Description

The Accu-Wedge Segment Cutting Accessory

The “Accu-Wedge” is an accessory carriage for the precision cutting of the wedges for segmented wood turning on the band saw. By cutting these segmented wedges on the band saw, much less wood is wasted (as compared to a table saw) due to the narrow kerf of the band saw blade. In addition cutting these wedges on the band saw is much safer than cutting them on the table saw.

The Accu-Wedge is operated in conjunction with the Accu-Slice band saw accessory rail and carriage system with roller bearing slides. The Accu-Wedge Auto-Indexing Table is constructed from a 9.5” wide by 15” long 5/16” thick hard coat anodized aluminum plate with four roller bearings mounted on its base. These roller bearings slide effortlessly on the Accu-Slice rail to provide for smooth and accurate cuts on the band saw to produce precision segmented rings with no gaps or spaces between the wedges in the rings. The all metal construction of the Accu-Wedge provides for a quality system that is sturdy, versatile and highly accurate.

The Accu-Wedge has two independent pivoting aluminum fences with the ability to set an accurate angle between the two fences. A similar technique has been used with wedgies on a table saw in the past. However with the Accu-Wedge there is no need for the wedges or angles. The angle for the two fences is set with an auto indexing system that locks the fences in place with pins and locking indents which have been precision machined into the Accu-Wedge table with an accuracy of better than 0.1 degrees. There are a total of 17 possible segments per ring combinations from 4 to 72 segments per ring that have been auto indexed into the table including the odd segments 5, 7 and 9.

Auto-Index Table Positions - Cutting a wood segment on the Accu-Wedge

A channel slot has been machined into the top of each of the fences to enable the attachment of accessory clamps to securely hold your wood when cutting the segments on the band saw. This will provide for the optimum accuracy of the joints in your segmented rings.

The Diversion Ramp with Magnets and 2 Clamps are included with the Accu-Wedge System

The Accu-Wedge system as shown includes the Accu-Wedge Auto-Index Table, two fences with channel slots, two clamps and a dust shield attached to the bottom of the auto index table to protect the roller bearings from becoming clogged with saw dust. Included also is an Aluminum Diversion Ramp with magnets to hold it to the band saw table. This ramp enables the cut wedges of wood to slide away from the band saw blade after cutting so that the cut wedges do not get caught up in the band saw blade teeth.

In addition a number of optional accessories are also available for use with the Accu-Wedge including:

  • A Stop Jig which enables the accurate and reproducible setting of your segment lengths. The Stop Jig is held in place on the band saw table with a strong MagJig Clamp. This jig incorporates a fine adjusting screw and a locking nut to enable the fine tuning of your wood segment ring dimensions.
  • The Accu-Path can be attached to your band saw with magnets or permanently attached with screws to your band saw. This laser marker enables you to accurately determine the exact position and path of your band saw blade cuts.
  • A variety of additional accessory clamps of various sizes for the holding various thickness of wood strips on the Accu-Wedge table.

Band Saw Blades

Band Saw Blades

For the optimum performance of the Accu-Wedge on the band saw we recommend using ¾” wide by 14 teeth-per inch (tpi) band saw blades. These wider and thicker blades will enable the accurate cutting of the wedges with perfect fitting joints with no gaps. The fine 14 tpi blades provide for the smooth cuts on the cross grain edges of the wood segments.

When using the standard ½” wide blades, we have noticed some minor blade drift as you cut across the wood pieces at an oblique angle. These ½” blades work fine on the Accu-Slice system with no blade drift when cutting parallel or at 90 degrees to the wood grain. However when cutting at an angle between 20 and 70 degrees across the wood grain, the wood grain tends to pull the blade ever so slightly to one side. Increasing the band saw blade tension can help minimize this problem but the increased blade tension may cause the blades to break prematurely at the weld joints.

Therefore we recommend using the ¾” wide band saw blades with the Accu-Wedge to eliminate this blade drift problem and enable the production of perfect segmented rings on the band saw. The ¾” wide x 14 tpi blades are available from the Timber Wolf Band Saw Blade Company.

Two styles of blades are available - both wood and metal cutting blades. We have used both with the Accu-Wedge. We have obtained excellent results when using the metal cutting blades. Even though this blade is listed as a metal cutting blade, they cut accurately for cross cutting applications on wood and cutting the segment wedges with the Accu-Wedge and Accu-Slice Systems.
