If you have problems with spars splitting at the joint you can thread wrap em, to add hoop streingth.
I got to get some photos up and another thread started on thread wrapping...
It is TEDIOUS but it does look good and serve a useful purpose...

Stan,
Thanks that's what I needed to know... 
Squid,
There is a large Cellualar kite in Maxwell Edens book... can't remember the name, but the plan mentions that the joint ends of the spars should be thread wrapped.
I would enjoy seeing a thread (no pun intended) and pictures of this process..
Cheers,
Bill |

I think it is the "Stone Mountain Kite" you are referring to.... that was the old mans first cellular piece! The thread wraps in that kite are used to hold on the "fishing" quides. The guides are used to form a "truss system" to strengthen the light weight spar.
The kite was designed as an ultralight fast climber by Bobby Stanfield. At the time there was a contest in Stone Mountain GA (SteveD?) for the fastest climbing kite. Bobby won with this design.
Yes, we will have to work on a pictorial tutor on how to thread wrap. Squid, hold off a while on this, I think i have some documentation on file.... in an old KBI Journal I think. There was also some work done by Glenn and Tanna for a Kite Lines article on thread wrapping that was never published. I'll see if I can get permission to use it here.
-Steve

Most public libraries have boos on custom fising rod building and this is the most popular:
ADVANCED CUSTOM ROD BUILDING
By Dale Clemens
Look at any book by Dale Clemens. He used to sell all the parts you would ever need to build a rod but his store is out of buisness.
there are lots of places to buy the stuff needed but the basic techniques are neeed and the book is a great way to start.
Here are the basics on the web:
Wrapping The Rod
just to wet your appitite....
You then have to wet out with epoxy or other rod finish, which is a PAIN but if done right looks OUTSTANDING!!!!!!
I dont put on guides on my kites, I just thread wrap the ends to add hoop strengith and to make them look better.

Harold,
Have you used Kevlar thread for wrapping? I find it absorbs epoxy better than Spectra and comes in colors.

usually we use nylon thread for wrapping BECAUSE it has some stretch... you can wrap it down nice and tight.
Never tried Kevlar thread... but I know it doesnt stretch much!

I'm usually just trying to keep thin wall spars from splitting at internal Ferrels on stuntkites, nothing flashy. The Kevlar is as close as I can get to Carbon fiber, although there is a store here that sells Carbon ribbon. I'm just too lazy to drive ten miles to buy it.
Stan
P.S. I didn't type Ferrels that way!  |

I posted the following response in the Graphite Discussion thread just about the same time Steve started this thread...thought it might be worth the extra space to put a copy here...

**Yeah man!! I grew up in the shadow of that rock - never lived more than 5 miles away from it till I was in college! Flew plenty of kites from the top. Think they may still have some kite events there - need to check and find out.

**There is also some good information on thread wrapping on a couple of the flyfishing/rod building sites I visit now and then. Materials are similar and the process is identical. Can be a little tedious but its not all that hard to do - no rocket science. I'll try to take a look around later and post a link or two if I find something really useful..
