I spent some more time & extra effort, trying to see if bamboo would make decent ramrods. So, taking the face layers off of some salvage engineered bamboo paneling I had kicking around, and then gluing them together, resawing them into 3/8" strips and finally machining them round.
The results - perfectly straight grain, no runout, & somewhat flexible. Good so far.
The test - Holding the ends & seeing how far they would bend. FAIL! I found that the weak spot on the outside of the bend was the node, which was every 6-10" on each individual strip of bamboo. That was where they always failed & turned into a bunch of long splinters.
Conclusion - Every one who said 'stick with hickory', was right. Bamboo seemed to have all the right characteristics, but, with the final test, proved completely unsatisfactory for this use.
