Last month to process logs to sell this coming Winter ?

[skyhuck]

i bet they will be sub 20% in less than 3 weeks

 

In this weather yes, but in October when is raining:sneaky2: I'm not so sure.

they will be in nets and into the polytunnel for selling Oct/Nov time

If stored correctly it will it works for me so why not others??????

 

Do tell dear felloo

They will be cracking firewood by then

I'll calculate their actual moisture content in the morning and will hang them in a sheltered spot to see how dry they get before October.

 

Here are the figures and picture after 8 days drying, the birch was much smaller and higher proportion of surface area which may explain why it is drying fastest.

Interesting mate, especially the way the Ash and Birch graph lines cross so quickly. Suggests that if you need firewood today ash is best but if you can wait til next week birch is better. As expected oak needs the longest seasoning time. I'd like to see a graph for conifer too, something like scots would be telling.

I thinks the reason for the birch drying quicker is that it was half the size of the oak and ash.

 

I can do some scots as we had a demo of a shear at work on Friday and a scots was felled.

 

If I get enough round tuits I shall do it again with 4 species and get the sizes nearer the same plus run a datalogger alongside.

Well the surface area to volume calculation is certainly going to have an impact however my suspicion is that the birch would dry faster even if all the logs were the same size.

 

More tests would be great

And here is the result so far with a couple of other species added. Please note my original oven dry weights based on 30 gram samples seem inaccurate so I won't have the correct figure until I actually put the 5 specimens in the oven for 24 hours at 120C, so look on the figures as being indicative and up to +-10% of the current value either side e.g the birch is probably in the area 8-10% wwb at the moment..

 

 

So if I can get enough airflow through my heap and covered it looks like I only need about 3 weeks in the summer to season for my home needs yet I've always been worried about not having enough cut by end of May.

Latest weighing, you can see how drying slowed in the wet part of the summer and now weights are on their way up again. Pine seems to be most sensitive to ambient humidity
