Parallel Guide for K3 Slider – version II




I have a short stroke Hammer K3 slider (wagon is 1250 long). The wagon is used with a reversed Fritz and Frans jig (as the crosscut fence is at the start of the wagon). This pushes against the crosscut fence and locks in place ...



Or I have used a parallel guide, such as this ...

This is what I came up with ...








The fence along with the stop, which can be used or removed ...



My aim is the use the parallel guide in conjunction with the crosscut fence. The parallel guide is set up square to the blade and, like the stop on the crosscut fence, it can be set at a specific distance. 



The maximum setting distance from the blade is 500mm.

The underside of the parallel guide: tracks made of UHMW  ...



The rear Perspex guides double as a position locater ..





Everything is adjustable. Below, the fence is adjusted for parallel by the side screws ...



Steel angle brackets are used to connect the base to the wagon. The L-bracket on the underside ensures the base is square. This is also adjustable ...
