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!

Pennies ?! Talk about a throwback ! 😅

@JV-pu8kx Год назад

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 Год назад

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 Год назад

@@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.

@dtork47 Год назад

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

Nicely done Marie! That would be a good way to make a picture frame that didn't have 90 degree corners. I made an 8 sided frame many years ago to display a beer mat from a famous pub here in the UK. It would have been easier to cut using this jig.

@augumentum 3 месяца назад

That was very well done. I have a couple of dedicated jigs that have to be adjusted. This setup involves much more precision and less susceptible to angle errors.

hi ,i made your jig. without t-tracks and all the fancy staff here in costa rica it is very hard to find all of those items so i made the sled..with a couple pieses of 1x2 screwed to it got the right angle and i did tasted one by one the angles so easy love it thanks ...very practical ..i do a lot of repeticions so it doesnt matter to me if i have to move the screws ones in a while, thanks for the idea superb.

@papascruffy Год назад

@Robert19637 Год назад

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. :-)

@DIYMontreal Год назад

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

@ObsessiveAboutCats Год назад

This is really cool! As always, your designs are super functional and also good looking (I like the red contrast with the paler wood). I also like the idea of using epoxy instead of screws; I've had some very poor results with screws, and will try epoxy next time. Thanks for the tip. Great video as always. You're awesome!

@stevecopley3017 11 месяцев назад

I like the count er sink you use and in the video said it was in the comments below so had to get my phone because I watch your shows on TV 😂 but after getting the phone I was not able to find it 😢I'm not good with phones so I could use a little help in locating the name of the bit 😊

@stewartbonner 8 месяцев назад

Nobody seems to notice that many 'T' track sizes fit perfectly in the miter slots of table saws.

@harryshaw4998 7 месяцев назад

Where did you get the clamps that have the squeeze trigger??

@janetgorelick 8 месяцев назад

I purchased the plans for this jig but you didn't specify the distance from the fence you placed the board before cutting the kerf and installing the runners. Is this a critical measurement?

@stewartbonner 8 месяцев назад

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.

@williamellis8993 Год назад

Nice and versatile jig, Marie. But shapes other than hexagons? Oh, no (lol)! Bill

@DIYMontreal Год назад

Don't worry, hexagons will always be my favourites :)

@RobertEchten Год назад

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 Год назад

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 Год назад

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.

@Ashevillein Год назад

The size of the polygon is limited though, it seems.or am I not seeing this right?

@michaelramsey3867 4 месяца назад

I am going to purchase the plans for making this Jig. One thing however, the video did not mention how you set the Jig to cut specific sizes of these shapes. I will be cutting 2 inches and 1 inch hexagons for two separate projects. PLEASE ADVISE. Thank you.

@theclosetcarpenter7172 8 месяцев назад

I'm doing something wrong, and I can't figure out what it is! I keep getting triangles!

@doneldridge202 Год назад

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?

@jennyblair331 Год назад

I love the idea of this jig. I'm probably being stupid but how do I set the length of the side of the shape? eg if I want each side to be 2 inches long.

@NukeChiefMech Год назад

Shouldn’t you set the router on two T-tracks in order to set the depth?

@Wordsnwood Год назад

Yup.... @2:10 looks like nickels are the ones! 😁💸

@sdspivey Год назад

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.

@davitolaraia2972 6 месяцев назад

How would I cut a diamond on this jig

@dennisstahlman135 Год назад

🤔🤔🤔🤔 Couldn’t you use som MDF or hardwood to make a setup block. Of course you would Ned one for each shape. Triangle, square, pentagon, hexagon, octagon etc.

@DIYMontreal Год назад

Sure that's always an option, but seemed easier to just have 2 parts that you can adjust.

@dennisstahlman135 Год назад

What meant was to use them to re-set the angles. Put one side against the sawblade to set the first angle and use another side to set the other angle. Kind of like a set up block.

@dennisstahlman135 Год назад

Of course once you have the initial set up, you’re set a block would only need three sides. Find a the blade, side, be the long fence and side see the short fence.

@dennisstahlman135 Год назад

🤔🤷🏻‍♂️😃😂

@stewartbonner 8 месяцев назад

suggest a quick set-up 'square' block or panel, sides at different common angles and the usual drafting triangles. make a shallow storage tray with lid as part of your handhold. Triangle box (staying with the theme) at your close right hand corner.

@axelarge Год назад

If you want to cut other polygons: The angle for a regular polygon with N sides is (N-2)*180/N

Amazing! Thanks for sharing.

Question, it has been many, many years since I was in High School (it feels like it at least) so please tell me if I am correct or if I need to go back to school or not! With the formula that you laid out if I wanted (grab this number out of the sky/clouds) to make a 12 sided Polygon the angle I would need to use would be 150°, is this correct? 🤔 Thank you in advance and I hope you don't think I'm a dumb b@tt for not knowing this off the cuff!!🤔🤔

UHMW is cheap. And it's not worth a crap. Use NYLON, it's more expensive but the results will be worth it. retired tool and die maker. I hated UHMW. I cut a lot of it because the customer was too cheap to use NYLON. It's just not worth the aggravation for the machinists and tool makers to use UHMW.
