Kato already sells 19" radius track.  I don't remember them selling 21" radius, though.  I think their next step radius is 28".

I'm making a basic oval,if I used the 19 inch radius curves Atlas Code 80 pieces would 1 pack of 6 pieces make a half circle?Stupid question,sorry but I can get it at a better price on line.I'm thinking of using flex track as my straight sections with my bridges.

It’s not a stupid question.  I just looked at the snap track curves and nowhere can I see what degree of a circle they are.  They have a full and a half section of curves. But, and I’m guessing here, it does appear that the full sections are 30 degrees and the half’s are 15 degrees.  If I’m right on this assumption then a six pack of the full sections would make a 180 degree turn or half a circle.

That is correct.

Thank you for you're answer.I believe they are about 5 inches long per piece.I'm going to use the string and pencil method and draw the radius then go from there.There was another answer backing yours so I can place my order.

An easier and more versatile way is to get a big piece of scrap card board and make a template (180 degrees) of the radius(i) you are planning on using.  Much easier to position and play "what-if" than a string and pencil method.

Yep. That’s a good method too that I have also used in the past, but I still needed the string/nail/pencil to draw he template. 😁

Hold up. Just found this.   https://support.modeltrainstuff.com/hc/en-us/articles/202970193-How-many-pieces-of-track-do-you-need-to-make-a-circle-

For the 19” radius code 80 it appears you need 24 pieces for a circle.
