adjustable circle jig suggestion

1804 Views 10 Replies 6 Participants Last post by  4DThinker
I'm in need of a basic adjustable circle jig for my new foray into routing. I've looked at a few videos.

I liked this one

But I don't have the planing router bit. Nor the steel piece & tap setup. Ideally just a knobbed screw top that that taps into the piece below with a dowel like pin to pivot.

Could someone recommend one, preferably with an instructional video?

Keep it simple. Many folks use something like this here If you end up doing a lot of circles a more elaborate one can be made or bought

I suppose that design would work. Just making different pivot points as needed.

As you said, until I need it more than the initial few circles.

Thanks
It is easy to make a simple circle jig. There are many posts on the forum and youtube on various designs.

Or buy a Jasper 200 jig. Should last you forever.....

At that price range, I don't see much reason to make my own (multiple times over the years). I should just get the 200J.

Just what kind of info i needed. Thanks!

In the first video that jig will cut a circle down to 1/2 inch in diameter, if you are very careful and modify it a little. I made that or one similar and it works very well. Just my two cents.

Making your own from masonite IS pretty easy. But I had more money than time.

I was the same, Tom, when I was working....LOL.

Now retired, so have more time than money.

I, at the time, purchased 2 Jasper jigs, an Oak Park jig, a Rockler? circle jig and an elipse jig......(and also made at least one like the one @harrysin demonstated)))

I initially bought the 200j without using my brain to realize it was too small for my needs. So I ordered the 300 Pro. And we finally had a warm weekend day for me to give it a try.

So easy to use.

I had already opened the 200j and scuffed it up. So I didn't try to return it. And that's a good thing since the 300 Pro doesn't come with any pins or screws for attaching to the router.

I've got a couple router tables, and more than a couple routers. I also have a bandsaw and have always made perfect circles with a simple fixture slid onto and clamped to the bandsaw table. A stick to hold up the outboard end. I made a nearly matching fixture that could then spin to sand the same circle edge on my disk sander. Not always needed as the bandsaw blade and a slow steady feed could usually make a nice smooth edge.
