Hello All,
Great discusssion here, even the mistakes help to make this clearer when explained. Something no one has mentioned yet, is there a curve in your grade? Your level tool will not work. It will show a higher grade than you actually have. To calculate the length of your curve you need to use 2 X pie (3.14) X Radius.
A 30" curve has a circumference of 188.4" (distance around the complete circle)
2 X 3.14 x 30 = 188.4"
How much of that curve are you laying?
Half circle is 50% X 188.4" = 94.2" of distance
Quarter circle is 25% X 188.4" = 47.1" of distance
Eighth of a circle is 12.5% X 188.4" = 27.55"
Just my two cents.
I never knew you could multiply by a pastry. I did know that you could multiply by pi though.
Sorry, I couldn't help myself. =D
