This is really fun - but isn't information about the janka of most species already fairly accessible online? [1].
I always assumed there was a slight degree of strength variance due to age, humidity of growth region, etc - but maybe having your own tester might come in handy for certain structural engineering cases where accuracy is crucial.

- thethirdone 5y agoI haven't checked, but I would assume the janka hardness of wood is not super tightly correlated with yield strength. I would expect a variation of 2x for a the janka hardness : strength ratio; some wood would be twice as strong or half as strong as you might expect from the hardness.
