How can I use a router to cut small "rings" out of 3/4 inch hardwood. Typical ring would be Inner diameter of 1" and outer diameter of 2 1/2".
I did consider two hole saws Bj. but discarded the idea because a 2 1/2" high quality bi-metal hole saw isn't cheap and the low cost Asian hole saws would find it hard work to make multiple rings in 3/4" hardwood. But I did say that there were different ways to achieve the desired result, let us stand by for further ideas.
As you said, a 1" plug is rather small for routing but certainly possible by making a simple crude jig consisting of no more than a strip of Acrylic or even thin MDF fixed to the base of the router with a panel pin going through it exactly 1" from the edge of the cutter. The pin is tapped into the material and the router rotated around it. I made the jig shown about 7 years ago, it was designed by a fellow member and is as good as they get in as much as it is infinitely variable, most jigs go up in fixed increments. Like you, I have never had a perfect result from a hole saw, they're fine for making holes in cabinets for cables the pass through and that's about it for me.Harry,
What, no pictures with the circle cutting jig? A very important piece me thinks.
Your idea of the center plug solved my question. I wouldn't have thought of that. You can make that plug with the circle cutter on the router too although under an inch might not be advised. Great thing is you don't have to buy any additional tools as long as you have the router (I assume we all do since we're on this board) and a straight bit. You can even make the circle cutting jig yourself.
My problem using the hole saws is that I have never had a decent finish on the cut even when I cut it from both sides. Plus the material always has a nasty habit of getting lodged in place.
in·vid·i·ousTom, I'm in an invidious position, I'm friends with everyone and some understand metric, others only imperial and still others both,so I choose whichever I think will best suit the recipient. I know Tom, I'm one hell of a Mr. nice guy, I just can't help it!
Hi crquack:This is probably well past the date of interest but Lee Valley sell an excellent small circle jig. I use it with success. I am not allowed to post links yet but their web site is easily searched.
