The use of nodeless construction techniques for building bamboo fly rods has many benefits for the rodmaker. No special heat treating oven required. Building a nodeless rod is no longer the Herculean Feat or Holy Grail Rodmaking that the Garrison book made it appear. The construction techniques required have been updated and simplified. The average rodmaker can easily accomplish a nodeless rod in the same time or even less than it takes him to build a rod now.
Nodeless construction allows the rodmaker to view the culm differently.
The reason is that you manufacture your strips from short sections. My first rod was from a bad culm that had a serious burn mark from heat straightening done in China. The butt section would have been unusable for a noded rod. I cut this lower part of the culm off and discarded it. I now had a 9 culm.
