The Polygon Jig | Cut any shape on the table saw (plans available)

Рет қаралды 71,202

Күн бұрын

A couple years ago I built a hexagon cutting jig. It's adjustable and can cut out hexagons any size. I have plans available for this jig but I get a lot of requests for either a pentagon jig or an octagon jig. So today, instead of building a dedicated jig for each shape, I'm building a polygon cutting jig. With this geometric jig, you can cut any shape you want! One jig that does it all. Cut a pentagon, hexagon, octagon or even a heptagon. Get the plans below!

Tip #1: put a stop on the underside of the jig so that it will hit the front edge of the saw and you will never have to worry about the kerf growing. Tip #2: save samples of each shape to speed subsequent setups.

@DIYMontreal Жыл бұрын

I like tip #2 but not sure I get tip 1. How can I put a stop underside of the jig? Genuinely curious as I though about whether or not to add a bridge but decided not to as it might get in the way when cutting larger shapes.

@JV-pu8kx Жыл бұрын

@@DIYMontreal A strip of wood, plastic, or metal, along one edge (closest to the operator), perpendicular to the runners. Depending on how thick you make it, It will be hitting the front edge of the table or the fence rail. Think of an upside-down miter gage, a bench hook, or a simple miterbox and how they hook onto the workbench. Sorry, I don't have any visuals for you.

Improved for sure by having a stop to prolong the lift of the gauge…….great idea! Wonder about a length of piece gauge that could run in the slot right of the blade, for cutting those segmented pieces for us turners? Howdy from MT USA

Hi Marie. Nice work you have there. Thanks for the nice videos you send out. I have a suggestion for how you can avoid cutting into those who lead the subject. Set up a stop at the end of your saw so the blade doesn't reach too far forward. Hope you understand what I mean. :-)

Like a magswitch or something to stop the sled from going to far forward and cutting through the fence? Yeah great idea!

@RobertEchten Жыл бұрын

Awesome jig! What do you suggest as the best way to get the correct length for the sides? Measure from the kerf of the first cut and align the second fence to that or is there a quicker/better/more accurate way in your experience. You can make a sample of each shape and then instead of using the protractor use that sample to set the correct angle for that particular polygon.

@DIYMontreal Жыл бұрын

Once the back fence is set, you can use the ruler on the protractor to get the size you want one side to be. Beyond that I think practice and having templates as you suggested.

@sdspivey Жыл бұрын

Make the first cut, then measure and mark on the piece where the next cut should go. All the rest will be the same length.

@jimbrooks1452 Ай бұрын

High school Geometry teacher here. The cheat sheet is fine, but limiting. To find the angle for any regular polygon (a polygon with equal sides and equal angles) of n sides, use 180(n-2) then divide this number by the number sides. For example, what angle for a hexagon? A hexagon has 6 sides, so n=6. Here we go: 180(6-2)=720, and 720/6=120. So, set your jig to 120 (of which you did). What if for some reason you wanted to make a 12 sided polygon? In this case, n=12; 180(12-2)=1800; and 1800/12=150. Set the jig to 150 degree and you will get a regular dodecagon! BTW, very nicely done.

Hi Marie...I'm not sure if I missed it or if it is obvious and I am still missing it but if I need a polygon a specific size how do I determine the setting of the guides? Do I find the center of my blank to the first cut and set the center half the distance of the finish height away from the blade?

@sdspivey Жыл бұрын

Running a dado with the table saw for the metal guides would have been faster, safer, and more accurate. Instead of a chamfer, add a bunch of .25"x.25" dados under the runners, about an inch or so apart. With thinner boards, the chamfer will mess up your measurements, where the small dados will allow chips to get out of the way, while still fully supporting the board. Also, always leave a decent gap between the runners, for additional chip removal. Get a set of cheap plastic drafting triangles. Even the cheapest will be remarkably accurate and you can use them to set the angles for hexagons (60°), octagons (45°), and dodecagons (30°) much better than the protractor. You just have to place the triangle on the other side of the blade. For a pentagon, once you make one "perfectly", save it for setting up the angle next time.

No need for the second fence end to butt up against the first fence. Just collects debris. The workpiece is registering on the fence edge, the the second fence end is not involved in alignment.
