   Here's a resized JPG of the file to make it more palatable.  I'll look around for the formula to find that sort of stuff, I've got it somewhere.

   Place nails on the end points, and a nail on the high point on each board you want to cut.

   Attach two crossing laths or sticks together,on left and top/and right and top (picture a chevron) nails.

   Take out the top nail, and scribe the arc that the chevron describes, as you swing the guide (chevron) from end point to end point.

   That make any sense?...

   It probably makes perfect sense, but I'm not grasping it. ; ^ )

   Thanks for the tip though. Those other sites are gonna help me.                            Mike

   radius of a circle with a chord 13' long, segment above chord 1' high: 21.625'

   radius of a circle with a chord 9.5' long (half of 19'), segment 1': 11.781'

   radius of a circle with a chord 11' long, segment 1' high: 15.625'

   Hope that helps.  I got it from this site: http://www.1728.com/circsect.htm

   Ruffmike: Try this Circular Arch Calculator.

   Click here for links to more Circle Calculators.

   There's an explanation of the theory and diagrams with most of the calculators in case you want to make notes to use on-site in future.

   If you change your mind and would rather use elliptic or other strange and weird curves rather than circles give me a shout.

   Hope this helps. :)

   Thanks for the link. Just what I needed.

   I see you are coming to the Bay Area. If you stick around long enough, they MIGHT get started on the suspension section of the Bay Bridge.

   I'm in Alameda if you want to see the fence.                            Mike

   Maybe I'll come by and check it out sometime.  I'm moving to albany/berkeley in 2 weeks.

   I wouldn't mind getting a job on that bay bridge, but I think it's too far off for me.  I prefer to work in small groups anyway, and I get the feeling that would be big time.zak

   I'm commuting to the city now and as nice as it would be to say "I built that bridge", its just too dangerous to consider.

   My carpenters local's logo is the Bay Bridge, I guess that's as close as I'll get.                            Mike

   It's a sine curve, Ruff.

   Or a cosine curve, Mike.

   Whichever, get out your old trig calculator, the one they made you buy back in ninth grade, get some new batteries, and figure it out.

   The exercise will do you good.

   I cannot find the key for a parbola on my old calculator.

   Punching in "PAR" on my cellphone brings out the paramedics, and I am not in need of any right now, thank you.

   Maybe I'll put a parabolic gothic tip on the pickets. ; ^ )                            Mike

   Looks like you need to assemble this fence with the pickets running wild. Then lay out your pattern until you like it. The nail deal will work great. Then when you are finally happy, Cut that "Sons O Biatch" before you change your mind.
