I had some circles to cut out of plywood so I built a sled with out a fence for my new tablesaw. the backgroundnoise in the video is bad because of the saw, and the dust collection going. What I was saying in the video was take light cuts while spinning the circle piece into the blade than advace the sled, and spin the piece again until no more material is being removed, than the piece is completed. I like the router for large circles, but for smaller circles I like the tablesaw the circles are accurate, and the finish is smooth.

Hope you enjoy the video.

did I just see you drill into the top of your tablesaw?

oh good. Looked like you took the drill and drilled right on top of the tablesaw. I mean that is of course your choice, but glad to hear my eyes deceived me :)

the circles turned out nice. I have not tried it on the table saw, but did make a similar jig for the router table. the finish looks smooth. great job!

We use a similar technique at a cabinet shop to do circles for lazy susans. Never get are hands that close to the blade. Many will appreciate seeing another way to make rounds but I believe a safer way to make smaller rounds is with a bandsaw if they have one. I’m not trying to be critical of your demonstration as I appreciate all that I learn from others here. I just believe that a tablesaw is a lot less forgiving than a bandsaw from a safety standpoint. The same technique you used here can be applied to a bandsaw. Thanks for the tip and keep them coming.

I remembered this post and I was hoping I could find it again. I have a really sorry craftsman router table and a worse free hand router. I don’t own a bandsaw either.

I just cut some beautiful circles with this method. I want to thank you for posting. I’ll link this post to my project when I’m finished.

-- Thanks for all the lessons!

That is pretty slick. I was worried watching the little pieces being knocked away with that short pencil. Also when the part was removed with the blade running. If that blade would have caught the edge, It could be thrown at you. One suggestion would be to have a way to lock the sled in place while turning the piece so you don’t have to worry about holding it at just the right cutting point while doing the turning.

I guess I just am too cautious around a table saw when you have to get you fingers too close. I have the utmost respect for that machine!!
