Dacron line in 50 pound strength is ideal for these Dowel Series kites.
the construction details for the bridle are contained in the large
photo below. Look and read carefully, and you can't go wrong on this
rather important bit!
If you are new to this, you might need instructions on how to tie the following knots:
Double Wrap Slip Knot
TIP: Secure the slip knots onto the dowels with enough wood glue to ensure the knots can never slip along the dowel. They won't loosen either.
Once your kite and bridle looks like the photo up there:
Hold the short bridle line up so all the bridle lines are straight, with the kite laying flat on the table or floor.
Make sure the Prusik knots closest to the kite are adjusted to the middle. Right over the vertical spar.
Referring to the diagram below, shift the highest Prusik knot to the shown position. It's not necessarily the perfect position for your individual kite, but it should at least fly on the first attempt! Later, you can experiment with shifting the position towards or away from the nose, a little at a time, to improve how high your kite flies.
Make up a flying line and attach it to the bridle with a Lark's Head knot. See the photo, where the Lark's Head has been left loose.
Check the bridle slip knots on the horizontal spars. Retighten if necessary, or put a small drop of wood glue on each so they can never come loose. You won't have to wait the full drying time for this glue to dry, since the amounts are small.
Firstly, if it's very windy outside, stay home!
This is a light-wind kite and won't like being launched in a gale or even a fairly fresh breeze. If the wind is too strong, it will deform badly and refuse to fly properly.
The Prusik knot on the bridle line can loosen off a little over time. If necessary, pull on all the lines to tighten the knot up before a flying session.
Assuming there is some breeze outside, just dangle the kite at arm's length until the wind catches it. As long as you feel the kite pulling, let out line slowly by taking loop after loop off the winder.
Be cautious about letting line slip through your fingers. If a big gust hits the kite, the line could burn you! For any kite this big or bigger, it's a good idea to wear a glove of some sort.
Another approach is to get a helper to hold the kite up and let it go, on the end of 10 or 20 meters of line. This way, the kite soon gets high enough to make it easy to let more line out.
Have fun flying, and I hope you've enjoyed learning how to make a rokkaku kite!
