RUWI and Aigner
Let's join forces. To make the workshop better.
When you’re cutting shapes or contours on a circular saw, the process is often cumbersome: marking the line, aligning it on the sliding carriage, holding it in place, cutting, and making adjustments if necessary. The AIGNER Sägeboy takes this tedious process off your hands: attached to the rip fence without tools, it lets you use a template or tracing guide to cut shaped parts to exact measurements with repeatable precision in a single pass—and trim any protruding edges flush.
The anodized aluminum guide rail (Universal: 940 mm) provides a stable support for the workpiece along its entire length. You can adjust the height using the T-handle and knurled nut, and later find it again using the scale without having to measure it again. Depending on how the edge is positioned relative to the saw blade, you can cut flush with the template or leave a deliberate overhang for milling or sanding.
Here's how to use it
- Shaped parts from a template: Pre-cutting balcony boards and contoured parts—the template runs along the guide rail, and the part goes on to routing already sawn to shape.
- Trimming edge overhangs: Cut glued-on solid wood edges to size directly on the circular saw—without having to go through the router first.
- Cutting coatings flush: Cut veneer and HPL overhangs flush with the edge using a fine-tooth blade, or with a slight setback to allow for finishing.
- Chamfering without an auxiliary fence: Chamfer cuts made directly against the rip fence, without any additional setup.
Does this fit your saw?
When ordering, select the model based on your saw’s rip fence system: Universal for standard parallel rip fences (threaded hole with knurled screw; secured to thin-walled fences with a nut), Altendorf / Format 4 for Altendorf, Felder, and Format 4 rip fences (rear clamping), and Martin for Martin rip fences (also rear clamping). Instructions for use are included; additional safety and guidance accessories are available in the AIGNER collection.
