I've made a few ramrods from splits, Hickory, Red Eld, Osage,....and one from a salvaged 3 pc. bamboo fly rod mid section. I've also made a few bamboo flyrods. And,...a few arrows from 'Martha Stewarts'.
No way would I make a ramrod from a 'Martha Stewart', primarily due to not having the node(s) reinforced.
I might think about making a rod from bamboo split, turned 180* then reglued....... OK, I've thought about it. Naw........
