I get by OK with the common dowel rods from the hardware store, some birch and some ramin, even though I load very tight patch and ball combos like .495" balls with .027-.033" denim patch. A friend has broken five of Track's hickory rods while I've broken none of the dowel rods.
Maybe it's technique, I tend to drive the ball down with several short tamping motions while my friend likes to grasp the rod high and press down with one swoop.
I'm sure straight grained hickory is best but it is really hard to find truely straight grain and any runout is a weekness. The ramin dowels are a much softer wood but generally straight grained and therefore stronger.
I wonder what the mountainmen used when they broke or lost a rod? Not much hardwood in the Rockies and nothing straight.-- :hmm:--I do wonder.
Hey maybe that's it, maybe they ordered a "wonder rod".-- :: ::
