I am out here in the desert where the humidity often drops into the single digits. Can this damage a bamboo rod by causing stress/separation between the fibres
and the glue lines or weaken ferrule bonding to the bamboo? Glenn

Hi guys, Yes, I think. I also live in dry climate, the high country of Colorado. I think shrinkage affects ferrule to bamboo fit. I haven't seen
de-lamination problems. Jay Edwards

I really don't know, but seems I've read that dry, low humidity climes are best in terms of weather related problems with bamboo?

I used to live in the humid NE, now stuck in the desert SW. Just this non-rodmaker's opinion, but if the rod is properly varnished (or impregnated)
it's well sealed and no appreciable amount of atmospheric moisture should be able to enter or exit the blank.
I could see how the typical cracks in the varnish around the ferrules could be a potential problem, I regularly touch up those wraps. |

No coating will stop wood or bamboo from eventually stabilizing with it's environment. According to the Forest Service study, paraffin wax works better
than anything else, but even that won't stop moisture from equalizing. Old furniture and old rods will come to the most harm from dryness, keep the finish
in good shape and keep the rod waxed and it will help a lot. New rods with new finish and modern glues will hold up best to extremes in climate.

I have a new made three piece rod that after a few months in our dry Santa Fe climate started to hinge at all the female ferrules. I contacted the maker and
he requested I send the rod back to him for repair. Seems different types of epoxy/glues used in attaching the ferrules shrink in dry climates. He used a non
shrinking or non water base epoxy to fix. So far they are holding up well. KERMIT

John, I tend to agree. I have built furniture/clocks in the past, 60s and 70s. I observe these things change over the years. The most moist environment
I've lived in was Washington state, Skagit river area, and here, southern NM is the driest. As I know how my furniture joints were constructed, the changes
in the joints were slowest and least when movement was allowed for in the design. On a bamboo rod the ferrule would be susceptible. Moisture is important. Even
slight amounts. Horses hooves here are a similar item with lack of moisture. Extreme dryness causes problems. Yesterday a vet, also a horseshoer said that if a
horse walks across wet ground once a month it will make a difference. So, I don't mind when I see a picture posted that depicts a submerged fish and rod.
It is probably good for the rod to get a dunking once in awhile. Glenn

Tom Morgan actually did a test of this situation in his shop. He took a finished butt section, dipped it in four coats of varnish, then let the varnish cure.
Once cured he marked the .250 dimension on the section and put it in a humidity cabinet at 75% humidity (from an ambient humidity of about 25%). After 10 days
the section had swelled by nearly 5%. After removing the section, it returned to its previous dimensions in a few days.
So, as John says, varnish will not prevent bamboo from taking in (or shedding) moisture and equalizing with the environment. If you get a rod from a moist climate and bring it to the desert (like here in S. Colorado or NM), my bet is that it is going to shrink a bit. Cheers, Jay |

Interesting jayhake...we learn something every day.
FWIW, I have two rods made, and used for years, in the East, so far at least (6 years+) no problems from the arid climate. |

Just wanted to add my experience. I have several rods (Grangers, Heddons, Montagues & 1 Doug Kulick Kane Klassic that I have since sold) that made the move
from Corpus Christi, Texas (very humid) to San Antonio, Texas to El Paso, Texas and ultimately Tucson, AZ where they now reside. I never had a problem with the
ferrules on the older rods, but a couple of rods I restored in Corpus & San Antonio did hinge a bit - I used ferrule cement and just reset them. I have had
some wraps drying, but really think that is more a function of aging. One thing I am noticiing is that ridges on my grips seems to be accelerating a bit on my
oldest rods. Anyone else in the desert see this? Gilbert in Tucson
