Bamboo Arrow Build-A-Long
First go to Home Depot and buy some 72" Bamboo Plant Stakes. They come in a 6 pack. Buy as many as you like expecting to get 3-4 usable shafts per bag.
You will also want to pickup some 16D Duplex Nails.
Now go through the bags and pickout the straightest pieces with a OD (outside diameter) of between 7-10mm. It helps to have an open end wrench handy to help gauge the OD. We are going to be making these into 32" shafts so the OD only needs to be between 7-10mm for a 32" section.
You should now have a pile of hand picked 72" Bamboo Plant Stakes with an OD of between 7-10MM over a 32" section.
Now we need to cut the Bamboo Plant Stakes down so they are more manageable for the straightening process. Bamboo likes to split when being cut so be careful here and use a sharp/fine tooth saw.
When cutting the Bamboo you need to find the best section of your 72" stake. Bamboo has a natural taper. The thick end of you bamboo is going to have the point. The thin end will have the nock. Take this into account when cutting the Bamboo. You will want your cut at the nock end to be about 1.5" past a node. We will be using the node to help setup the Self-Nock later on. Go ahead and cut the shafts down to only about 36-40" at this point. You want to leave them a little long to help with straightening.
In the pic below you can see where you want to have the cut for the nock end in relation to the Bamboo node.
For straightening the shafts I like to use a heat gun. Just about any heat source will work.
Some people like to straighten the nodes first. Some like to do the mid section first. It does not seem to matter either way so choose which one you like. I start with the nodes.
I take my heat gun and place it under the node while spinning the shaft. Once the section I am heating gets hot enough the Bamboo will bend very easy. Just bend it as straight as possible and move on to the next node.
After you do the nodes move on to the section between the nodes.
