This is the latest application of the method I have settled on for these things. This one gets multiple fence positions and a 45* fence instead of a triangle that attaches to the 90* fence. The "hook" is also moved up from the end by about 2-1/2". This is more comfortable for me based on my height, reach, etc.
Simple and quick to make (LV track not required but, really nice Xmas gift). I have found that it is nice to have a little wiggle room now and again so I have moved that feature forward onto this version. I make my 90* fence adjustable about a degree each way and the 45* fence adjustable a couple of degrees each way. The knob and fender washer keep the fence put once set until I change it.
