Hah! Now all I need to do is figure out how to draw an arc with an 18 foot radius :-) I have a couple of ideas and will post pix of the process.


Two lengths of PVC pipe. Drill a hole in one end, attach a pencil to
the other at 18'. Draw the arc on the ground, spiking the pivot end in
the ground and putting the wood at the pencil end.
