Ed,

Allowing for distortion on the computer screen, yours looks pretty close to the original. I'm sorry I'm not more computer literate, or I'd have drawn something in one of those sexy design programs...except I don't have any of those programs.

My choice early in life was either to be a piano-player in a whorehouse or a politician. And to tell the truth, there's hardly any difference.

I bet they did something silly like I do

when confronted with such problems.

I just take a piece of paper of appropriate

size and draw a corner till it looks

right to me. Then I make a pattern

from the paper onto some poster board.

I know this is a simple solution for the

tech savy crowd. Sometimes the simple

way is the easiest way. Least wise it

has always served me well.

I think 90 looks about right, the others don't seem like they will look right with the straps. Just my visual opinion.

Hey Ed,

I agree with Jordan. I think 90 is excellent!

I agree with Windy and Mike...

I think there are two different radius'. I also think they just winged it by making a paper patter starting the vertical and the horizontal with one radius and filling in the two with a different radius. I made a quick paper pattern and used two different radius'... one was a cork stopper for where the curves first start, the other was the bottom of my RM Williams conditioner can (is there anything RM Williams isn't good for?). You can see how the two have been blended together. The other line is how a single radius would have wound up had I only used the RM Williams can.

Thanks Darc. Now I understand what Mike was saying. After all this, we now have three methods for cutting these curves.

1. Freehand. Art and Windy told me about this a year or two ago, and is the method for how I've been shaping my flaps.

2. Find a picture of the curve you like, get a rough estimate of the ratio of where the arcs begin on the x and y , axes , position a plate or saucer of similar diameter, etch your curve, and cut.

3. Use the two radii blended together.
