Ash age hardening ?

Ok . Thanks for that .

Ok . Thanks for that .

 

So you are both right, unless I'm wrong...

Anyone care to guess what moisture content will be for this ash.

8 inch diameter air dried for a year or so outside then logged in the summer and stacked at the back of an open shed for 2.5 years

Hi CORNISH 10% may be less thanks Jon

Yes we are both right . As the wedge penetrates , bending the fibers there is tension on the outside of the curve but compression on the inside of the curve

Well, I don't have a splitter, only a very sharp maul.

 

But I guess, a hydraulic splitter has a wedge with a double bevel and a ram that pushes the log onto the wedge, which is then forced into the timber slowlyish and parts the fibres.

 

So there is an element of compression at the bevel and tension down beneath that, where the log splits. Whether there are more compressive forces than tensile forces, or that they are the same, and which of them makes the chips fly is a matter for someone more savvy than me.

 

But I reckon your moisture content is about 18%.

I suspect you will be a lot closer than Jon. I have weighed 4 samples from 2 logs. 2 centre and 2 outside samples. All are drying in a slow oven at present.

Hi CORNISH did you say they were cut ringed up for 2 years then into logs for 1)2 years in a good air barn or stillage you could 10)15% thanks Jon

Hi Cornish when did you take the moisture readings 2 1/2 years after you cut the logs up and stack them in the shed or after they were just rings up and then split them the most you're tested it would be a lot higher thanks John
