Mathmatical question.?
I don't want it to form a "V", but a half circle. How do I determine how long to cut each lattice board?
I hope this is enough info. Let me know if you need more details.
Thank you.
Answer:
Few ways i can think of. First would be to use cad software and draw it out. Next would be to use trig and few hours. Last Get some string, roll of paper go out side and use a pen and that string to draw out the arc. Next measure everything you need.
But then again you know someone around here must have the math formula to do it hehe :) In most cases when this is done they don't precut the wood, they put it up then draw a arc and cut it :)
It might be easier NOT to try and figure out the math from a practical perspective. Ive seen carpenters nail the boards down as they are and let the boards "hang long". Then, they take a string that has a pencil attached to one end and keep the other end fixed about where the center of your circle is. Imagine nailing a string down (fixed to some point) in the middle of your patio roof and walking around the point in a circle. With this free end, layout where you will cut it (this might take a couple tries until you get the mark where you want it...now can use a saw to cut out your arc.
