A replaceable carbide point contacts the tooth in
the middle of the swaged pocket for an especially uniform grind. The sharpener stops
grinding automatically after one pass of each tooth.
Armstrongs SideWinder feed finger is
designed to increase the accuracy of Armstrong band saw sharpeners.
Both styles of SideWinders pivot around the side
of the tooth just below the Cobalt Chromium Alloy tip or swaged point. The carbide feed finger never
touches the Cobalt Chromium or swaged tooth cutters unlike the original over-the-top feed finger
or cheap imitations.
To ensure accurate grinding, the SideWinder is
easily adjusted to position the feed finger square to the tooth. The swaged tooth version
of the SideWinder also independently adjusts the carbide point to feed in the center of
the swaged pocket.
The improved SideWinder uses
"air-craft" type bearings to support the feed finger. There is no end play and
grinding grit will not interfere with the action of the SideWinder.
