I Built a Jig to Cut Large a Ellipse or a Circle / DIY Woodworking

- Опубліковано 25 сер 2024
- I built a jig that can cut a large ellipse or a circle up to 32" in major axis or radius. The concept of the jig similar to other ellipse jib but with a couple of features that help it cut large diameters with stability. I find it useful for three major purposes - to cut an ellipse, to cut elliptical or circular arcs for templates and to cut a circle.

Hello my friend,
It's a great idea. It's now easy to cut circles and elliptical shapes with the router. A great jig. Congratulations. Thank you for sharing. See you. Big greetings. I wish you a healthy and happy weekend. Best regards.
Mehmet....
Thank you so much for the kind words! It was essential for the projects that I'm working on! Now I have more flexibility to build things. You have a great weekend as well!
clever guy. Well done!!
Thank you! It’s been very useful in building some cool things!
Hi. I would like to cut an over with a major axis of about 55 by 30. Do you think this is possible with your jig. If not do you know what I need to change to this jig for this?
You can make the base and the arm larger and should be able to approximately get there. I would set the point and adjust the router arm for major and minor axis than doing the math.
¡¡¡Caramba... Sabes hacer un óvalo!!!
Thanks.
Nice, I mean a jig from unistrut and a couple trolleys. I needed a large possible difference between major and minor axis.
This was really cheap to make and you can extend it quite a bit by simply using a longer board. I think it can get close to 1:2 ratio between minor and major axis. Also you can design more travel for the base that allows the most eccentricity.

Hi how are you great video! I am trying to cut an oval with 180x90 dimensions. Do you know how to set the jig for that?
You setup the jig in the middle and move the router to the minor/major axis points and lock the adjust nuts. You’ll have to do a couple of adjustments but you’ll get it eventually!
How do you keep the two nuts from loosening, that hold small blocks that slide?
It’s a friction fit with holes drilled with a forstner bit. If you feel your fit is too loose you could epoxy it but add an additional washer between the nut and the arm. You should already have a washer between the arm and the wingnut.
What keeps your two blocks from sliding in the slot? Mine loosen about half way around.
The size of of the base define how much your keys slide. If you select a small base but large apogee, the keys slide out. Ideally we should build two or through bases for different size ovals. The recessed slot at the top of the arm keeps the washer fit perfectly and stops from loosening half way through. If your keys are becoming loose, epoxying them should help.
Please send me a photo or video of what your experiencing and I can help troubleshoot. I have gone through a few iterations before landing on recessed slot design so have a few ideas to fix some problems I faced.
@@KiranBhatWoodworking I do not have a recessed slot. If I tighten the wing nuts to keep in position, then it was too tight to move the router. I'll try a recessed slot, thanks.
will this cut a 8x10 oval frame
If you make the radius larger, it should. The principle of cutting oval is the same.
Kiran, have you designed a jig yo cut an ellipse on the bandsaw?
I don’t have a jig to cut ellipse on the band saw. I use the router to make a shallow pass, cut of the excess on band saw and clean up with flush trim bit.
@@KiranBhatWoodworking thx. Looks like that’s the accepted best practice!!
Appreciate the reply
Mareas mucho con la cámara.
