It seems someone told AMA you guys wanted a full-size circle, not just a 14ft center circle where the pilots will stand. Well that ain’t going to happen. Unless someone out there has six figures to donate. I’m not interested in going forward with this.

Well, you know things like this go. You mention one little thing, and stuff goes way off on a tangent! I don't know how many circles are laid out in that area, but a 10 foot diameter center pad per circle will be plenty. We restored the center pads for the carrier circle here at Buder Park, if you remember seeing them from you visit last September. The largest one was 9 ft. , made that diameter because that is what the original was, and I think the material costs were in the $500 range, maybe less, and we did the work. Well, some of us did! The parks department was only worried about mowing the grass and didn't want anything high above the grass. We laid out the forms to be about 6 inches above the surrounding grade, put a piece of pipe in the center to match that elevation or a fuzz higher, put gravel in the base up to the bottom of the anticipated 4" thick pad, then poured concrete, mixing 80 pound bags of QuickCrete as we went using a rented mixer. You could put some re-enforcing wire in it if you want but note really necessary for people to stand on it. Used a 2 by 4 to strike off the cement even with the tops of the forms and the center pipe, troweled that a little bit, edged it with an edger when it was ready, then broomed it off a bit. When we took the forms off a week or so later, we back filled with dirt up to the edge of the pad and raked that level out to about 4 or 5 feet from the edge of the pad. Grass grew back, they can mow right over the edge, and water doesn't puddle on it. It's a simple process as long as you don't have too many chiefs and not enough Indians! Something like this can be done pretty cheaply even hiring out the job
Type at you later,
