Split Bamboo Rod Building Process & Checklist
This is hardly a new idea and is really for me than anyone else, but if you have any desire to build rods I hope this helps in some way.
One resource that I've used is the checklist that Wayne Cattanach has in his book "Handcrafting Bamboo Fly Rods". I've also taken advantages of the wisdom of other rodmakers that was presented in books, their websites and YouTube videos.
My preferred resource is from Harry Boyd's https://globalflyfisher.com/rod-building/bamboo-part-1
It's an in-depth narrative outline that I used in Harry's class.
As in his class, all examples will be for a 7' 6" (90") two piece rod.
Decide which taper you want to use so you'll know how long each section needs to be whether you
make a two piece rod or a three piece.
If you flame first and then file down to the enamel, you'll have straw colored gaps instead of the desired color.
Flame the Entire Culm...
...be it 12' or 6' to the desired appearance.
If you're happy with the existing straw color, skip this step.
Start from the butt, move along about 18" at a time and rotate the culm before you go another 18".
The longer you flame the culm the darker the rod will be.
Cut the Culm
The sections will ultimately need to be the same length - 45"
Before you cut, do some arithmetic:
45" + 2" + 2" (extra at each end for wiggle room) + 6" (node stagger) = 55" cut length.
Note: Often there is a node inches from the end of the butt of the culm. I'd cut it off. However, for the butt section the reel seat and grip will cover that node and overcome the it's inherent weakness.
However again, if you use butt strips for a mid-section, you'll wish you had cut the node.
Cut it off just to diminish any anxiety.
