for the Legacy Ornamental Mill. Very accurate positioning is possible with the Router Boss digital readouts.

Adding the optional 4th Axis Work Holder to your Router Boss provides another axis to work with and makes your Router Boss more diverse in the work it is capable of doing.

What's Included?
Click here to view instructions and parts list. The index head, tailstock and bed are made by Sherline in California to our specifications.

Headstock Adapter
Included are both a polycarbonate headstock adapter for up to 2-1/8" square stock plus a faceplate, both which can be mounted to the index head. You can also purchase standard chucks from Sherline for the index head.
