FTOTY 2005 Bamboo Rod Build
Posted 06 October 2005 - 10:09 PM
All of the nodes on our split strips look like the image below. We need to smooth and flatten these out before we proceed.
For expediency's sake, rather than use a file to smooth the nodes, I prefer to use a belt sander mounted on its side outfitted with 120 grit paper.
The pith, or inner, side of the node is flattened first.
I then, very, very carefully smooth out the enamel side. I take off just enough to remove most of the nodal hump. Most nodes will still require some flattening after they've been sanded flat.
Once finished, the node is fairly flat.
A finished batch of strips ready for straightening!

|Assuming a 2 tipped rod what do you do with all the extra pieces of cane from the lower half of the culm?|
They end up in the ever-growing pile in the corner of my garage!
|why not heat and press the nodes flat?|
Actually the sanding simply replaces the 'Planing Diaphragm Ridges' step in Cattanach's book. I'll be heat/vice pressing the nodes as well.

Actuallly after straightening, I use the sand belt again, to shape the splitted strip closer to 60 degees to make the rough planing easier/faster.
Is the enamel more easy to remove from the bamboo when itīs flamed, than if oven heat treated only?

Here is a node that would take a lot of sanding to get flush and smooth. More than I would feel comfortable doing, so it is these types of nodes that I'll press. Also notice the path of the power fibers at the node before and after straightening.
To straighten a node I hold the bent area over a heat gun for anywhere from 30 seconds to 1 minute, until it becomes slightly pliable. I'll then clamp it into a smooth jawed vice and leave it there for a minute or so to cool.
Below is the node after heating and pressing. The charred portion is very shallow and will be beveled off in the next step.
The other type of bend that needs work is a side-to-side twist as shown below:
The same node in the vice after heating:

A question about sanding, I have a 1" belt sander, are there any do nots concerning the direction of sanding? Do you have to sand along the length to avoid chipping?

The first step is to run the strips through a beveler which, after a number of passes, gives the strips their initial angles. For each section I stop beveling when they are approximately .040" over the maximum final strip diameter for each section.
Once beveled the strips are arranged according to the color code we set up earlier, rolled up and bound.
The strips are now ready for heat treating.
For heat treating flamed rods, I usually do 12 minutes in a 375* oven flipping them end to end at the 6 minute mark. This removes the remaining moisture and further tempers the cane. When the strips come out of the oven they are quite floppy due to the heat and once cooled will be fairly straight.
