Lead Screw (LS) Technology

The LS stands for Lead Screw. INCRA's patented Lead Screw technology makes this unit the leader in precision positioners for woodworking.

The LS positioner's accuracy is +/- 0.05mm - the lead screw's 1mm increments across its entire range, so it's essentially perfect even without the built-in micro adjust. The large micro-adjust knob turns the lead screw against the mating threads, allowing the fence to be shifted in 1/20mm steps to tweak the width of a groove or zero the fence against a router bit.

The fence used for the Standard Systems is the Pro-II 28" fence, which features a surface that's machined flat in a milling machine and a T-slot for adding fixtures or adding the INCRA Wonder Fence in the future. The Pro-II fence directly accepts the Shop Stop or INCRA Stop, and there's also a telescoping extender bar for stopping grooves being cut into longer boards.

INCRA Master Reference Guide & Template Library

Provides straightforward instructions and 51 joinery templates (25 templates in the metric version) to slide into the positioner to provide a visual reference for each joint pattern. Those templates can produce a mind-boggling variety of joints - 11 box joint patterns and 29 dovetail patterns are included (or 9 metric box joints and 16 metric dovetails), and each one of the dovetail patterns can be cut half blind, through, sliding, or corner post.

INCRA Jumbo Right Angle Fixture & INCRA Shop Stop

INCRA's largest Right Angle Fixture is included to keep workpieces square to the fence and square to the table for joinery operations. Instead of the basic stop block of typical router fences, the included INCRA Shop Stop is based on patented incremental positioning racks to give you unparalleled accuracy and repeatability when limiting a board's travel across the router bit, or setting the endpoints of stopped grooves for drawer and box bottoms.

INCRA LS Instructional DVD

The LS systems are topped off with a 1hr, 22min instructional DVD - this great disc is loaded with information - how to take advantage of the optional Wonder Fence's advanced features, cut perfect-fitting rabbets and dadoes, and it has full-length instructions for box joints and the four most common styles of dovetail joints.

INCRA LS17 Positioner

Very sturdy well engineered piece of kit accuracy and repeat ability with this is awesome.Easy to set up would highly recommend

I love it, love it, love it!!!

I first saw this bit of kit online while on holiday overseas and was immediately smitten. I ordered it there and then and it arrived a day so after I arrived back home. Great service, Wood Workers Workshop. Thanks.
I’ve yet to install it to the router table I’m making but already I’m confident that it will meet (even exceed) my expectations! So much so that I’m even going to try rigging it to my saw bench too.
It’s not lightweight, that’s for sure, but this will no doubt enhance its stability in use.
Although it’s not cheap, I think it’s worth every penny. The quality of manufacture is first rate; the repeatable accuracy it promises unprecedented. Moreover, the various templates supplied made my mouth water with anticipation of the complex box and dovetail joints they will enable me to produce.
A master joiner at a stroke!! Can’t wait.
