I posted about a week ago trying to figure out what kind of wood I had purchased…maple vs. hackberry, versus honey locust, etc. in this thread: http://lumberjocks.com/topics/37862
Anyway, the question of wood type made me think that it would be cool to try and test out the hardness of some wood on my own, so I bought a Dillon 5000lb force tested on ebay for cheap money and a couple of 11mm (0.433”) diameter bearing balls from ebay. Also, got a little $1.50 block of honey locust to test out. The janka test calls for .444” balls i think… close enough
The kicker is, as soon as I cranked on the handle from my mystery wood, it split into two pieces! will have to wait till tomorrow to get another piece. arg
Not sure if this is the correct way to do it, but what the heck.
Hard maple = ~1100:
Small honey locust block ~1600, accepted value from the chart 1580:
The results from (what i was told was Macassar ebony). ~3100, accepted value ~3250 I had to REALLY crank to get the last 1/4 turn.
