The MagJig and the Incra Fence

I had an idea a while ago as soon as I saw the MagJig by MagSwitch – this has the potential to a problem that has perplexed me for ages. How do I get in incredible accuracy of the Incra LS Positioner fence on the Triton?

The problem was always fixing the fence down well enough to use the fence accurately, yet able to be removed easily, and without damaging the Triton top (ie drilling holes etc). Now that I also have a cast-iron cabinet saw, it also provided the perfect solution for using the Incra fence on that as well (and there is NO way I’m drilling holes into that top!!)

So off to the drill press, and a couple of 40mm diameter holes later, and the MagJigs inserted, we have a perfect solution.

The LS Positioner secured firmly to the tabletop. Now, to qualify the photo, I have removed the vertical panel support from the LS Positioner, but I have not removed the Wonderfence, which you certainly would before using the LS Positioner on the tablesaw.

Secondly, I would definitely use the Deluxe Aligner to ensure the fence was perfectly parallel with the blade (or more precisely with the mitre slot in the table.

The Deluxe Aligner is perfect for the task. (Obviously this is a photo from my file, and is not aligning the fence!!)

Finally, and one of the great things about the Incra LS Positioner is once it is set up and parallel to the blade, it is an absolute cinch to zero the fence to the blade, allowing extremely accurate cuts to be made. You’d definitely want to ensure an absolute minimum of blade runout, because the LS Positioner will give 1/1000th of an inch accuracy to your cuts!

And just to prove a point, here it is on the Triton, turning it into a precision machine!

There will definitely be more posts / video on this in the future – the possibilities are too good not to explore this further. (Again, if this was actually about to be used, the Wonderfence would be removed leaving the straight fence only). Attaching a false (MDF) fence to that would then allow the blade to be partially buried in the fence for shaving cuts, or the use of a dado blade (but not on the Triton obviously!)
