Hi folks,

Does anyone have a tip on making an oval tabletop? Size: 68" wide, by 74" long. I'm thinking the must be a jig or a method to create the oval.

 

thx

Limbert style coffee table is oval (post #170874, reply #1 of 7)

I haven't tried it, but here is the link to the FWW article where Greg Paolini made a coffee table that was oval.  He made a template first.

There are several sites you can go to try Tackling Large Table tops in Projects This might help you get the idea. Good Luck

   Hi Don,

           I'm guessing you are making a solid top ?

        There are many ways to create the ellipse or oval , one is to use 2 fixed points with a string and a pencil .

       I typically make a quarter template yours would be 34" X 37" , I use a thin  strip of 1/4" mdf to make the curve ,band saw and sand it out smooth .

      flip it and draw the whole oval or create a full size template which I don't do unless I am making an oval frame .

                  hope this helps good luck

Something is triggering a spam filter, so I am paring this down.  Try a superellipse. Google "superellipse" and tons of articles will show up for it, including Wikipedia. 


The superellipse is characterized by |x/a|^n + |y/b|^n = 1, with n>2.  When n=2 we have, of course, the conventional ellipse.  It tucks nicely into corners more tightly than a conventional n=2 ellipse, yet it has a continuity of changing curvature that is pleasing to the eye.

Ellipse (post #170874, reply #6 of 7)

I will address layout only. Draw a line 74" long, draw a perpendicular at the center of this line 34" high. Set your trammels at 37" radius and place the point at the top of the perpendicular, strike two intersects on the 74" line. Drive two nails into these intersects, drive another nail into the top of the 34" line. Strech a line around the nails tying it to the two on the 74" line, pull out the nail at the top of the perpendicular, place a pencil inside the line and scribe an elipse around the two points. The trick is to find string that will not stretch, I used to use the waxed string used to tie parcels, but maybe monofiliment would work. Been a long time since I have used this method so test it first....
