TheJackal Posted April 6, 2013 Share Posted April 6, 2013 A arch made from 8-100 count strings wrapped on 3/4" conduit will be approximately 10' long (give or take a little bit). Arched in a perfect arch it will be 3.18' wide? I need this number so I know how/where to set up my arches. 10' = 1/2 circle20' = complete circleCircumference = 2(3.14)R20' = 2(3.14)R20'/6.28 = R3.18' = R Link to comment Share on other sites More sharing options...
viennaxmas Posted April 6, 2013 Share Posted April 6, 2013 To get the width I think you would need the diameter which is 2 R - so 6.36... Link to comment Share on other sites More sharing options...

Shubb Posted April 6, 2013 Share Posted April 6, 2013 My 7 channel, 100 count mini's on 3/4" pipe are 7 feet long. I use a smaller radius so they are space about 4.5 feet apart.The arch's that start out straight up don't look right to me.Just my opinion. Try out a few different lengths till you get what looks good to you. Scott Link to comment Share on other sites More sharing options...
TheJackal Posted April 6, 2013 Author Share Posted April 6, 2013 (edited) My 7 channel, 100 count mini's on 3/4" pipe are 7 feet long.

Try out a few different lengths till you get what looks good to you. ScottLooks like 1 string around a 3/4" pipe = 1 foot. I planned on dedicating 1 controller for 4 - 8 string arches (each channel controlling 2 strings, arches 1+3, arches 2+4, if that makes sense). Just took measurements in my yard and its borderline on whether this would work. I'm wondering if 4 - 4 string arches would look good? THAT would fit my yard better. I don't see any video of these. I'm also thinking of 2014, which will most likely have more controllers. I'm trying to keep the numbers even with the controllers 4-8-16 etc Edited April 6, 2013 by TheJackal Link to comment Share on other sites More sharing options...
Steven Posted April 6, 2013 Share Posted April 6, 2013 The arch's that start out straight up don't look right to me.I agree. Most arches are more than twice as wide as they are high. For instance, my mega-arch is 49 feet long and 30 feet wide. (I haven't measured the height.) Using the same ratio, a 10-foot arch would be about 6 feet wide. I'm wondering if 4 - 4 string arches would look good?In my opinion, it would be better to duplicate 8-channel arches, as you are planning. Then you could use the same arches in the future when you get more controllers. 1 Link to comment Share on other sites More sharing options...
Shubb Posted April 6, 2013 Share Posted April 6, 2013 Depending on the bulb spacing you will vary between 10" and 14" per 100 count. I found that the bulbs were starting to line up on one side of the arch if we wrapped them tight. So every few turns we doubled back on the string to keep the bulb spacing semi-random. If you want to keep the spacing of each section exact it doesn't hurt to have a few wraps overlapping if you have some extra string left. As far as sections, 4-100 count sections are a little "choppy" If you are short on channels I would go with 6 or 7 per arch and piggy back another arch onto the same channels. They would be duplicates, but would look much smoother. Link to comment Share on other sites More sharing options...
Ken Benedict Posted April 6, 2013 Share Posted April 6, 2013 Complete circumference is Pi * Diameter; half of that would be a hoop. Go from there. Link to comment Share on other sites More sharing options...

Also, I started thinking the 4-4's would be TO small...unless I had a whole bunch of them. Maybe next year. Thx. Complete circumference is Pi * Diameter; half of that would be a hoop.

LightsinMaine Posted April 7, 2013 Share Posted April 7, 2013 I feel the same...my arches at 3.5' high and 7' wide....I'm not a fan of arches that start going straight up (but it might be what u want, nothing wrong doing something different than others) Link to comment Share on other sites More sharing options...
Joe Polenchar Posted April 7, 2013 Share Posted April 7, 2013 I use 5 and 7 channel arches. 100 count c6 leds per section.7ft between the legs about 3 to 3.5 ft tall. This gives me a very smooth arch.Odd number of channels per arch make them flow much smoother.The odd segment is dead center on the arch. Just my thoughts.

jimswinder Posted April 8, 2013 Share Posted April 8, 2013 I have NO spacing between my arches...so on a chase, it can look as though it is continuous flow from one arch to the next... Link to comment Share on other sites More sharing options...
Joe Polenchar Posted April 8, 2013 Share Posted April 8, 2013 I agree with Jim. Next to no space between arches.You want as smooth of a flow as you can get. Link to comment Share on other sites More sharing options...
