The Rockler Ellipse/Circle Router Jig lets you cut circles and ellipse shapes over a wide range of dimensions and proportions. With your router and this handy, easy-to-use jig, you'll be able to make picture frames, mirrors, signs, tabletops and more in just a matter of minutes. Compare to other ellipse/circle router jigs that cost $100 more. Set up takes only a couple of minutes and is virtually math-free. Using the jig is just as easy. As you move the router through the cut, the jig's sliding dovetail mechanism keeps the router precisely on the cut line. Designed for use with just about any plunge router.

One thing to be aware of...
One thing to be aware of when considering this product is, as stated on the packaging, "Maximum difference between minor and major axis is 8 inches" As long as you're okay with that, it's a great product. Very happy with my purchase.

it works very well, and the operation is simple but instructions aren't very good. one thing I learned, use one hand to operate the router and the other to hold down the opposite end of the jig. .

what is the smallest minor axis and major axis the elliptical jig can make?
JIM D on Oct 30, 2015
will this work without a plunge router?
A shopper on Aug 8, 2015
BEST ANSWER: I would not do so..a plunge would be best.. I'm sure people have tried to hold down the small end with the pin, and lift up the router off the surface and turn it on & put it down again, but that would scare me silly. Be safe, use a plunge router.

Rob W on Apr 18, 2016
BEST ANSWER: You could make another larger plate out of plexiglass

How do I cut circles? There are no directions or instructions with the jig.
riverbum on Jul 10, 2016
BEST ANSWER: To cut a circle with this jig you only use one of the sliding pins and fasten it down in the center with screws. On this page of our website you can find the instructions on the right hand side of the page just down from the top a bit under the header of Technical Downloads. The last square show how to cut circles.
What size / style bit are people using with this jig?
Mark Z on May 16, 2016
BEST ANSWER: All of my bits are 1/2 inch shank and if I am just cutting a circle I use a straight bit anywhere from 1/4 to 1/2 inch in diameter. I have found that if the material that I am cutting is more than 1/2 inch thick, I make cuts in several different depths. It is much easier on the router bit and prevents burns in hard wood.
Interested in purchasing this product, I'm new to woodworking have a bosch router but wondering what type of router bit you would use to cut wood out with?
Christopher L on Mar 4, 2016
BEST ANSWER: A small diameter straight bit. Be sure to make several passes, at least two to three, depending on the material thickness. Good luck

can i use a regular router or does it have to be a plunge router? I don't have a plunge router.
Laurence J on Jan 28, 2018
BEST ANSWER: Read the list of compatibile routers. I had 4 different routers and I thought one of mine would match the pre-drilled holes. I had to buy a new one, which I don’t mind, less bits and tools to change out. If the holes match and you can adjust the depth of your cut, it will work. For a clean cut you need to be able to take it in small increments to avoid tear out. Theoretically you could re-drill the holes in the jig to fit your router, but unless you are spot on, your cut will be off. Best bet is to have a router off the compatibility list in the description.
will it make a 24x48 in. eclipse table top?
David on Jan 23, 2018

Are the T-bolts hollowed out so they fit over the pins? What keeps the T-bolts from popping up off the pins? Thanks
Mike G on May 11, 2017
BEST ANSWER: T bolts have a chamfer to allow bolt to lay flush in the T block which I believe is threaded. I absolutely love this jig especially for use in oval frames or large diameters. I have built my own in the past but it didn't near as smooth as this! Thx Hope this helps!!

Look @ "Gregory Custom Woodworking" on Facebook
