Yes, occasionally one will find a stringy ash. However, we've cut about 50 cord of it in the last 13 years and can recall only a very few that were stringy. Most times when using the hydraulics, the wedge goes in about an inch then up because the log has split already. Makes for fast splitting for sure.
All this ash talk is making me happy, happy, happy! I'm guessing I've got a cord bucked up, and another two cords in logs, and maybe 3 cords still standings in trees. Along with the two cords of oak, locust and cherry that will be ready next fall I should have a good supply next winter!
I have permission to scrounge probably ten cords of downed Ash, plus many more standing, barely alive Ash trees. About five or six cords so far are piled in my yard, and I'd have more but the winter weather hasn't been cooperative lately. I'll be burning Ash for the next few years. It splits more easily than almost any other hardwood, in my experience.
I'm burning some 10 year old indoor dried ash as I type this. Wish I could let it all season that long with out ever seeing a drop of water on it. The funny part is it feels just as heavy as fresh cut but burns like gasoline and lasts forever
