Rockler Large Ellipse Base

This larger base works with the Ellipse/Circle Router Jig (#27712, sold separately) for more design flexibility and ellipses with narrower proportions. The larger size increases the maximum difference between the major and minor axes from 8" to 14". In other words, the maximum length of the major axis remains 52", but the minor axis can be up to 14" shorter than with the standard base.

You Just Have To Know HOW To Make It Work!
Once I figured how to work with the "play" in the slides. I enjoy the increased capacity to make longer ellipses. I made mine easier to work with by creating A MEASURED GRAPH on 3/4 inch ply. Melamine surfaced 4 x 8 creates the best surface to work on. I installed brass threaded inserts for the base and on the four corners of the 4 x 8. As for the "play" that is experienced by some users I use just slight pressure in or out on the router and I get perfect ovals and ellipses every time. Just don't mix pressure during each rotation.

Good Ellipse Base
I have the standard ellipse base, but I needed something larger for a telescope-related project. When I started using the larger ellipse base, I noticed that it had a lot less slop than my old ellipse base. It's made out of the same material as the old base so I suspect after a dozen uses, it will start to get some slop. An aluminum or stainless version would be nice.

The base allowed me to cut...
The base allowed me to cut out the coffee table top I needed but the edges were a little rough. Cleaned up pretty quick with a sander. I wish they had a base that would allow me to make even narrower elipses.

The tolerances are not super which...
The tolerances are not super which shows up when you have to cut a piece in 3-4 passes due to thickness. But 5 minutes with a power sander can clean that up and it is still far better than I could every do by hand. It does stick from time to time in elipse mode, but it you keep one hand on the jig and another on the router then you can make it work. I would buy it again. I do like the big base which helps to open up more design options.

How large of ellipse will this jig make?
s c on Jan 19, 2016
BEST ANSWER: It states on the box how large of an ellipse it'll make. I have both the small and the large one and I am sorry to say that my "honey do" list has gotten in the way of me trying them out. I know the large one states it'll make a2' X4' ellipse. I plan to use it on the tops of my arched doorways.
Does your large ellipse base come with the sliding parts that move through the base?
Shorty on Nov 18, 2015
BEST ANSWER: Yes, it comes with 2 dovetail keys that fit the larger base. One thing to note: the keys on the large base I received were fractionally wider than the keys/small base, maybe 1 to 2 MM. Not sure why they would manufacture them not to be identical. The small keys fit close enough that I wouldn't hesitate to use them on the large base.
Will this fit the Makita RP0900 router?

I need to cut much larger circles for dining tables than any of the sets, if I make my own router base arm, does this item give me everything I need to make circles and elipses with my own router base arm?
Lloyd on Aug 27, 2018
BEST ANSWER: Only if the difference between major&minor axis' is within the specs for the base plate- for instance a table 48"X42" ellipse would work, but a 48"X30" would not, because the pin would slip out of the base plate. You may as well build a base plate out of hardwood to suit your needs, and sliders with screws through the router arm for oversize projects. That said, the rockler product works great for it's size, smooth tracking and easy adjustment
Is there a way to mount the jig w/out having to drill the center hole into your project, two sided tape strong enough?
D S on Jan 17, 2016
BEST ANSWER: I have use the Jag with two-sided tape. But, you need to use a lot of it and be very gentle with spinning the router to make the ellipse. Good luck!

what is the maximum length the minor axis can be?
Tony K on Jan 19, 2016
BEST ANSWER: I don't know off hand, I used it at about 9 inches, I think it can go more.
Actually I have been looking for a smaller one to make frames for pictures of individual .
