DIY LOUVER SHUTTER JIG

Jig to make perfectly spaced slots for louver slats on a table saw with a dado blade.
The other video I’ve seen show trying to match the angled slots by using a positioning pin on both sides. The problem is that if those pins are off by just a few thousands, after a number of slots, they will not match. I’m registering the second set of slots off the first slots that were cut, ending up with perfectly matched left and right slots.
Of course when you have the slot strips cut, you can glue or finish nail them into the door or shutter frame.
If you have any questions I will be glad to answer.
