Ron Boyd Posted May 25, 2012 Share Posted May 25, 2012 I'm creating a Marty Fan from PVC and CORO. Does anyone know a formula or the equation to get the lines equal on the following drawing. It will be 16 channels.I came up with 8" apart, but when I mark them, one side at the bottom keeps coming up low. Any thoughts?Thanks,Ron Attached files Link to comment Share on other sites More sharing options...
Guest guest Posted May 25, 2012 Share Posted May 25, 2012 I've never built a marty fan, but, based on your drawing, you have 17 spaces in 128 inches. 128/17=7.53, so if you space 8 inches, but the time you get to the last "space" you'll have less than 7-1/2 inches to work with.Back off about a 1/2 inch on each space and seems like you should be fine.

I tried spacing at 8" and I was coming up short on the last one. Thanks, I'll try your solution when I get home this evening. Link to comment Share on other sites More sharing options...

So 128 inches / 15 spaces = 8.53 inches per spaceThat 8.53 inches is the arc distance along the PVC.Rounding down to 8.5" will leave you 1/4" short on each side.... close enough for government work.

Brian Mitchell Posted May 25, 2012 Share Posted May 25, 2012 When measuring your spaces, start at top center and measure outwards. That will keep your spacing even side to side. Link to comment Share on other sites More sharing options...

Don't forget the two spaces below strands 1 and 16--15+2=17. Assuming the picture is accurate, you need to account for 17 spaces. Link to comment Share on other sites More sharing options...

jimswinder Posted May 25, 2012 Share Posted May 25, 2012 it could be 15 spaces or 17 spaces...all depends if two of the strings are parallel to the ground and are his starting and ending strings... Link to comment Share on other sites More sharing options...
Guest guest Posted May 25, 2012 Share Posted May 25, 2012 True. I'm assuming the picture is an accurate depiction of what he is trying to do, especially since there are 16 fan "strings" shown. What arnold is showing is correct. Link to comment Share on other sites More sharing options...
LORi P Posted May 25, 2012 Share Posted May 25, 2012 Guys, it seems like Jim is the only one who 'gets' me. *sigh* I was assuming that he wants 16 channels spread across the whole half circle of the fan. One string in the 9 o'clock position. And one string in the 3 o'clock position. And the remaining 14 strings spread evenly from 9 to 3. 15 'spaces' each space being 8.5".Again, I was assuming that he wanted to get rid of the small gaps he had between 'horizontal' and his first and last strings. I figured that if he was taking the time to make a coro fan, that he would want a perfect half circle. If there are 17 spaces with his 16 channels, there won't be any lights at the 9 and 3 positions. Maybe that is what he wants, but I did not think so. Link to comment Share on other sites More sharing options...

Guest guest Posted May 25, 2012 Share Posted May 25, 2012 Understood; i totally get where you got your numbers and recommended separation. But again, I'm just going with what he showed us in the diagram...If you put strings at 9 and 3, then yes, would be 15 spaces, and I'd agree with the 8.5 inches.(and its been a long week, so no "jim swinder" cheap shots come to mind at the moment...:X:D:D) Link to comment Share on other sites More sharing options...

My bad. In my defense I was getting ready to leave work on a 3 day weekend and I wasn't thinking straight.Lori P is right. I do want strings at 9 and 3 o'clock positions. I actually came up with 8.53" after I got home too. This, mind you, is before I saw these posts. Anyway, thanks for all the comments. It was very helpful. I now know what to do as far as calculating something like this now. Back to work in the morning on this as well as trying out the new CC pixels and a controller that is my first attempt at soldering a kit board.Ron Link to comment Share on other sites More sharing options...

You're original drawing would suggest that.Sounds like its strings at 9 and 3, and then 14 more in between.If that is the case, then yes, Lori P is absolutely correct.
