Wow, it’s been a while since I’ve been out fishing….been real busy in the shop with rod building. Mary Ann just finished building her second bamboo rod, a beautiful 7′ 9″ 4 wt Progressive Medium-Action rod. What a great taper…casts dries like a dream. She cast dry flies hard for a few hours while I took out my 9′ 0″ 3 wt Czech Nymphing rod with #20 zebra nymphs and Bead Head Pheasant Tail Nymphs. I picked up several fish on nymphs, but there was nothing hatching and she was fishless on dries. But, she eventually went over to small nymphs, and her new rod handled them great. And….she got several fish to the net. As her first fish on her new rod she picked up a nice 13” whitefish. After that, several feisty rainbows. Here are a few photos from our day.
Here we are on the Crooked River this past week.

Mary Ann has started building her second bamboo fly rod, so I now have two students in the shop working with me….keeps me pretty busy. She is building a very nice progressive 7′ 9″ 4 wt rod, perfect for dry flies on spring creeks. Here are a couple of photos from this past week.
I just started another Bamboo Fly Rod Building Class this past week. Charlotte, who is local to my area, wants to build her second bamboo fly rod….and this one will be for her husband, Dan….what a lucky guy! Charlotte built her first rod with me last year so it’s great she is launching into rod #2. This rod will be a fast action 8′ 0″ 6 wt rod, which will be great for Dan as he does a lot of lake fishing. Here area a few photos of Charlotte’s rod building process.
Like a number of bamboo fly rod builders, I use Pearsall’s silk thread from England for wrapping guides on all my rods. Pearsall’s is among the best quality silk thread in the world for bamboo fly rods. Unfortunately, Pearsall’s has done away with their finest silk thread and they no longer supply it. So, I’ve been picking up as much as I can from numerous WEB sites over the past month to restock my favorite colors. And, I’ve been lucky enough to stockpile enough spools to last me for several years. Here is a quick look at what I have:
I just received a new shipment of bamboo from my supplier in Seattle and thought a good post might be to talk a little about the bamboo we purchase for our bamboo fly rods.
The bamboo we use is a particular species that comes from a small region in China…it’s not your garden variety of bamboo that we use. There is a supplier in Seattle (the Bamboo Broker) who travels to China and hand selects the bamboo we use in our fly rods. The choice bamboo we use has some particular characteristics that I’ll get into later.
A piece of bamboo is referred to as “a culm”. When we order bamboo, it comes in 12 ft. lengths, and each piece is about 2 1/2 inches in diameter. It comes in bundles of 10 culms/bundle, and I usually order 3 or 4 bundles at a time. Including shipping costs, the cost for a single culm of bamboo ends up being about $40 each.
Three bundles of bamboo that I just ordered.
I’ll get quite a few rods from these 3 bundles of bamboo.
After we unpack the bamboo, the first thing we need to do is to put a “stress relief crack down the entire length of the bamboo culm. This is to relieve internal stresses that exist in the bamboo that could lead to excessive cracking later on. Sometimes a crack already exists when we receive the bamboo, and you see that in the two culms in the right of this photo. Because the bamboo fibers run the entire length of the culm, it’s pretty easy to make the stress relief crack. I accomplish this with large screw driver and hammer…banging the screw driver hard with the hammer will open the crack and then twisting the screw driver walks the crack down the length of the culm.

For quality bamboo, we’re looking for the following characteristics:
The bamboo should be relatively straight.
Fairly uniform color.
Minimal surface discoloration/anomalies.
Good spacing between the growth rings (nodes).
Also, one of the most important aspects in the bamboo is that each piece have a high concentration of “power fibers” at the outer surface of the bamboo. The power fibers are seen as the darker region towards the outer surface of the bamboo. It’s these power fibers that give the bamboo strength, and having a high concentration of power fibers is a good thing in bamboo fly rods. The white region visible at the inner surface of the bamboo is called the “pith”, and it has a spongy characteristic that isn’t desirable in bamboo fly rods.

In starting a bamboo fly rod, the 12 ft. long culm is first cut to the length of the individual rod sections (plus a few extra inches). Next, that culm is split into approximately 20 thin sections…but the details of that are for another post!
I now have a good supply of bamboo culms that should last me for a couple of years.
