That is an amazing accomplishment. Did you have to make lots of arrows and then pick a few that flew true, or is it easy to make just a few and have them shoot consistently alike?
I only have about 5 arrows. They are not hard to make right but are time consuming. Here is how i do it.
I find cane that is about a big as my finger at the base and about 8 feet tall. I cut a bundle of at least a dozen and tie them tightly together. Once they are dry i pick out the straightest ones. I then move up the cane finding the length that feels like the right spine. I cut it out leaving a foot on each end of what is to be the arrow. I then heat straighten the cane with a propane torch. To do this i heat the area to be straightened by quickly spinning it over the flame until it sweats. The cane will feel like rubber at this point and you can bend it straight and hold it intil it cools and it will keep the new shape. Once the shaft is straight i sand down the nodes some. You can sand them down smooth but it makes for weak spots. I leave mine proud. If the spine is right the arrow shouldnt be touching anything when its released.
I use a self nock and 2 different types of fletching. I like the 3 wing feathers best but also the split shaft tail feather. To do the split shaft i make the nock then rest my knife in the bottom of the nock and force a split. Since the shaft is hollow the quill will fit inside. Once you put the whole tail feather inside the split you lash it back together.
The cane arrows are tougher than store bought arrows of any material. I am amazed at what kind of beating cane can take.
Making a bow is easy compared to making good arrows.
