I started a new project I have never done before, a 42 inch round dining table. I built a circle jig for my router I thought I would use but its a bit loose at the pivot not to mention I don't own a bit to do 2 inch thick top. I decided to use my table saw. I started with a 44 by 50 ish glue up. drilled a 1/8 inch hole very shallow in the bottom side of the table top. layed out the circle with a pencil and a board half the diameter, shaved it close with a skilsaw. then I drilled a hole on the workbench and screwed a screw from the bottom until sticking through 1/4 inch. I set the table top hole on the screw and scooted the saw close started sawing off the rough edged. one more move to the final dimensions and sawed the final cut. it came out really clean.

That is a good way to make a clean circle; nice job.
I don't believe I would have ever thought of that method. I constantly learn something new from you experts. Great job. Looks like a pretty good circle cut.
Nice. I saw a similar approach on a video a while back - seems like a great method. I used a router a while back to cut a circle in a laminated platform and it was a pain. I cut from both sides since it was so thick and the result was a slightly misaligned cut that needed a lot of cleanup. I'll definitely be keeping this in mind for future projects :)
Brilliant 8) Is your bench exactly the same height as the saw table?

yes within fractions of an inch. it was purposefully built that way. I used a plywood top for just such occasions. it becomes the sacrifice rather than drilling a really nice workbench top. I don't mind drilling through it or screwing to it or other bad habits. I will add to this that you have to shave it down pretty close, more than a 1/4 inch and it didn't want to shave off even. I started back from the line and worked to the line. 3 revolutions and it was done though.

Those aren't bad habits, that's what a workbench is for! Nice work on the jig :)
Made thousands of plywood circles in my youth in a similar manner, but we used a bandsaw. We'd cut blanks 1 inch oversized in each dimension, then start the cut into the center of one edge. Had a pointed nail protruding through an auxiliary, clamped on wooden table. Start the cut, then smack the blank down onto the nail with your fist, and cut the circle. They were for a chemical company that used them to seal flanges on large pipes during maintenance.

Very nicely done.
Looks great!
You can make circles with a table saw without trimming it close by starting with the blade low and raising it a bit after each turn, I suspect it would take a while doing this with thick material like you have but perhaps a combination of both methods would work.
Is that Cedar? :D
That is outstanding! :)
Hilltop, my tablesaw is such a bear to rsise and lower. its always bound up. A ryobi design flaw and on the hope to replace soon list.
Poston, its cedar. Its always cedar here.
Thanks Jeff.
Now I need to make a steam chamber so I can live edge wrap one 8)
You are very right about the ryobi having blade adjustment flaws. I constantly had troubles with mine. I got pretty good at taking it apart to clean the races. The trunion was another sore spot. I still have mine but sure am glad I bought something else.
pretty table, love the design, nice work larry,
Nice work that looks great!
Great Job Yukon love the set!
Liked the change to your avatar/ picture. Great automation by Jeff!
Yukon, you are becoming quite a craftsman. I love your adventurous attitude. 8)
Very nice looking table and chairs. Looks like it would be a great poker table.
