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

A shopper on Jun 13, 2015
BEST ANSWER: The max radius is 52"
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

SteveBomford on Apr 1, 2016

Very good deal for $, but...
Very good deal for $, but you need to round off the four edges of the dovetail keys a little with sandpaper and then spray a little Top-Cote on it and the Rockler Ellipse Jig will work perfect, beats paying a lot more money. Works best with a plunge router.
July 18, 2008
This is an excellent jig. I...
This is an excellent jig. I have been building fine furniture for years, and you need to use the tool for which it was designed. I took this out of the box, and cut a 36" circle from 1" hard maple. It took 4 passes, but the top came out beautiful. Not done, I then attached a 1" bull-nose bit in my router, and used the circle jig to cut the bull-nose. This is from Rockler, a company who designs tools for the home workshop. Again, stick with using the tool for which it was designed, you will never be disappointed!

I recently bought the ellipse jig...
I recently bought the ellipse jig to use with my Rigid Model 2930 2.25HP plunge router. I routed some oval tables out of plywood with a finished oak veneer surface. I used a half inch spiral upcut bit, which left no splintering. I had no problems attaching the jig to my router and it worked extremely well. You do have to make sure you have a good workbench and that your work and ellipse base are firmly secure. You also have to make sure your router power cord does not get tangled. I was able to consistently route out seven 18x36 inch ovals and was very happy with the results.
June 29, 2011
A good buy
If you need to do circles or an ellipse, this will make it a lot easier. I had to drill holes to fit my router but no big deal. I hooked it up to my Bosch Colt and it did just fine. Did 3 passes with a straight router bit to get to the depth I needed. @ hints I read in the other reviews: 1) a plunge router works best, and 2) find a way to make the slides run easier. I read where some even sanded the corners on the slides to not catch at the crossover. Giving it 4 stars having to drill and countersink the end to fit my router. I have 2 Bosch, Ryobi (a gift) and a Porter Cable. The Porter Cable is dedicated to my router lift on a table and the other 2 are hefty machines. The Colt is light and more than enough to handle the job. Want to use some spiral upcut bits as I think they will do better
October 27, 2014

I bought this jig and last weekend cut my first circle using the jig and my router (EVER). The jig is very easy to use and the table top turned out GREAT. This will make a addition to my shop.
February 8, 2010
I have 2 routers, this item...
I have 2 routers, this item won't fit either, I've tried to send it back, but it will cost way to much, I still have it, just don't seem right.Editor's note: This item is pre-drilled for Porter-Cable 690/890 routers, however it can be used with any router with 6" base footprints by drilling additional holes to match router.
September 3, 2008
I purchased this jig for custom...
I purchased this jig for custom sign shapes for my sign carving business. The instructions were very clear and easy to have for reference right on the jig. After playing around with the jig on some scrap plywood, I gave it a try. I used a 1/2 inch spiral upcut bit in my plunge router and made gradual cuts in 1/4 inch increments. Very easy to use and made a perfect oval! Just take your time and take some practice cuts before you make a formal cut. The jig is very high quality, sturdy and fits my PC 890 series like a glove. I am using it again on a large custom sign and am looking forward to it. Great tool!
September 18, 2012
Works great in theory. Not so...
Works great in theory. Not so well in reality. Fine particles of dust will cause the slides to bind, along with the slides and groves not being precision machined. Slides will stick making the ellipse rough in spots. Extremely difficult to line the router bit with the desired ellipse size. Marking on the arm showing the centerline of the bit would be very helpful. Instructions leave a lot to be desired in these aspects.
November 10, 2007
This product is simple to setup...
This product is simple to setup and I have had very good results. I do recommend that anyone using this jig apply soap to the sliders before cutting to lubricate and ease the movement of the slides through the guide. Once you do this, the jig works wonderfully- if you don't it will be sticky and difficult to move.
November 17, 2007
I have own it for about...
I have own it for about 3 years. This is a great jig , it comes with a 1 1/2" hole that you can use with a brass guide, in that way you don't need to bolt it to your router and the cord will not wind up on you and you can use it on any router you have. But with all oval jigs it has a built in error, but you can over come that by using the magic donuts rings that will take the error out of the jig You will not see the error until you want to make some oval picture frames or mirrors, the narrow parts are thinner but that's the down fall with all oval jigs. If you want to see how to make the donuts or how to use used them with 1 1/2" brass guide go to the routerfoums.com All in all I would say it's a great jig.and well worth the money.
