Every kitemaker seems to have a different way to add weight to a sport kite to make it more pitch happy.

Sky Burner had the right idea with the coin loader, but I don't hear about it anymore, nor know if it is still being implemented.

A post 1982 penny weighs 2.5 grams.
A nickel weighs 5 grams.

I need some little thingamajig that will hold various combinations of pennies and/or nickels which can be tied to the spine or velcro and stay in place.

Something like a Barbie Doll's seamed nylons (yeah, I watch too many old movies) would work.

Any ideas on what the correct doohickey is?

Note that for 6˘, you can have a 15 gram tail weight. That's got to be cheaper than all these tubes and machined parts I've been seeing.

Or roll a bit of lead flashing around the bottom of the spine?
Easy to fit/adjust and requires no special parts

Coils of solder are pretty cheap and easy to fit

I have used velcro with success. Also, a couple snug  orings on the spine with brass spacers from local hardware store.

If you are in a sporting good store, you can always gander by the fishing weights section. Many different shapes and sizes to choose from. Once you see them I am sure that the ideas on how to attach them should start to fire up.  Do be careful with lead and where it may possibly end up. It is not the safest metal out there.
good luck,

Depending on how much weight you need to use, I've had some success with a modified HQ Yoyo stopper.



I tapped a thread on the 'peg' ( using a small nut) you can then put a couple of washers on and hold them in place with a locknut. Works up to about 15 grams or so depending on the size of the washers. Also has the advantage you can put the weight wherever you want on the spine.

I would have never thought of threading a fitting with a nut - great idea.
THanks!

I can't add much, except some help with your math...
15 grams of weight will cost you 12 cents John.    Grin Grin

I think John's referring to 6 pennies. Not exactly practical.

Copper tubing is inexpensive too and either the 3/8" or 5/16" OD will fit over most spines and fit inside most Velcro tail pieces. Take a spar down to your local hardware store and test fit it. It's sold by the foot at any hardware or plumbing store, should be around a buck a foot. A small O ring or piece of 1/4" ID Vinyl or rubber hose will keep it from sliding up the spine, usually the same isle at the hardware store. Probably set you back a few bucks to get enough to weight a dozen kites. Cut it into various lengths for experimenting. I forget what Anthony (Ca Ike) said it weighs per inch but he'll probably chime in. Of course you should invest in a tubing cutter ($8) but you can use a hacksaw in a pinch since you won't be looking for a good seal. Very much like a Blue Moon kit, just not as pretty.

I've successfully stuffed a Nickel or two into the Velcro tail piece on some kites that were not specifically designed for that. I've also lost a few Nickel's doing that.

You chaps are not getting with the program here. My goal is a weight system that costs less than a dime.

I'm thinking that my doohickey will be a tube

BALLOON.

Shove some pennies into the middle and tie the 2 ends together. If I get a black balloon, you probably won't even see it tied to the keel material.

I'll post some pictures.

A balloon feels appropriate for making a Weeble™ kite add-on anyway.  Smiley

You could make a Velcro pocket, hooks on one side and loops on the other, to slip the coins into. Very similar to the Skyburner weight system since it would then go between the existing velcro closure, but the sides would be closed and one end open unlike the Skyburner system with ends sewn and sides open. I like that system because it's quick to remove the weight, I don't like adding bulk right there and worry about its security but I've never had mine come undone.
